Hereinafter, embodiments of a modeling apparatus and a modeling method will be described with reference to the drawings. An embodiment of a modeling apparatus and a modeling method will be described below using a modeling apparatus SYS capable of processing a workpiece W, which is an example of an object. In particular, an embodiment of a modeling apparatus and a modeling method will be described below using a modeling apparatus SYS that performs additional processing based on a laser build-up welding method (LMD: Laser Metal Deposition). In the additional processing based on the laser build-up welding method, the modeling material M supplied to the workpiece W is melted by the modeling light EL (that is, the energy beam having the form of light), so that the workpiece W is integrated with or integrated with the workpiece W. It is an additional process that forms a modeled object that can be separated from. However, the modeling system SYS may perform additional processing based on a method different from the laser build-up welding method. Alternatively, the modeling system SYS may perform arbitrary processing (for example, removal processing) different from additional processing. Note that the modeling apparatus SYS may be referred to as a modeling system.

Laser Overlay Welding (LMD) includes Direct Metal Deposition, Directed Energy Deposition, Laser Cladding, Laser Engineered Net Shaping, Direct Light Fabrication, and Laser Consolidation. Deposition, Shape Deposition Manufacturing, Wire-Fed Laser Deposition, Gas Through Wire, Laser Powder Fusion, Laser Metal Forming, Selective Laser Powder Remelting, Laser Direct - Also called casting, laser powder deposition, laser additive manufacturing, laser rapid forming.

In addition, in the following description, the positional relationship of various components that make up the modeling apparatus SYS will be described using an XYZ orthogonal coordinate system defined by mutually orthogonal X, Y, and Z axes. In the following description, for convenience of explanation, each of the X-axis direction and the Y-axis direction is the horizontal direction (that is, a predetermined direction in the horizontal plane), and the Z-axis direction is the vertical direction (that is, the direction perpendicular to the horizontal plane). and substantially in the vertical direction). Further, the directions of rotation (in other words, tilt directions) about the X-, Y-, and Z-axes are referred to as the .theta.X direction, the .theta.Y direction, and the .theta.Z direction, respectively. Here, the Z-axis direction may be the direction of gravity. Also, the XY plane may be set horizontally.

(1) Structure of Modeling Apparatus SYS First, the structure of the modeling apparatus SYS of the present embodiment will be described with reference to FIGS. 1 and 2. FIG. FIG. 1 is a system configuration diagram showing the system configuration of the modeling apparatus SYS of this embodiment. FIG. 2 is a cross-sectional view schematically showing the structure of the modeling apparatus SYS of this embodiment.

The modeling apparatus SYS can perform additional processing on the workpiece W. The modeling apparatus SYS can form a modeled object integrated with (or separable from) the work W by performing additional processing on the work W. As shown in FIG. In this case, the additional processing performed on the work W corresponds to the processing of adding to the work W a modeled object integrated with (or separable from) the work W. Note that the modeled object in the present embodiment may mean any object modeled by the modeling apparatus SYS. For example, the modeling apparatus SYS is a three-dimensional structure (that is, a three-dimensional structure having a size in any three-dimensional direction) as an example of a modeled object. , a structure having dimensions in the Y-axis direction and the Z-axis direction) ST.

When the work W is a stage 31 to be described later, the modeling apparatus SYS can perform additional processing on the stage 31 . When the work W is a placed object that is placed on the stage 31, the modeling apparatus SYS can perform additional processing on the placed object. The object placed on the stage 31 may be another three-dimensional structure ST (that is, an existing structure) modeled by the modeling apparatus SYS. Note that FIG. 2 shows an example in which the work W is an existing structure held by the stage 31 . Also, the description will be made below using an example in which the work W is an existing structure held by the stage 31 .

The work W may be a repairable item with a defect. In this case, the modeling apparatus SYS may perform repair processing for repairing the item requiring repair by performing additional processing for forming a modeled object to compensate for the defective portion. That is, the additional processing performed by the modeling apparatus SYS may include additional processing of adding a modeled object to the workpiece W to compensate for the defect.

As described above, the modeling apparatus SYS can perform additional processing based on the laser build-up welding method. In other words, it can be said that the modeling apparatus SYS is a 3D printer that models an object using the layered modeling technology. Note that the layered manufacturing technology may also be referred to as rapid prototyping, rapid manufacturing, or additive manufacturing.

The modeling apparatus SYS performs additional processing by processing the modeling material M using the modeling light EL, which is an energy beam. The modeling material M is a material that can be melted by irradiation with modeling light EL having a predetermined intensity or more. As such a modeling material M, for example, at least one of a metallic material and a resinous material can be used. However, as the modeling material M, other materials different from the metallic material and the resinous material may be used. The building material M is a powdery or granular material. That is, the modeling material M is a granular material. However, the modeling material M does not have to be granular. For example, as the modeling material M, at least one of a wire-like modeling material and a gaseous modeling material may be used.

In order to perform additional processing, as shown in FIGS. 1 and 2, the modeling apparatus SYS includes a material supply source 1, a modeling unit 2, a stage unit 3, a measurement device 4, a light source 5, and a gas supply source. 6 and a control device 7 . The modeling unit 2 and the stage unit 3 may be housed in a chamber space 83IN inside the housing 8. FIG.

The material supply source 1 supplies the modeling material M to the modeling unit 2 . The material supply source 1 supplies a desired amount of the modeling material M according to the required amount so that the required amount of the modeling material M is supplied to the modeling unit 2 per unit time for performing additional processing. do.

The modeling unit 2 processes the modeling material M supplied from the material supply source 1 to model a modeled object. The modeling unit 2 includes a modeling head 21 and a head drive system 22 to model a modeled object. Further, the modeling head 21 includes an irradiation optical system 211 and a material nozzle (that is, a supply system for supplying the modeling material M) 212 . In addition, although the modeling head 21 is provided with the several material nozzle 212 in the example shown in FIGS. 1-2, the modeling head 21 may be provided with the single material nozzle 212. FIG.

The irradiation optical system 211 is an optical system (for example, a condensing optical system) for emitting the modeling light EL. Therefore, the irradiation optical system 211 may be referred to as a beam injection section. Specifically, the irradiation optical system 211 is optically connected to the light source 5 that emits the shaping light EL via an optical transmission member 51 such as an optical fiber or a light pipe. The irradiation optical system 211 emits modeling light EL propagating from the light source 5 via the light transmission member 51 . The irradiation optical system 211 irradiates the shaping light EL from the irradiation optical system 211 downward (that is, to the -Z side). A stage 31 is arranged below the irradiation optical system 211 . When the work W is placed on the stage 31, the irradiation optical system 211 irradiates the work W with the emitted modeling light EL. Specifically, the irradiation optical system 211 forms a target irradiation area EA set on or in the vicinity of the workpiece W as an area irradiated (typically, condensed) with the modeling light EL. Light EL can be irradiated. Furthermore, the state of the irradiation optical system 211 can be switched between a state in which the target irradiation area EA is irradiated with the shaping light EL and a state in which the target irradiation area EA is not irradiated with the shaping light EL under the control of the control device 7. is. The direction of the shaping light EL emitted from the irradiation optical system 211 is not limited to directly downward (that is, coinciding with the -Z-axis direction). good too.

The material nozzle 212 is supplied with the modeling material M from the supply outlet 214 (for example, injected, jetted, ejected, or sprayed). For this reason, material nozzle 212 may be referred to as a material supply. The material nozzle 212 is physically connected to the material supply source 1 which is the supply source of the modeling material M via the supply pipe 11 and the mixing device 12 . The material nozzle 212 supplies the modeling material M supplied from the material supply source 1 through the supply pipe 11 and the mixing device 12 . The material nozzle 212 may pump the modeling material M supplied from the material supply source 1 through the supply pipe 11 . That is, the modeling material M from the material supply source 1 and the gas for transportation (i.e., pressurized gas, for example, an inert gas such as nitrogen or argon) are mixed in the mixing device 12 and then passed through the supply pipe 11. may be pumped to the material nozzle 212 via. As a result, the material nozzle 212 supplies the modeling material M with the gas for conveyance. As the carrier gas, for example, a purge gas supplied from the gas supply source 6 is used. However, gas supplied from a gas supply source different from the gas supply source 6 may be used as the carrier gas. In addition, although the material nozzle 212 is drawn in the shape of a tube in FIG. 2, the shape of the material nozzle 212 is not limited to this shape. The material nozzle 212 supplies the modeling material M downward (that is, to the −Z side) from the material nozzle 212 . A stage 31 is arranged below the material nozzle 212 . When the work W is mounted on the stage 31 , the material nozzle 212 supplies the modeling material M toward the work W or the vicinity of the work W. Note that the traveling direction of the modeling material M supplied from the material nozzle 212 is a direction that is inclined by a predetermined angle (an acute angle as an example) with respect to the Z-axis direction. good.

In this embodiment, the material nozzle 212 supplies the modeling material M to the irradiation position of the modeling light EL (that is, the target irradiation area EA irradiated with the modeling light EL from the irradiation optical system 211). Therefore, the target supply area MA set on or near the work W as the area where the material nozzle 212 supplies the modeling material M matches (or at least partially overlaps) the target irradiation area EA. ), the material nozzle 212 and the irradiation optics 211 are aligned. In addition, the material nozzle 212 may supply the modeling material M to the molten pool MP (see FIG. 3 etc. described later) formed by the modeling light EL emitted from the irradiation optical system 211 . However, the material nozzle 212 does not have to supply the modeling material M to the molten pool MP. For example, the modeling apparatus SYS may melt the modeling material M by the irradiation optical system 211 before the modeling material M from the material nozzle 212 reaches the workpiece W, and adhere the molten modeling material M to the workpiece W. .

The head drive system 22 moves the modeling head 21 under the control of the control device 7 . That is, the head driving system 22 moves the irradiation optical system 211 and the material nozzle 212 under the control of the control device 7 . The head driving system 22 may be called a head driving section. The head drive system 22 moves the shaping head 21 along at least one of the X-axis, Y-axis, Z-axis, θX direction, θY direction and θZ direction, for example. When the head drive system 22 moves the shaping head 21, the relative positions of the shaping head 21 and the stage 31 and the workpiece W placed on the stage 31 change. As a result, the target irradiation area EA and the target supply area MA (furthermore, the molten pool MP) move relative to the workpiece W.

The stage unit 3 includes a stage 31 and a stage drive system 32.

A workpiece W is placed on the stage 31 . For this reason, the stage 31 may be called a mounting section. Specifically, the workpiece W is placed on a placement surface 311 that is at least part of the top surface of the stage 31 . The mounting surface 311 is normally a surface along the XY plane. The stage 31 can support the work W placed on the stage 31 . The stage 31 may be capable of holding the work W placed on the stage 31 . In this case, the stage 31 may have at least one of a mechanical chuck, an electrostatic chuck, a vacuum chuck, and the like to hold the work W. Alternatively, the stage 31 may not be able to hold the work W placed on the stage 31 . In this case, the workpiece W may be placed on the stage 31 without clamping. The irradiation optical system 211 described above emits the shaping light EL during at least part of the period in which the workpiece W is placed on the stage 31 . Furthermore, the material nozzle 212 mentioned above supplies the modeling material M in at least one part of the period when the workpiece|work W is mounted on the stage 31. As shown in FIG.

The stage drive system 32 moves the stage 31 . Incidentally, the stage drive system 32 may be called a placement drive section. The stage drive system 32, for example, moves the stage 31 along at least one of the X-axis, Y-axis, Z-axis, θX direction, θY direction and θZ direction. The operation of moving the stage 31 along at least one of the θX direction, the θY direction, and the θZ direction includes at least one of the rotation axis along the X axis, the rotation axis along the Y axis, and the rotation axis along the Z axis. It may be considered equivalent to rotating the stage 31 around one. Therefore, when the stage drive system 32 can rotate the stage 31 along at least one of the θX direction, the θY direction, and the θZ direction, the stage drive system 32 may be called a rotation drive unit. Further, the operation of moving the stage 31 along at least one of the θX direction and the θY direction is equivalent to tilting the stage 31 (for example, tilting it with respect to the horizontal XY plane). Therefore, when the stage drive system 32 can rotate the stage 31 along at least one of the θX direction and the θY direction, the stage drive system 32 may be called a tilt drive section.

When the stage drive system 32 moves the stage 31, the relative positions of the shaping head 21 and the stage 31 and the workpiece W placed on the stage 31 change. As a result, the target irradiation area EA and the target supply area MA (furthermore, the molten pool MP) move relative to the workpiece W.

The measuring device 4 is a device capable of measuring (in other words, capable of measuring) at least part of the object to be measured. For this reason, the measuring device 4 may be referred to as a measuring device. The measuring device 4 is a device capable of measuring at least a part of the characteristics of the object to be measured. Specifically, the measuring device 4 can measure at least a partial shape (especially a three-dimensional shape) of the measurement target as at least a partial characteristic of the measurement target. An example of such a measuring device 4 is a three-dimensional measuring machine (in other words, a 3D scanner) that three-dimensionally measures an object to be measured. In this case, the measurement device 4 projects a light pattern on the surface of the object to be measured by irradiating it with the measurement light ML, and uses a pattern projection method or a light section method for measuring the shape of the projected pattern. , the object to be measured may be measured. Alternatively, the measurement device 4 projects the measurement light ML onto the surface of the object to be measured, measures the distance to the object from the time it takes for the projected measurement light ML to return, and measures the distance from a plurality of positions on the object. The measurement object may be measured using the time-of-flight method performed in . Alternatively, the measuring device 4 may be a moire topography method (specifically, a grid irradiation method or a grid projection method), a holographic interferometry method, an autocollimation method, a stereo method, an astigmatism method, a critical angle method, and a knife edge method. At least one of them may be used to measure the measurement object. At least one of the workpiece W, the modeled object, and the stage 31 can be given as an example of the object to be measured.

The light source 5 emits, for example, at least one of infrared light, visible light, and ultraviolet light as modeling light EL. However, other types of light may be used as the shaping light EL. The shaping light EL may contain a plurality of pulsed lights (that is, a plurality of pulsed beams). The shaping light EL may be laser light. In this case, the light source 5 may include a laser light source (for example, a semiconductor laser such as a laser diode (LD: Laser Diode). Examples of laser light sources include fiber lasers, CO ₂ lasers, YAG lasers, excimer lasers, and the like. However, the shaping light EL may not be laser light.The light source 5 may be any light source (for example, at least one of LED (Light Emitting Diode) and discharge lamp). may contain.

The gas supply source 6 is a purge gas supply source for purging the chamber space 83 IN inside the housing 8 . The purge gas contains inert gas. Examples of inert gas include nitrogen gas and argon gas. The gas supply source 6 is connected to the chamber space 83 IN via a supply port 82 formed in the partition member 81 of the housing 8 and a supply pipe 61 connecting the gas supply source 6 and the supply port 82 . The gas supply source 6 supplies the purge gas to the chamber space 83IN through the supply pipe 61 and the supply port 82. As shown in FIG. As a result, the chamber space 83IN becomes a space purged with the purge gas. The purge gas supplied to the chamber space 83IN may be exhausted from an exhaust port (not shown) formed in the partition member 161 . Incidentally, the gas supply source 6 may be a cylinder containing an inert gas. When the inert gas is nitrogen gas, the gas supply source 6 may be a nitrogen gas generator that generates nitrogen gas using the air as a raw material.

As described above, when the material nozzle 212 supplies the building material M together with the purge gas, the gas supply source 6 may supply the purge gas to the mixing device 12 to which the building material M from the material supply source 1 is supplied. good. Specifically, the gas supply source 6 may be connected to the mixing device 12 via a supply pipe 62 that connects the gas supply source 6 and the mixing device 12 . As a result, gas source 6 supplies purge gas to mixing device 12 via supply tube 62 . In this case, the molding material M from the material supply source 1 is supplied (specifically, , pumped). That is, the gas supply source 6 may be connected to the material nozzle 212 via the supply pipe 62 , the mixing device 12 and the supply pipe 11 . In that case, the material nozzle 212 will supply the building material M together with the purge gas for pumping the building material M.

The control device 7 controls the operation of the modeling device SYS. For example, the control device 7 may control the modeling unit 2 (for example, at least one of the modeling head 21 and the head driving system 22) provided in the modeling device SYS so as to perform additional processing on the workpiece W. For example, the control device 7 may control the stage unit 3 (for example, the stage drive system 32) included in the modeling apparatus SYS so that the workpiece W is additionally processed.

The control device 7 may include, for example, an arithmetic device and a storage device. The computing device may include, for example, at least one of a CPU (Central Processing Unit) and a GPU (Graphics Processing Unit). A storage device may include, for example, memory. The control device 7 functions as a device that controls the operation of the modeling apparatus SYS by the arithmetic device executing a computer program. This computer program is a computer program for causing the arithmetic device to perform (that is, to execute) an operation to be performed by the control device 7, which will be described later. In other words, this computer program is a computer program for causing the control device 7 to function so as to cause the modeling apparatus SYS to perform operations described later. The computer program executed by the arithmetic device may be recorded in a storage device (that is, a recording medium) included in the control device 7, or may be stored in any storage device built in the control device 7 or external to the control device 7. It may be recorded on a medium (for example, hard disk or semiconductor memory). Alternatively, the computing device may download the computer program to be executed from a device external to the control device 7 via the network interface.

The control device 7 may control the emission mode of the shaping light EL by the irradiation optical system 211 . The emission mode may include, for example, at least one of the intensity of the shaping light EL and the emission timing of the shaping light EL. When the modeling light EL includes a plurality of pulsed lights, the emission mode includes, for example, the emission time of the pulsed light, the emission period of the pulsed light, and the ratio between the length of the emission time of the pulsed light and the emission period of the pulsed light. (so-called duty ratio). Furthermore, the control device 7 may control the movement mode of the modeling head 21 by the head drive system 22 . In this case, the control device 7 may be called a head movement control section that controls movement of the modeling head 21 by the head drive system 22 . The control device 7 may control how the stage 31 is moved by the stage drive system 32 . In this case, the control device 7 may be referred to as a stage movement control section that controls movement of the stage 31 by the stage drive system 32 . The movement mode may include, for example, at least one of movement amount, movement speed, movement direction, and movement timing (movement period). When the stage drive system 32 moves the stage 31 so that the stage 31 rotates as described above, the control device 7 may be referred to as a rotation control unit that controls the rotation of the stage 31 by the stage drive system 32. good. In this case, the movement mode of the stage 31 may include the rotation mode of the stage 31 . The rotation mode may include at least one of rotation amount (for example, rotation angle), rotation speed, rotation direction, and rotation timing (rotation timing). Further, when the stage drive system 32 moves the stage 31 so that the stage 31 is tilted (for example, tilted with respect to the horizontal XY plane) as described above, the controller 7 controls the stage drive system 32 may be referred to as a tilt control section that controls the tilt of the stage 31 by In this case, the movement mode of the stage 31 may include the tilt mode of the stage 31 . The tilt mode may include at least one of tilt amount (for example, tilt angle, typically tilt angle with respect to horizontal XY plane), tilt speed, tilt direction, and tilt timing (tilt timing). good. Furthermore, the control device 7 may control the supply mode of the modeling material M by the material nozzle 212 . The supply mode may include, for example, at least one of supply amount (especially supply amount per unit time) and supply timing (supply period).

The control device 7 does not have to be provided inside the modeling apparatus SYS. For example, the control device 7 may be provided as a server or the like outside the modeling apparatus SYS. In this case, the control device 7 and the modeling apparatus SYS may be connected via a wired and/or wireless network (or data bus and/or communication line). As a wired network, a network using a serial bus interface represented by at least one of IEEE1394, RS-232x, RS-422, RS-423, RS-485 and USB may be used. A network using a parallel bus interface may be used as the wired network.

A network using infrared rays may be used as the wireless network. A network using optical communication may be used as the wireless network. In this case, the controller 7 and the modeling apparatus SYS may be configured to be able to transmit and receive various information via a network. Also, the control device 7 may be capable of transmitting information such as commands and control parameters to the molding device SYS via a network. The modeling apparatus SYS may include a receiving device that receives information such as commands and control parameters from the control device 7 via the network. The modeling apparatus SYS may be equipped with a transmission device (that is, an output device that outputs information to the control device 7) that transmits information such as commands and control parameters to the control device 7 via the network. good. Alternatively, a first control device that performs part of the processing performed by the control device 7 is provided inside the modeling apparatus SYS, while a second control device that performs another part of the processing performed by the control device 7 is provided. The control device may be provided outside the modeling apparatus SYS.

A computing model that can be constructed by machine learning may be implemented in the control device 7 by the computing device executing a computer program. An example of an arithmetic model that can be constructed by machine learning is an arithmetic model that includes a neural network (so-called artificial intelligence (AI)). In this case, learning the computational model may include learning neural network parameters (eg, at least one of weights and biases). The control device 7 may control the operation of the modeling apparatus SYS using a computational model. In other words, the operation of controlling the operation of the modeling apparatus SYS may include the operation of controlling the operation of the modeling apparatus SYS using the arithmetic model. Note that the control device 7 may be equipped with an arithmetic model that has already been constructed by off-line machine learning using teacher data. Further, the arithmetic model installed in the control device 7 may be updated by online machine learning on the control device 7 . Alternatively, in addition to or instead of the computational model implemented in the control device 7, the control device 7 may use a computational model implemented in a device external to the control device 7 (that is, a device provided outside the modeling apparatus SYS). may be used to control the operation of the modeling apparatus SYS.

It can be implemented in the form of

(2) Operation of modeling apparatus SYS Next, the operation of the modeling apparatus SYS will be described.

(2-1) Basic Operation of Additional Machining First, the basic operation of additional machining performed on the workpiece W by the modeling apparatus SYS will be described. The additional processing performed on the work W corresponds to an operation of forming a modeled object so as to add to the work W a modeled object integrated with (or separable from) the work W. FIG. In the following, for convenience of explanation, additional processing for forming the three-dimensional structure ST, which is a modeled object having a desired shape, will be explained. As described above, the modeling apparatus SYS models the three-dimensional structure ST by performing additional processing based on the laser build-up welding method. Therefore, the modeling apparatus SYS may model the three-dimensional structure ST by performing existing additional processing based on the laser build-up welding method. An example of the operation of forming the three-dimensional structure ST using the laser build-up welding method will be briefly described below.

The modeling apparatus SYS models the three-dimensional structure ST on the workpiece W based on the three-dimensional model data (in other words, three-dimensional model information) of the three-dimensional structure ST to be modeled. As the three-dimensional model data, a measuring device (for example, the measuring device 4 or another measuring device different from the measuring device 4) provided in the modeling device SYS and a three-dimensional shape measuring device provided separately from the modeling device SYS At least one measured data of a three-dimensional object may be used. In order to form a three-dimensional structure ST, the modeling apparatus SYS sequentially forms, for example, a plurality of layered partial structures (hereinafter referred to as “structural layers”) SL arranged along the Z-axis direction. For example, the modeling apparatus SYS sequentially models the plurality of structural layers SL one by one based on the data of the plurality of layers obtained by slicing the three-dimensional model of the three-dimensional structure ST along the Z-axis direction. To go. As a result, a three-dimensional structure ST, which is a laminated structure in which a plurality of structural layers SL are laminated, is formed. Note that the structural layer SL does not necessarily have to be a modeled object having a layered shape. The flow of operations for modeling the three-dimensional structure ST by sequentially modeling the plurality of structural layers SL one by one will be described below.

First, the operation of modeling each structural layer SL will be described with reference to FIGS. 3(a) to 3(e). Under the control of the control device 7, the modeling apparatus SYS controls the modeling head so that the target irradiation area EA is set in a desired area on the modeling surface MS corresponding to the surface of the workpiece W or the surface of the structural layer SL that has already been modeled. At least one of 21 and stage 31 is moved. After that, the target irradiation area EA is irradiated with the shaping light EL from the irradiation optical system 211 . At this time, the condensing position where the shaping light EL is condensed in the Z-axis direction may coincide with the shaping surface MS. Alternatively, the condensing position may be off the modeling surface MS in the Z-axis direction. As a result, as shown in FIG. 3A, a molten pool (that is, a pool of metal or the like melted by the shaping light EL) MP is formed on the shaping surface MS irradiated with the shaping light EL. Furthermore, as shown in FIG. 3B, the modeling apparatus SYS supplies the modeling material M from the material nozzle 212 under the control of the control device 7 . As a result, the modeling material M is supplied to the molten pool MP. The modeling material M supplied to the molten pool MP is melted by the modeling light EL irradiated to the molten pool MP. Alternatively, the modeling material M supplied from the material nozzle 212 may be melted by the shaping light EL before reaching the molten pool MP, and the molten modeling material M may be supplied to the molten pool MP. After that, when at least one of the modeling head 21 and the stage 31 moves and the molding light EL is no longer applied to the molten pool MP, the molding material M melted in the molten pool MP is cooled and solidified (that is, solidified). . As a result, as shown in FIG. 3(c), a modeled object composed of the solidified modeling material M is deposited on the modeling surface MS.

The modeling apparatus SYS performs a series of operations including the formation of the molten pool MP by irradiation of the modeling light EL, the supply of the modeling material M to the molten pool MP, the melting of the supplied modeling material M, and the solidification of the molten modeling material M. 3, is repeated while moving the modeling head 21 along at least one of the X-axis direction and the Y-axis direction with respect to the modeling surface MS, as shown in FIG. 3(d). At this time, the modeling apparatus SYS irradiates a region on the modeling surface MS where the modeled object is desired to be modeled with the shaping light EL, but does not irradiate a region on the modeling surface MS where the modeled object is not desired to be modeled with the shaping light EL. In other words, the modeling apparatus SYS moves the target irradiation area EA along the predetermined movement locus on the modeling surface MS, and illuminates the modeling light EL at timing corresponding to the distribution of the area where the object is desired to be modeled. to irradiate. As a result, the molten pool MP also moves on the modeling surface MS along the movement locus corresponding to the movement locus of the target irradiation area EA. Specifically, the molten pool MP is sequentially formed in a portion irradiated with the shaping light EL in the area along the movement locus of the target irradiation area EA on the modeling surface MS. As a result, as shown in FIG. 3(e), a structural layer SL corresponding to a modeled object, which is an aggregate of the modeling material M solidified after being melted, is modeled on the modeling surface MS. In other words, the structural layer SL corresponds to an assembly of objects formed on the modeling surface MS in a pattern corresponding to the movement trajectory of the molten pool MP (that is, in plan view, the structure layer SL has a shape corresponding to the movement trajectory of the molten pool MP). A structural layer SL) having a shape is formed. Note that when the target irradiation area EA is set in an area where the object is not desired to be modeled, the modeling apparatus SYS irradiates the target irradiation area EA with the modeling light EL, and even if the supply of the modeling material M is stopped. good. Further, when the target irradiation area EA is set in an area in which the modeled object is not desired to be modeled, the modeling apparatus SYS supplies the modeling material M to the target irradiation area EA, The target irradiation area EA may be irradiated with EL.

The modeling apparatus SYS repeatedly performs operations for modeling such a structural layer SL based on the three-dimensional model data under the control of the control device 7 . Specifically, first, the control device 7 creates slice data by slicing the three-dimensional model data at a lamination pitch before performing an operation for forming the structural layer SL. The modeling apparatus SYS performs an operation for modeling the first structural layer SL#1 on the modeling surface MS corresponding to the surface of the work W based on the slice data corresponding to the structural layer SL#1. Specifically, the control device 7 controls the modeling unit 2 and the stage unit 3 to model the first structural layer SL#1 based on the slice data corresponding to the structural layer SL#1. Generate printing control information. The modeling control information may include, for example, modeling path information indicating a relative movement trajectory of the target irradiation area EA of the modeling light EL on the modeling surface MS with respect to the modeling surface MS. After that, the control device 7 controls the modeling unit 2 and the stage unit 3 to model the first structural layer SL#1 based on the modeling pass information. As a result, the structural layer SL#1 is modeled on the modeling surface MS as shown in FIG. 4(a). Incidentally, the modeling control information may be generated in advance before the modeling apparatus SYS starts the additional processing. In this case, instead of generating modeling control information, the control device 7 acquires modeling control information that has been generated in advance, and controls the modeling unit to model the structural layer SL based on the acquired modeling control information. 2 and the stage unit 3 may be controlled. After that, the modeling apparatus SYS sets the surface (that is, the upper surface) of the structure layer SL#1 as a new modeling surface MS, and then models the second structure layer SL#2 on the new modeling surface MS. do. In order to model the structural layer SL#2, the control device 7 first operates at least one of the head drive system 22 and the stage drive system 32 so that the modeling head 21 moves along the Z-axis with respect to the stage 31. Control. Specifically, the control device 7 controls at least one of the head drive system 22 and the stage drive system 32 to set the target irradiation area EA to the surface of the structure layer SL#1 (that is, the new modeling surface MS). The modeling head 21 is moved toward the +Z side and/or the stage 31 is moved toward the -Z side so that After that, under the control of the control device 7, the modeling apparatus SYS performs the same operation as that for modeling the structural layer SL#1, based on the slice data corresponding to the structural layer SL#2. , the structural layer SL#2 is formed. As a result, the structural layer SL#2 is formed as shown in FIG. 4(b). After that, the same operation is repeated until all structural layers SL constituting the three-dimensional structure ST to be modeled on the workpiece W are modeled. As a result, as shown in FIG. 4(c), a three-dimensional structure ST is formed by a laminated structure in which a plurality of structural layers SL are laminated.

(2-2) Additional Processing for Work W Having Holes in Outer Wall In the present embodiment, an object having holes in the outer wall may be used as the work W. FIG. In other words, under the control of the control device 7, the modeling apparatus SYS may perform the additional processing described above on the workpiece W having the hole formed in the outer wall. As an example, in the present embodiment, a hollow object having holes formed in its outer wall may be used as the workpiece W. That is, under the control of the control device 7, the modeling apparatus SYS may perform the additional processing described above on the hollow workpiece W having the hole formed in the outer wall. In this case, the modeling apparatus SYS may model an additional portion covering at least a portion of the work W as the three-dimensional structure ST.

Before the molding apparatus SYS performs additional processing on the workpiece W having the hole formed in the outer wall, the workpiece W may be provided with a lid member that closes the hole. After that, the lid member may be fixed to the work W. For example, the lid member may be fixed to the work W by being joined to the work W. The operation of joining the cover member to the work W is to fix the cover member, which was detachable from the work W before joining the cover member to the work W, to the work W so that the cover member cannot be easily removed from the work W. It may mean the action of Alternatively, the lid member may be fixed so as to be removable from the workpiece W. For example, or alternatively, the lid member may be fixed to the work W using a fixing pin or the like for fixing the lid member to the work W. Alternatively, the lid member may not be fixed to the workpiece W. After that, the modeling apparatus SYS performs additional processing on the workpiece W whose hole is closed by the cover member (that is, the workpiece W arranged so that the cover member joined or not joined to the workpiece W covers the hole). may be performed. For example, the modeling apparatus SYS may model an additional portion that covers at least part of at least one of the work W and the cover member as the three-dimensional structure ST.

An example of a workpiece W having a hole formed in its outer wall is an object to be repaired that has a hole that needs to be repaired (for example, an object that has a hole with a shape different from the original ideal shape). be done. In this case, the modeling apparatus SYS may restore the restoration target by performing additional processing on the restoration target after the cover member is arranged in the hole of the restoration target. For example, the modeling apparatus SYS may perform additional processing for modeling the additional portion on the restoration target so that the restoration target on which the additional portion is formed has a desired three-dimensional shape.

An example of a workpiece W having holes formed in its outer wall is an improvement object with holes that need to be improved (for example, an object with holes whose shape or size is desired to be changed). In this case, the modeling apparatus SYS may repair the improvement target by performing additional processing on the improvement target after the cover member is arranged in the hole of the improvement target. For example, the modeling apparatus SYS may perform additional processing to model the additional portion on the improvement object so that the three-dimensional shape of the improvement object on which the additional portion is modeled becomes a desired shape.

Another example of the work W having holes formed in the outer wall is a casting manufactured by casting (in other words, shaped). Specifically, as an example of the work W having a hole formed in the outer wall thereof, there is a hollow casting manufactured by casting using a core. However, the work W having holes formed in the outer wall is not limited to a casting manufactured by casting. Specifically, as long as holes are formed in the outer wall of an object that is different from a casting manufactured by casting, the object may be used as the work W having holes formed in the outer wall.

As an example of a hollow casting manufactured by casting using a core, a turbine blade TB as an intermediate product (hereinafter referred to as "blade part TB0") used to manufacture a turbine blade TB as a finished product is given. In this case, the modeling apparatus SYS may manufacture the turbine blade TB as a finished product by performing additional processing on the blade component TB0. That is, the modeling apparatus SYS may function as a manufacturing apparatus that manufactures a finished product by performing additional processing on an intermediate product (in other words, a semi-finished product). Specifically, the modeling apparatus SYS performs additional processing on the blade part TB0 to form an additional part (in other words, an additional object) OB as the three-dimensional structure ST on the blade part TB0. A turbine blade TB may be manufactured that is an object that includes OB and blade part TB0 (typically an object in which additional portion OB and blade part TB0 are integrated). Note that the turbine blade TB may be a moving blade or a stationary blade.

Hereinafter, as an example of the operation of performing additional machining on the workpiece W having the outer wall formed with the hole, the operation of manufacturing the turbine blade TB by performing the additional machining on the blade component TB0 (that is, the operation in which the hole is formed An operation of manufacturing a finished product by performing additional processing on an intermediate product) will be described.

An example of a finished turbine blade TB is shown in FIGS. 5(a) and 5(b). FIG. 5(a) is a perspective view showing an example of the turbine blade TB. FIG. 5(b) is a cross-sectional view showing an example of the turbine blade TB. Specifically, FIG. 5(b) is a cross-sectional view of the turbine blade TB shown in FIG. 5(a) taken along line V-V'. As shown in FIGS. 5(a) and 5(b), the turbine blade TB has an airfoil shape in plan view (in the example shown in FIG. 5(a), in plan view along the XY plane). is doing. The turbine blade TB has a hollow shape with a gap SP formed therein. It is not easy to manufacture the hollow turbine blade TB shown in FIGS. 5(a) and 5(b) by casting (particularly, the turbine blade TB in which the outer wall has no holes leading to the gap SP). This is because if a hole leading to the gap SP is not formed in the outer wall of the turbine blade TB, it is not easy to remove the core for forming the gap SP from the gap SP. Therefore, in the present embodiment, instead of directly manufacturing the turbine blade TB, which is a finished product, by casting, the blade component TB0, which is an intermediate product, is manufactured by casting, and then additional machining is performed on the blade component TB0. is performed, a turbine blade TB, which is a finished product, is manufactured.

An example of a blade part TB0 used to manufacture the turbine blade TB shown in FIGS. 5(a) and 5(b) is shown in FIGS. 6(a) and 6(b). FIG. 6(a) is a perspective view showing the blade component TB0. FIG. 6(b) is a cross-sectional view showing the blade component TB0. Specifically, FIG. 6(b) is a sectional view taken along line VI-VI' of the blade component TB0 shown in FIG. 6(a). As shown in FIGS. 6(a) and 6(b), the blade part TB0 is similar to the turbine blade TB in plan view (in the example shown in FIG. 6(a), in plan view along the XY plane) ) has an airfoil shape. The blade component TB0 has a hollow shape with a void SP0 formed therein, similar to the turbine blade TB. The air gap SP0 is used as the air gap SP for the turbine blades TB. The blade part TB0 in which such a gap SP0 is formed may be manufactured by casting using a core. Specifically, in order to manufacture the blade component TB0, a core formed by hardening powder such as sand is placed at a desired position inside the mold for manufacturing the blade component TB0 (specifically, is arranged at the position where the air gap SP0 is formed. A material such as molten metal is then poured into the mold. As a result, the blade component TB0 is manufactured in which the space in which the core is arranged is secured as the gap SP0.

A hole TH is formed in the outer wall OM of the blade part TB0. The hole TH is a through hole penetrating the outer wall OM. The hole TH is a through hole that connects the space SP0 and the space outside the blade part TB0. The cross-sectional shape of the hole TH (specifically, the cross-sectional shape along the surface of the outer wall OM) may be circular, polygonal, or any other shape. , the hole TH may be used as a removal port for removing the core from the void SP0 after the blade part TB0 is manufactured by casting. Therefore, after the blade component TB0 is manufactured by casting, the core filling the space SP0 may be removed from the space SP0 through the hole TH. However, the use of the hole TH is not limited to the use of removing the core.

The outer wall OM of the blade part TB0 includes, for example, side walls WM that constitute the upper and lower surfaces of the airfoil (that is, a pair of surfaces for generating so-called lift and a pair of surfaces for generating a pressure difference). good too. The outer wall OM may include a top wall CM that connects the ends of the side walls WM on the +Z side. The outer wall OM may include a bottom wall BM connecting the −Z side ends of the side walls WM. In the example shown in FIGS. 6(a) and 6(b), the hole TH is formed in the upper wall CM. However, the hole TH may be formed in a wall portion of the outer wall OM that is different from the upper wall CM. Also, in the example shown in FIGS. 6A and 6B, two holes TH are formed. However, a single hole TH may be formed, or three or more holes TH may be formed.

In order to manufacture the turbine blade TB from such a blade component TB0, first, the lid member LB is arranged in the hole TH. A blade part TB0 having a lid member LB arranged in the hole TH is shown in FIGS. 7(a) and 7(b). FIG. 7(a) is a perspective view showing the blade part TB0 in which the lid member LB is arranged in the hole TH. FIG. 7(b) is a cross-sectional view showing the blade component TB0 in which the lid member LB is arranged in the hole TH. Specifically, FIG. 7(b) is a VII-VII' sectional view of the blade part TB0 shown in FIG. 7(a). As shown in FIGS. 7A and 7B, the lid member LB is arranged on the blade part TB0 so that the lid member LB closes the hole TH. When a plurality of holes TH are formed in the blade part TB0, a plurality of lid members LB are arranged to cover the plurality of holes TH, respectively.

A state in which "the lid member LB blocks the hole TH" in the present embodiment may mean a state in which "at least part of the lid member LB is arranged inside the hole TH". The state in which “the lid member LB closes the hole TH” may mean the state in which “the hole TH is hidden by the lid member LB”. The state in which "the lid member LB closes the hole TH" may mean the state in which "the inflow of fluid into the space SP0 through the hole TH is suppressed by the lid member LB". The state in which "the lid member LB blocks the hole TH" means a state in which "the amount of fluid flowing into the space SP0 through the hole TH is reduced compared to the case where the lid member LB does not block the hole TH". You may have Moreover, the state in which "the lid member LB blocks the hole TH" may mean "the state in which the hole TH is partially blocked by the lid member LB". When the lid member LB is arranged on the blade part TB0 so as to realize these states, the lid member LB may be regarded as blocking the hole TH.

The lid member LB may have any structure as long as it can close the hole. An example of the lid member LB is shown in FIGS. 8(a) and 8(b). FIG. 8(a) is a perspective view showing an example of the lid member LB. FIG. 8B is a cross-sectional view showing an example of the lid member LB. Specifically, FIG. 8(b) is a cross-sectional view of the lid member LB taken along line VIII-VIII' of FIG. 8(a). As shown in FIGS. 8(a) and 8(b), the lid member LB may include an insertion portion LB1 and a protruding portion LB2. Note that the insertion portion LB1 may also be referred to as an insertion member. The protrusion LB2 may be referred to as a protrusion member.

As shown in FIG. 9 showing the lid member LB inserted into the hole TH, the insertion portion LB1 is a portion of the lid member LB that can be inserted into the hole TH. The entire insertion portion LB1 may be insertable into the hole TH. Alternatively, a portion of the insertion portion LB1 may be insertable into the hole TH, while the other portion of the insertion portion LB1 may not be insertable into the hole TH. Since the insertion portion LB1 is inserted into the hole TH, the size of the insertion portion LB1 is equal to or smaller than the size of the hole TH. Specifically, the cross direction (the direction along the XY plane in the example shown in FIG. 9) intersecting the insertion direction (the Z-axis direction in the example shown in FIG. 9) in which the insertion portion LB1 is inserted, and the blade component The size R1 of the insertion portion LB1 in the direction along the upper wall CM of TB0) is equal to or smaller than the size R3 of the hole TH in the cross direction. Further, the cross-sectional shape of the insertion portion LB1 including the axis along the cross direction is the same as the cross-sectional shape of the hole TH crossing the insertion direction. In the example shown in FIG. 8A, since the cross-sectional shape of the hole TH is circular, the cross-sectional shape of the insertion portion LB1 is also circular. However, the cross-sectional shape of the insertion portion LB1 may not be the same as the cross-sectional shape of the hole TH. Specifically, the insertion portion LB1 may have any shape as long as at least part of the insertion portion LB1 can be inserted into the hole TH.

The projecting portion LB2 is a portion of the lid member LB that is connected to the insertion portion LB1. For example, the protruding portion LB2 is a surface facing the hole TH of the insertion portion LB1 (in the examples shown in FIGS. 8A to 8B and 9A, the surface faces downward. , the surface facing the -Z side) (in the examples shown in FIGS. 8A to 8B and FIG. 9, the surface facing upward and the surface facing the +Z side) may be connected to The projecting portion LB2 may not be insertable into the hole TH. However, part of the projecting portion LB2 may be insertable into the hole TH. Since the protrusion LB2 may not be insertable into the hole TH, the size of the protrusion LB2 may be larger than the size of the hole TH. Specifically, the size R2 of the projecting portion LB2 in the cross direction (in the example shown in FIG. 9, the direction along the XY plane and the direction along the upper wall CM of the blade part TB0) is equal to the size R2 of the hole TH in the cross direction. may be larger than the size R3. Considering that the size R1 of the insertion portion LB1 is equal to or smaller than the size R3 of the hole TH as described above, the size R2 of the protrusion LB2 in the cross direction may be larger than the size R1 of the insertion portion LB1 in the cross direction. good. In this case, the protruding portion LB2 typically includes a first portion LB21 located directly above the insertion portion LB1 and a portion extending outward from the first portion LB21 (specifically, extending away from the first portion LB21). ) second portion LB22. In a state where the lid member LB is arranged on the blade part TB0 so as to block the hole TH, at least a part of the second part LB22 is located on the outer wall OM of the blade part TB0 (specifically, the upper part where the hole TH is formed). facing the wall CM (hereinafter the same in this paragraph). That is, the second portion LB22 includes a facing surface LB221 that can face the outer wall OM of the blade component TB0. Typically, when the lid member LB is arranged on the blade part TB0 so as to block the hole TH, at least part of the second part LB22 contacts the outer wall OM of the blade part TB0 via the opposing surface LB221. do. In this case, the lid member LB is substantially supported by the outer wall OM of the blade part TB0. More specifically, the lid member LB is supported by the outer wall OM of the blade part TB0 so that the lid member LB does not fall through the hole TH into the space SP0. Therefore, the projecting portion LB2 (especially the second portion LB22) may be regarded as functioning as a stopper for preventing the lid member LB from falling into the space SP0 through the hole TH.

The projecting portion LB2 may be connected to the inserting portion LB1 so as to be integrated with the inserting portion LB1. The projecting portion LB2 may be connected to the inserting portion LB1 so as to be fixed (for example, joined) to the inserting portion LB1. Alternatively, the projecting portion LB2 may be connected to the insertion portion LB1 so as to be separable from the insertion portion LB1. The projecting portion LB2 may be connected to the inserting portion LB1 so as to contact the inserting portion LB1 (but not be integrated with the inserting portion LB1 or fixed to the inserting portion LB1).

The material of the lid member LB may be the same as the material of the blade part TB0. Alternatively, the material of the lid member LB may be different from the material of the blade component TB0.

The lid member LB may be shaped by the shaping device SYS. Specifically, the modeling apparatus SYS performs additional processing on the modeling surface MS for modeling the lid member LB (for example, the surface of the workpiece W different from the blade part TB0), thereby creating a three-dimensional shape on the modeling surface MS. A lid member LB may be formed as the structure ST. More specifically, the modeling apparatus SYS irradiates the modeling surface MS with the modeling light EL from the irradiation optical system 211, and supplies the modeling material M from the material nozzle 212 to the irradiation position of the modeling light EL, A lid member LB may be modeled on the modeling surface MS.

The modeling apparatus SYS may model the lid member LB based on three-dimensional model data (hereinafter referred to as "lid model data") representing a lid model, which is a three-dimensional model of the lid member LB. The lid model data may be generated in advance. Also, the lid model data may be generated based on three-dimensional model data representing a blade model, which is a three-dimensional model of the blade part TB0. Alternatively, the modeling apparatus SYS (in particular, the control device 7) may generate lid model data. For example, the modeling apparatus SYS measures the three-dimensional shape of the blade part TB0 (particularly, the three-dimensional shape of the hole TH) using the measuring device 4, and a cover capable of closing the hole TH having the measured three-dimensional shape Lid model data representing a three-dimensional model of the member LB may be generated. For example, the modeling apparatus SYS may measure the three-dimensional shape of a sample of the lid member LB using the measuring device 4 and generate lid model data based on the measured three-dimensional shape. Alternatively, the modeling apparatus SYS corrects lid model data generated in advance based on the measurement results of the three-dimensional shape of the blade component TB0 (particularly, the three-dimensional shape of the hole TH) by the measuring device 4, and creates the modified lid model. The lid member LB may be shaped based on the data.

Alternatively, the lid member LB may be manufactured by a manufacturing apparatus different from the modeling apparatus SYS. For example, the lid member LB may be manufactured by a 3D printer (that is, a processing device that performs additional processing) different from the modeling device SYS. For example, the lid member LB may be manufactured by a processing apparatus that performs removal processing using a tool or an energy beam (for example, light). For example, the lid member LB may be manufactured by casting or forging.

After the lid member LB is arranged on the blade part TB0, the lid member LB is fixed to the blade part TB0. The lid member LB may be fixed to the blade component TB0 by the modeling apparatus SYS. For example, the modeling apparatus SYS may fix the lid member LB to the blade component TB0 by joining the lid member LB to the blade component TB0. Specifically, as shown in FIG. 10 conceptually showing the modeling apparatus SYS that joins the lid member LB to the blade part TB0, the modeling apparatus SYS irradiates at least part of the lid member LB with the shaping light EL. , the lid member LB may be joined to the blade component TB0. More specifically, the modeling apparatus SYS may irradiate at least part of the lid member LB with the shaping light EL to melt at least part of the lid member LB using the shaping light EL. As an example, the modeling apparatus SYS irradiates at least part of the portion of the lid member LB facing the outer wall OM of the blade part TB0 (for example, the second portion LB22 of the projecting portion LB2 described above) with the modeling light EL. Then, the portion of the lid member LB facing the outer wall OM of the blade part TB0 may be melted. As a result, at least part of the melted lid member LB is solidified, thereby joining the lid member LB to the blade component TB0. That is, the modeling apparatus SYS may join the lid member LB to the blade component TB0 by performing welding using the modeling light EL.

The modeling apparatus SYS does not need to supply the modeling material M from the material nozzle 212 during the period in which the modeling light EL is emitted to join the lid member LB to the blade part TB0. In other words, the modeling apparatus SYS irradiates at least a part of the lid member LB with the shaping light EL from the irradiation optical system 211 without supplying the molding material M from the material nozzle 212, so that the blade part TB0 and the lid member LB may be joined (that is, welded). As a result, the modeling device SYS that performs so-called additional processing can appropriately function as a joining device (for example, a welding device) for joining the lid member LB to the blade part TB0. The modeling apparatus SYS supplies the modeling material M from the material nozzle 212 during the period in which the modeling light EL is emitted to join the lid member LB to the blade part TB0, and the blade part TB0 and the lid member LB may be overlay welded.

The modeling apparatus SYS forms a cover member based on three-dimensional model data (hereinafter referred to as “intermediate product model data”) representing an intermediate product model, which is a three-dimensional model of the blade part TB0 after the cover member LB is arranged. LB may be joined to blade part TB0. Incidentally, when the lid member LB is joined to the blade part TB0, the intermediate product model data may indicate a three-dimensional model of the blade part TB0 after the lid member LB is joined. Specifically, the modeling apparatus SYS identifies the position where the lid member LB is arranged (or the position where the lid member LB is to be joined) based on the intermediate product model data, and applies the molding light EL to the identified position. , the lid member LB may be joined to the blade component TB0.

The intermediate product model data may be generated in advance. Alternatively, the modeling apparatus SYS (in particular, the control device 7) may generate the intermediate product model data. For example, the modeling apparatus SYS uses the measuring device 4 to measure the three-dimensional shape of the blade part TB0 on which the lid member LB is arranged (in particular, the three-dimensional shape of the blade part TB0 including the arranged lid member LB). , the intermediate product model data may be generated based on the measurement result of the three-dimensional shape of the blade component TB0 by the measuring device 4 .

Alternatively, the lid member LB may be joined to the blade part TB0 using a device (for example, a welding device) different from the modeling device SYS. Alternatively, the lid member LB may not be joined to the blade component TB0. For example, when the lid member LB is arranged on the blade part TB0 and the frictional force between the lid member LB and the blade part TB0 is relatively large, the lid member LB is not joined to the blade part TB0. Even if it does, the possibility that the lid member LB will come off from the blade part TB0 is not high. That is, even if the lid member LB is not joined to the blade component TB0, it may be considered that the lid member LB is substantially fixed to the blade component TB0. In this case, the lid member LB may not be joined to the blade component TB0. Alternatively, the lid member LB may not be fixed to the blade component TB0 in the first place.

After that, the modeling apparatus SYS manufactures the turbine blade TB by performing additional processing on the blade component TB0 to which the lid member LB is fixed (for example, joined). Specifically, as shown in FIG. 11A, which is a cross-sectional view showing the blade part TB0 to which the additional processing has been performed, the modeling apparatus SYS performs additional processing on the blade part TB0 to obtain a three-dimensional shape. An additional portion (in other words, an additional object) OB as the structure ST is shaped into the blade part TB0. The additional portion OB is a modeled object corresponding to the difference between an intermediate product, the blade component TB0 on which the lid member LB is arranged, and a finished product, the turbine blade TB. In other words, the blade part TB0 on which the lid member LB is arranged, an object including the intermediate part and the additional part OB, corresponds to the finished product, the turbine blade TB.

As shown in FIG. 11(a), the additional portion OB may cover at least a portion of at least one of the blade component TB0 and the lid member LB. In order to shape such an additional portion OB, the shaping apparatus SYS irradiates at least a portion of at least one of the blade part TB0 and the lid member LB with the shaping light EL from the irradiation optical system 211, and the material nozzle 212 , the modeling material M is supplied to the irradiation position of the modeling light EL. For example, when at least part of the additional portion OB to be modeled by the modeling apparatus SYS covers at least part of the blade part TB0, the modeling apparatus SYS irradiates at least part of the blade part TB0 with the modeling light EL. In addition, the modeling material M may be supplied to the irradiation position of the modeling light EL. For example, when at least part of the additional portion OB to be modeled by the modeling apparatus SYS covers at least part of the lid member LB, the modeling apparatus SYS irradiates at least part of the lid member LB with the modeling light EL. In addition, the modeling material M may be supplied to the irradiation position of the modeling light EL.

The modeling apparatus SYS may model a part of the modeled object that serves as the base of the additional portion OB, and then model the additional portion OB on the modeled object that serves as the base. For example, as shown in FIG. 11B, which is a cross-sectional view showing the blade part TB0 on which the additional processing has been performed, the modeling apparatus SYS places a A modeled object that serves as the base of the additional portion OB (hereinafter referred to as “base portion BB”) may be modeled. The base portion BB may cover at least a portion of at least one of the blade component TB0 and the lid member LB. After that, the modeling apparatus SYS may model the additional portion OB on at least part of the base portion BB. The additional portion OB may cover at least part of the base portion BB.

The modeling apparatus SYS may model the base portion BB whose upper surface (in the example shown in FIG. 11(b), the surface facing the +Z side) is flat. In this case, the lower surface of the additional portion OB facing the upper surface of the base portion BB (in the example shown in FIG. 11B, the surface facing the -Z side) may also be flat. That is, the modeling apparatus SYS may model the additional portion OB having a flat bottom surface on the base portion BB having a flat top surface. In this case, since the additional portion OB is modeled on the flat modeling surface MS, the additional portion OB is modeled on the non-planar modeling surface MS (for example, the modeling surface MS that has unevenness or is curved). The modeling apparatus SYS becomes easier to model the additional portion OB as compared with the case.

It should be noted that the modeled object that serves as the base of the additional portion OB (for example, the base portion BB shown in FIG. 11(b)) may constitute a part of the additional portion OB. In this case, the modeling apparatus SYS may model the additional portion OB by modeling a part of the additional portion OB and then modeling the other portion of the additional portion OB. .

Because the shaping apparatus SYS shapes at least a portion of the additional portion OB on at least a portion of the lid member LB, there is a possibility that at least a portion of the lid member LB will melt when shaping the additional portion OB. In this case, the thickness of the lid member LB (for example, thickness Sz, which is the size in the Z-axis direction in FIG. The thickness may be set to such an extent that a hole penetrating through the member LB is not formed. Similarly, even when the shape of the lid member LB is different from the shape shown in FIG. 11A, the thickness of the lid member LB is , the thickness may be set to such an extent that a hole penetrating through the lid member LB is not formed. Even when the lid member LB has a flat plate shape, the thickness of the lid member LB (that is, the thickness of the plate) is the same as that of the lid member LB even if at least part of the lid member LB is melted when the additional portion OB is formed. The thickness may be set to such an extent that a hole penetrating through the member LB is not formed.

The modeling apparatus SYS may model the additional part OB based on three-dimensional model data (hereinafter referred to as "modeling model data") representing a modeling model that is a three-dimensional model of the additional part OB. The modeling model data may be generated in advance. Alternatively, the modeling apparatus SYS (in particular, the control device 7) may generate the modeling model data. For example, the modeling apparatus SYS uses the measuring device 4 to measure the three-dimensional shape of the blade part TB0 on which the lid member LB is arranged (in particular, the three-dimensional shape of the blade part TB0 including the arranged lid member LB). , a modeling model showing a three-dimensional model of the additional portion OB corresponding to the difference between the blade component TB0 on which the lid member LB is arranged and the turbine blade TB, based on the measurement result of the three-dimensional shape of the blade component TB0 by the measuring device 4; data may be generated. More specifically, the modeling apparatus SYS generates the above-described intermediate product model data based on the measurement result of the three-dimensional shape of the blade part TB0 by the measuring device 4, and the intermediate product model data and the turbine blade as the finished product. By calculating the difference from the three-dimensional model data representing the three-dimensional model of the TB (hereinafter referred to as "finished product model data"), the modeling model data representing the three-dimensional model of the additional portion OB may be generated. .

As described above, in this embodiment, the additional portion OB is shaped into the blade part TB0 on which the lid member LB is arranged. Therefore, the modeling model data generated in advance usually indicates a three-dimensional model of the additional portion OB corresponding to the difference between the blade component TB0 on which the lid member LB is arranged and the turbine blade TB. On the other hand, depending on the case, the molding model data generated in advance may indicate a three-dimensional model of the molding corresponding to the difference between the blade part TB0 in which the lid member LB is not arranged and the turbine blade TB. There is In this case, the modeling apparatus SYS (particularly, the control device 7) corrects the modeling model data generated in advance so that the difference between the blade part TB0 on which the lid member LB is arranged and the turbine blade TB is corrected. Modeling model data representing a three-dimensional model of the corresponding modeled object may be generated. In other words, the modeling apparatus SYS (particularly, the control device 7) creates a new model actually used to model the additional portion OB based on the modeling model data generated in advance (that is, the modeling model data before correction). modeling model data (that is, modeling model data after correction) may be generated. The modeling model data before correction corresponds to model data representing a three-dimensional model of the modeling object corresponding to the difference between the blade component TB0 on which the lid member LB is not arranged and the turbine blade TB. On the other hand, the modeled model data after correction corresponds to model data representing a three-dimensional model of a modeled object corresponding to the difference between the blade component TB0 on which the lid member LB is arranged and the turbine blade TB.

As an example, the modeling apparatus SYS may generate post-correction modeling model data based on pre-correction modeling model data and lid model data representing a lid model that is a three-dimensional model of the lid member LB. Specifically, as shown in FIG. 12, the modeling apparatus SYS generates post-correction modeling model data by removing the model portion corresponding to the lid model from the modeling model indicated by the pre-correction modeling model data. may

As another example, the modeling apparatus SYS, based on the modeling model data before correction and the intermediate product model data indicating the intermediate product model that is the three-dimensional model of the blade part TB0 after the lid member LB is arranged, Corrected modeling model data may be generated. Specifically, the modeling apparatus SYS removes the model portion corresponding to the intermediate product model (particularly, the model portion corresponding to the lid model) from the modeling model indicated by the modeling model data before correction. You may generate model data. The intermediate product model data used to generate the corrected modeling model data may be intermediate product model data generated in advance. Alternatively, the intermediate product model data used to generate the corrected modeling model data may be the intermediate product model data generated by the modeling apparatus SYS. For example, the modeling apparatus SYS uses the measuring device 4 to measure the three-dimensional shape of the blade part TB0 on which the lid member LB is arranged (in particular, the three-dimensional shape of the blade part TB0 including the arranged lid member LB). Alternatively, intermediate product model data may be generated based on the measurement result of the three-dimensional shape of the blade component TB0 by the measuring device 4, and corrected molding model data may be generated based on the generated intermediate product model data.

(3) Technical Effect of Modeling Apparatus SYS As described above, the modeling apparatus SYS of the present embodiment can manufacture a turbine blade TB using the blade component TB0 in which the hole TH is formed in the outer wall OM. . In particular, the shaping apparatus SYS can manufacture the turbine blade TB by covering the hole TH with the lid member LB and shaping the additional portion OB integrated with the blade component TB0 in the blade component TB0. Therefore, the modeling apparatus SYS can appropriately manufacture the turbine blade TB in which the hole TH is not exposed to the outside from the blade component TB0 in which the hole TH is formed in the outer wall OM. As an example, the modeling apparatus SYS appropriately manufactures a hollow turbine blade TB in which the hole TH for removing the core used for casting is not exposed to the outside from the hollow blade part TB0 manufactured by casting. can be done.

Further, the modeling apparatus SYS can join the lid member LB to the blade part TB. For this reason, a series of processes including the process of joining the lid member LB to the blade component TB and the process of manufacturing the turbine blade TB by performing additional processing on the blade component TB0 are performed by a single device, the modeling apparatus SYS. will be Therefore, it is possible to reduce the manufacturing cost of the turbine blade TB compared to the case where a device for joining the lid member LB to the blade component TB is required separately from the modeling device SYS.

Also, the modeling apparatus SYS can manufacture the lid member LB. Therefore, a series of processes including the process of manufacturing the lid member LB and the process of manufacturing the turbine blade TB by performing additional processing on the blade component TB0 are performed by a single apparatus, the modeling apparatus SYS. Therefore, it is possible to reduce the manufacturing cost of the turbine blade TB compared to the case where a device for manufacturing the lid member LB is required separately from the modeling device SYS.

(4) Modification Next, a modification of the modeling apparatus SYS will be described. In addition, the same reference numerals are assigned to the components that have already been described, and detailed description thereof will be omitted.

(4-1) First Modification In the above description, the thickness of the projecting portion LB2 of the lid member LB is constant. The "thickness of the protruding portion LB2" referred to here is the insertion direction in which the insertion portion LB1 is inserted into the hole TH (in the example shown in FIGS. 8A and 8B, the Z-axis direction ) may mean the size of the protrusion LB2. The insertion direction may be considered equivalent to the direction intersecting with the outer wall OM (specifically, the upper wall CM in which the hole TH is formed, hereinafter the same in the first modification) of the blade part TB0. On the other hand, in the first modified example, the thickness of the projecting portion LB2 of the lid member LB may not be constant. An example of the lid member LB in the first modified example in which the thickness of the projecting portion LB2 is not constant will be described below with reference to FIGS. 13 to 21 . In the following description, the lid member LB in the first modified example will be referred to as "lid member LB-a".

(4-1-1) First Lid Member LB-a in First Modification
First, the first lid member LB-a in the first modified example will be described with reference to FIGS. 13 and 14. FIG. In the following description, the first lid member LB-a will be referred to as "lid member LB-a1". FIG. 13 is a sectional view showing the lid member LB-a1. FIG. 14 is a sectional view showing the lid member LB-a1 inserted into the hole TH.

As shown in FIGS. 13 and 14, the lid member LB-a1 has a constant thickness in comparison with the lid member LB shown in FIGS. However, it differs in that it includes a protruding portion LB2-a1 whose thickness does not have to be constant. Other features of the lid member LB-a1 may be the same as other features of the lid member LB shown in FIGS. 8(a) and 8(b) described above. Projection LB2-a1 differs from projection LB2 in that it includes projection LB22-a1 that does not have to have a constant thickness instead of second portion LB22 that has a constant thickness. different. Other features of the protrusion LB2-a1 may be the same as other features of the protrusion LB2 described above.

The thickness of the second portion LBLB22-a1 is the cross direction crossing the insertion direction in which the insertion portion LB1 is inserted into the hole TH. , such as the Y-axis direction) (that is, the distance from the first portion LB21 located directly above the insertion portion LB1). As described above, the insertion direction in which the insertion portion LB1 is inserted into the hole TH is the direction that intersects the outer wall OM of the blade part TB0. may be considered equivalent to the direction intersecting the Since the insertion portion LB1 is inserted into the hole TH when the lid member LB-a1 is arranged on the blade part TB0, the thickness of the second portion LB22-a1 changes according to the distance from the hole TH in the cross direction. You may

Specifically, as shown in FIG. 13, in the lid member LB-a1, the protruding portion LB2-a1 (especially, the second portion The thickness T1 of the LB22-a1) is the protruding portion LB2-a1 (particularly, the second portion LB22-a1 ), the thickness of the protruding portion LB2-a1 (particularly, the second portion LB22-a1) may vary. In the example shown in FIGS. 13 and 14, the thickness of the protruding portion LB2-a1 (especially the second portion LB22-a1) at a certain position becomes smaller as the position moves away from the insertion portion LB1 (hole TH) in the cross direction. . In particular, in the examples shown in FIGS. 13 and 14, the thickness of the protruding portion LB2-a1 (especially the second portion LB22-a1) at a certain position increases as the position moves away from the insertion portion LB1 (hole TH) in the cross direction. decrease continuously. That is, the projecting portion LB2-a1 (especially the second portion LB22-a1) may have a so-called tapered shape.

In this case, typically, the facing surface LB221 of the second portion LB22-a1 that can face the outer wall OM of the blade part TB0 and the second portion LB22-a1 that does not face the outer wall OM of the blade part TB0 It does not have to be parallel to the non-facing surface LB222 (that is, facing away from the facing surface LB221). Specifically, the facing surface LB221 may be parallel to the XY plane including the axis extending along the cross direction, while the non-facing surface LB222 may not be parallel to the XY plane. In other words, the opposing surface LB221 is parallel to the surface of the outer wall OM of the blade component TB0 (specifically, the upper wall CM in which the hole TH is formed), while the non-facing surface LB222 is parallel to the surface of the blade component TB0. It does not have to be parallel to the surface of the outer wall OM (specifically, the upper wall CM in which the hole TH is formed).

When such a lid member LB-a1 is arranged on the blade component TB0, as shown in FIG. 14, the modeling apparatus SYS (or the lid member Another device for joining the LB-a1 to the blade part TB0) may irradiate the relatively thin portion of the protruding portion LB2-a1 with the shaping light EL or the like. As a result, part of the projecting portion LB2-a1 melts more easily than when a relatively thick portion of the projecting portion LB2-a1 is irradiated with the shaping light EL. As a result, the lid member LB-a1 is properly joined to the blade component TB0. Further, the strength of the lid member LB-a1 (in particular, the strength of the protrusion LB2-a1) is ensured by the relatively thick portion of the protrusion LB2-a1. As a result, the lid member LB-a1 (particularly, the protrusion LB2-a1) is broken, and as a result, the lid member LB-a1 falls into the hole TH (resulting in the lid member LB-a1 falling into the hole TH). It is unlikely that the hole TH will be blocked). In this way, the lid member LB-a1 has sufficient strength to allow the lid member LB-a1 to properly close the hole TH while making it relatively easy to join the lid member LB-a1 to the blade component TB0. It is possible to enjoy the technical effect of ensuring.

(4-1-2) Second Lid Member LB-a in First Modification
Next, the second lid member LB-a in the first modified example will be described with reference to FIG. In the following description, the second lid member LB-a will be referred to as "lid member LB-a2". FIG. 15 is a cross-sectional view showing the lid member LB-a2.

As shown in FIG. 15, the lid member LB-a2 has a projecting portion LB2-a1 (second portion LB22-a1 ) is replaced with a protrusion LB2-a2 (second portion LB22-a2) whose thickness changes stepwise. In this case, typically, the non-facing surface LB222 of the second portion LB22-a2 that does not face the outer wall OM of the blade part TB0 (that is, faces the opposite side to the facing surface LB221) is a surface having a step. It may be Other features of the lid member LB-a2 may be the same as other features of the lid member LB-a1 described above.

Such a lid member LB-a2 can also enjoy the same effects as the above-described lid member LB-a1 can enjoy.

(4-1-3) Third Lid Member LB-a in First Modification
Next, the third lid member LB-a in the first modified example will be described with reference to FIGS. 16 and 17. FIG. In the following description, the third lid member LB-a will be referred to as "lid member LB-a3". FIG. 16 is a sectional view showing the lid member LB-a3. FIG. 17 is a sectional view showing the lid member LB-a3 inserted into the hole TH.

As shown in FIGS. 16 and 17, the lid member LB-a3 is different from the lid member LB-a1 shown in FIGS. , in that it includes a protrusion LB2-a3 (second portion LB22-a3). Other features of the lid member LB-a3 may be the same as other features of the lid member LB-a1 described above.

In the second portion LB22-a3, while the opposing surface LB221 does not have to be parallel to the XY plane, the non-opposing surface LB222 is parallel to the XY plane. 13 and 14 in which the non-facing surface LB222 does not have to be parallel to the XY plane. That is, the second portion LB22-a3 does not have to have the opposing surface LB221 parallel to the surface of the outer wall OM of the blade part TB0 (specifically, the upper wall CM in which the hole TH is formed), 13 and 14 in that the facing surface LB222 is parallel to the surface of the outer wall OM of the blade part TB0 (specifically, the upper wall CM in which the hole TH is formed). is different from Other features of the protrusion LB2-a3 (second portion LB22-a3) may be the same as other features of the protrusion LB2-a1 (second portion LB22-a1) described above.

When such a lid member LB-a3 is arranged on the blade part TB0, similarly to the case where the lid member LB-a1 is arranged on the blade part TB0, the modeling apparatus SYS (or the lid member LB-a3 is Another device for bonding to the blade component TB0) may irradiate the relatively thin portion of the protruding portion LB2-a3 with the shaping light EL or the like. Here, when the lid member LB-a3 is arranged on the blade component TB0, as shown in FIG. 17, there may be a gap between the lid member LB-a3 and the blade component TB0. However, since at least part of the projecting portion LB2-a3 (especially the second portion LB22-a3) is melted by the irradiation of the shaping light EL, as shown in FIG. The second portion LB22-a3) hangs down toward the blade part TB0. As a result, the gap between the lid member LB-a3 and the blade part TB0 is eliminated or reduced. Therefore, the lid member LB-a3 is properly joined to the blade component TB0. Therefore, the lid member LB-a3 can also enjoy the same effects as the lid member LB-a1 described above.

Incidentally, as shown in FIG. 19, the molding device SYS (or another device for joining the lid member LB-a3 to the blade part TB0), in order to join the lid member LB-a3 to the blade part TB0, A gap between the lid member LB-a3 and the blade part TB0 may be irradiated with the shaping light EL or the like. Specifically, the modeling apparatus SYS uses the head drive system 22 and/or the stage drive system 32 to determine the positional relationship between the modeling head 21 and the blade component TB0 (that is, the workpiece W). The positional relationship may be changed so that the shaping light EL can be applied to the gap between the LB-a3 and the blade part TB0. After that, the modeling apparatus SYS may irradiate the gap between the lid member LB-a3 and the blade part TB0 with the modeling light EL. In this case, not only at least a portion of the lid member LB-a3 but also at least a portion of the blade part TB0 (in particular, its outer wall OM) is irradiated with the shaping light EL. Therefore, not only at least part of the lid member LB-a3 but also at least part of the blade part TB0 (in particular, its outer wall OM) is likely to melt. As a result, the lid member LB-a3 is firmly joined to the blade component TB0.

Also in the lid member LB-a3, similarly to the lid member LB-a2 shown in FIG. 15, the thickness of the protruding portion LB2-a3 (second portion LB22-a3) may change stepwise. Typically, the facing surface LB221 of the second portion LB22-a3 facing the outer wall OM of the blade part TB0 may be a surface having a step.

(4-1-4) Fourth Lid Member LB-a in First Modification
First, the fourth lid member LB-a in the first modification will be described with reference to FIGS. 20 and 21. FIG. In the following description, the fourth lid member LB-a is referred to as "lid member LB-a4". FIG. 20 is a cross-sectional view showing the lid member LB-a4. FIG. 21 is a sectional view showing the lid member LB-a4 inserted into the hole TH.

As shown in FIGS. 20 and 21, the lid member LB-a4 is different from the lid member LB-a1 shown in FIGS. It differs in that it includes an insertion portion LB1-a4 that does not have to be constant. That is, the lid member LB-a4 differs from the lid member LB-a1 shown in FIGS. 13 and 14 in that it includes an insertion portion LB1-a4 having a tapered shape. In this case, the lid member LB-a4 may have a tapered shape as a whole. That is, the lid member LB-a4 may include a conical member. When the lid member LB-a4 includes a member having a conical shape, the insertion portion LB1-a4 may be a portion of the lid member LB-a4 that includes the conical apex P (see FIG. 20). . On the other hand, the projecting portion LB2-a4 is a portion including the outer edge OE (see FIG. 20) of the conical bottom surface (the surface facing +Z side in the example shown in FIG. 20) of the lid member LB-a4. may Other features of the lid member LB-a4 may be the same as other features of the lid member LB-a1. The conical shape may be conical or pyramidal. Further, the shape of the lid member LB-a4 may be a truncated cone shape or a truncated pyramid shape. That is, the cone shape may be a truncated cone shape or a truncated pyramid shape.

Such a lid member LB-a4 can also enjoy the same effects as the above-described lid member LB-a1 can enjoy. In addition, since the insertion portion LB1-a4 of the lid member LB-a4 has a tapered shape, the size of the hole TH in the direction along the XY plane (that is, the cross direction) (for example, the diameter of the hole TH ) is changed, the insertion portion LB1-a4 can still be inserted into the hole TH. Conversely, when the above-described lid member LB-a1 in which the insertion portion LB1 does not have a tapered shape is used, the size of the hole TH in the direction along the XY plane (that is, the cross direction) (for example, the hole TH diameter) is changed, there is a possibility that the insertion portion LB1 cannot be inserted into the hole TH. Therefore, the lid member LB-a4 can enjoy the technical effect of relatively increasing the chances of appropriately functioning as the lid member LB that closes the hole TH.

The inner side surface IWS (see FIG. 21) of the blade part TB0 facing the hole TH may have a tapered shape. That is, a blade part TB0 having a tapered cross-sectional shape of the hole TH may be used. In this case, the blade component TB0 in which the cross-sectional shape of the hole TH is tapered may be manufactured by the above-described casting or the like. Alternatively, the blade part TB0 in which the cross-sectional shape of the hole TH is not tapered (for example, the blade part TB0 whose inner surface IWS is parallel to the Z-axis and which is shown in FIG. 21) is manufactured by the above-described casting or the like. After that, the modeling device SYS (or other device) processes (for example, removes or adds to) the inner surface IWS of the blade part TB0 facing the hole TH so that the cross-sectional shape of the hole TH is tapered. processing).

(4-2) Second Modification In the above description, the lid member LB can face the outer wall OM of the blade part TB0 and functions as a stopper for preventing the lid member LB from falling into the space SP0 through the hole TH. A lid member LB is used which includes a possible protrusion LB2. On the other hand, in the second modification, a lid member LB that does not include the projecting portion LB2 may be used. An example of the lid member LB in the second modification that does not include the projecting portion LB2 will be described below with reference to FIGS. 22 to 23. FIG. In the following description, the lid member LB in the second modified example will be referred to as "lid member LB-b". FIG. 22 is a cross-sectional view showing the lid member LB-b. FIG. 23 is a cross-sectional view showing the lid member LB-b inserted into the hole TH.

As shown in FIGS. 22 and 23, the lid member LBb includes an insertion portion LB3-b. The insertion portion LB3-b differs from the insertion portion LB1 shown in FIGS. 8A and 8B in that it does not have to be connected to the projecting portion LB2. Other features of the insertion portion LB3-b may be the same as other features of the insertion portion LB1 shown in FIGS. 8(a) and 8(b) described above.

In the second modified example, the insertion portion LB3-b has elastic force. In this case, of the insertion portion LB3-b inserted into the hole TH, the outer surface LB31-b facing the inner surface IWS of the blade part TB0 facing the hole TH is bladed by the elastic force of the insertion portion LB3-b. It may be pressed against the inner surface IWS of part TB0. As a result, the insertion portion LB3-b (that is, the lid member LB-b) may be fixed to the blade component TB0 by elastic force.

Since the lid member LB-b is fixed to the blade component TB0 by the elastic force of the lid member LB-b, the lid member LB-b does not necessarily have to be joined to the blade component TB0. However, the lid member LB-b may be joined to the blade component TB0. When the lid member LB-b is joined to the blade component TB0, a gap exposed to the outside is formed between the outer surface LB31-b of the insertion portion LB3-b and the inner surface IWS of the blade component TB0. A notch LB32-b may be formed in the insertion portion LB3-b. In this case, in order to join the lid member LB-b to the blade part TB0, the modeling apparatus SYS uses the notch LB32-b to separate the outer surface LB31-b of the insertion section LB3-b and the inner surface IWS of the blade part TB0. The void formed between them may be irradiated with the shaping light EL. As a result, not only at least part of the lid member LB-b (insertion portion LB3-b) but also at least part of the blade part TB0 (in particular, its outer wall OM) is irradiated with the shaping light EL. Therefore, not only at least part of the lid member LB-b (insertion portion LB3-b) but also at least part of the blade part TB0 (in particular, its outer wall OM) is likely to melt. As a result, the lid member LB-b is firmly joined to the blade component TB0.

It should be noted that, in the second modified example as well, constituent requirements specific to the first modified example may be employed. The structural requirements specific to the first modification may include, for example, a structural requirement that the thickness of the projecting portion LB2 of the lid member LB does not have to be constant.

(4-3) Third Modification In the above description, when a plurality of holes TH are formed in the blade part TB0, the blade part TB0 has a plurality of cover members LB for closing the plurality of holes TH. placed. On the other hand, in the third modification, when a plurality of holes TH are formed in the blade part TB0, the blade part TB0 has a cover member LB that collectively blocks at least two of the plurality of holes TH. may be placed. An example of the lid member LB in the third modification that collectively closes at least two holes TH will be described below with reference to FIGS. 24 to 25 . In the following description, the lid member LB in the third modified example will be referred to as "lid member LB-c". FIG. 24 is a cross-sectional view showing the lid member LB-c. FIG. 25 is a cross-sectional view showing the lid member LB-c inserted into the hole TH.

As shown in FIGS. 24 and 25, the lid member LB-c is different from the lid member LB shown in FIGS. It differs in that it contains two inserts LB1. Furthermore, the lid member LB-c includes a protrusion LB2-c instead of the protrusion LB2, compared to the lid member LB shown in FIGS. 8(a) and 8(b). different in The projection LB2-c differs from the projection LB2 in that it connects at least two insertion portions LB1. That is, at least two insertion portions LB1 are integrated via the protruding portion LB2-c. Other features of the lid member LB-c may be the same as other features of the lid member LB shown in FIGS. 8(a) and 8(b) described above.

Such a lid member LB-c can also enjoy the same effects as the above-described lid member LB can enjoy. In addition, since a single lid member LB-c can cover at least two holes TH, compared with the case where at least two lid members LB-c cover at least two holes TH, The number of lid members LB arranged on the blade part TB0 is reduced.

Also in the third modified example, constituent requirements specific to at least one of the first and second modified examples may be adopted. The structural requirements specific to the second modification may include, for example, a structural requirement that the lid member LB does not have to include the projecting portion LB2.

(4-4) Fourth Modification Next, a lid member LB in a fourth modification will be described with reference to FIGS. 26 and 27. FIG. In the following description, the lid member LB in the fourth modified example will be referred to as "lid member LB-d". FIG. 26 is a cross-sectional view showing the lid member LB-d. FIG. 27 is a cross-sectional view showing the lid member LB-d inserted into the hole TH.

As shown in FIGS. 26 and 27, the lid member LB-d is different from the lid member LB shown in FIGS. , in that it includes an insertion portion LB1-d and a projection portion LB2-d. Other features of the lid member LB-d may be the same as other features of the lid member LB shown in FIGS. 8(a) and 8(b) described above.

The insertion portion LB1-d differs from the insertion portion LB1 shown in FIGS. 8(a) and 8(b) in that its shape is different. Specifically, in the insertion portion LB1-d, the outer surface LB10-d of the insertion portion LB1-d facing the inner surface IWS of the blade part TB0 facing the hole TH should not be parallel to the inner surface IWS. It differs from the insertion portion LB1 in that it may include an outer surface parallel to the inner surface IWS. Other features of the insertion portion LB1-d may be the same as other features of the insertion portion LB1 shown in FIGS. 8(a) and 8(b) described above.

Specifically, the outer surface LB10-d may include an outer surface LB11-d and an outer surface LB12-d. However, the outer surface LB10-d does not have to include either one of the outer surfaces LB11-d and LB12-d.

The outer surface LB11-d may extend downward (toward the -Z side in the examples shown in FIGS. 26 and 27) from the projecting portion LB2-d. The outer surface LB11-d need not be parallel to the inner surface IWS. Since the inner surface IWS is normally parallel to the Z-axis, the outer surface LB11-d may be inclined with respect to the Z-axis. Incidentally, the inclination angle of the outer side surface LB11-d with respect to the Z axis may be any angle. As an example, the inclination angle of the outer surface LB11-d with respect to the Z axis may be 15 degrees. The outer surface LB11-d may widen outward from the projecting portion LB2-d downward. In other words, the insertion portion LB1-d may have a tapered shape that widens outward from the protruding portion LB2-d at a position including the outer side surface LB11-d. In other words, the insertion portion LB1-d increases in size along the direction along the XY plane (that is, the cross direction described above) downward from the protruding portion LB2-d at a position including the outer side surface LB11-d. It may have a tapered shape.

When the outer surface LB10-d includes such an outer surface LB11-d, blade part TB0 does not have a lid as compared to when the outer surface LB10-d is parallel to the inner surface IWS of blade part TB0. This reduces the possibility of interference between the blade part TB0 and the lid member LB-d when arranging the member LB-d. Therefore, the lid member LB-d can be smoothly arranged on the blade component TB0.

As shown in FIG. 27, if the outer surface LB11-d is not parallel to the inner surface IWS, a gap may be formed between the outer surface LB11-d and the inner surface IWS. The size (eg, volume) of the gap formed between the outer surface LB11-d and the inner surface IWS may be small. For example, the size of the gap formed between the outer surface LB11-d and the inner surface IWS may be smaller than the size of the gap formed between the outer surface LB12-d and the inner surface IWS.

On the other hand, the outer surface LB12-d may extend downward (toward the -Z side in the examples shown in FIGS. 26 and 27) from the outer surface LB11-d. Outer surface LB12-d may not be parallel to inner surface IWS. Since the inner surface IWS is normally parallel to the Z-axis, the outer surface LB12-d may be inclined with respect to the Z-axis. Incidentally, the inclination angle of the outer side surface LB12-d with respect to the Z axis may be any angle. As an example, the inclination angle of the outer surface LB12-d with respect to the Z axis may be 2 degrees. The outer surface LB12-d may converge inwardly downward from the outer surface LB11-d. That is, the insertion portion LB1-d may have a tapered shape that converges inward toward the bottom at a position including the outer side surface LB12-d. In other words, the size of the insertion portion LB1-d along the direction along the XY plane (that is, the cross direction described above) decreases downward from the outer surface LB11-d at the position including the outer surface LB12-d. It may have a tapered shape.

When the outer surface LB10d includes such an outer surface LB12-d, the lid member LB is attached to the blade part TB0 compared to the case where the outer surface LB10-d is parallel to the inner surface IWS of the blade part TB0. -d, the adhesion between the blade part TB0 and the lid member LB-d is improved. Therefore, the lid member LB-d can be appropriately arranged on the blade component TB0.

Incidentally, when the outer surface LB10-d includes the outer surfaces LB11-d and LB12-d, as shown in FIG. The boundary BD between LB11-d and the outer surface LB12-d may be in contact with the inner surface IWS of the blade part TB0. In other words, the outer surface LB10-d of the lid member LB-d does not have to contact the inner surface IWS of the blade part TB0 at a position different from the boundary BD. In this case, the outer side surface LB10-d of the lid member LB-d may be considered to be in contact with the inner side surface IWS of the blade part TB0 within the cross section including the Z axis.

Next, the projecting portion LB2-d differs from the projecting portion LB2 shown in FIGS. 8(a) and 8(b) in that its shape is different. Specifically, the projection LB2-d is such that the outer surface LB23-d of the projection LB2-d faces the surface of the outer wall OM of the blade component TB0 (in particular, the upper wall CM in which the hole TH is formed). It differs from the protrusion LB2 in that it does not have to be vertical, which includes an outer surface perpendicular to the surface of the outer wall OM of the blade part TB0 (especially the upper wall CM in which the hole TH is formed). Since the surface of the outer wall OM of the blade part TB0 (particularly, the upper wall CM in which the hole TH is formed) is normally perpendicular to the Z-axis, the outer surface LB23-d is inclined with respect to the Z-axis. may be Incidentally, the inclination angle of the outer side surface LB23-d with respect to the Z axis may be any angle. As an example, the inclination angle of the outer side surface LB23-d with respect to the Z axis may be 15 degrees. The outer surface LB23-d may widen outward toward the bottom. That is, the projecting portion LB2-d may have a tapered shape that widens outward toward the bottom at a position including the outer side surface LB23-d. In other words, the projecting portion LB2-d has a tapered shape in which the size along the direction along the XY plane (that is, the cross direction described above) increases toward the bottom at a position including the outer side surface LB23-d. may be

When the projecting portion LB2-d includes such an outer surface LB23-d, the lid member LB-d substantially functions as the lid member LB-a described in the first modified example. It is possible. That is, the thickness of the projecting portion LB2-d of the lid member LB-d is not constant. Therefore, in the fourth modification, as in the first modification, in order to bond the lid member LB-d to the blade part TB0, the modeling apparatus SYS (or ) may irradiate the relatively thin portion of the protruding portion LB2-d with the shaping light EL (or an energy beam, etc.). As a result, a part of the projecting portion LB2-d is easily melted compared to the case where the relatively thick portion of the projecting portion LB2-d is irradiated with the shaping light EL. As a result, the lid member LB-d is properly joined to the blade component TB0. That is, the lid member LB-d can enjoy the same effects as the above-described lid member LB-a.

In order to enjoy the technical effect of reducing the possibility of interference between the blade part TB0 and the lid member LB-d, as shown in FIGS. d, a groove GV may be formed in the facing surface LB221 of the projecting member LB2-d (especially the second portion LB22) capable of facing the outer wall OM of the blade part TB0. In particular, the groove GV may be formed at or near the boundary between the first portion LB21 and the second portion LB22 on the facing surface LB221. In other words, a gap forming the groove GV may be formed between the facing surface LB221 of the protruding member LB2-d and the blade component TB0. Even in this case, the blade component TB0 and the lid member LB-d may interfere with each other when the lid member LB-d is arranged on the blade component TB0 compared to the case where the groove GV is not formed in the facing surface LB221. become less sexual. Therefore, the lid member LB-d can be smoothly arranged on the blade component TB0.

In addition to or instead of the groove GV that forms a gap between the facing surface LB221 of the protruding member LB2-d and the blade component TB0, the outer surface LB10-d of the insert member LB1-d and the blade component TB0 (particularly, A groove may be formed to form a gap with the side surface (IWS).

It should be noted that in the fourth modified example as well, configuration requirements peculiar to at least one of the first to third modified examples may be employed. The structural requirements specific to the third modification may include, for example, a structural requirement that a lid member LB that collectively closes at least two holes TH may be used.

Further, in the embodiment and the first to fourth modifications described above, the shape of the lid member does not have to be rotationally symmetrical. Similarly, the shape of the hole TH may not be rotationally symmetrical.

(4-5) Fifth Modified Example In the fifth modified example, the modeling apparatus SYS sets the distance D3 between the modeling surface MS and the processing head 21 (particularly, the modeling surface MS and the material nozzle 212 (in particular, the supply outlet 214 ), the amount of processing by the additional processing (that is, the size of the object formed on the modeling surface MS by the additional processing, for example, the height of the structure layer SL described above) varies depending on the distance D3) between (This function is hereinafter referred to as a "self-alignment function"). The self-alignment function will be described below with reference to FIGS. 30 and 31. FIG.

FIG. 30 shows supply routes of the modeling material M from the plurality of material nozzles 212. FIG. As shown in FIG. 30, the supply outlets 214 of the multiple material nozzles 212 may face different directions to achieve a self-alignment function. For example, the feed outlet 214 of the first material nozzle 212 faces in a first direction and the feed outlet 214 of the second material nozzle 212 faces in a second direction different from the first direction. good too. Since the supply direction of the build material M from the material nozzles 212 changes when the direction in which the supply outlets 214 are facing changes, the plurality of material nozzles 212 are arranged along different supply directions in order to achieve the self-alignment function. The modeling material M may be supplied. For example, a first material nozzle 212 supplies build material M along a first supply direction, and a second material nozzle 212 differs from the first supply direction (typically the first The build material M may be fed along a second feed direction (intersecting the feed direction). Furthermore, in order to achieve a self-alignment function, the material nozzles 212 are aligned such that the supply paths of the building material M from the supply outlets 214 pointing in different directions intersect in the concentration area CP. may be That is, the plurality of material nozzles 212 may be aligned such that the building material M supplied from the plurality of supply outlets 214 facing in different directions is supplied toward the concentration area CP. In other words, the plurality of material nozzles 212 may be aligned such that the supply directions of the modeling material M from the plurality of material nozzles 212 intersect in the concentration region CP.

In the example shown in FIG. 30, the concentrated area CP is located below the modeling surface MS (that is, a position away from the modeling surface MS on the -Z side). In this case, the modeling apparatus SYS performs additional processing on the modeling surface MS in a state in which the modeling material M supplied from the material nozzle 212 reaches the modeling surface MS before actually reaching the concentrated area CP. However, the concentrated area CP may be located on the modeling surface MS. That is, the modeling apparatus SYS may perform additional processing on the modeling surface MS in a state in which the modeling material M supplied from the material nozzle 212 reaches the concentrated area CP and simultaneously reaches the modeling surface MS. Alternatively, the concentrated area CP may be located above the modeling surface MS (that is, a position away from the modeling surface MS on the +Z side). That is, the modeling apparatus SYS may perform additional processing on the modeling surface MS in a state in which the modeling material M supplied from the material nozzle 212 reaches the modeling surface MS after actually reaching the concentrated area CP.

In this case, according to the distance D3 between the modeling surface MS and the processing head 21, the size of the model added to the modeling surface MS by the additional machining (in the example shown in FIG. 30, the size in the Z-axis direction, hereinafter referred to as "amount of modeling") fluctuates.

Specifically, as shown in FIG. 30, the longer the distance D3, the shorter the distance D4 between the concentrated area CP and the modeling surface MS. As a result, the amount of the modeling material M supplied from the material nozzle 212 to the molten pool MP increases. This is because the shorter the distance D4, the closer the concentrated area CP where the modeling material M concentrates to the modeling surface MS. As the amount of the modeling material M supplied to the molten pool MP increases, the amount of the modeling material M melted in the molten pool MP increases. As the amount of the modeling material M that melts in the molten pool MP increases, the amount of the modeling material M that solidifies on the modeling surface MS increases. As a result, the height of the modeled object made of the solidified modeling material M increases. Therefore, as shown in FIG. 31, there is a relationship between the distance D4 and the amount of modeling such that the shorter the distance D4, the greater the amount of modeling. That is, there is a relationship between the distance D4 and the amount of modeling such that the longer the distance D4, the smaller the amount of modeling. Similarly, as shown in FIG. 31, there is a relationship between the distance D3 and the amount of modeling such that the longer the distance D3, the greater the amount of modeling. In other words, there is a relationship between the distance D3 and the amount of modeling such that the shorter the distance D3, the smaller the amount of modeling.

In FIG. 31, the distance D4 when the concentrated area CP is positioned above the modeling surface MS is a positive distance, and the distance D4 when the concentrated area CP is positioned below the modeling surface MS is a negative distance. showing a graph. As described above, the modeling apparatus SYS operates on the modeling surface MS in a state in which the concentrated area CP is positioned below the modeling surface MS (that is, the modeling surface MS is positioned between the concentrated area CP and the material nozzle 212). Additional processing is performed on Thus, the distance D4 has a range of values less than zero (referred to as the used area). In this case, the relationship that the shorter the distance D4 is, the larger the amount of modeling means the relationship that the smaller the absolute value of the distance D4 is, the larger the amount of modeling is. Similarly, the relationship that the longer the distance D4 is, the smaller the amount of modeling means the relationship that the larger the absolute value of the distance D4 is, the smaller the amount of modeling is. Therefore, in the following description, unless otherwise specified, the distance D4 means the absolute value of the distance D4.

The modeling apparatus SYS may use such a self-alignment function to perform additional processing on the blade component TB0 on which the lid member LB is arranged. That is, the modeling apparatus SYS may use such a self-alignment function to perform additional processing for modeling the additional portion OB on the blade component TB0 on which the lid member LB is arranged. Additional processing using the self-alignment function will be described below with reference to FIG.

The uppermost part of FIG. 32 shows the blade part TB0 (in particular, the blade part TB0 on which the lid member LB is already arranged) before the additional processing for forming the additional portion OB is performed. When additional processing is performed on the blade part TB0 on which the lid member LB is already arranged, as shown in FIG. The distance D3#1 between the modeling surface MS (that is, the surface of the blade part TB0) and the material nozzle 212 is the modeling surface MS (that is, the surface of the lid member LB) and the material nozzle 212 is longer than the distance D3#2. As a result, as shown in FIG. 32, the amount of modeling for the blade component TB0 is greater than the amount of modeling for the lid member LB. Therefore, each time the structural layer SL is formed on the blade part TB0 and the lid member LB, the height of the uppermost structural layer SL formed on the blade part TB0 and the height of the uppermost layer SL formed on the lid member LB The difference from the height of the structure layer SL gradually becomes smaller. As a result, as shown in FIG. 32, after the additional processing for forming the additional portion OB composed of the plurality of structural layers SL is performed, the additional portion OB formed on the blade component TB0 of the additional portion OB The difference between the height of the modeled object and the height of the modeled object formed on the lid member LB in the additional part OB is the difference between the height of the blade part TB0 and the height of the lid member LB before the additional processing is performed. be smaller than

As a result, the surface of the additional portion OB becomes relatively flat compared to when the self-alignment function is not used. Therefore, in the fifth modification, the modeling apparatus SYS can model the additional portion OB with relatively little variation in height. As a result, the modeling apparatus SYS can manufacture the turbine blade TB with relatively high accuracy.

It should be noted that, in the fifth modified example as well, configuration requirements specific to at least one of the first to fourth modified examples may be employed. The configuration requirements specific to the fourth modification may include, for example, configuration requirements related to the lid member LB-d.

(4-6) Sixth Modification In the sixth modification, the modeling apparatus SYS attaches the additional portion OB to the blade part TB0 having the outer wall OM formed with the hole AP1 different from the hole TH closed by the lid member LB. Additional processing for shaping may be performed. In the following description, the blade part TB0 having the hole AP1 formed in the outer wall OM will be referred to as "blade part TB0-f".

An example of a blade part TB0-f with a hole AP1 formed in the outer wall OM is shown in FIG. The hole AP1 is a through hole penetrating the outer wall OM. The hole AP1 is a through hole that connects the space SP0 inside the blade part TB0-f and the space outside the blade part TB0-f. In the example shown in FIG. 33, a hole AP1 is formed in the upper wall CM of the outer walls OM of the blade part TB0-f. However, the hole AP1 may be formed in a wall portion of the outer wall OM that is different from the top wall CM. Also, in the example shown in FIG. 33, three holes AP1 are formed. However, two or less holes AP1 may be formed, or four or more holes AP1 may be formed.

When additional processing is performed on the blade part TB0-f in which such a hole AP1 is formed in the outer wall OM, as shown in FIG. Additional processing may be performed to shape the additional portion OB on the blade component TB0-f. In this case, the space SP0 inside the blade part TB0-f and the space outside the blade part TB0-f may be connected via holes AP1 and AP2.

Alternatively, the modeling apparatus SYS forms a hole AP3 leading to the hole TH closed by the lid member LB in addition to or instead of performing the additional processing of shaping the additional portion OB in which the hole AP2 leading to the hole AP1 is formed. Additional processing for shaping the additional portion OB may be performed. Specifically, as shown in FIG. 35, first, a lid member LB having a hole AP4 connected to the hole TH may be arranged on the blade part TB0-f. After that, the shaping apparatus SYS may perform additional processing to shape an additional portion OB in which a hole AP3 leading to the hole AP4 (that is, a hole AP3 leading to the hole TH via the hole AP4) is formed. Note that the modeling apparatus SYS performs additional processing to form an additional portion OB in which a hole AP3 connected to the hole TH is formed for the blade part TB0 in which the hole TH is formed but the hole AP1 is not formed. you can go

Not limited to the blade part TB0, the modeling apparatus SYS can provide any work W having a second hole formed in the outer wall that is different from the first hole closed by the lid member. Additional processing may be performed to shape the additional portion having the third hole formed therein. The modeling apparatus SYS is for forming an additional portion in which a fourth hole connecting to the first hole is formed for an arbitrary work W in which the first hole closed by the cover member is formed in the outer wall. Processing may be performed.

Also, in the sixth modified example, configuration requirements specific to at least one of the first to fifth modified examples may be adopted. The configuration requirements specific to the fifth modification may include, for example, configuration requirements related to the self-alignment function.

(4-7) Seventh Modification In the seventh modification, a plurality of works W may be placed on the stage 31 . In this case, the modeling apparatus SYS may perform additional processing on a plurality of works W. FIG. For example, as shown in FIG. 36 showing a stage 31 on which a plurality of works W are placed, a plurality of blade parts TB0 may be placed as a plurality of works W on the stage 31 . As shown in FIG. 36 , the plurality of blade parts TB0 may be mounted on the mounting surface 311 of the stage 31 via the jig 33 . However, the plurality of blade parts TB0 may be mounted on the mounting surface 311 of the stage 31 without the jig 33 interposed therebetween.

In the seventh modification, the multiple blade parts TB0 placed on the stage 31 may have the same characteristics. The properties of the blade part TB0 may include the type of material that makes up the blade part TB0 and the shape of the blade part TB0. The state in which "the plurality of blade parts TB0 have the same properties" is not limited to the state in which "the plurality of blade parts TB0 have exactly the same properties", but also the state in which "the plurality of blade parts TB0 have substantially the same properties". It may also contain a state. The state in which "the plurality of blade parts TB0 have substantially the same characteristics" means that "at least two blade parts TB0 out of the plurality of blade parts TB0 have different characteristics, but the at least two blade parts TB0 have different characteristics. It may include "a state that falls below the allowable value". As an example, turbine blades TB manufactured from blade part TB0 are typically attached to a rotor that makes up the turbine and is rotatable about an axis of rotation. A rotor is usually fitted with a plurality of turbine blades TB having the same characteristics. In the seventh modification, multiple blade parts TB0 for respectively manufacturing multiple turbine blades TB to be attached to the same turbine may be considered to be multiple blade parts TB0 having the same characteristics.

When a plurality of blade parts TB0 having the same characteristics are placed on the stage 31, the modeling apparatus SYS forms the additional portion OB on one blade part TB0 of the plurality of blade parts TB0. The molding control information (for example, molding pass information) used in the above may be used to mold the additional portion OB on another blade part TB0 different from one blade part TB0 out of the plurality of blade parts TB0. In other words, the modeling apparatus SYS performs additional processing for modeling the additional portion OB on another blade part TB0 based on modeling control information (for example, modeling path information) used for modeling the additional portion OB on one blade part TB0. may be performed. In this case, since it is not necessary to generate a plurality of pieces of modeling control information corresponding to each of the plurality of blade parts TB0, the modeling apparatus SYS can shorten the time required for additional machining of the plurality of blade parts TB0.

(4-8) Eighth Modified Example In the above description, the molding apparatus SYS or a manufacturing apparatus different from the molding apparatus SYS manufactures the lid member LB, and the manufactured lid member LB is arranged on the blade part TB0. On the other hand, in the eighth modification, the modeling apparatus SYS may directly model the lid member LB on the blade part TB0. In other words, the modeling apparatus SYS may set a modeling surface MS in a portion of the blade part TB0 where the lid member LB is to be modeled, and may model the lid member LB on the set modeling surface MS. In this case, since the lid member LB integrated with the blade part TB0 is molded on the blade part TB0, the lid member LB is already fixed to the blade part TB0 at the time the lid member LB is molded on the blade part TB0 ( jointed). Therefore, the above-described operation of fixing (for example, joining) the lid member LB to the blade component TB0 is no longer necessary, thereby improving the throughput of manufacturing the turbine blade TB.

In order to form the lid member LB on the blade part TB0, the modeling apparatus SYS may repeat the operation of modeling the structural layer SL along the hole TH. Specifically, the modeling apparatus SYS may model the structural layer SL-1 along the hole TH, and then model the structural layer SL-2 along the structural layer SL-1. After that, the modeling apparatus SYS may model a new structural layer SL along the modeled structural layer SL, if necessary. As a result, the lid member LB including at least the structural layer SL-1 and the structural layer SL-2 is formed.

As described above, examples of the cross-sectional shape of the hole TH include a circular shape and a polygonal shape. Therefore, for convenience of explanation, a first forming operation for forming a cover member LB for closing a hole TH having a circular cross-sectional shape on the blade part TB0 and a hole TH having a polygonal cross-sectional shape will be described below. A second molding operation for molding the cover member LB for closing on the blade part TB0 will be described. However, the molding apparatus SYS may mold a cover member LB for closing the hole TH having an arbitrary cross-sectional shape on the blade part TB0.

The structural layer SL formed along the hole TH (for example, the structural layer SL-1 described above) is the structural layer SL formed along the inner side surface IWS of the blade component TB0 facing the hole TH. Therefore, it may be called an inner peripheral structure layer (inner peripheral portion). The structural layer SL formed along the inner peripheral structural layer (for example, the structural layer SL-2 formed along the structural layer SL-1 described above) is also formed along the inner surface of the inner peripheral structural layer. Therefore, it may be called an inner peripheral structural layer (inner peripheral portion).

Further, when the modeling apparatus SYS forms the lid member LB on the blade component TB0, the stage drive system 32 provided in the modeling apparatus SYS moves the stage 31 along at least one of the θX direction and the θY direction and the θZ direction. can be moved. In the following description, for convenience of description, an example in which the stage drive system 32 moves the stage 31 along each of the θX direction and the θZ direction will be described. That is, in the following description, an example will be described in which the stage drive system 32 rotates the stage 31 around a rotation axis along the X axis and a rotation axis along the Z axis. In the following description, for convenience of explanation, the axis of rotation along the X-axis is called the A-axis, and the axis of rotation along the Z-axis is called the C-axis.

(4-8-1) First molding operation for molding lid member LB First , referring to FIGS. 37 to 43, a first molding operation for molding lid member LB for closing hole TH having a circular cross-sectional shape is performed. A modeling operation will be described.

First, the blade component TB0 is placed on the stage 31 as shown in FIG. In the eighth modification, the blade component TB0 is placed on the stage 31 so that the C-axis passes through the center of the hole TH (that is, the center of the circle that is the shape of the hole TH). For example, the user may manually place the blade component TB0 on the stage 31 so that the C-axis passes through the center of the hole TH. Alternatively, for example, a device for placing the blade part TB on the stage 31 may automatically place the blade part TB0 on the stage 31 so that the C-axis passes through the center of the hole TH. In this case, the device for placing the blade part TB on the stage 31 includes information about the position of the C-axis of the stage 31 and information about the shape of the blade part TB (for example, model data indicating the shape of the blade part TB and blade The blade component TB0 may be automatically placed on the stage 31 based on at least one measurement data indicating the measurement result of the shape of the component TB. Incidentally, at the timing when the blade component TB0 is mounted on the stage 31, the mounting surface 311 of the stage 31 may be parallel to the XY plane. That is, the stage 31 does not have to be tilted with respect to the Z axis. Here, the C-axis is normally an axis orthogonal to the mounting surface 311 of the stage 31 . Therefore, at the timing when the blade component TB0 is placed on the stage 31, the C-axis may be parallel to the Z-axis.

However, the blade component TB0 may be placed on the stage 31 so that the C-axis does not pass through the center of the hole TH. For example, the stage 31 may be a first stage rotatable about each of the A and C axes and movable relative to the first stage (e.g., along at least one of the X, Y and Z axes). ), the blade component TB0 may be placed on the stage 31 (especially the second stage) so that the C-axis does not pass through the center of the hole TH. In this case, the second stage on which the blade component TB0 is placed may move so that the C-axis passes through the center of the hole TH.

After that, the control device 7 moves the stage 31 so that the modeling unit 2 can model the structural layer SL-1 along the hole TH. Specifically, the structural layer SL-1 formed along the hole TH is formed on at least a portion of the inner surface IWS of the blade part TB0 facing the hole TH. For this reason, the control device 7 adjusts the direction of the inner surface IWS so that the shaping light EL from the modeling unit 2 can irradiate at least a part of the inner surface IWS and the modeling material M from the shaping unit 2 is at least on the inner surface IWS. The stage 31 is moved so as to have a predetermined orientation that allows supply to a part. Specifically, as shown in FIG. 38, the control device 7 controls the stage drive system 32 so that the stage 31 rotates around the A axis (that is, around the X axis). That is, the control device 7 controls the stage drive system 32 so that the stage 31, which was not tilted with respect to the Z axis, tilts with respect to the Z axis. The control device 7 controls the stage driving system 32 so that the tilt angle of the stage 31 with respect to the Z-axis becomes a predetermined angle (that is, controls the tilt angle of the stage 31). As a result, as shown in FIG. 38, the mounting surface 311 of the stage 31 is tilted with respect to the Z axis. That is, the C-axis, which is the rotation axis of the stage 31, is tilted with respect to the Z-axis.

Furthermore, in parallel with or before or after the movement of the stage 31, the control device 7 moves the shaping head 21 so that the shaping unit 2 can shape the structural layer SL-1 along the hole TH. may That is, the control device 7 may move the irradiation optical system 211 and the material nozzle 212 included in the modeling head 21 so that the modeling unit 2 can model the structural layer SL-1 along the hole TH. Specifically, as described above, the structural layer SL-1 shaped along the hole TH is shaped on at least a portion of the inner surface IWS of the blade part TB0 facing the hole TH. Therefore, the control device 7 moves the modeling head 21 so that the modeling unit 2 can irradiate at least part of the inner surface IWS of the blade part TB0 with the modeling light EL and supply the modeling material M. . That is, the control device 7 controls the shaping head 21 so that the shaping head 21 is positioned at the first position where it can irradiate at least part of the inner surface IWS with the shaping light EL and supply the shaping material M. The modeling head 21 may be moved. As an example, the control device 7 may move the shaping head 21 so that the condensing position of the shaping light EL is set at or near the inner surface IWS of the blade component TB0.

After that, the modeling apparatus SYS models the structural layer SL-1 along the hole TH. That is, the modeling apparatus SYS models the structural layer SL-1 along the hole TH while the stage 31 is tilted with respect to the Z-axis by the control device 7 as shown in FIG. The modeling apparatus SYS models the structural layer SL-1 along the hole TH while the tilt angle of the stage 31 is controlled by the control device 7 as shown in FIG. The modeling apparatus SYS is in a state where the movement of the modeling head 21 is controlled by the control device 7 as shown in FIG. The structure layer SL-1 is formed along the hole TH in the state of being formed. Specifically, as shown in FIG. 39, the modeling apparatus SYS irradiates at least part of the inner surface IWS with the shaping light EL and supplies the modeling material M along the hole TH (that is, the inner surface IWS). (along side IWS) to shape structural layer SL-1;

In the first modeling operation, while the modeling head 21 irradiates at least part of the inner surface IWS with the modeling light EL and supplies the modeling material M, the control device 7 controls the stage 31 to move around the C axis. The stage driving system 32 is controlled so as to rotate. For example, the control device 7 may control the stage drive system 32 so that the stage 31 rotates 360 degrees around the C-axis. That is, the modeling apparatus SYS models the structure layer SL-1 while the rotation of the stage 31 (for example, rotation about the C-axis) is controlled by the control device 7 . In other words, the modeling apparatus SYS models the structural layer SL-1 while the stage 31 is being rotated by the control device 7 (for example, rotating around the C-axis). As a result, on the inner surface IWS, the target irradiation position EA irradiated with the shaping light EL and the target supply position MA supplied with the modeling material M relatively move along the circumferential direction. For this reason, the modeling head 21 continuously (or intermittently) irradiates the inner surface IWS distributed along the circumferential direction around the C-axis with the shaping light EL along the circumferential direction. Material M will be supplied.

As a result, as shown in FIGS. 40(a) and 40(b), an annular (or ring-shaped) structural layer SL-1 distributed along the hole TH is formed on the inner surface IWS. That is, an annular structural layer SL-1 distributed along the inner surface IWS of the blade part TB0 facing the hole TH is shaped on the inner surface IWS. Incidentally, FIG. 40(b) is a top view of the blade part TB0 on which the structural layer SL-1 is formed.

After that, the modeling apparatus SYS models the structure layer SL-2 along the hole TH. Specifically, the controller 7 controls the stage drive system 32 so that the stage 31 continues to tilt with respect to the Z axis. The control device 7 controls the stage driving system 32 so that the tilt angle of the stage 31 with respect to the Z axis is maintained at a predetermined angle (that is, controls the tilt angle of the stage 31). That is, the tilted state (in other words, rotating state) of the stage 21 while the structural layer SL-2 is formed is the tilted state (in other words, rotated state) of the stage 21 while the structural layer SL-1 is formed. may be the same as

On the other hand, the control device 7 may move the modeling head 21 so that the modeling unit 2 can model the structural layer SL-2 along the hole TH. Specifically, as described above, the structural layer SL-2 formed along the hole TH is at least part of the structural layer SL-1 (and in some cases, at least part of the blade part TB0). ) is shaped. Therefore, the control device 7 causes the modeling unit 2 to irradiate at least a portion of the structural layer SL-1 (furthermore, at least a portion of the blade part TB0 in some cases) with the modeling light EL and the modeling material M The shaping head 21 may be moved so as to supply the . That is, the control device 7 causes the modeling head 21 to irradiate at least a portion of the structural layer SL-1 (and, in some cases, at least a portion of the blade part TB0) with the modeling light EL and supply the modeling material M. The shaping head 21 may be moved so that the shaping head 21 is positioned at the second position where the shaping head 21 can be. As an example, the control device 7 may move the shaping head 21 so that the condensing position of the shaping light EL is set at or near the structural layer SL-1.

After that, the modeling apparatus SYS models the structure layer SL-2 along the hole TH. That is, while the stage 31 is tilted with respect to the Z-axis by the control device 7, the modeling apparatus SYS moves the structure layer SL-2 along the hole TH, similarly to the case where the structure layer SL-1 is modeled. to shape. The modeling apparatus SYS models the structural layer SL-2 along the hole TH while the tilt angle of the stage 31 is controlled by the control device 7 in the same manner as when the structural layer SL-1 is formed. The modeling apparatus SYS sets the movement of the modeling head 21 to a state where the control device 7 controls the movement of the modeling head 21 (for example, the modeling head 21 is positioned at the second position described above), as in the case where the structural layer SL-1 is modeled. 2), the structural layer SL-2 is modeled along the hole TH. Specifically, as shown in FIG. 41, the modeling apparatus SYS irradiates at least a portion of the structural layer SL-1 (and, in some cases, at least a portion of the blade part TB0) with the shaping light EL. In addition, by supplying the modeling material M, the structural layer SL-2 is modeled along the hole TH (that is, along the inner side surface IWS).

The operation of modeling the structural layer SL-2 may be the same as the operation of modeling the structural layer SL-1. For this reason, the period during which the modeling head 21 irradiates at least part of the structural layer SL-1 (and, in some cases, at least part of the blade part TB0) with the modeling light EL and supplies the modeling material M Inside, the controller 7 controls the stage drive system 32 so that the stage 31 rotates around the C-axis. For this reason, the shaping head 21 continuously distributes the structural layer SL-1 (and, in some cases, the blade component TB0) along the circumferential direction around the C-axis ( Alternatively, the modeling light EL is applied and the modeling material M is supplied intermittently.

As a result, as shown in FIGS. 42A and 42B, an annular (or ring-shaped) structural layer SL-2 distributed along the hole TH is formed on the first structural layer SL-2. is shaped into That is, a ring-shaped structure layer SL-2 distributed along the inner side surface of the ring-shaped structure layer SL-1 facing the hole TH is formed on the structure layer SL-1. Incidentally, FIG. 42(b) is a top view of the blade component TB0 on which the structural layer SL-2 is formed.

After that, the same operation is repeated until all structural layers SL constituting the lid member LB are formed. As a result, as shown in FIGS. 43(a) and 43(b), a lid member LB composed of a plurality of structural layers SL is formed. That is, the lid member LB that covers the hole TH is formed.

As shown in FIG. 43(a), the upper surface LBs of the lid member LB may be parallel to the surface of the outer wall OM of the blade part TB0 (in particular, the surface CMs of the upper wall CM in which the hole TH is formed). . In other words, the shaping apparatus SYS may shape the lid member LB such that the upper surface LBs of the lid member LB is parallel to the surface CMs of the upper wall CM of the blade part TB0. In other words, the hole TH is provided on the first surface that intersects the optical axis of the irradiation optical system 211 (an axis parallel to the Z axis), and the lid member LB is provided on the second surface that intersects the optical axis of the irradiation optical system 211. WHEREIN: The 1st surface in which the hole TH is provided and the 2nd surface in which the cover member LB is provided may be parallel. That is, the shaping apparatus SYS may shape the lid member LB such that the first surface on which the hole TH is provided and the second surface on which the lid member LB is provided are parallel. Note that the upper surface LBs of the lid member LB may mean the surface facing the irradiation optical system 211 among the surfaces of the lid member LB. On the other hand, if the top surface LBs of the lid member LB is not parallel to the surface CMs of the top wall CM of the blade component TB0, then the top surface LBs of the lid member LB should be parallel to the surface CMs of the top wall CM of the blade component TB0. A first additional process for doing so may be performed on the lid member LB. The first additional processing may include at least one of additional processing and removal processing. The first additional machining may be performed by the modeling apparatus SYS. The first additional machining may be performed by a processing device different from the modeling device. The first additional machining may be performed manually by humans.

As shown in FIG. 43(a), even if the upper surface LBs of the lid member LB is flush with the surface of the outer wall OM of the blade part TB0 (in particular, the surface CMs of the upper wall CM in which the hole TH is formed). good. In other words, the shaping apparatus SYS may shape the lid member LB such that the upper surface LBs of the lid member LB is flush with the surface CMs of the upper wall CM of the blade part TB0. In other words, the hole TH is provided on the first surface that intersects the optical axis of the irradiation optical system 211 (an axis parallel to the Z axis), and the lid member LB is provided on the second surface that intersects the optical axis of the irradiation optical system 211. WHEREIN: The 1st surface in which the hole TH is provided and the 2nd surface in which the cover member LB is provided may be flush. That is, the shaping apparatus SYS may shape the lid member LB so that the first surface on which the hole TH is provided and the second surface on which the lid member LB is provided are flush with each other. What is the state in which "one surface and the other surface are flush with each other"? It may mean a state in which there is no step between one surface and another surface (specifically, there is no step in the direction intersecting the one surface and the other surface). "A state in which there is no step between one surface and another surface" includes not only a state in which there is no step between one surface and another surface, but also a state in which there is no step between one surface and another surface. A state in which there is a step equal to or smaller than the allowable upper limit size may also be included. On the other hand, if the top surface LBs of the lid member LB is not flush with the surface CMs of the top wall CM of the blade component TB0, then the top surface LBs of the lid member LB is flush with the surface CMs of the top wall CM of the blade component TB0. A second additional process for uniformity may be performed on the lid member LB. The second additional processing may include at least one of additional processing and removal processing. The second additional machining may be performed by the modeling apparatus SYS. The second additional machining may be performed by a processing device different from the modeling device. The second additional machining may be performed manually by humans.

When forming the structural layer SL-2 on the structural layer SL-1, the modeling apparatus SYS starts forming the structural layer SL-2 on a portion of the structural layer SL-1 near the bottom of the hole TH. may be set to the start position of As an example, in a situation where the height of each portion of the upper surface LBs of the lid member LB increases as it approaches the center of the upper surface LBs (that is, approaches the center of the hole TH), the modeling apparatus SYS , a portion of the structure layer SL-1 near the bottom of the hole TH may be set as the start position for starting the modeling of the structure layer SL-2. In this case, variations in height of each portion of the upper surface LBs of the lid member LB are reduced. That is, the upper surface LBs of the lid member LB is more likely to be flush with the surface of the outer wall OM of the blade part TB0 (in particular, the surface CMs of the upper wall CM in which the hole TH is formed). In other words, the upper surface LBs of the lid member LB is less likely to protrude from the surface of the outer wall OM of the blade part TB0.

Incidentally, when the blade part TB0 in which a plurality of holes TH are formed is placed on the stage 31, the modeling apparatus SYS may sequentially form a plurality of lid members LB that respectively block the plurality of holes TH. . For example, when the blade part TB0 in which the first hole TH and the second hole TH are formed is placed on the stage 31, the modeling apparatus SYS places the first lid covering the first hole TH. The member LB may be shaped, and then the second lid member LB closing the second hole TH may be shaped. When the first lid member LB that closes the first hole TH is formed, the blade part TB0 may be placed on the stage 31 so that the C-axis passes through the center of the first hole TH. (Alternatively, the second stage described above may move). When the second lid member LB that closes the second hole TH is formed, the blade part TB0 may be placed on the stage 31 so that the C-axis passes through the center of the second hole TH. (Alternatively, the second stage described above may move).

(4-8-2) Second molding operation for molding lid member LB Subsequently, referring to FIGS. 44 to 52, a second molding operation for molding lid member LB for closing hole TH having a polygonal cross-sectional shape is performed. 2 will be described. In the following description, for convenience of description, a second shaping operation for shaping the lid member LB for closing the hole TH having a triangular cross-sectional shape, which is an example of a polygonal shape, will be described. In addition, in the following description, the operations of the second modeling operation that are different from the first modeling operation will be mainly described. Therefore, in the second modeling operation, the same operation as the first modeling operation may be performed unless otherwise specified.

In the second modeling operation as well, the blade component TB0 is placed on the stage 31 (see FIG. 37) as in the first modeling operation. After that, in the second modeling operation, similarly to the first modeling operation, the control device 7 controls the stage 31 and the The modeling head 21 is moved (see FIG. 38). That is, the control device 7 sets the direction of the inner surface IWS to a predetermined direction in which the shaping light EL can irradiate at least a portion of the inner surface IWS and the modeling material M can be supplied to at least a portion of the inner surface IWS. , the stage 31 may be moved. The control device 7 may move the modeling head 21 so that the modeling unit 2 can irradiate at least part of the inner surface IWS of the blade part TB0 with the modeling light EL and supply the modeling material M. .

Here, in the second shaping operation, since the hole TH is triangular, as shown in FIG. IWS-1, inner side IWS-2 corresponding to the second side of the triangle, and inner side IWS-3 corresponding to the third side of the triangle. In this case, in order to form the structure layer SL-1, the modeling apparatus SYS models the structure layer SL-11, which is a part of the structure layer SL-1, on the inner surface IWS-1, and forms the structure layer SL-11 on the inner surface IWS-1. 2, a structural layer SL-12 which is part of the structural layer SL-1 is formed, and a structural layer SL-13 which is a part of the structural layer SL-1 is formed on the inner surface IWS-3. As a result, the structural layer SL-1 composed of the structural layers SL-11 to SL-13 is formed. It can also be said that the structural layers SL-11 to SL-13 are structural layers forming three sides of a triangle.

Therefore, the control device 7 first moves the stage 31 so that the modeling unit 2 can model the structural layer SL-11 on the inner surface IWS-1. That is, the control device 7 changes the orientation of the inner surface IWS-1 so that the shaping light EL can irradiate at least a portion of the inner surface IWS-1 and the modeling material M can be supplied to at least a portion of the inner surface IWS-1. The stage 31 is moved so as to have a predetermined orientation of . Furthermore, the control device 7 may move the modeling head 21 so that the modeling unit 2 can irradiate at least part of the inner surface IWS-1 with the modeling light EL and supply the modeling material M. .

After that, the modeling apparatus SYS models the structural layer SL-11 along the inner surface IWS-1. That is, as shown in FIG. 45, the modeling apparatus SYS models the structural layer SL-11 along the inner surface IWS-1 while the stage 31 is tilted with respect to the Z-axis by the control device 7 . The modeling apparatus SYS models the structure layer SL-11 along the inner surface IWS-1 while the tilt angle of the stage 31 is controlled by the control device 7 as shown in FIG. The modeling apparatus SYS models the structure layer SL-11 along the inner surface IWS-1 while the movement of the modeling head 21 is controlled by the control device 7 as shown in FIG. Specifically, as shown in FIG. 45, the modeling apparatus SYS irradiates at least a part of the inner surface IWS-1 with the shaping light EL and supplies the modeling material M, thereby to shape the structural layer SL-11. As a result, as shown in FIG. 46, the structural layer SL-11 is formed along the inner side surface IWS-1.

In the second modeling operation, unlike the first modeling operation, the control device 7 does not have to control the stage drive system 32 so that the stage 31 rotates around the C axis. In other words, the stage 31 does not need to rotate while the modeling head 21 irradiates at least part of the inner surface IWS-1 with the modeling light EL and supplies the modeling material M.

After that, the control device 7 moves the stage 31 and the modeling head 21 so that the modeling unit 2 can model the structural layer SL-12 on the inner surface IWS-2. That is, the control device 7 changes the orientation of the inner surface IWS-2 so that the shaping light EL can irradiate at least a portion of the inner surface IWS-2 and the modeling material M can be supplied to at least a portion of the inner surface IWS-2. The stage 31 is moved so as to have a predetermined orientation of . Specifically, in order to move the stage 31 so that the inner surface IWS-2 is oriented in a predetermined direction, the controller 7 rotates the stage 31 about the C-axis by a desired angle and then stops. The stage drive system 32 may be controlled. The desired angle may be 360/n degrees when the cross-sectional shape of the hole TH is n (where n is an integer equal to or greater than 3) polygon. Therefore, when the cross-sectional shape of the hole TH is triangular, the control device 7 may control the stage driving system 32 so as to rotate the stage 31 about the C-axis by 120 degrees. As a result, the inner surface IWS-2 is positioned in the area where the inner surface IWS-1 was positioned before the stage 31 rotated by the desired angle. As a result, the modeling unit 2 can irradiate at least part of the inner surface IWS-2 with the modeling light EL and supply the modeling material M. As shown in FIG. Therefore, when the structural layer SL-12 is modeled after the structural layer SL-11 is modeled, the control device 7 does not necessarily have to move the modeling head 21 . However, the control device 7 may move the modeling head 21 as necessary.

After that, the modeling apparatus SYS models the structural layer SL-12 along the inner surface IWS-2. The operation of shaping the structural layer SL-12 along the inner surface IWS-2 may be the same as the operation of shaping the structural layer SL-11 along the inner surface IWS-1. As a result, as shown in FIG. 47, the structural layer SL-12 is formed along the inner side surface IWS-2.

After that, the control device 7 moves the stage 31 and the modeling head 21 so that the modeling unit 2 can model the structural layer SL-13 on the inner surface IWS-3. That is, the control device 7 changes the orientation of the inner surface IWS-3 so that the shaping light EL can irradiate at least a portion of the inner surface IWS-3 and the modeling material M can be supplied to at least a portion of the inner surface IWS-3. The stage 31 is moved so as to have a predetermined orientation of . Specifically, the control device 7 may control the stage drive system 32 so as to rotate the stage 31 about the C-axis by a desired angle and then stop. As a result, the inner surface IWS-3 is positioned in the area where the inner surface IWS-2 was positioned before the stage 31 rotated by the desired angle. As a result, the modeling unit 2 can irradiate at least part of the inner surface IWS-3 with the modeling light EL and supply the modeling material M. As shown in FIG. Therefore, when the structural layer SL-13 is modeled after the structural layer SL-12 is modeled, the control device 7 does not necessarily have to move the modeling head 21 . However, the control device 7 may move the modeling head 21 as necessary.

After that, the modeling apparatus SYS models the structural layer SL-13 along the inner surface IWS-3. The operation of shaping the structural layer SL-13 along the inner surface IWS-3 may be similar to the operation of shaping the structural layer SL-11 along the inner surface IWS-1. As a result, as shown in FIG. 48, the structural layer SL-13 is formed along the inner surface IWS-3. As a result, the structural layer SL-1 composed of the structural layers SL-11 to SL-13 is formed on the inner surface IWS.

After that, the modeling apparatus SYS models the structural layer SL-2 along the hole TH. Specifically, the modeling apparatus SYS, similar to the case of modeling the structural layer SL-1, forms the structural layer SL-2, which is a part of the structural layer SL-2, in order to form the structural layer SL-2. 21 is modeled on the structural layer SL-11 (that is, part of the inner wall facing the hole surrounded by the structural layer SL-1), and the structural layer SL-22 which is part of the structural layer SL-2. is formed on the structural layer SL-12 (that is, a part of the inner wall facing the hole surrounded by the structural layer SL-1), and a structural layer SL-23 that is a part of the structural layer SL-2 is formed. Modeling is performed on the structural layer SL-13 (that is, the part of the inner wall facing the hole surrounded by the structural layer SL-1).

Therefore, the control device 7 first moves the stage 31 and the modeling head 21 so that the modeling unit 2 can model the structural layer SL-21 on the structural layer SL-11. The operation of moving the stage 31 and the shaping head 21 so that the shaping unit 2 can shape the structure layer SL-21 on the structure layer SL-11 is performed by the shaping unit 2 on the inner surface IWS-1. It may be similar to the operation of moving the stage 31 and the modeling head 21 so that the layer SL-11 can be modeled. After that, the modeling apparatus SYS models the structural layer SL-21 along the structural layer SL-11. The operation of modeling the structural layer SL-21 along the structural layer SL-11 may be the same as the operation of modeling the structural layer SL-11 along the inner surface IWS-1. As a result, as shown in FIG. 49, the structural layer SL-21 is formed along the structural layer SL-11. In this case, typically, the structural layer SL-21 formed along the structural layer SL-11 becomes a structural layer parallel to the structural layer SL-11.

After that, the control device 7 moves the stage 31 and the modeling head 21 so that the modeling unit 2 can model the structural layer SL-22 on the structural layer SL-12. The operation of moving the stage 31 and the shaping head 21 so that the shaping unit 2 can shape the structure layer SL-22 on the structure layer SL-12 is performed by the shaping unit 2 on the inner surface IWS-2. It may be similar to the operation of moving the stage 31 and the modeling head 21 so that the layer SL-12 can be modeled. After that, the modeling apparatus SYS models the structural layer SL-22 along the structural layer SL-12. The operation of modeling the structural layer SL-22 along the structural layer SL-12 may be the same as the operation of modeling the structural layer SL-12 along the inner surface IWS-2. As a result, as shown in FIG. 50, the structural layer SL-22 is formed along the structural layer SL-12. In this case, typically, the structural layer SL-22 formed along the structural layer SL-12 becomes a structural layer parallel to the structural layer SL-12.

After that, the control device 7 moves the stage 31 and the modeling head 21 so that the modeling unit 2 can model the structural layer SL-23 on the structural layer SL-13. The operation of moving the stage 31 and the shaping head 21 so that the shaping unit 2 can shape the structure layer SL-23 on the structure layer SL-13 is performed by the shaping unit 2 on the inner surface IWS-3. It may be similar to the operation of moving the stage 31 and the shaping head 21 so that the layer SL-13 can be shaped. After that, the modeling apparatus SYS models the structural layer SL-23 along the structural layer SL-13. The operation of modeling the structural layer SL-23 along the structural layer SL-13 may be the same as the operation of modeling the structural layer SL-13 along the inner surface IWS-3. As a result, as shown in FIG. 51, the structural layer SL-23 is formed along the structural layer SL-13. In this case, typically, the structural layer SL-23 formed along the structural layer SL-13 becomes a structural layer parallel to the structural layer SL-13.

After that, the same operation is repeated until all structural layers SL constituting the lid member LB are formed. As a result, as shown in FIG. 52, a lid member LB composed of a plurality of structural layers SL is formed. That is, the lid member LB that covers the hole TH is formed.

Also in the second modeling operation, similarly to the first modeling operation described with reference to FIG. The lid member LB may be shaped so as to be parallel and/or flush with the surfaces CMs of the . If the top surface LBs of the lid member LB is not parallel and/or flush with the surface CMs of the top wall CM of the blade component TB0, then the top surface LBs of the lid member LB should be aligned with the top wall CM of the blade component TB0. and/or a second additional work for making the upper surface LBs of the lid member LB flush with the surface CMs of the upper wall CM of the blade part TB0 is performed by the lid member It may be done for LB.

The above description is for the molding operation of molding the lid member LB for closing the hole TH having a triangular cross-sectional shape. A similar operation may be performed when forming the member LB. That is, the modeling apparatus SYS forms the structural layer SL-k (k is a variable representing an integer equal to or greater than 1 and equal to or less than the total number of the structural layers SL forming the lid member LB) to form the structural layer SL-k.
