Specifically, a 3D printer (3D printer) PR to which embodiments of a modeling system and a modeling method, a display device and a display method, and an advertising device and an advertising method are applied will be described.

Yes, in the vertical direction). Further, the rotation directions around the X axis, the Y axis, and the Z axis (in other words, the tilt direction) are referred to as a θX direction, a θY direction, and a θZ direction, respectively.
(1) Configuration of 3D printer PR
(1-1) External Configuration of 3D Printer PR The external configuration of the 3D printer PR will be described with reference to FIGS. FIG. 1 is a front view of the 3D printer PR. FIG. 2 is a left side view of the 3D printer PR. FIG. 3 is a right side view of the 3D printer PR. FIG. 4 is a rear view of the 3D printer PR. FIG. 5 is a plan view (top view) of the 3D printer PR. FIG. 6 is a bottom view (bottom view) of the 3D printer PR. 7 and 8 are three-dimensional views of the 3D printer PR drawn on the basis of the one-point perspective method, respectively.

  As shown in FIGS. 1 to 8, the 3D printer PR includes a base 11, a column 12, a column 13, a beam member 14, a beam member 15, a panel 16, a print head 20, and an irradiation device 30. , A stage 40, a moving mechanism 50, and a controller 60 are provided.

  The base 11 is a member that forms the basis of the 3D printer PR. The base 11 supports the columns 12 and 13. The base 11 supports the beam member 14, the beam member 15, and the print head 20 via the columns 12 and 13. The base 11 supports the stage 40 via the moving mechanism 50. A work space SP for modeling the three-dimensional structure is secured above the base 11. The shape of the base 11 along the XY plane is a triangle (for example, a Rouleau triangle). Inside the base 11, an accommodation space capable of accommodating at least one of the desired member and the desired device is secured. In the present embodiment, a part of the moving mechanism 50 (for example, an actuator 54 described later) and the controller 60 are accommodated in the accommodating space inside the base 11.

  The support | pillar 12 is a member which has the shape extended in a longitudinal direction. One end of the column 12 along the longitudinal direction is fixed to the base 11. The support column 12 is fixed to the base 11 so as to extend along the vertical direction (Z-axis direction). The support column 12 is fixed to the base 11 in the vicinity of the first vertex among the three vertices of the base 11 on the XY plane (that is, the three vertices of the triangle). The support column 12 is disposed around the work space SP. The column 12 supports the beam member 14. The support 12 supports the print head 20 via the beam member 14.

  The column 13 is a member having a shape that extends in the longitudinal direction. One end of the column 13 along the longitudinal direction is fixed to the base 11. The support column 13 is fixed to the base 11 so as to extend along the vertical direction (Z-axis direction). The support column 13 is fixed to the base 11 in the vicinity of a second vertex different from the first vertex among the three vertices of the base 11 on the XY plane. The support column 13 is disposed around the work space SP. The support column 13 supports the beam member 15. The support 13 supports the print head 20 via the beam member 15.

  The beam member 14 is a member having a shape extending in the longitudinal direction. One end of the beam member 14 is fixed to the other end of the column 12. The beam member 14 is fixed to the support column 12 so as to extend along the horizontal direction (XY plane). The beam member 14 starts from one end of the beam member 14 and extends toward the print head 20 disposed above the center of the base 11 on the XY plane. The other end of the beam member 14 is connected to the print head 20. The beam member 14 supports the print head 20. The beam member 14 is disposed around the working space SP (in particular, above).

  The beam member 15 is a member having a shape extending in the longitudinal direction. One end of the beam member 15 is fixed to the other end of the column 13. The beam member 15 is fixed to the support column 13 so as to extend along the horizontal direction (XY plane). The beam member 15 extends from one end of the beam member 15 toward the print head 20 disposed above the center of the base 11 on the XY plane. The other end of the beam member 15 is connected to the print head 20. The beam member 15 supports the print head 20. The beam member 15 is disposed around the working space SP (in particular, above).

  The panel 16 is a member (substantially a casing) that surrounds the base 11, the columns 12 and 13, and the beam members 14 and 15. The panel 16 is a member (housing) surrounding the work space SP. The panel 16 is fixed to the base 11. The shape of the panel 16 along the XY plane is the same as or similar to the shape of the base 11 along the XY plane. Accordingly, the shape of the panel 16 along the XY plane is a triangle (for example, a Rouleau triangle). The panel 16 is a member having transparency to visible light. Therefore, the user of the 3D printer PR can visually recognize the space inside the panel 16 (for example, the work space SP) via the panel 16.

  The print head 20 is disposed above the center of the base 11 on the XY plane. The print head 20 is arranged around the work space SP (particularly above). The print head 20 is supported by the beam members 14 and 15 around the working space SP (in particular, above). The position of the print head 20 is fixed. That is, the print head 20 does not move.

  The print head 20 performs a modeling process for modeling the three-dimensional structure. In order to perform the modeling process, the print head 20 includes a modeling head 21. The modeling head 21 performs at least a part of the modeling process. The modeling process includes a material supply process. The material supply process is a process of supplying the modeling material EL to at least a part of the work space SP in accordance with the movement of the stage 40. The modeling process includes a drying process. The drying process is a process of drying the modeling material EL supplied by the modeling head 21. As the modeling head performs the material supply process and the drying process, the three-dimensional structure is modeled in the work space SP.

  At the time when the modeling head 21 supplies the modeling material EL, the modeling material EL is a mixture of a plurality of particles EL1, a binding material EL2, and a liquid EL3. For this reason, the modeling material EL is a material in a liquid state. Each particle EL1 is a white particle. Each particle EL1 is a particle formed of a resin material (for example, a particle formed of polyamide). The plurality of particles EL1 may include particles (for example, glass beads, hollow glass beads, etc.) formed of an inorganic material. The plurality of particles EL1 may include particles formed of a metal material. The plurality of particles EL1 may include a plurality of types of particles having different materials. The plurality of particles EL1 can be bonded through a bonding material. The binding material EL2 has a characteristic that it is soluble in the liquid EL3. When the binding material EL2 is dissolved in the liquid EL3, the modeling material EL is in a liquid state, and the binding force of the plurality of particles EL1 through the binding material EL2 is relatively weak. In particular, the bonding force of the plurality of particles EL1 through the bonding material EL2 is so weak that the plurality of particles EL1 cannot sufficiently maintain the shape of the three-dimensional structure. On the other hand, when the binding material EL2 is not dissolved in the liquid EL3, the binding force of the plurality of particles EL1 through the binding material EL2 is relatively strong. In particular, the bonding force of the plurality of particles EL1 through the bonding material EL2 is so strong that the plurality of particles EL1 can sufficiently maintain the shape of the three-dimensional structure. As such a binding material EL2, for example, at least one of vinyl acetate and polyvinyl alcohol is used. For example, water is used as the liquid EL3 capable of dissolving the binding material.

  When the modeling material EL is dried, all or a part of the liquid EL3 evaporates (that is, is removed). As a result, the bonding material EL2 transitions from a state dissolved in the liquid EL3 to a state not dissolved in the liquid EL3. For this reason, the plurality of particles EL1 that have not been sufficiently bonded to sufficiently maintain the shape of the three-dimensional structure are bonded firmly enough to maintain the shape of the three-dimensional structure sufficiently. . Therefore, it can be said that the drying process is a bonding process in which a plurality of particles EL1 are bonded through the bonding material EL2. As a result, the modeling material EL transitions from a liquid state including the liquid EL3 to a substantially solid state. This can be said that the phase of the modeling material EL transitions from the liquid phase to the solid phase. In other words, the modeling material EL is solidified. Therefore, it can be said that the drying process is a solidification process for solidifying the modeling material EL. For this reason, a three-dimensional structure is modeled by performing a drying process with respect to modeling material EL supplied from modeling head 21 by material supply processing. However, the modeling process including the drying process only causes a change in which the binding force of the plurality of particles EL1 is increased, and the state of the plurality of particles EL1 itself (for example, shape, strength, structure, size, etc.) is substantially changed. There is no change. That is, the state of the plurality of particles EL1 itself is substantially maintained. Note that the solidified modeling material EL including the plurality of particles EL1 and the binding material EL2 may not include the liquid EL3. Or solidified modeling material EL containing several particle | grains EL1 and binding material EL2 may contain liquid EL3 so that a three-dimensional structure can be maintained.

  The print head 20 performs at least a part of the generation process for generating the modeling material EL from the three-dimensional structure modeled by the modeling process. In order to perform the generation process, the print head 20 includes a generation head 22 adjacent to the modeling head 21 along the XY plane. The generation head 22 performs generation processing. The generation process includes a liquid supply process. The liquid supply process is a process for supplying the solution LQ to the three-dimensional structure located in the work space SP. The solution LQ is the same as the liquid EL3 contained in the modeling material EL. For example, the solution LQ is water.

  By the liquid supply process, the binding material EL2 transitions from a state not dissolved in the solution LQ to a state dissolved in the solution LQ. As a result, the plurality of particles EL <b> 1 that are firmly bonded so that the shape of the three-dimensional structure can be sufficiently maintained are not firmly bonded so that the shape of the three-dimensional structure can be sufficiently maintained. That is, the modeling material EL changes from the solid state to the liquid state by the liquid supply process. It can be said that the three-dimensional structure is dissolved by the liquid supply process. For this reason, the liquid supply process is performed on the three-dimensional structure formed by the modeling process, so that the mixture of the plurality of particles EL1, the binding material EL2, and the solution LQ (that is, the modeling material EL) is liquid. Produced as a product from the feed process.

  However, the generation process including the liquid supply process only causes a change in which the binding force of the plurality of particles EL1 is weakened. The state of the plurality of particles EL1 itself (for example, shape, strength, structure, size, and the like) is changed. There is virtually no change. That is, the state of the plurality of particles EL1 itself is substantially maintained. In addition, as described above, the modeling process also does not substantially change the state of the plurality of particles EL1 itself. For this reason, the state of the plurality of particles EL1 included in the modeling material EL generated by the liquid supply process is the same as the state of the plurality of particles EL1 included in the modeling material EL used for the modeling process. Therefore, the modeling material EL generated by the liquid supply process can be reused as the modeling material EL for modeling the three-dimensional structure (that is, the modeling material EL used for the modeling process).

  The irradiation device 30 projects an image on the surface of the three-dimensional structure (specifically, all or part of the surface, the same applies hereinafter) based on the projection map technique. For this reason, an image appropriately overlapping with the three-dimensional structure is projected on the surface of the three-dimensional structure. When an image is projected on the surface of the three-dimensional structure, the three-dimensional structure is visually recognized by the user as a three-dimensional structure having an appearance like the projected image. Accordingly, it can be said that the irradiation device 30 projects an image on the surface of the three-dimensional structure to virtually color (in other words, color) the three-dimensional structure.

  In order to project an image, the irradiation device 30 includes a plurality of (in this embodiment, four) projection devices (that is, the projection device 31, the projection device 32, the projection device 33, and the projection device 34).

  The projection device 31 is attached to the column 12. The projection device 31 is attached to a portion of the column 12 closer to the base 11 than the beam member 14. The projection device 31 is disposed around the work space SP (in particular, forward, on the + Y axis direction side as viewed from the work space SP). The projection device 31 emits light toward a first surface that the projection device 31 can project out of the surface of the three-dimensional structure. The projection device 31 projects a first image that appropriately overlaps the first surface by emitting light toward the first surface.

  The projection device 32 is attached to the column 12. The projection device 32 is attached to a portion of the column 12 closer to the beam member 14 than the base 11. The projection device 32 is disposed around the work space SP (in particular, forward, on the + Y axis direction side as viewed from the work space SP). The projection device 32 emits light toward a second surface that the projection device 32 can project out of the surface of the three-dimensional structure. The projection device 32 projects a second image that appropriately overlaps the second surface by emitting light toward the second surface. At least a part of the second surface may overlap with at least a part of the first surface. In this case, at least a part of the second image may be the same as at least a part of the first image. Alternatively, the second surface may not overlap with the first surface. In this case, the second image is different from the first image.

  The projection device 33 is attached to the column 13. The projection device 33 is attached to a portion of the column 13 closer to the base 11 than the beam member 15. The projection device 33 is disposed around the work space SP (in particular, forward, on the + Y axis direction side as viewed from the work space SP). The projection device 33 emits light toward a third surface that the projection device 33 can project out of the surface of the three-dimensional structure. The projection device 33 projects a third image that appropriately overlaps the third surface by emitting light toward the third surface. At least a part of the third surface may overlap with at least a part of the first surface. In this case, at least a part of the third image may be the same as at least a part of the first image. Alternatively, the third surface may not overlap with the first surface. In this case, the third image is different from the first image. The same applies to the relationship between the third surface and the second surface (third image and second image).

  The projection device 34 is attached to the column 13. The projection device 33 is attached to a portion of the column 13 closer to the beam member 15 than the base 11. The projection device 34 is disposed around the work space SP (in particular, forward, on the + Y axis direction side as viewed from the work space SP). The projection device 34 emits light toward the fourth surface that the projection device 34 can project out of the surface of the three-dimensional structure. The projection device 34 emits light toward the fourth surface, thereby projecting a fourth image that appropriately overlaps the fourth surface. At least a part of the fourth surface may overlap with at least a part of the first surface. In this case, at least a part of the fourth image may be the same as at least a part of the first image. Alternatively, the fourth surface may not overlap with the first surface. In this case, the fourth image is different from the first image. The same applies to the relationship between the fourth surface and the second surface (the fourth image and the second image) and the relationship between the fourth surface and the third surface (the fourth image and the third image). .

  The stage 40 is a member that can support a three-dimensional structure. The stage 40 includes a support member 401 that supports the three-dimensional structure, and a wall member 402 that is distributed around the support member 401 and protrudes upward from the upper surface of the support member 401. The support member 401 supports a three-dimensional structure. The modeling head 21 supplies the modeling material EL on the support member 401 (or on the layer structure already formed on the support member 401 as will be described later with reference to FIG. 13A). A three-dimensional structure is formed on the support member 401. The generation head 22 generates the modeling material EL from the three-dimensional structure by supplying the solution LQ to the three-dimensional structure supported by the support member 401. The modeling material EL supplied by the modeling head 21 or generated by the generating head 22 is a liquid material, but the wall member 402 prevents the modeling material EL from leaking out of the stage 40. The irradiation device 30 projects an image on the surface of the three-dimensional structure supported by the support member 401.

  The stage 40 is movable by the operation of the moving mechanism 50 connected to the stage 40 via the connecting member 42. The stage 40 is movable with respect to the modeling head 21 and the generation head 22 that are fixed. That is, in the stage 40, the relative positional relationship between the stage 40 and the modeling head 21 and the generation head 22 (more specifically, the stage 40, a material supply port 211 and a liquid supply port 221 described later) is changed. Can be moved to. The stage 40 is movable along each of the X axis direction, the Y axis direction, and the Z axis direction. The stage 40 may further be movable along at least one of the θX direction, the θY direction, and the θZ direction. The stage 40 is movable in the work space SP.

  In order to move the stage 40, the moving mechanism 50 includes a Z guide bar 51, a screw shaft 52, a nut 53, and an actuator 54. As described above, the actuator 54 is housed in the housing space inside the base 11. The Z guide bar 51 is a member for guiding the movement of the stage 40 along the Z-axis direction. Accordingly, the Z guide bar 51 is a member extending along the Z-axis direction. The screw shaft 52 is a member whose surface is threaded. The screw shaft 52 is a member extending along the Z-axis direction. The screw shaft 52 can be rotated along the θZ direction by an actuator 54. The nut 53 is a member formed with a screw thread that is fitted into the screw thread of the screw shaft 52. The nut 53 is fitted into the screw shaft 52 and the Z guide bar 51. When the screw shaft 52 rotates, the nut 53 moves along the screw shaft 52 and the Z guide bar 51 (that is, along the Z-axis direction). Therefore, the screw shaft 52 and the nut 53 function as a slide screw or a ball screw. The stage 40 is connected to the nut 53 via a connecting member 42. Accordingly, the stage 40 also moves along the Z-axis direction in accordance with the movement of the nut 53 along the Z-axis direction. The actuator 40 further moves the Z guide bar 51, the screw shaft 52, and the nut 53 along the XY plane. Therefore, in accordance with the movement of the nut 53 along the XY plane, the stage 40 also moves along the XY plane (that is, the X-axis direction and the Y-axis direction).

The controller 60 controls the 3D printer PR. For example, the controller 60 controls the 3D printer PR so as to perform the modeling process. Specifically, in order to perform the modeling process, the controller 60 controls the actuator 54 so that the stage 40 moves in synchronization with the supply of the modeling material EL by the modeling head 21. Further, in order to perform the modeling process, the controller 60 controls the modeling head 21 so that the modeling head 21 supplies the modeling material EL in synchronization with the movement of the stage 40. For example, the controller 60 controls the 3D printer PR (in particular, the irradiation device 30) so as to perform the projection process. For example, the controller 60 controls the 3D printer PR so as to perform the generation process. In order to perform the generation process, the controller 60 controls the generation head 22 so that the generation head 22 supplies the solution LQ.
(1-2) Configuration of Modeling Material EL and Solution LQ Supply System Next, the configuration of the modeling material EL and the solution LQ supply system will be described with reference to FIG. In FIG. 9, the scales of some members constituting the 3D printer PR are adjusted in order to clearly explain the supply system of the modeling material EL and the solution LQ.

  As shown in FIG. 9, the supply system of the modeling material EL is formed inside some members constituting the 3D printer PR. Specifically, a material tank 111 that stores the modeling material EL is accommodated in the accommodating space inside the base 11. A supply pipe 112 formed inside the base 11 is connected to the material tank 111. A supply pipe 131 formed inside the column 13 is connected to the supply pipe 112. A supply pipe 151 formed inside the beam member 15 is connected to the supply pipe 131. A supply pipe 201 formed inside the print head 20 is connected to the supply pipe 151. The supply pipe 201 communicates with a material supply port 211 formed in the modeling head 21. The modeling material EL stored in the material tank 111 is supplied to the supply pipe 112 by the operation of at least one of a pump and a valve (not shown). The modeling material EL supplied to the supply pipe 112 is supplied to the material supply port 211 via the supply pipes 131, 151 and 201. As a result, a desired amount of modeling material EL is supplied from the material supply port 211 to the work space SP at a desired timing. That is, the modeling head 21 performs material supply processing using the material supply port 211.

  The modeling material EL supplied from the material supply port 211 is dried by gas blown from the gas supply port 212 formed in the modeling head 21 (for example, gas heated to such an extent that the liquid EL3 can be evaporated). That is, the modeling head 21 uses the gas supply port 212 to blow out gas in order to perform the drying process. As a result, a three-dimensional structure is formed.

  The three-dimensional structure modeled by the modeling process is dissolved by the generation process (specifically, the liquid supply process for supplying the solution LQ). In this case, the modeling material EL generated by the generation process is recovered from the plurality of recovery ports 403 formed on the upper surface of the support member 401 of the stage 40. The modeling material EL recovered from the plurality of recovery ports 403 includes a recovery pipe 404 formed inside the stage 40, a recovery pipe 421 formed inside the connecting member 42, and a recovery pipe 531 formed inside the nut 53. The material tank 111 is supplied through a recovery pipe 532 formed between the nut 53 and the base 11 and a recovery pipe 115 formed inside the base 11. As a result, the modeling material EL generated by the generation process can be reused as the modeling material EL used for the modeling process.

Similarly, as shown in FIG. 9, the supply system of the solution LQ is also formed inside some members constituting the 3D printer PR. Specifically, in the storage space inside the base 11, a liquid tank 113 that stores the solution LQ is stored. A supply pipe 114 formed inside the base 11 is connected to the liquid tank 113. A supply pipe 132 formed inside the column 13 is connected to the supply pipe 114. A supply pipe 152 formed inside the beam member 15 is connected to the supply pipe 132. A supply pipe 202 formed inside the print head 20 is connected to the supply pipe 152. The supply pipe 202 communicates with a liquid supply port 221 formed in the generation head 22. The solution LQ supplied to the liquid tank 113 is supplied to the supply pipe 114 by the operation of at least one of a pump and a valve (not shown). The modeling material EL supplied to the supply pipe 114 is supplied to the liquid supply port 221 through the supply pipes 132, 152, and 202. As a result, a desired amount of the solution LQ is supplied from the liquid supply port 221 to the work space SP at a desired timing. That is, the generation head 22 performs a liquid supply process using the liquid supply port 221.
(2) Processing Performed by 3D Printer PR Next, with reference to FIG. 10, the processing performed by the 3D printer PR mainly under the control of the controller 60 (specifically, the above-described modeling processing, generation processing, and projection processing). explain.

  As illustrated in FIG. 10, the controller 60 determines whether or not a modeling instruction that requests to model a three-dimensional structure is input from the user (step S <b> 11). Alternatively, when the 3D printer PR can communicate with an external server via a network, the controller 60 may determine whether or not a modeling instruction is input from the external server.

  As a result of the determination in step S11, when it is determined that a modeling instruction has been input (step S11: Yes), the controller 60 acquires 3D print data (step S12). The 3D print data is data used for modeling a three-dimensional structure. The 3D print data is, for example, 3D model data of a 3D structure. The controller 60 may acquire 3D print data from a storage device (for example, a hard disk or a memory card) that is mounted on the 3D printer PR or detachable from the 3D printer PR. The controller 60 may acquire 3D print data from an external server that can communicate via a network. The controller 60 may generate 3D print data.

  Thereafter, the controller 60 generates control data for controlling the stage 40 and the modeling head 21 based on the 3D print data acquired in step S12 (step S13). Specifically, the controller 60 generates control data capable of controlling the stage 40 and the modeling head 21 so as to model a three-dimensional structure according to the 3D print data.

  The control data includes first control data for controlling the movement mode of the stage 40. Therefore, the controller 60 generates first control data that defines the movement mode of the stage 40 that can form the three-dimensional structure according to the 3D print data. The movement mode of the stage 40 includes at least one of the movement timing of the stage 40, the movement direction of the stage 40, the movement amount of the stage 40, and the movement speed of the stage 40.

  The control data includes second control data for controlling the supply mode of the modeling material EL from the modeling head 21. Therefore, the controller 60 generates the second control data that defines the supply mode of the modeling material EL that can model the three-dimensional structure according to the 3D print data. The supply mode of the modeling material EL includes at least one of the supply timing of the modeling material EL and the supply amount of the modeling material EL.

  Thereafter, the controller 60 controls the stage 40 and the modeling head 21 based on the control data generated in step S13 (step S14). Specifically, the controller 60 controls the stage 40 so that the stage 40 moves in a movement mode defined by the first control data included in the control data (that is, controls the actuator 54 that can move the stage 40). To do). Furthermore, the controller 60 controls the modeling head 21 so that the modeling head 21 supplies the modeling material EL in a supply mode defined by the second control data included in the control data. As a result, a three-dimensional structure is formed on the stage 40 (in other words, in the work space SP).

  Here, a process of modeling a three-dimensional structure by controlling the stage 40 and the modeling head 21 will be described with reference to FIGS. 11 (a) to 14 (b).

  FIG. 11A and FIG. 11B show a left side view and a plan view of the 3D printer when the modeling of the three-dimensional structure is started by controlling the stage 40 and the modeling head 21, respectively. As shown in FIGS. 11A and 11B, when the modeling of the three-dimensional structure is started, the stage 40 is directly above the modeling start position SP (XY) set on the stage 40. It moves along the XY plane so that the modeling head 21 (in particular, the material supply port 211) is positioned. That is, the stage 40 moves so that the material supply position at which the modeling material EL can be supplied by the material supply port 211 (that is, directly below the material supply port 211) coincides with the modeling start position SP (XY). In the example shown in FIGS. 11A and 11B, the modeling start position SP (XY) is the most on the + Y axis side of the surface of the stage 40 (particularly, a region where a three-dimensional structure can be modeled). Matches the region. Furthermore, the stage 40 moves so that the position of the stage 40 along the Z-axis direction coincides with the modeling start position SP (Z) where the stage 40 should be positioned when the modeling of the three-dimensional structure is started. In the example shown in FIGS. 11A and 11B, the modeling start position SP (Z) coincides with the most + Z-axis side region within the range in which the stage 40 can move along the Z-axis direction. To do.

  Thereafter, the stage 40 moves along the XY plane so that the material supply position sequentially moves on the stage 40. As the stage 40 moves, the modeling head 21 supplies the modeling material EL to a desired position on the stage 40. The modeling head 21 further blows out gas from the gas supply port 212 in accordance with the supply of the modeling material EL. As a result, the liquid EL3 constituting the modeling material EL evaporates. For this reason, as shown in FIG.12 (b), several particle | grains EL1 couple | bond relatively firmly through the binding material EL2. Thereafter, as shown in FIGS. 12A and 12B, when the material supply position matches the modeling end position EP (XY) set on the stage 40, the stage 40 is three-dimensional. The formation of the first layer structure constituting the structure is completed. In the example shown in FIGS. 12A and 12B, the modeling end position EP (XY) is the most −Y axis in the surface of the stage 40 (particularly, the region where the three-dimensional structure can be modeled). Match the side area.

  Thereafter, the stage 40 moves by a predetermined amount of movement in the −Z axis direction. Thereafter, the process of moving the stage 40 along the XY plane so that the material supply position moves from the modeling end position EP (XY) toward the modeling start position SP (XY), and the modeling head 21 supplies the modeling material EL. The process and the process which the modeling head 21 blows off gas are performed again. As a result, the second layer structure constituting the three-dimensional structure is formed on the first layer structure. Thereafter, the stage 40 moves by a predetermined amount of movement in the −Z axis direction. Thereafter, a process in which the stage 40 moves along the XY plane so that the material supply position moves from the modeling start position SP (XY) toward the modeling end position EP (XY), and the modeling head 21 supplies the modeling material EL. The process and the process which the modeling head 21 blows off gas are performed again. As a result, the third layer structure constituting the three-dimensional structure is formed on the second layer structure. Thereafter, by repeating the same operation, layer structures constituting a three-dimensional structure are sequentially formed on the stage 40 as shown in FIGS. 13 (a) and 13 (b).

  Thereafter, as shown in FIGS. 14A and 14B, the layer structure is formed until the position of the stage 40 along the Z-axis direction matches the modeling end position EP (Z). In the example shown in FIG. 14A and FIG. 14B, the modeling end position EP (Z) is in the most −Z axis side region in the range in which the stage 40 can move along the Z axis direction. Match. As a result, the modeling of the three-dimensional structure on the stage 40 is completed.

  In FIG. 10 again, after the modeling of the three-dimensional structure is completed, the controller 60 determines whether or not a projection instruction that requests to project an image on the surface of the three-dimensional structure is input from the user ( Step S21). Alternatively, when the 3D printer PR can communicate with an external server via a network, the controller 60 may determine whether or not a projection instruction is input from the external server.

  As a result of the determination in step S21, when it is determined that a projection instruction has been input (step S21: Yes), the controller 60 acquires image data (step S22). The image data is data indicating an image to be projected on the surface of the three-dimensional structure. The image data may indicate a color image or a monochrome image. The image data may be two-dimensional image data or three-dimensional image data. The controller 60 may acquire image data from a storage device (for example, a hard disk or a memory card) that is mounted on the 3D printer PR or detachable from the 3D printer PR. The controller 60 may acquire image data from an external server that can communicate via a network. The controller 60 may generate image data.

  The irradiation device 30 includes four projection devices 31 to 34. For this reason, the controller 60 outputs image data indicating an image projected by the projection device 31, image data indicating an image projected by the projection device 32, image data indicating an image projected by the projection device 33, and projection performed by the projection device 34. Image data indicating an image to be acquired is acquired.

  Certain image data is data indicating an image to be projected on the surface of a three-dimensional structure formed based on certain 3D print data. That is, image data and 3D print data are related to each other in a one-to-one, one-to-many, or many-to-one relationship. For this reason, the image data may be associated with the 3D print data. In this case, the controller 60 may acquire image data associated with the 3D print data acquired in step S12. When there are a plurality of image data associated with the 3D print data, the controller 60 may acquire one of the plurality of image data based on a user instruction or the like.

  Thereafter, the controller 60 performs a conversion process for converting the image data acquired in step S22 based on at least one of the 3D print data acquired in step S12 and the control data generated in step S13 (step S23).

  As described above, 3D print data is data used to form a three-dimensional structure. Therefore, the 3D print data is substantially data indicating the shape of the surface of the three-dimensional structure formed by the modeling process. For this reason, the controller 60 can specify the coordinates of each part of the surface of the three-dimensional structure in the modeling coordinate system in the work space SP (in other words, on the stage 40) based on the 3D print data. On the other hand, since the position of the projection device 31 is known to the controller 60, the controller 60 can specify the position of the projection device 31 in the modeling coordinate system. As a result, the controller 60 can specify the positional relationship between the projection device 31 and the surface of the three-dimensional structure based on the 3D print data. For example, the controller 60 can specify the distance between the projection device 31 and each part of the surface of the three-dimensional structure. For example, the controller 60 can specify an incident angle at which light emitted from the projection device 31 enters each part of the surface of the three-dimensional structure. Based on the identified positional relationship, the controller 60 displays image data (that is, three-dimensional image data) indicating an image (that is, a three-dimensional image) that appropriately overlaps the surface of the three-dimensional structure with the image data acquired in step S22. ) Is converted. The conversion process is a conversion process based on a projection mapping technique. If the image data acquired in step S22 is two-dimensional image data, the conversion process performs a three-dimensional image indicating an image that appropriately overlaps the surface of the three-dimensional structure from the acquired two-dimensional image data. Includes processing to generate data. When the image data acquired in step S22 is three-dimensional image data, the conversion process corrects the acquired three-dimensional image data to indicate a three-dimensional image that appropriately overlaps the surface of the three-dimensional structure. Includes processing to generate image data. The controller 60 performs the same conversion process for image data indicating data to be projected by each of the projection devices 32 to 34.

  On the other hand, as described above, the three-dimensional structure is modeled by the stage 40 moving and the modeling head 21 supplying the modeling material EL. However, depending on the movement accuracy of the stage 40 and the supply accuracy of the modeling head 21, the shape of the surface of the actually modeled three-dimensional structure may not match the shape of the surface of the three-dimensional structure indicated by the 3D print data. There is. Here, as described above, the control data is data capable of controlling the stage 40 and the modeling head 21 so as to model the three-dimensional structure according to the 3D print data. That is, it can be said that the control data is data indicating an actual movement mode of the stage 40 and an actual supply mode of the modeling head 21. Therefore, it can be said that the control data is data that indicates the shape of the surface of the three-dimensional structure formed by the modeling process with higher accuracy. For this reason, the controller 60 performs conversion processing for converting the image data acquired in step S22 into image data indicating an image that appropriately overlaps the surface of the three-dimensional structure based on not only the 3D print data but also the control data. Do. As a result, image data indicating an image that appropriately overlaps the surface of the three-dimensional structure is generated.

  Thereafter, the controller 60 controls the projection devices 31 to 34 such that each of the projection devices 31 to 34 projects the image indicated by the image data generated by the conversion process of step S23 (step S24). As a result, each of the projection devices 31 to 34 projects an image that appropriately overlaps the surface of the three-dimensional structure on the surface of the three-dimensional structure based on the projection mapping technique.

  Here, a three-dimensional structure on which an image is projected will be described with reference to FIGS. 15 to 16. FIG. 15 is a three-dimensional view showing a three-dimensional structure before an image is projected. As described above, each particle EL1 included in the modeling material EL is a white particle. For this reason, the surface of the three-dimensional structure before the image is projected is white. FIG. 15 shows an example in which a three-dimensional structure representing a person is formed.

  On the other hand, FIG. 16 is a three-dimensional view illustrating an example of a three-dimensional structure after an image is projected. Each of the projection devices 31 to 34 projects an image on the surface of the three-dimensional structure by irradiating the three-dimensional structure with light (visible light). The light irradiated to the three-dimensional structure is reflected by the surface of the three-dimensional structure. The light (visible light) reflected from the surface of the three-dimensional structure reaches the retina of the user. As a result, as shown in FIG. 16, the user visually recognizes the three-dimensional structure that is colored on the surface using a virtual color corresponding to the wavelength of light reflected on the surface of the three-dimensional structure. Further, the user visually recognizes the three-dimensional structure having brightness (luminance) corresponding to the intensity of light reflected from the surface of the three-dimensional structure. For example, if the light reflected by the first portion of the surface of the three-dimensional structure is light of the first intensity having a wavelength corresponding to red light, the user is virtually colored in red and A first portion having brightness according to the first intensity is visually recognized. For example, when the light reflected by the second portion of the surface of the three-dimensional structure is light of the second intensity (however, the second intensity is smaller than the first intensity) having a wavelength corresponding to blue light The user visually recognizes the second portion that is virtually colored in blue and has brightness according to the second intensity (that is, relatively dark compared to the first portion). Similarly, when the light reflected by the third portion of the surface of the three-dimensional structure is light of the third intensity having other wavelengths, the user is virtually colored with a color corresponding to the wavelength and A third portion having brightness corresponding to three intensities is visually recognized.

  As described above, the color of the surface of the three-dimensional structure is white. Therefore, the surface of the three-dimensional structure can reflect the light incident on the surface without depending on the wavelength of the light incident on the surface. For this reason, the color of the image which image data shows is the same as the color which a user should visually recognize. In other words, the controller 60 may perform image data conversion processing so that image data indicating an image colored with a color that the user should visually recognize is generated.

  On the other hand, when each particle EL1 included in the modeling material EL is a particle having a color different from white, the color of the surface of the three-dimensional structure is a color different from white. In this case, the surface of the three-dimensional structure may reflect light having a certain wavelength and may not reflect (for example, absorb) light having a certain wavelength depending on the wavelength of light incident on the surface. . For this reason, if the image colored with the color which a user should visually recognize is projected on the surface of a three-dimensional structure as it is, the user was colored with the color different from the color which should originally color a three-dimensional structure. There is a possibility of visually recognizing a three-dimensional structure. For this reason, the controller 60 may perform the above-described conversion process so that the image data is generated based on the reflection characteristics of the three-dimensional structure. Specifically, in the controller 60, based on the reflection characteristics of the three-dimensional structure, an image colored with a wavelength of a color that should be visually recognized by the user is formed by light reflected on the surface of the three-dimensional structure. Conversion processing may be performed so that image data indicating an image capable of realizing the above is generated.

  The intensity of light reflected from the surface of the three-dimensional structure also varies according to the reflection characteristics (for example, reflectance) of the surface of the three-dimensional structure, as is the wavelength of light reflected from the surface of the three-dimensional structure. To do. Therefore, the controller 60 may perform the conversion process so that the image data is generated based on the reflection characteristics of the three-dimensional structure. Specifically, the controller 60 can realize a situation in which an image of brightness that should be visually recognized by the user is formed by light reflected from the surface of the three-dimensional structure, based on the reflection characteristics of the three-dimensional structure. The conversion process may be performed so that image data indicating an image is generated.

  In FIG. 10 again, thereafter, the controller 60 determines whether or not a switching instruction for requesting switching of an image to be projected onto the three-dimensional structure is input from the user (step S25). Alternatively, when the 3D printer PR can communicate with an external server via a network, the controller 60 may determine whether a switching instruction is input from the external server.

  As a result of the determination in step S25, when it is determined that a switching instruction has been input (step S25: Yes), the controller 60 acquires new image data (step S22). Thereafter, the controller 60 performs conversion processing on the newly acquired image data (step S23). Thereafter, the controller 60 controls the projection devices 31 to 34 such that each of the projection devices 31 to 34 projects the image indicated by the newly acquired image data (step S24). As a result, the user visually recognizes the three-dimensional structure that has been colored according to the new image.

  For example, assume that the user is viewing a three-dimensional structure on which an image is projected as shown in FIG. In this case, the user visually recognizes the person wearing the skirt. In this situation, it is assumed that new image data indicating an image of a person wearing pants is acquired. As a result, the three-dimensional structure visually recognized by the user is switched from the three-dimensional structure indicating the person wearing the skirt to the three-dimensional structure indicating the person wearing the pants. That is, the image itself projected on at least a part of the surface of the three-dimensional structure visually recognized by the user changes.

  Alternatively, a situation is assumed in which the user visually recognizes a person wearing a white shirt. In this situation, it is assumed that new image data indicating an image of a person wearing a light blue shirt is acquired. As a result, the three-dimensional structure visually recognized by the user is switched from a three-dimensional structure indicating a person wearing a white shirt to a three-dimensional structure indicating a person wearing a light blue shirt. . That is, the image itself projected onto at least a part of the surface of the three-dimensional structure visually recognized by the user does not change (except for the color of the image), but at least a part of the surface of the three-dimensional structure visually recognized by the user. The virtual color changes.

  Alternatively, a situation is assumed in which the user visually recognizes a person with relatively bright hair. In this situation, it is assumed that new image data indicating an image of a person with relatively dark hair is acquired. As a result, the three-dimensional structure visually recognized by the user is switched from a three-dimensional structure indicating a relatively bright hair person to a three-dimensional structure indicating a relatively dark hair person. That is, although the image itself projected on at least a part of the surface of the three-dimensional structure visually recognized by the user does not change (except for the brightness of the image), at least one of the surfaces of the three-dimensional structure visually recognized by the user. The virtual brightness of the part changes.

  However, the virtual color of at least a part of the surface of the three-dimensional structure visually recognized by the user can be changed by changing the wavelength of light emitted by at least one of the projection devices 31 to 34. Similarly, the virtual brightness of at least a part of the surface of the three-dimensional structure visually recognized by the user can be changed by changing the intensity of light emitted by at least one of the projection devices 31 to 34. Therefore, the controller 60 may change at least one of the wavelength and intensity of light emitted by at least one of the projection devices 31 to 34 instead of switching the image data. For example, the controller 60 may change the wavelength of light applied to the fourth portion so that the virtual color of the fourth portion of the surface of the three-dimensional structure visually recognized by the user changes. For example, the controller 60 may change the intensity of light applied to the fourth portion so that the virtual brightness of the fourth portion of the surface of the three-dimensional structure visually recognized by the user changes.

  On the other hand, as a result of the determination in step S25, if it is determined that the switching instruction has not been input (step S25: No), the controller 60 may not acquire new image data.

  On the other hand, if it is determined that the projection instruction is not input as a result of the determination in step S21 (step S21: No), the controller 60 may not perform the processing from step S22 to step S25. However, even if no projection instruction is input, the controller 60 may perform the processing from step S22 to step S25 after the modeling of the three-dimensional structure is completed. In this case, the controller 60 does not have to perform the process of step S21.

  Thereafter, the controller 60 determines whether or not a generation instruction for requesting generation of the modeling material EL from the three-dimensional structure has been input from the user (step S31). Alternatively, when the 3D printer PR can communicate with an external server via a network, the controller 60 may determine whether a generation instruction is input from the external server.

  As a result of the determination in step S31, when it is determined that a generation instruction has been input (step S31: Yes), the controller 60 controls the generation head 22 to supply the solution LQ (step S32). Since the generation head 22 is disposed above the work space SP, the generation head 22 is positioned above the three-dimensional structure supported by the stage 40. For this reason, the solution LQ supplied by the generation head 22 falls down along the three-dimensional structure. For this reason, the production | generation head 22 can supply the solution LQ substantially to the whole three-dimensional structure by supplying the solution LQ to the three-dimensional structure from above the three-dimensional structure. . As a result of the supply of the solution LQ, the three-dimensional structure formed by the forming process is dissolved. As a result of the dissolution of the three-dimensional structure, the three-dimensional structure substantially disappears from the stage 40. In other words, the three-dimensional structure is substantially removed from the stage 40. A product obtained by dissolving the three-dimensional structure (that is, the modeling material EL) is recovered from the recovery port 403. The modeling material EL recovered from the recovery port 403 can be reused as the modeling material EL for modeling the three-dimensional structure. Therefore, it can be said that the generation process for generating the modeling material EL from the three-dimensional structure substantially includes a restoration process for restoring the modeling material EL from the three-dimensional structure.

  When the generation head 22 does not supply the solution LQ to the entire three-dimensional structure only by supplying the solution LQ to the three-dimensional structure from above the three-dimensional structure, the controller 60 generates the The stage 40 may be controlled so that the stage 40 moves in accordance with the supply of the solution LQ from the head 22. As a result, compared with the case where the stage 40 does not move, the solution LQ is easily supplied to the entire three-dimensional structure.

  After modeling material EL is produced | generated from the three-dimensional structure, the controller 60 performs the process after step S11 again. Therefore, when a modeling instruction is input, the three-dimensional structure is modeled again. In this case, the modeling material EL generated from the three-dimensional structure may be used as the modeling material EL for modeling the three-dimensional structure.

  On the other hand, if it is determined that the generation instruction has not been input as a result of the determination in step S31 (step S31: No), the controller 60 does not perform the process in step S32. In this case, the controller 60 ends the process shown in FIG. Alternatively, the controller 60 may perform the process of step S11 again.

  On the other hand, as a result of the determination in step S11, when it is determined that the modeling instruction is not input (step S11: No), the controller 60 determines whether or not the stage 40 already supports the three-dimensional structure. Is determined (step S41).

  As a result of the determination in step S41, when it is determined that the stage 40 supports the three-dimensional structure (step S41: Yes), the 3D printer PR does not form a new three-dimensional structure. The projection process and the generation process can be performed on the existing three-dimensional structure already supported by the stage 40. Therefore, in this case, the controller 60 performs the processing after step S21. On the other hand, as a result of the determination in step S41, when it is determined that the stage 40 does not support the three-dimensional structure (step S41: No), the 3 controller 60 ends the process shown in FIG. Alternatively, the controller 60 may perform the process of step S11 again.

  As described above, the 3D printer PR of the present embodiment can generate the modeling material EL from the three-dimensional structure modeled using the modeling material EL. Further, the 3D printer PR can model a new three-dimensional structure using the generated modeling material EL. For this reason, compared with the case where modeling material EL is not produced | generated from a three-dimensional structure, the total amount of modeling material EL required in order to model a some three-dimensional structure decreases. Therefore, the cost required for procurement of the modeling material EL is reduced.

  The 3D printer PR of the present embodiment can project an image onto a shaped three-dimensional structure. As a result, the user can visually recognize a three-dimensional structure that is virtually colored on the surface. In particular, since the virtual coloring of the three-dimensional structure is performed by projecting the image, the coloring of the three-dimensional structure can be easily performed by switching the image (or changing the characteristics of the light emitted by the irradiation device 30). It can be changed. That is, it is very easy to redo the coloring of the three-dimensional structure. Therefore, the 3D printer PR can present a three-dimensional structure having various appearances with various colors to the user. The image projected on the surface of the three-dimensional structure may be a still image or a moving image.

  In the 3D printer PR of the present embodiment, the print head 20 does not move. Accordingly, a moving mechanism for moving the print head 20 may not be disposed above the print head 20. Further, a part of the members and devices constituting the 3D printer PR (for example, the controller 60, the moving mechanism 54, and the circulation system) may be another part of the members and devices (for example, the base 11, The column 13 and the beam member 15 are housed inside. For this reason, the external appearance of the 3D printer PR becomes a simple and refined external appearance.

  In the 3D printer PR of the present embodiment, the panel 16 is a transparent member. For this reason, the user can visually recognize the three-dimensional structure supported by the stage 40 appropriately. In addition, since the user can appropriately visually recognize the three-dimensional structure supported by the stage 40, the 3D printer PR can also be used as a display device that displays products. For example, the 3D printer PR can display different products sequentially by repeating the modeling process and the generation process. For example, the 3D printer PR can sequentially display products with different colors by performing a projection process.

  In addition, since the user can appropriately visually recognize the three-dimensional structure supported by the stage 40, the 3D printer PR can also be used as an advertising device that uses the three-dimensional structure formed by the modeling process as an advertising medium. It is. Alternatively, the 3D printer PR can also be used as an advertising device that uses a three-dimensional structure whose surface is virtually colored by projection processing as an advertising medium. In this case, the 3D printer PR may be installed in a public place such as a station or a street. The 3D printer PR may be installed in a private place such as a private house.

  The controller 60 can generate image data indicating an image to be projected by each of the projection devices 31 to 34 based on the control data as well as the 3D print data. For this reason, the controller 60 can generate image data indicating an image that appropriately overlaps the surface of the actually shaped three-dimensional structure.

  The configuration of the 3D printer PR described above (for example, the shape, arrangement position, size, etc. of each member (or each device) constituting the 3D printer PR) is merely an example. Accordingly, at least a part of the configuration of the 3D printer PR may be appropriately modified. Similarly, the processing (for example, processing content, processing flow, processing order, etc.) performed by the 3D printer PR described above is merely an example. Accordingly, at least a part of the processing performed by the 3D printer PR may be appropriately modified. Hereinafter, some modified examples will be described.

  The shape of the base 11 along the XY plane may be a shape different from a triangle (for example, an arbitrary polygon such as a quadrangle, a circle, an ellipse, or the like). The shape of the panel 16 along the XY plane may also be a shape different from a triangle (for example, an arbitrary polygon such as a quadrangle, a circle, an ellipse, or the like). The shape of the base 11 along the XY plane may not be the same as or similar to the shape of the panel 16 along the XY plane.

  The space inside the panel 16 (for example, the work space SP) may not always be visible from the outside of the panel 16. In this case, for example, the panel 16 may be formed using a material capable of changing visibility (for example, a material having a variable transmittance with respect to visible light). The panel 16 may be movable. In this case, for example, the panel 16 may move so that the panel 11 is accommodated in the base 11 during a period in which the panel 16 is unnecessary. Alternatively, the 3D printer PR may not include the panel 16.

  Instead of the wall member 402, the stage 40 may include a support member 401 in which a protruding portion (wall portion) extending upward is formed at the peripheral edge portion. Alternatively, the stage 40 may not include the wall member 402 (or the protrusion formed on the support member 401). The 3D printer PR may include a multi-axis robot arm that can move the stage 40 in addition to or instead of the moving mechanism 50.

  The 3D printer PR may include an arbitrary modeling apparatus capable of performing a modeling process in addition to or instead of the modeling head 21. The 3D printer PR may include an arbitrary generation device capable of performing a generation process in addition to or instead of the generation head 22.

  The modeling head 21 and the generation head 22 may not be adjacent to each other. The 3D printer PR includes a first printer head including the modeling head 21 and a second printer head including the generation head 22 separately from the printer head 20 including both the modeling head 21 and the generation head 22. Also good. The first printer head and the second printer head (or any modeling apparatus and any generation apparatus) may be arranged on separate members. An example in which the first printer head and the second printer head are arranged on separate members corresponds to a first modified example (see FIG. 18) described later. Alternatively, the modeling head 21 and the generation head 22 may be integrated.

  In the above-described embodiment, the print head 20 does not move. However, the print head 20 may be movable. In this case, the 3D printer PR may include another moving mechanism that can move the print head 20. Other moving mechanisms may have the same configuration as the moving mechanism 50 described above. Alternatively, the other moving mechanism may have a configuration different from the moving mechanism 50 described above. Another moving mechanism may be disposed above the print head 20.

  In the above-described embodiment, the modeling process includes a material supply process and a drying process. However, the modeling process may include any process that contributes to modeling the three-dimensional structure using the modeling material EL in addition to or instead of at least one of the material supply process and the drying process. .

  In the drying process, the modeling material EL may be dried so as to solidify all of the modeling material EL supplied by the material supply process. Alternatively, the drying process solidifies a part of the modeling material EL supplied by the material supply process, while the other part of the modeling material EL supplied by the material supply process is not solidified. The EL may be dried. In this case, another part of the modeling material EL that has not been solidified by the drying process may be recovered through the recovery port 403.

  The modeling head 21 does not have to blow out gas from the gas supply port 212 in order to perform the drying process. In this case, the gas supply port 212 may not be formed in the modeling head 21. Even in this case, when the modeling material EL supplied from the modeling head 21 is naturally dried, a three-dimensional structure is modeled. In order to promote natural drying of the modeling material EL, the work space SP may be set in a chamber in which temperature and humidity are appropriately managed.

  In the above-described embodiment, the generation process includes a liquid supply process. However, the generation process may include an arbitrary process that contributes to generating the modeling material EL from the three-dimensional structure in addition to or instead of the liquid supply process. For example, the generation process may include an arbitrary process that can dissolve the three-dimensional structure without supplying the solution LQ. For example, the generation process may include any process capable of decomposing, crushing, dismantling, or destroying the three-dimensional structure. As an example of such an arbitrary process, there is a process of blowing a desired gas to a three-dimensional structure. An example of such an optional process is a process of causing a desired solid to collide with or come into contact with a three-dimensional structure. An example of such an arbitrary process is a process of applying a physical action (for example, applying a physical impact) to the three-dimensional structure. An example of such an optional process is a process of applying a chemical action to a three-dimensional structure (for example, supplying a substance that chemically reacts with the three-dimensional structure). An example of such an arbitrary process is a process of applying a thermal action to the three-dimensional structure (for example, heating or cooling the three-dimensional structure). As an example of such an arbitrary process, an electrical action is applied to the three-dimensional structure (for example, a predetermined voltage is applied to the three-dimensional structure, or the three-dimensional structure is applied to a predetermined electric field space. Process). As an example of such an arbitrary process, there is a process of applying a magnetic action to the three-dimensional structure (for example, arranging the three-dimensional structure in a predetermined magnetic field space). As an example of such an arbitrary process, a process of applying an optical action to a three-dimensional structure (for example, irradiating light of a predetermined wavelength (or arbitrary electromagnetic wave) having a predetermined intensity) is given. It is done.

  In the embodiment described above, the generation process (liquid supply process) is performed when a generation instruction that requests generation of the modeling material EL from the three-dimensional structure is input. On the other hand, as described above, the three-dimensional structure is substantially eliminated or removed from the stage 40 as a result of the generation head 22 supplying the solution LQ. For this reason, instead of the generation instruction, the generation process (liquid supply process) may be performed when an instruction for requesting the disappearance or removal of the three-dimensional structure from the stage 40 is input. Alternatively, as described above, considering that the generation process may include an arbitrary process capable of dissolving, decomposing, crushing, dismantling, or destroying the three-dimensional structure, instead of the generation instruction, The generation process (liquid supply process) may be performed when an instruction requesting dissolution, decomposition, pulverization, disassembly, or destruction of the three-dimensional structure is input.

  In the embodiment described above, the solution LQ is the same as the liquid EL3 included in the modeling material EL. However, the solution LQ may not be the same as the liquid EL3 included in the modeling material EL. In this case, a product generated by the liquid supply process (that is, a mixture of the plurality of particles EL1, the binding material EL2, and the solution LQ) is different from the modeling material EL. In this case, if an addition process for removing the solution LQ and adding the liquid LQ is performed on the product generated by the liquid supply process, the modeling material EL is generated from the three-dimensional structure. There is no change. That is, the liquid supply process is not a process for directly generating the modeling material EL from the three-dimensional structure, but an intermediate (that is, the above-described mixture) used to generate the modeling material EL from the three-dimensional structure. Corresponds to the process of generating Considering that the modeling material EL can be generated from the intermediate, the liquid supply process, which is a process for generating the intermediate from the three-dimensional structure, is a generation process for generating the modeling material EL from the three-dimensional structure. It is still part of For this reason, even when the dissolution liquid EL is not the same as the liquid EL3, the liquid supply process is still a generation process for generating the modeling material EL from the three-dimensional structure.

  As shown in FIG. 17, a material regeneration processing unit 116 may be disposed upstream of the material tank 111. The material regeneration processing unit 116 performs a predetermined process on the recovered material (that is, the mixture of the plurality of particles EL1, the binding material EL2, and the solution LQ) recovered from the recovery port 403 to generate the modeling material EL ( That is, play). The process performed by the material regeneration processing unit 116 may include, for example, a process of removing (for example, discarding or vaporizing) at least a part of the solution LQ contained in the recovered material. As described above, when the solution LQ and the liquid EL3 are the same, the material regeneration processing unit 116 regenerates the modeling material EL having a viscosity suitable for modeling by removing a part of the solution LQ. The regenerated modeling material EL can be supplied to the material tank 111. In addition, the material regeneration processing unit 116 may perform a cleaning process on a material (for example, the particle EL1) included in the collected material. Further, the material regeneration processing unit 116 may perform addition processing of materials (particle EL1, binding material EL2, etc.). It should be noted that at least a part of the recovered material recovered from the recovery port 403 may be discarded.

  The temperature of the solution LQ supplied from the liquid supply port 221 may be the same as the temperature of the modeling material EL (particularly, the liquid EL3) supplied from the material supply port 211. The temperature of the solution LQ supplied from the liquid supply port 221 may not be the same as the temperature of the modeling material EL (particularly, the liquid EL3) supplied from the material supply port 211. When the temperature of the dissolution liquid LQ is not the same as the temperature of the modeling material EL, the generation process is a product generated by the liquid supply process (that is, a mixture of a plurality of particles EL1, the binding material EL2, and the dissolution liquid LQ). The process of adjusting the temperature may be included. In this case, the product generated by the liquid supply process may be stored in the material tank 111 after the temperature is adjusted.

  In the embodiment described above, the modeling process and the generation process do not change the state of the particle EL. However, at least one of the modeling process and the generation process may include a process of changing the state of the particle EL. In this case, at least one of the modeling process and the generation process may include a process of returning the changed state of the particle EL to the original state.

  In addition, not only when the product produced | generated by the liquid supply process differs from modeling material EL, but also when the product produced | generated by arbitrary production | generation processes differs from modeling material EL, it is modeling material from the said product. As long as the EL can be generated, the generation process is still a generation process for generating the modeling material EL from the three-dimensional structure. However, when the product generated by the arbitrary generation process is different from the modeling material EL, the 3D printer PR uses another device for generating the modeling material EL from the product (for example, the above-described solution LQ For example, an addition device for adding liquid EL3, or the like. In this case, the generation process may include a process performed by another device.

  In the embodiment described above, the solution LQ is supplied from the liquid supply port 221. However, the solution LQ may be supplied from the material supply port 211. In this case, the 3D printer PR may not include at least a part of the supply pipe 114, the supply pipe 132, the supply pipe 152, the supply pipe 202, and the liquid supply port 221.

  The flowchart illustrated in FIG. 10 illustrates an example in which the 3D printer PR performs the generation process after completing the modeling of the three-dimensional structure. However, the 3D printer PR may perform the generation process before the modeling of the three-dimensional structure is completed. That is, the 3D printer PR may perform a process of eliminating or removing the three-dimensional structure in the middle of the modeling from the stage 40 (support member 401) before the modeling of the three-dimensional structure is completed. That is, the 3D printer PR may generate the modeling material EL from the incomplete three-dimensional structure. Even in this case, the 3D printer PR may generate the modeling material EL from the incomplete three-dimensional structure as in the case of generating the modeling material EL from the completed three-dimensional structure.

  In the embodiment described above, the generation head 22 supplies the solution LQ so as to dissolve the entire three-dimensional structure supported by the stage 40. However, the generation head 22 supplies the solution LQ so as to dissolve a part of the three-dimensional structure supported by the stage 40 while not dissolving the other part of the three-dimensional structure supported by the stage 40. May be. In this case, the controller 60 is configured so that the solution LQ is supplied to the portion to be dissolved in the three-dimensional structure, while the solution LQ is not supplied to the portion to be not dissolved in the three-dimensional structure. 40 and the generation head 22 may be controlled. Further, when controlling the stage 40 and the generation head 22, the controller 60 may control the stage 40 and the generation head 22 based on control data for controlling the stage 40 and the modeling head 21. This is because the control data is data that can control the stage 40 and the modeling head 21 so that a desired portion of the three-dimensional structure is positioned directly below the modeling head 21. For this reason, considering that the positional relationship between the modeling head 21 and the generation head 22 is fixed, the control data is substantially the desired portion of the three-dimensional structure of the generation head 22. This is because the data can control the stage 40 and the modeling head 21 so as to be located immediately below (that is, the solution LQ is supplied to a desired portion of the three-dimensional structure). Even when the generating head 22 supplies the dissolving liquid LQ so as to dissolve the entire three-dimensional structure supported by the stage 40, the controller 60 uses control data for controlling the stage 40 and the modeling head 21. Based on this, the stage 40 and the generation head 22 may be controlled.

  The modeling material EL may not include at least one of the plurality of particles EL1, the binding material EL2, and the liquid EL3. The modeling material EL may include other materials in addition to or instead of at least one of the plurality of particles EL1, the binding material EL2, and the liquid EL3. Each particle EL1 may not be a white particle.

  For example, the modeling material EL may be water. In this case, the modeling head 21 may perform a process of supplying water to the work space SP and a process of cooling the water to such an extent that the water is frozen as the modeling process. As a result, a three-dimensional structure composed of ice is formed. On the other hand, the production | generation head 22 may perform the process which heats the three-dimensional structure comprised from ice as a production | generation process. As a result, the ice constituting the three-dimensional structure melts. That is, water that is the modeling material EL is generated from the three-dimensional structure.

  The modeling material EL may not be a liquid material. The modeling material EL may be a solid state material. For example, when the 3D printer PR uses the hot melt lamination method, the modeling material EL may be a solid state material. In this case, the modeling head 21 supplies the modeling material EL melted by heating. The modeling material EL supplied by the modeling head 21 is solidified by being cooled. Even in this case, the generation head 22 may perform a generation process on a three-dimensional structure including the solidified modeling material EL. For example, the production | generation head 22 may perform the process which heats the three-dimensional structure comprised from solidified modeling material EL as a production | generation process. As a result, the generation head 22 can generate a liquefied (or gelled) modeling material EL. As described above, even if the modeling material EL is a solid material, the 3D printer PR can model a three-dimensional structure using the modeling material EL, and generates the modeling material EL from the three-dimensional structure. Is possible.

  At least one of the plurality of recovery ports 403 may not be formed on the upper surface of the support member 401 of the stage 40. For example, at least one of the plurality of recovery ports 403 may be formed on the upper surface of the base 11. For example, at least one of the plurality of recovery ports 403 may be formed on an arbitrary member supported by the base 11. For example, at least one of the plurality of recovery ports 403 may be formed on an arbitrary member included in the 3D printer PR.

  At least a part of the supply system of the modeling material EL may not be formed inside some members constituting the 3D printer PR. That is, at least a part of the supply system of the modeling material EL may be visible as the appearance of the 3D printer PR. Similarly, at least a part of the supply system of the solution LQ may not be formed inside a part of members constituting the 3D printer PR. That is, at least a part of the supply system of the solution LQ may be visible as the appearance of the 3D printer PR. In the example shown in FIG. 9, the collection tube 532 is not formed inside some members constituting the 3D printer PR. Of course, the collection tube 532 may also be formed inside some members constituting the 3D printer PR.

  In the embodiment described above, a part of the supply system of the modeling material EL and the solution LQ is formed inside the support column 13 and the beam member 15. However, a part of the supply system of the modeling material EL and the solution LQ may be formed on the column 12 and the beam member 14 in addition to or instead of the column 13 and the beam member 15. For example, a supply pipe (for example, a supply pipe connected to the supply pipe 112) capable of supplying the modeling material EL may be formed inside the support column 12. For example, a supply pipe (for example, a supply pipe connected to the supply pipe 114) capable of supplying the solution LQ may be formed inside the support column 12. For example, a supply pipe (for example, a supply pipe connected to the supply pipe 201) that can supply the modeling material EL may be formed inside the beam member 14. For example, a supply pipe (for example, a supply pipe connected to the supply pipe 202) that can supply the solution LQ may be formed inside the beam member 14.

  At least two of the plurality of projection devices 31 to 34 may project the same image onto the same portion of the surface of the three-dimensional structure. At least two of the plurality of projection devices 31 to 34 may project different images onto the same portion of the surface of the three-dimensional structure. The irradiation device 30 may include a single projection device. At least one of the projection devices 31 to 34 may be attached to a member different from the columns 12 and 13.

  The controller 60 may not convert the image data based on the 3D print data. The controller 60 may not convert the image data based on the control data. In this case, the controller 60 may acquire image data generated in advance so as to show an image appropriately overlapping the surface of the three-dimensional structure.

  In the embodiment described above, the light irradiated to the three-dimensional structure from each of the projection devices 31 to 34 is reflected on the surface of the three-dimensional structure. However, the light irradiated to the three-dimensional structure from each of the projection devices 31 to 34 may be reflected inside the three-dimensional structure. In this case, the user visually recognizes the three-dimensional structure that is virtually colored on the surface according to the wavelength and intensity of light reflected inside the three-dimensional structure. Alternatively, the light irradiated to the three-dimensional structure from each of the projection devices 31 to 34 may be scattered on the surface or inside of the three-dimensional structure. In this case, the user visually recognizes the three-dimensional structure that is virtually colored on the surface according to the wavelength and intensity of light scattered inside or on the surface of the three-dimensional structure. Alternatively, the light irradiated to the three-dimensional structure from each of the projection devices 31 to 34 may pass through the inside of the three-dimensional structure. In this case, the user visually recognizes the three-dimensional structure that is virtually colored on the surface according to the wavelength and intensity of light transmitted through the inside of the three-dimensional structure.

  In the embodiment described above, the irradiation device 30 includes the projection devices 31 to 34 that irradiate the three-dimensional structure with light (that is, project an image). However, the irradiation device 30 may irradiate the three-dimensional structure with electromagnetic waves having an arbitrary wavelength in addition to or instead of including the projection devices 31 to 34. The electromagnetic wave may be at least one of ultraviolet rays, X-rays, infrared rays, and microwaves, for example. Even when an arbitrary electromagnetic wave is irradiated to the three-dimensional structure, as long as the three-dimensional structure is virtually colored due to the irradiation of the electromagnetic wave, the user is virtually colored on the surface. The three-dimensional structure can be visually recognized. For example, when the modeling material forming the three-dimensional structure includes a light emitting material that emits light due to the irradiation of electromagnetic waves, the three-dimensional structure irradiated with the electromagnetic waves has characteristics of the irradiated electromagnetic waves. In addition, light is emitted in a color corresponding to at least one of the characteristics of the light emitting material. Or when the photosensitive material is apply | coated to the surface of a three-dimensional structure, the photosensitive material irradiated with electromagnetic waves is exposed to the electromagnetic waves of the wavelength according to the characteristic of the photosensitive material. As a result, the three-dimensional structure with the photosensitive material applied on the surface becomes a three-dimensional structure with virtual coloring on the surface.

  In the embodiment described above, the projection image is switched when the switching support is input (step S25 in FIG. 10). However, the projected image may be switched even when the switching support is not input. In this case, the controller 60 may acquire new image data each time the projection image is switched. Alternatively, the controller 60 may acquire image data (for example, two or more image data) that can switch the projection image when it is determined that the projection instruction is input.

While the 3D printer PR performs one of the generation process and the projection process, the other of the generation process and the projection process may not be performed. When the 3D printer PR does not perform the generation process, the 3D printer PR uses the members and devices for performing the generation process (for example, the generation head 22 including the liquid supply port 221, the solution tank 112, the supply pipe 114, the supply The pipe 132, the supply pipe 152, and the supply pipe 202) may not be provided. When the 3D printer PR does not perform the generation process, the 3D printer PR uses the members and devices (for example, the recovery port 403, the recovery pipe 404, the recovery pipe 421, and the like) for recovering the modeling material EL generated by the generation process. The collection tube 531, the collection tube 532, and the collection tube 115) may not be provided. When the 3D printer PR does not perform the projection process, the 3D printer PR may not include a member and an apparatus (for example, the irradiation device 30 including the projection apparatuses 31 to 34) for performing the projection process.
(3) Modification of 3D Printer PR Hereinafter, a modification of the 3D printer PR will be described. In addition, about the member or apparatus same as the member or apparatus with which 3D printer PR mentioned above is provided, the detailed description is abbreviate | omitted by attaching | subjecting the same referential mark.
(3-1) 3D Printer PRa of First Modification
A 3D printer PRa of a first modification will be described with reference to FIG. As shown in FIG. 18, the 3D printer PRa of the first modified example is different from the above-described 3D printer PR in that the print head 20 a does not include the generation head 22. Further, the 3D printer PRa of the first modification is different from the 3D printer PR described above in that a liquid supply port 221a capable of supplying the solution LQ is formed on the upper surface of the support member 401 of the stage 40a. The configurations of other members and devices of the 3D printer PRa may be the same as the configurations of other members and devices of the 3D printer PR.

  In the first modification, the liquid supply process is performed using the liquid supply port 221a. That is, in the first modification, the liquid supply process corresponds to a process of supplying the solution LQ onto the support member 401 from the liquid supply port 221a. Here, the support member 401 supports the three-dimensional structure below the three-dimensional structure. For this reason, when the solution LQ is supplied from the liquid supply port 221a, a portion of the three-dimensional structure that is in contact with the support member 401 (in other words, is in contact with the solution LQ supplied onto the support member 401). Part) dissolves. That is, the lower part of the three-dimensional structure is dissolved. With the dissolution of the lower part of the three-dimensional structure, the three-dimensional structure gradually collapses downward. As a result, a portion of the three-dimensional structure that has not yet dissolved comes into contact with the solution LQ. Therefore, as a result, the entire three-dimensional structure is dissolved.

The 3D printer PRa of the first modified example can enjoy the same effects as the effects that the 3D printer PR described above can enjoy. Further, in the 3D printer PRa of the first modification, the solution LQ is supplied onto the stage 40 (support member 401) that supports the three-dimensional structure. For this reason, even if the stage 40 does not move in accordance with the supply of the solution LQ during the generation process, the entire three-dimensional structure is easily dissolved. Alternatively, even if the liquid supply port 221a does not supply the solution LQ at an appropriate timing according to the movement of the stage 40 (that is, even if the liquid supply port 221a supplies the solution LQ at an arbitrary timing), 3 The whole dimensional structure is easily dissolved. Therefore, the processing load of the controller 60 accompanying the movement of the stage 40 and the supply of the solution LQ is reduced.
(3-2) 3D Printer PRb of Second Modification
A 3D printer PRb of a second modification will be described with reference to FIG. The 3D printer PR described above performs a conversion process for converting the image data based on the control data in order to project an appropriately overlapping image on the surface of the three-dimensional structure. On the other hand, the 3D printer PRb of the second modified example is based on the control data in addition to or instead of performing the conversion process in order to project an image that more appropriately overlaps the surface of the three-dimensional structure. It differs from the 3D printer PR described above in that it controls at least one of 30 and stage 40. Other configurations and processes of the 3D printer PRb may be the same as other configurations and processes of the 3D printer PR.

  Specifically, the controller 60 may move the stage 40 so that the images projected by the irradiation device 30 appropriately overlap the surface of the three-dimensional structure. For example, the controller 60 may move the stage 40 along at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction. That is, the controller 60 may control the arrangement position of the stage 40. For example, the controller 60 may move the stage 40 along at least one of the θX direction, the θY direction, and the θZ direction. That is, the controller 60 may control the arrangement angle of the stage 40. When at least one of the arrangement position and the arrangement angle of the stage 40 changes, the positional relationship between each of the projection devices 31 to 34 included in the irradiation device 30 and the surface of the three-dimensional structure changes. For this reason, the controller 60 can realize a state in which the image projected by the irradiation device 30 appropriately overlaps the surface of the three-dimensional structure by controlling at least one of the arrangement position and the arrangement angle of the stage 40. .

  Alternatively, the controller 60 may move at least one of the projection devices 31 to 34 included in the irradiation device 30. For example, the controller 60 may move at least one of the projection devices 31 to 34 along at least one of the X-axis direction, the Y-axis direction, and the Z-axis direction. That is, the controller 60 may control at least one arrangement position of the projection devices 31 to 34. For example, the controller 60 may move at least one of the projection devices 31 to 34 along at least one of the θX direction, the θY direction, and the θZ direction. That is, the controller 60 may control the arrangement angle of at least one of the projection devices 31 to 34. When at least one of the arrangement position and the arrangement angle of at least one of the projection devices 31 to 34 is changed, between at least one of the projection devices 31 to 34 included in the irradiation device 30 and the surface of the three-dimensional structure. The positional relationship of changes. For this reason, the controller 60 controls at least one of the arrangement position and the arrangement angle of at least one of the projection apparatuses 31 to 34 so that the image projected by the irradiation apparatus 30 is more appropriate for the surface of the three-dimensional structure. It is possible to realize a state of overlapping.

  In order to control at least one of the arrangement position and the arrangement angle of at least one of the projection apparatuses 31 to 34, the 3D printer PRb can move the projection apparatus 31 as shown in FIG. At least one of a mechanism 51b, a moving mechanism 52b capable of moving the projection device 32, a moving mechanism 53b capable of moving the projection device 33, and a moving mechanism 54b capable of moving the projection device 34. Is further provided. Each of the moving mechanisms 51b to 54b may be arranged inside a part of the members constituting the 3D printer PR (for example, the base 11, the support column 12, the support column 13, etc.).

The 3D printer PRb of the second modified example can enjoy the same effects as the effects that the 3D printer PR described above can enjoy.
(3-3) 3D Printer PRc of Third Modification
With reference to FIG. 20, a 3D printer PRc of a third modification will be described. The 3D printer PR described above performs conversion processing for converting image data based on the control data. On the other hand, the 3D printer PRc of the third modified example is different from the above-described 3D printer PR in that the position of the stage 40 during the period in which the modeling process is performed is measured. Further, the 3D printer PRc differs from the above-described 3D printer PR in that it performs conversion processing for converting image data based on the measured position in addition to or instead of based on the control data. Other configurations and processes of the 3D printer PRc may be the same as other configurations and processes of the 3D printer PR.

  In order to measure the position of the stage 40, the 3D printer PRc includes a position measuring device 70c as shown in FIG. In FIG. 20, for convenience of explanation, the position measuring device 70 c is illustrated in the accommodation space inside the base 11. However, at least a part of the position measuring device 70 c may not be confiscated in the accommodation space inside the base 11. For example, the position measuring device 70c may be arranged around the work space SP or around the stage 40.

  The position measurement device 70c may include a laser interferometer, for example. The laser interferometer includes a movable mirror disposed on the stage 40 and a laser light source that irradiates laser light toward the movable mirror. The laser interferometer can measure the position of the stage 40 along the direction in which the movable mirror and the laser light source are arranged. For this reason, when the position measuring device 70c includes a laser interferometer, the position measuring device 70c includes a laser interferometer including a moving mirror and a laser light source arranged along the X-axis direction, and a Y-axis direction. You may provide the laser interferometer provided with a moving mirror and a laser light source arranged in a line, and the laser interferometer provided with the moving mirror and laser light source arranged along the Z-axis direction.

  The position measuring device 70c may include, for example, an encoder (for example, a linear encoder). The encoder includes a scale disposed on the stage 40 and engraved with a scale, and an optical head that irradiates the scale with light and detects light reflected by the scale. The encoder can measure the position of the stage 40 along the direction in which the scale is engraved on the scale. For this reason, when the position measuring device 70c includes an encoder, the position measuring device 70c includes an encoder including a scale in which scales arranged along the X-axis direction are engraved, and a scale aligned along the Y-axis direction. An encoder including an engraved scale and an encoder including a scale engraved with scales along the Z-axis direction may be provided.

  The measurement result of the position measuring device 70c shows the actual movement mode of the stage 40 during the period in which the modeling process is performed. Therefore, it can be said that the measurement result of the position measuring device 70c is data that indicates the shape of the surface of the three-dimensional structure formed by the modeling process with higher accuracy. Because, depending on the movement accuracy of the stage 40, the stage 40 may not move faithfully in the movement mode according to the control data. As a result, the shape of the surface of the actually shaped three-dimensional structure is This is because the shape of the surface of the three-dimensional structure indicated by the 3D print data and the control data may not match. Therefore, the controller 60 performs conversion processing for converting the image data into image data indicating an image that appropriately overlaps the surface of the three-dimensional structure, based on the measurement result of the position measurement device 70c. As a result, image data indicating an image that appropriately overlaps the surface of the three-dimensional structure is generated. For this reason, the 3D printer PRc of the third modified example can enjoy the same effects as the effects that the 3D printer PR can enjoy.

  Note that in the third modification, the stage 40 moves during the period in which the modeling process is performed, so the position measuring device 70c measures the position of the stage 40. However, since the modeling head 21 (material supply port 211) does not move, it can be said that the position of the stage 40 indirectly indicates the position of the modeling head 21. Alternatively, it can be said that the position of the stage 40 indirectly indicates the relative positional relationship between the stage 40 and the modeling head 21. Therefore, the position measuring device 70 c is substantially at least one of the position of the modeling head 21 and the relative positional relationship between the stage 40 and the modeling head 21 in addition to or instead of the position of the stage 40. It can be said that it measures. However, when the modeling head 21 moves during the period in which the modeling process is performed, the position measuring device 70c may measure the position of the modeling head.

Also in the third modification, similarly to the second modification, the controller 60 performs the irradiation device 30 in addition to or instead of performing the conversion process for converting the image data based on the measurement result of the position measurement device 70c. And at least one of the stages 40 may be controlled.
(3-4) 3D Printer PRd of Fourth Modification
A 3D printer PRd according to a fourth modification will be described with reference to FIG. The 3D printer PR described above performs conversion processing for converting image data based on the control data. On the other hand, the 3D printer PRd of the fourth modification example shows the actual supply timing of the modeling material EL during the period in which the modeling process is performed (that is, the timing at which the material supply port 211 actually supplies the modeling material EL). It differs from the 3D printer PR described above in that it measures. Further, the 3D printer PRd is different from the 3D printer PR described above in that it performs conversion processing for converting image data based on the measured supply timing in addition to or instead of based on the control data. Other configurations and processes of the 3D printer PRd may be the same as other configurations and processes of the 3D printer PR.

  In order to measure the supply timing, the 3D printer PRd includes a timing measuring device 70d as shown in FIG. FIG. 21 illustrates a diagram in which the timing measurement device 70d is taken into the accommodation space inside the base 11 for convenience of explanation. However, at least a part of the timing measurement device 70d may not be confiscated in the accommodation space inside the base 11. For example, the timing measurement device 70d may be arranged around the work space SP or around the print head 20. For example, the timing measurement device 70d may be disposed on other members (for example, the beam members 14 and 15) that constitute the 3D printer PR. For example, the timing measuring device 70d may be disposed inside other members (for example, the beam members 14 and 15) that constitute the 3D printer PR.

  The timing measuring device 70d includes, for example, a light source that emits light directly below the material supply port 211 (or a space through which the modeling material EL passes between the material supply port 211 and the stage 40), and the material supply port 211. And a light receiving element that detects light that has passed directly under the light. When the material supply port 211 supplies the modeling material EL in a state where the light source emits light (that is, a state where light from the light source passes under the material supply port 211), the light source is emitted. The light reaches the light receiving element after passing through the modeling material EL. Alternatively, the light emitted from the light source is blocked by the modeling material EL and does not reach the light receiving element. On the other hand, when the material supply port 211 does not supply the modeling material EL in a state where the light source emits light, the light emitted from the light source does not pass through the modeling material EL or by the modeling material EL. The light reaches the light receiving element without being shielded from light. Therefore, when the material supply port 211 supplies the modeling material EL while the light source emits light, the light receiving element receives light compared to the case where the material supply port 211 does not supply the modeling material EL. The intensity of the light is weakened. For this reason, supply timing can be specified from the measurement result (light intensity) of the timing measuring device 70d.

  The measurement result of the timing measuring device 70d indicates the actual supply timing of the modeling material during the period in which the modeling process is performed. Therefore, it can be said that the measurement result of the timing measuring device 70d is data that indicates the shape of the surface of the three-dimensional structure formed by the modeling process with higher accuracy. This is because, depending on the supply accuracy of the modeling head 21, the modeling head 21 may not supply the modeling material EL faithfully to the supply mode according to the control data. As a result, the three-dimensional structure actually modeled may not be supplied. The surface shape may not match the surface shape of the three-dimensional structure indicated by the 3D print data and the control data. For this reason, the controller 60 performs conversion processing for converting the image data into image data indicating an image that appropriately overlaps the surface of the three-dimensional structure based on the measurement result of the timing measurement device 70d. As a result, image data indicating an image that appropriately overlaps the surface of the three-dimensional structure is generated. For this reason, the 3D printer PRd of the fourth modified example can enjoy the same effects as the effects that the 3D printer PR can enjoy.

Also in the fourth modification, similarly to the second modification, the controller 60 performs the irradiation device 30 in addition to or instead of performing the conversion process for converting the image data based on the measurement result of the timing measurement device 70d. And at least one of the stages 40 may be controlled. In addition to the timing measurement device 70d, the 3D printer PRd may include a position measurement device 70c according to a third modification. When the position measuring device 70c is provided, the controller 60 uses the measurement result of the timing measuring device 70d (that is, the supply timing of the modeling material EL) and the measurement result of the position measuring device 70c (that is, the position of the stage 40). , Data indicating the shape of the surface of the three-dimensional structure with high accuracy may be acquired. Furthermore, the controller 60 may control at least one of the irradiation apparatus 30 and the stage 40 in addition to or instead of performing the conversion process for converting the image data based on the acquired data.
(3-5) 3D printer PRE of the fifth modification
With reference to FIG. 22, a 3D printer PRE of a fifth modification will be described. The 3D printer PRe of the fifth modification is different from the 3D printer PR described above in that it further includes a camera 70e. Other configurations and processes of the 3D printer PRe may be the same as other configurations and processes of the 3D printer PR.

  The camera 70e images at least a part of the 3D printer PR. For example, the camera 70e may image at least a part of the members and devices that constitute the 3D printer PR. For example, the camera 70e may image at least a part of the work space SP. The 3D printer PRe may include a plurality of cameras 70e. Further, the camera 70e may be movable.

  The camera 70e may image at least a part of the stage 40. In this case, the controller 60 can measure the position of the stage 40 by analyzing the imaging result of the camera 70e. For this reason, when the camera 70e images at least a part of the stage 40 during the period during which the modeling process is performed, the controller 60 measures the position of the stage 40 during the period during which the modeling process is performed. be able to. That is, the camera 70e can function substantially together with the controller 60 as a specific example of the position measuring device 70c of the third modified example. In this case, the 3D printer PRe may perform processing similar to the processing performed by the 3D printer PRc of the third modified example. That is, the 3D printer PRE may convert the image data based on the imaging result of the camera 70e so that an image that appropriately overlaps the surface of the three-dimensional structure is projected (or the irradiation device 30 and the stage). 40 may control at least one of 40).

  The camera 70e may image the material supply port 211. The camera 70e may image a space immediately below the material supply port 211. In this case, the controller 60 can measure or detect the timing at which the material supply port 211 actually supplies the modeling material EL by analyzing the imaging result of the camera 70e. For this reason, when the camera 70e images the material supply port 211 or the like during the period in which the modeling process is performed, the controller 60 determines that the material supply port 211 is in the modeling material EL during the period in which the modeling process is performed. Can be measured. That is, the camera 70e can function substantially together with the controller 60 as a specific example of the timing measurement device 70d of the fourth modified example. In this case, the 3D printer PRe may perform the same process as the process performed by the 3D printer PRd of the fourth modified example. That is, the 3D printer PRE may convert the image data based on the imaging result of the camera 70e so that an image that appropriately overlaps the surface of the three-dimensional structure is projected (or the irradiation device 30 and the stage). 40 may control at least one of 40).

  The camera 70e may image at least a part of the three-dimensional structure. In this case, the controller 60 can measure the shape of the surface of the three-dimensional structure by analyzing the imaging result of the camera 70e. For example, the camera 70e may capture at least a part of the three-dimensional structure on which the image is projected by the irradiation device 30. For example, in a situation where a test pattern (for example, a lattice pattern) is projected on the surface of the three-dimensional structure by the irradiation device 30 (or by another device), the camera 70e is at least of the three-dimensional structure. A part may be imaged. The controller 60 can specify the shape of the test pattern from the imaging result of the camera 70e, and can measure the shape of the surface of the three-dimensional structure based on the specified shape of the test pattern. In this case, the 3D printer PRe may convert the image data based on the measured shape of the surface of the three-dimensional structure so that an image that appropriately overlaps the surface of the three-dimensional structure is projected. (Alternatively, at least one of the irradiation device 30 and the stage 40 may be controlled).

  In the example described above, the imaging result of the camera 70e is used to project an image that more appropriately overlaps the surface of the three-dimensional structure. However, the imaging result of the camera 70e may be used for other purposes. For example, the imaging result of the camera 70e may be used for failure determination of members and devices that constitute the 3D printer PR. Specifically, for example, when the camera 70e is imaging at least a part of the stage 40, the controller 60 determines whether or not the stage 40 is appropriately moved based on the imaging result of the camera 70e ( Alternatively, it may be determined whether or not the stage 40 has failed. For example, when the camera 70e is imaging the material supply port 211, the controller 60 determines whether or not the material supply port 211 appropriately supplies the modeling material EL based on the imaging result of the camera 70e (or Or whether the material supply port 211 or the modeling head 21 is out of order. For example, when the camera 70e is capturing an image of the liquid supply port 221, the controller 60 determines whether or not the liquid supply port 221 is appropriately supplying the solution LQ based on the imaging result of the camera 70e (or Whether or not the liquid supply port 221 or the generation head 22 is out of order may be determined.

  As shown in FIG. 23, the 3D printer PR may be connectable to a user terminal UT owned by the user of the 3D printer PR. The user terminal UT is a device that can be operated by the user. An example of the user terminal UT is a mobile phone, a tablet terminal, or a personal computer. The user terminal UT and the 3D printer PR can be connected via the communication network NET1. The communication network NET1 may include a wired communication network (for example, an Internet network, a public line network, a dedicated line network, a wired LAN, or the like). The communication network NET1 may include a wireless communication network (for example, a mobile communication network, a wireless LAN, or a Bluetooth (registered trademark) network). The 3D printer PR may be capable of bidirectional communication with the user terminal UT via the communication network NET1, or may be capable of one-way communication. The 3D printer PR may be controllable by the user terminal UT, for example. For example, the 3D printer PR may be controlled by the user terminal UT so as to perform the above-described modeling process.
