Abstract

PROBLEM TO BE SOLVED: To improve a preparing function when an object article is formed by a lamination molding (forming) method. SOLUTION: A material feeding section (ink jet head) 1 and a promoting factor feeding means 2 are two-dimensionally movably supported respectively by a second stage 25 and a first stage 22. In this case, the material feeding section discharges a material M to constitute the object article. The promoting factor feeding means 2 feeds a promoting factor F to promote a phase transformation of the discharged material M. At the same time, the material feeding section 1 and the promoting factor feeding means 2 are rotatably supported by rotating mechanisms 24 and 21. Thus, the irradiation of the material M and the promoting factor F is made possible to a forming surface at an optional angle, and an overhung section can be formed without a support.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an object producing technique for producing an object having a desired shape by an additive manufacturing method.

[0002]

2. Description of the Related Art In recent years, various additive manufacturing methods have been developed as a technique for forming a three-dimensional three-dimensional object by computer control. These additive manufacturing methods have the following advantages as compared with conventional shaping by removal processing such as cutting (including molding of a mold for casting, plastic working, and injection molding). That is, even a three-dimensional object having a complicated internal structure in which a cutting blade cannot enter can be automatically created by one molding process.

[0003] Since non-contact machining is performed, tool management such as tool change and countermeasures against tool wear is not required, and unattended operation can be performed at night.

[0004] Since no chips are generated and there is no noise or vibration, the device can be operated even in an office work environment.

[0005] Anyone can operate without the need for machining expertise.

[0006] As typical methods of the additive manufacturing method having such characteristics, a stereolithography method, a powder sintering method, an extrusion method,
A sheet cutting method, an ink jet method and the like are known. FIG. 38 shows the principle of these additive manufacturing methods.

In the stereolithography method, as shown in FIG. 37 (a), a liquid photo-curable resin is irradiated with light such as an ultraviolet laser beam, and the light-irradiated portion is cured by a polymerization reaction to form a solidified layer. Forming, solidifying the solidified layer by a very small amount from the liquid level of the photocurable resin liquid, and forming the next solidified layer by light irradiation. It is a method of producing things. As the stereolithography, for example, Japanese Patent Application Laid-Open No. Hei 5-9231 is disclosed.

[0008] The powder sintering method is similar to the stereolithography method. As shown in FIG. 37 (b), powder is used as a material, and the powder is heated by beam heating (CO ₂ laser beam or the like). In this method, the particles are bonded to each other, and the sintered powder layers are sequentially laminated.

In the extrusion method, as shown in FIG. 37 (c), a thermoplastic or photo-curable wax or resin is extruded from a thin nozzle, and the thin linear resin is scanned in a plane while being cured. This is a method of performing additive manufacturing. The extrusion method is described in, for example, Japanese Patent Application Laid-Open No. 2-13013.
No. 2, JP-A-8-156106 and the like are disclosed.

In the sheet cutting method, as shown in FIG. 37 (d), a sheet material such as paper or resin is cut, and the cut sheet materials are laminated by heat compression or the like.

The ink jet method employs an ink jet head established in the field of printer technology, as shown in FIG.
As shown in, the droplets such as wax melted by heating are continuously dropped and solidified, or a photo-curable resin or the like is jetted, and the jetted photo-curable resin or the like is irradiated with light. It is a method of solidifying. As the ink jet method, for example, JP-A-2-307728 and JP-B-7-55538 are disclosed.

[0012]

However, the conventional additive manufacturing method has the following problems.

[0013] That is, the molding accuracy of the conventional molding process such as the cutting process is on the order of 0.01 mm, while the molding accuracy of the optical molding method is on the order of 0.1 mm, which is inferior. In addition, in the stereolithography method, a tank for storing the photocurable resin liquid is required, and the apparatus is increased in size, and the photocurable resin liquid that is not used for modeling in the tank is irradiated with light during molding. As a result, the performance is deteriorated due to the influence, and it has to be discarded, resulting in waste of resources.
Further, in the optical molding method, a support for molding the overhang portion is required, and the molding time has been long. In addition, there were few kinds of usable materials.

In the powder sintering method, since a CO ₂ laser beam having a long wavelength is used, there is a limit in reducing the minimum unit of the molding by narrowing the beam diameter, and the molding accuracy is further inferior to the optical molding method. . Further, a high output CO ₂ laser beam is required, and ancillary equipment for increasing the ambient temperature is required. Furthermore, the powder sintering method does not require support for forming the overhang portion, but it removes the molded object buried in the unsintered powder after molding, or removes the unsintered material remaining inside the molded object. A step of removing the powder was required, and the molding time was long.
Further, the types of usable materials were limited to powders, and were few.

In the extrusion method, the extruded resin expands due to the "extrusion expansion" phenomenon, so that the minimum unit of molding is larger than the diameter of the resin supply nozzle, and the diameter of the resin supply nozzle is 0.1 mm or less at present. However, there is a problem that the molding accuracy is reduced. Also,
Support for modeling the overhang was required, and the modeling time was long.

In the sheet cutting method, there is a problem that the shaping accuracy is lowered because the shaping unit is limited by the thickness of the laminated sheets. In addition, although support for forming the overhang is not required, it is necessary to manually remove the sheet portion other than the formed object manually after forming, which increases the forming time and may result in damage to the formed object. There was also.

On the other hand, the ink jet method has been established in the field of printers, and the resolution of the ink jet head has been increased to about 720 dpi. Is possible. It is also possible to use a relatively large number of types of materials and eliminate waste of materials. Also,
Since no tank is required in the stereolithography method, the size can be reduced.

However, in the conventional ink-jet method, the degree of freedom in molding is low, and the irradiation direction of the material and the phase transformation promoting factor is limited to one direction. Apart from that, support was needed and the modeling time was long.

In the conventional additive manufacturing method, three-dimensional CA
STL (Stereolitho) for modeling from D data
(Graphile File) data, and the accuracy of this data conversion is low at present, so that the data must be manually corrected, and the time required for modeling is long. In addition, there is a demand for improving a molding function such that an object having a desired specification can be obtained quickly by reliably generating an object having a desired specification and eliminating the need for modified molding. Was.

Further, in the conventional laminating method, even if a single material supply head is provided and a plurality of supply ports (nozzles) are provided in the material supply head, the arrangement of the nozzles is limited. Therefore, the molding speed and the molding accuracy were insufficient.

The present invention has been made under such a background, and an object of the present invention is to improve a function of generating an object by an additive manufacturing (generation) method.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an object producing apparatus according to the present invention. The object producing apparatus is an object producing apparatus based on an additive manufacturing (generating) method, and an object 1 is provided.

And a promoting action start time determining unit 7.

Further, the present object producing apparatus includes a material supply unit 1

A driving unit 10 such as a motor as a driving source for moving the position of the mounting stage 9; a driving control unit 11 for controlling the driving of the driving unit 10 to move the mounting stage 9; Supply unit 1 and promotion factor supply unit 4,
And a position detector 1 for detecting the current position of the mounting stage 9

The supply control unit 2, the material supply timing determination unit 3, the promotion control unit 6, the promotion operation start time determination unit 7,
Some or all of the functions of the scanning control unit 8 and the drive control unit 11 are actually realized by the computer 14 (see FIG. 2). However, the material supply timing determination unit 3 and the promotion operation start time determination unit 7 determine the material supply timing and the promotion operation start based on an electrical switch that is turned on / off in synchronization with the position signal detected by the position detection unit 12. It may be configured by an electrical device configured to determine the timing.

The computer 14 has a CPU 14a, an RO
M14b and RAM 14c, and the CPU 14a
While using M14c as a work area, ROM
8b based on the program stored in FIG.
0, various processes as shown in FIGS.

FIG. 2 is an external view showing a schematic configuration of the object producing apparatus according to the present invention. The material supply unit 1 and the acceleration factor supply unit 4 are attached to the scanning stage 15, and the scanning control unit 8 controls the driving of the X drive mechanism 16 and the Y drive mechanism 17 (corresponding to the drive unit 10 in FIG. 1). It moves in the X and Y directions together with the scanning stage 15. The mounting stage 9 moves in the vertical (Z) direction by controlling the driving of a Z driving mechanism 18 (corresponding to the driving unit 10 in FIG. 1) by the driving control unit 11.

The X drive mechanism 16, the Y drive mechanism 17,
The Z drive mechanism 18 can be constituted by, for example, a drive mechanism in which a ball screw that is rotationally driven by a stepping motor and a nut that is screwed to the ball screw in a rotation inhibited state are combined. In the case of such a configuration, the position detection unit 12 may be configured to perform the position detection based on, for example, the rotation angle of the stepping motor (that is, the number of drive pulses).

The material supply unit 1 and the acceleration factor supply unit 4 are attached to the scanning stage 15 in a state as shown in FIG. 3, for example. That is, the material supply unit 1 is fixed to the scanning stage 15 in such a manner as to discharge (eject) the material M in the Z direction. On the other hand, the facilitating factor supply unit 4 is inclined at a predetermined angle with respect to the material supplying unit 1 so that the facilitating factor F is irradiated to a position where the material M discharged from the material supplying unit 1 reaches the generation surface. And is fixed to the scanning stage 15. In other words, the material supply unit 1 and the acceleration factor supply unit 4
Is mounted on the scanning stage 15 so that the direction of travel of the material M and the advancing factor F make a predetermined angle in the same vertical plane.

By moving the scanning stage 15 in the direction of arrow A shown in FIG. 3, the supply scan of the material M and the facilitating factor F is performed. Thus, when the supply scan of the material M and the promotion factor F is performed, the material supply unit 1 and the promotion factor supply unit 4
Need not be individually moved, and only the scanning stage 15 needs to be moved, so that the apparatus configuration and the control system can be simplified.

As the material supply unit 1, for example, a thermal ink jet head 101 whose technology has already been established in the field of printers as shown in FIG. 4 can be used. This thermal inkjet head 101
Material supply pipe 101 for supplying material M such as a photocurable resin liquid
a, a plurality of material chambers (not shown) for storing the material M supplied from the material supply pipe 101a, heating elements (not shown) for heating the material M stored in each material chamber, and provided in each material chamber. It has a plurality of nozzles 101b.

A plurality of material supply pipes are provided corresponding to the plurality of material chambers and the nozzles 101b, and different materials M are supplied from the plurality of material supply pipes and the corresponding nozzles 1 are provided.
Different materials M may be ejected from 01b.

The ejection principle of the thermal ink jet head 101 is as follows. The material M in the material chamber is heated by a heating element to increase the pressure in the material chamber, and the high pressure causes the nozzle 101 b
The material M is ejected from the apparatus. It is also possible to use a piezo-type inkjet head that discharges the material M by increasing the pressure in the material chamber by denting the wall of the material chamber by controlling the voltage applied to the piezo element.

The resolution of these ink-jet heads, that is, the minimum generation unit for generating the target object 13 is currently 1440 dpi or more, and it is technically possible to further reduce the resolution. Is supplied, it is possible to realize a high production accuracy on the order of 0.1 mm or more.

As shown in FIG. 5, a dispenser type discharge head 102 utilizing air pressure or the like can be used as the material supply section 1. When the dispenser type ejection head 102 is used, a heat-meltable resin, a thermoplastic resin, or the like is used as the material M, and the accelerating factor supply unit 4 ejects a low-temperature medium as the accelerating factor F corresponding to the material M. The cooling nozzle 103 to be used will be used.

Note that 102a shown in FIG. 5 is a material supply pipe, and 102b is a nozzle.

The directing section 5 can be constituted by, for example, a parabolic mirror 19 as shown in FIG. Inside the parabolic mirror 19, an ultraviolet irradiating unit 20 as the facilitating factor supply unit 4 is arranged, and the ultraviolet light radiated from the ultraviolet irradiating unit 20 is reflected by the parabolic mirror 19 and collected at one point. It is illuminated.

The parabolic mirror 19 and the ultraviolet irradiation unit 20
Is rotatably supported by a rotation mechanism 21, and the rotation mechanism 21 (that is, the parabolic mirror 19 and the ultraviolet irradiation unit 20)
Is attached to the first stage 22 which is configured to be movable. That is, the first stage 22 includes a motor,
And a gear attached to the rotating shaft of the motor. Further, teeth are formed on both sides of the guide plate 23, and the teeth on one side are meshed with the teeth, and the first stage 22 is configured to move in the Y direction by rotating the motor. .

The guide plate 23 is also moved in the X direction by the X drive mechanism 16 as shown in FIG.
It is movable in the Y direction.

The material supply unit 1 is rotatably supported by a rotation mechanism 24. The rotation mechanism 24 (that is, the material supply unit 1) is attached to a second stage 25 that is configured to be movable. I have. That is, similarly to the first stage 22, the second stage 25 has a motor and a gear mounted on the rotating shaft of the motor, and the gear is meshed with the teeth on the other surface of the guide plate 23. When the motor rotates, the second stage 25
It is configured to move in a direction. In other words, the material supply unit 1 is also movable in the X and Y directions, similarly to the promotion factor supply unit 4.

In such a configuration, the angle of incidence of the material M on the generation surface can be arbitrarily changed by changing the attitude of the material supply unit 1 by the rotation mechanism 24. By changing the attitude of the facilitator supply unit 4 (that is, the parabolic mirror 19), it is possible to irradiate the ultraviolet rays so as to follow the incident point of the material M, so that an overhang portion is generated without using a support. It becomes possible. In addition, since the material M can be irradiated with the ultraviolet light in a pinpoint manner by condensing the ultraviolet light on the incident point of the material M by the parabolic mirror 19, the phase transformation of the material M is efficiently promoted. It becomes possible.

When the material supply unit 1 and the acceleration factor supply unit 4 are supported by the rotating mechanisms 24 and 21 as described above,
When the supply scan of the material M and the promotion factor F is performed, the X and Y positions of the material supply unit 1 and the promotion factor supply unit 4, that is, the X and Y positions of the second stage 25 and the first stage 22, are fixed.
The supply scan of the material M and the acceleration factor F is performed only by the rotation drive of the rotation mechanisms 24 and 21 or the rotation mechanisms 24 and 21
By keeping the material supply unit 1 and the acceleration factor supply unit 4 in a fixed posture, the Y of the second stage 25 and the first stage 22 are maintained.
The supply scan of the material M and the acceleration factor F may be performed by moving only the position. However, in each case,
When the overhang portion is generated, the X, Y positions and postures of the material supply unit 1 and the acceleration factor supply unit 4 are changed more greatly than when other portions are generated.

As shown in FIG. 7, the directing section 5 can be constituted by a galvanomirror. The galvanomirror is composed of a rotatable X-axis mirror 26 and a Y-axis mirror 27. For example, the galvano mirror converts an acceleration factor F (laser beam) output from a laser light source 28 as an acceleration factor supply unit 4 into an X-axis mirror. 26, the laser beam can be scanned by being deflected by the Y-axis mirror 27.

As described above, since scanning can be performed by the X-axis mirror 26 and the Y-axis mirror 27, the facilitating factor supply unit 4 (laser light source 23) itself may be fixedly arranged. Note that, also in the example of FIG. 7, the material supply unit 1 is rotatably supported by the rotation mechanism 24, so that the same effects as in the example of FIG. 6 can be obtained.

Next, the object generation operation will be described with reference to the flowchart of FIG.

First, the three-dimensional CAD data is described in the scanning direction of the material M and the acceleration factor F, that is, in the example of FIG.
The coordinate system is converted to a coordinate system in which the direction in which the arrival point of the material M / promoting factor F moves in the generation plane as one coordinate axis as shown by an arrow A (step S1). Next, the coordinate-converted three-dimensional shape data is re-described as a plurality of cross-sectional data in a bitmap format sliced in the Z direction orthogonal to the generation plane of the object (step S2). It is preferable that the slice thickness is changed according to the gradient of the surface of the modeled object in order to reduce the step on the surface of the modeled object.

Next, the basic specifications of the generation operation are determined so as to satisfy the specifications such as the generation accuracy and the function of the object (step S3). The basic specifications of the generation operation include, for example, the discharge amount of the material M by the material supply unit 1, the intensity (such as laser power) of the promotion factor F by the promotion factor supply unit 4, the material supply unit 1, and the promotion factor supply unit 4. , Mounting stage 9
And the moving speed at the time of moving.

Then, in consideration of the basic specifications of the generating operation, a moving path such as a moving distance and a reversing position of the material supplying unit 1, the promoting factor supplying unit 4, and the mounting stage 9 is determined (step S).
4). Next, a drive control procedure such as acceleration / deceleration timing, acceleration, and the like for each scanning path of the material supply unit 1 is determined (Step S).
5) A material supply control procedure such as a discharge frequency and a discharge timing of the material M is determined (step S6), and a promotion action control procedure is determined according to the discharge of the material M (step S6).
7).

Next, based on the basic specification of the generating operation determined in step S3 and the movement path determined in step S4, the material supply unit 1, the promotion factor supply unit 4, and the mounting stage 9 are moved ( Step S8). And step S
The material supply unit 1 supplies the material M based on the generation operation basic specifications determined in Step 3, the drive control procedure determined in Step S5, and the material supply control procedure determined in Step S6 (Step S6). S9). Next, step S
The promotion factor supply unit 4 supplies the promotion factor F based on the generation operation basic specifications determined in Step 3 and the promotion action control procedure determined in Step S7 (Step S10).
Note that the processes of steps S8 to S10 are performed in parallel.

Then, it is determined whether or not the object generation has been completed, that is, whether or not all the layers have been generated (step S11). If all the layers have been generated, the process is terminated.
On the other hand, if all the layers have not been generated, the process returns to step S3 to perform a similar target object generation process based on the cross-sectional data of the next layer.

As described above, the description of the three-dimensional CAD data is converted into coordinate data using the scanning direction of the material and the acceleration factor as one coordinate axis, and a bitmap format is formed based on the coordinate-converted three-dimensional shape data. Section data is being created. Therefore, phase information is not required by the above coordinate conversion, and only graphic information, that is, cross-sectional data in a bitmap format is sufficient, and a target object can be generated by repeating a process equivalent to a printing technique. STL (Stereolith)
The step of converting the data into an OG (Ography File) data is unnecessary.

Next, another example of the generating operation will be described with reference to the flowchart of FIG. This generation operation is obtained by adding steps S101 to S103 to the generation operation of FIG.

That is, after the generation operation basic specifications are determined in step S3, the generation operation basic specifications are determined based on the cross-sectional data corresponding to the generation surface (layer) to be generated and the generation operation basic specifications determined in step S3. The generation state of the object on the generation surface is simulated (step S101). Then, it is determined whether or not the state of generation of the target by the simulation satisfies the specification of the target (step S102). As a result, if the specification of the object is satisfied, the process proceeds to step S4.

On the other hand, if the specifications of the object are not satisfied, the basic specifications of the generating operation determined in step S3 (particularly, the material discharge amount and the intensity of the acceleration factor) are changed (step S103), and the process returns to step S101. Then, the generation state of the object on the generation plane is simulated based on the basic specification of the generation operation according to the change. In this case, until the simulation results meet the target specification
The change of the generation operation basic specification is repeatedly performed.

As described above, the generation operation basic specifications of each layer are determined, and a simulation is performed before executing the actual generation processing based on the generation operation basic specifications, and it is confirmed that the generation operation basic specifications are appropriate. Since the actual generation processing is executed later, it is possible to prevent the generation of the target object that does not satisfy the specifications.

Next, another example of the generating operation will be described with reference to the flowchart of FIG. In this generation operation example, when it is determined No in step S11, the generation in all the layers is performed without returning to step S3 as shown in FIGS. The state is simulated collectively. Therefore, in the present generation operation example, each determination process in steps S4 to S7 is performed for all layers, and each generation operation in steps S8 to S10 is performed for one layer.

It is also possible to simulate the generation state of the next layer while performing the operation of generating a certain layer.

FIG. 11 is a block diagram showing another schematic configuration of the object generating apparatus. This object generating apparatus is obtained by adding an observation unit 24 to the object generating apparatus of FIG. is there.

The observation section 24 observes the generated target object or the actual generation operation state (e.g., the discharge state of the material M), and is constituted by an image pickup device such as a CCD. The obtained image data is input to the computer 14. And the computer 14
Evaluates the generation state of each layer based on the input image data, reflects the evaluation result in the generation operation of the next layer, or evaluates the entire target object for which the generation processing of all layers is completed, For example, correction generation processing is performed based on the evaluation result.

It is natural that the observation section 24 is arranged so as to be able to image a target object or the like without interfering with the material supply section 1 and the promotion factor supply section 4. However, the observation section 24 is fixedly arranged at a predetermined position. Alternatively, it may be arranged so that position movement and attitude control can be performed so that imaging can be performed from an arbitrary viewpoint.

Next, an example of the operation of generating the object corresponding to the configuration example of FIG. 11 will be described with reference to the flowcharts of FIGS.

First, the three-dimensional CAD data is described in the scanning direction of the material M and the acceleration factor F, that is, in the example of FIG.
The coordinate system is converted into a coordinate system in which the direction in which the arrival point of the material M / promoting factor F moves in the generation plane as one arrow A as one coordinate axis (step S21). Next, the coordinate-transformed three-dimensional shape data is re-described as a plurality of cross-sectional data in the bitmap format sliced in the Z direction orthogonal to the generation plane of the object (step S22). It is preferable that the slice thickness is changed according to the gradient of the surface of the modeled object in order to reduce the step on the surface of the modeled object.

Next, the basic specifications of the generation operation are determined so as to satisfy the specifications such as the generation accuracy and the function of the object (step S23). As a basic specification of this generation operation,
For example, the discharge amount of the material M by the material supply unit 1 and the intensity (such as laser power) of the promotion factor F by the promotion factor supply unit 4
In addition, the initial position of the material supply unit 1, the acceleration factor supply unit 4, and the mounting stage 9 and the moving speed at the time of moving the stage.

After the generation operation basic specifications are determined in step S23, the generation plane (layer) to be generated from now on
Is simulated based on the cross-sectional data corresponding to and the generation operation basic specification determined in step S23 (step S2).
4). Then, it is determined whether or not the state of generation of the target by the simulation satisfies the specification of the target (step S25). As a result, if the specification of the object is satisfied, the process proceeds to step S27.

On the other hand, if the specification of the object is not satisfied, the basic specification of the generating operation (particularly, the material discharge amount and the intensity of the acceleration factor) determined in step S23 is changed (step S26), and the process returns to step S24. Then, the generation state of the object on the generation plane is simulated based on the basic specification of the generation operation according to the change. In this case, the generation operation basic specifications are repeatedly changed until the result of the simulation satisfies the target specification.

As described above, the generation operation basic specifications of each layer are determined, and a simulation is performed before executing the actual generation processing based on the generation operation basic specifications, and it is confirmed that the generation operation basic specifications are appropriate. Since the actual generation processing is executed later, it is possible to prevent the generation of the target object that does not satisfy the specifications.

In step S27, a moving path such as a moving distance and a reversing position of the material supply unit 1, the promotion factor supply unit 4, and the mounting stage 9 is determined based on the above-described basic specification of the generating operation. Then, a drive control procedure such as acceleration / deceleration timing and acceleration for each scanning pass of the material supply unit 1 is determined (step S28), and a material supply control procedure such as a material discharge frequency and a discharge timing is determined (step S29). , A procedure for controlling the accelerating action in accordance with the discharge of the material is determined (step S3).
0).

Next, the material supply unit 1, the promotion factor supply unit 4, and the mounting stage 9 are moved based on the movement path determined in step S27 (step S31). And
The material supply by the material supply unit 1 is performed based on the basic specification of the generating operation determined in step S23, the drive control procedure determined in step S28, and the material supply control procedure determined in step S29 ( Step S3
2). Next, the promotion factor is supplied by the promotion factor supply unit 4 based on the generation operation basic specifications determined in step S23 and the promotion action control procedure determined in step S30 (step S33).

Then, it is determined whether or not the object generation is completed (step S34). If not completed, the process returns to step S23 to perform the object generation processing based on the next section data. On the other hand, when the object generation is completed, the product is evaluated based on the image data from the observation unit 24 (step S35). Then, it is determined whether or not the product (target) satisfies the specification of the target (step S36), and if the specification of the target is satisfied, the process ends.

On the other hand, if the specification of the object is not satisfied, correction data is created (step S37), a generation process for correction is executed based on the correction data (step S38), and the process is terminated.

As described above, the observation / evaluation function is mounted on the object generation apparatus, and the observation / evaluation is performed when the object generation processing is completed. When the specification of the object is not satisfied, the correction generation is immediately performed. Processing is performed. Therefore, for example, the generated target object is transferred from the target object generation device to another observation / evaluation device and observed / evaluated. If the specification is not satisfied, correction data is created by the observation / evaluation device, and the correction is performed. There is no need to perform a troublesome operation such as transferring the data and the object to the object generating apparatus and performing the correction generation process, and the object that satisfies the specifications can be quickly obtained.

Next, another example of the operation of generating the object corresponding to the configuration example of FIG. 11 will be described based on the flowcharts of FIGS. In this operation example, steps S21 to S34 are completely the same as the operation examples in FIGS. 12 and 13, and therefore description thereof will be omitted, and only step S34 and subsequent steps will be described.

In this operation example, if it is determined in step S34 that the processing for generating the target object has been completed, the processing ends. If it is determined that the generation processing has not been completed, the observation unit 2
The product is evaluated based on the image data from Step 4 (Step S201). Then, it is determined whether the product (target) satisfies the specification of the target (step S20).
2) If the specification of the object is satisfied, step S23
Then, a process of generating an object based on the next section data is performed.

On the other hand, if the specification of the object is not satisfied, correction data is created (step S37), and the process returns to step S23 to perform a process of generating the object based on the next section data. When the correction data is created in this way, in step S23, the generation operation basic specifications in the next generation step are determined based on the next cross-section data and the correction data. That is, the correction data is reflected in the basic specification of the generation operation in the next generation step based on the next cross-sectional data, so that the defect generation part in the previous generation step was substantially corrected in the next generation step. In this state, the next layer is generated.

As described above, each time one layer is generated based on one section data, observation and evaluation are performed. If the specification is not satisfied, correction data is created, and in the process of generating the next layer. By performing the correction generation at the same time, it is possible to reliably obtain a product that satisfies the specifications when the generation processing is completed.

As described above, in the process of generating the next layer, without performing the correction generation at the same time, after performing the correction generation processing for the purpose of correction only, the generation processing of the next layer is performed. Is also good. In addition, the generation state is observed and evaluated in real time during the generation process of each layer, and the evaluation result is reflected in the generation process of the layer currently being generated. May be further ensured to obtain a product that satisfies the specifications at the time when is completed. Further, in the operation examples of FIGS. 12 and 13 and FIGS. 14 and 15, by simulating the next layer in parallel with the generation processing of each layer, it is also possible to quickly generate an object satisfying specifications. is there.

Next, an example of the structure of the material discharge port (working portion: the nozzles 1011b and 102b) of the material supply section 1 will be described with reference to FIGS. 16 to FIG.
In FIG. 9, the material discharge port of the material supply unit 1 is shown. However, the promotion factor supply port (working unit) of the promotion factor supply unit 4 such as the cooling nozzle 103 can be similarly configured. 16 to 29, the material discharge ports are shown as circular or elliptical.

In the example of FIG. 16, a plurality of material discharge ports are provided on one material supply section (material supply head), and the plurality of material discharge ports are linearly arranged in one or two rows. Have been.

As described above, by providing a plurality of material discharge ports, the number of material discharges per unit time or the amount of material discharge per unit time can be increased as compared with the case of a single material discharge port, and the molding speed can be reduced. It can be faster.

In the case of a single material discharge port, it is necessary to make the scanning pitch of the material supply unit 1 fine in order to increase the molding accuracy, and the number of scans and the molding time are long.
When a plurality of material discharge ports are provided, only by narrowing the arrangement interval of these material discharge ports, it is possible to increase the molding accuracy without making the scanning pitch fine, improving both the molding speed and the molding accuracy. It is possible to do.

Further, by arranging a plurality of material discharge ports on a straight line, when discharging the material in synchronization with the movement of the material supply unit 1 or the like, the control of the discharge timing becomes easy, and the molding speed is increased. And the variation in the arrival position of the ejected material is eliminated, and the modeling accuracy can be improved.

By arranging a plurality of material discharge ports not only in the column (column) direction but also in the row direction, it is possible to improve the molding speed. Modeling and patterning can be performed, and the modeling accuracy can be improved.

In the example of FIG. 17, the arrow indicates the relative movement direction of the material supply unit 1 and the mounting stage 9 on which the object 13 is mounted. In other words, this indicates that the arrangement direction of the material discharge ports of the material supply unit 1 is parallel to the relative movement direction.

As described above, when the material discharge ports are arranged in parallel to the relative movement direction, by controlling the material discharge timing by the relative movement speed, it is possible to form a finer and more accurate molding, and at the same time, to perform high-speed molding. It is also possible to make various shapes. In other words, by slightly shifting the ejection timing of each material ejection port, an effect equivalent to increasing the ejection frequency can be obtained, and the speed of relative movement required for molding can be increased, thereby improving the molding speed. It becomes possible.

In the example of FIG. 18, the arrow indicates the relative movement direction of the material supply unit 1 and the mounting stage 9 on which the object 13 is mounted. In other words, this indicates that the arrangement direction of the material discharge ports of the material supply unit 1 is perpendicular to the relative movement direction.

As described above, when the arrangement direction of the material discharge ports is perpendicular to the direction of relative movement, modeling or patterning can be performed on a wider area at one time, and the modeling speed in one relative movement is high. Become. In addition, by arranging the material ejection ports so as to correspond to a desired modeling pattern, it becomes possible to perform more accurate patterning at a higher speed.

In the example of FIG. 19, a plurality of material discharge ports arranged in a straight line at equal intervals are arranged in two rows. In this regard, the arrangement is the same as in FIGS. 16 (b), 17 (b) and 18 (b), but in FIG. 19, the arrangement of the first row shown in R1 and the arrangement of the second row shown in R2 Is shifted by a half pitch of the arrangement interval (array pitch) of each row.

In the example of FIG. 20, similarly to FIG. 19, the arrangement of the first row shown in R1 and the second row shown in R2 are out of phase. The value is not a half pitch of the arrangement interval (array pitch) but a value larger than the half pitch.

In the example of FIG. 21, a plurality of material discharge ports arranged in a straight line at equal intervals are arranged in three rows. The arrangement of each row shown in R1, R2, and R3 is out of phase with each other, and furthermore, the amount of phase shift between the arrangement of the first row (R1) and the arrangement of the second row (R2), Line 2 (R
The phase shift amount between the array of 2) and the array of the third row (R3) is different. The line spacing between the first line (R1) and the second line (R2), the second line (R2) and the third line (R3)
Is different from the line spacing of
It is narrower than the arrangement interval.

As described above, when the material discharge ports are arranged at regular intervals, the patterning of an arbitrary pattern or the formation of an arbitrary shape can be performed while maintaining the molding speed and the molding accuracy by controlling the material discharge timing. Can be performed.

In the example of FIG. 22, a plurality of material discharge ports are arranged with a regularity of repeating the arrangement pattern of C1, C2, and C3.
1, R2, the first and second rows have the same phase.

In the example of FIG. 23, the arrangement of each row has the same regularity as in FIG. 22, but the phases are shifted between the first row and the second row.

In the example of FIG. 24, there are two types of regular arrays, such as the first row (R1) array and the second row (R2) array, and these two types of regular arrays. Are arranged at regular intervals in the row direction, and there is no phase shift between the combinations of the two types of arrangements.

In the example of FIG. 25, as in FIG. 24, there are two types of regular arrays, and these two types of regular arrays are repeatedly arranged in the row direction at equal intervals. The phase is shifted between the combination of these two types of regular arrangements.

The regularity of the arrangement of the material discharge ports is as follows.
By setting the regularity corresponding to the desired shaping pattern, the desired shaping pattern can be formed efficiently and with high precision. Further, by shifting the phase between the rows, the pitch of the arrangement of the ejection ports is apparently narrowed, and the modeling accuracy can be improved.

In the example of FIG. 26A, the arrow indicates the relative movement direction of the material supply unit 1 and the mounting stage 9 on which the object 13 is mounted. That is, this indicates that the arrangement direction of the material discharge ports of the material supply unit 1 is inclined by an arbitrary angle with respect to the relative movement direction.

As described above, by giving an arbitrary angle between the arrangement direction of the material discharge ports and the relative movement direction, the arrangement pitch of the discharge ports can be apparently narrowed. It is possible to improve the modeling accuracy without reducing.

The relative movement between the material supply unit 1 and the mounting stage 9 on which the object 13 is mounted is shown in FIG.
Is not limited to linear motion as in FIG.
The same effect can be obtained even with a circular motion as shown in FIG.

In the example of FIG. 27A, the length of one row of the material discharge ports is determined by the cross-section X of any one of the object formation spaces.
It is longer than the length that traverses. FIG.
In the example of (b), an array having a length as shown in FIG.
It is arranged over two rows.

As described above, by setting the arrangement length of the material discharge ports in the row direction to be longer than the length traversing any one cross section X of the object formation space, the direction perpendicular to the row direction (column) (Direction, row direction), it is possible to generate the cross section X at one time, and it is possible to further improve the molding speed. In addition, by controlling the discharge timing together with the relative movement, higher modeling accuracy can be achieved without increasing the number of relative movements. The examples of FIGS. 27A and 27B are suitable for the field of printing and for the field of manufacturing semiconductors, liquid crystal substrates, various panels, electric boards, and the like.

In the example of FIG. 28, the arrangement region of the material discharge ports is wider than any one of the cross sections Y of the target object generation space.

For this reason, the cross section Y can be generated at once without giving a relative movement between the material supply unit 1 and the mounting stage 9 on which the object 13 is mounted, and the molding speed can be reduced. Dramatic improvement can be achieved. In addition, the number of times of the relative movement in the case of increasing the modeling accuracy can be reduced, and the modeling accuracy can be easily improved by simple control.

In the example shown in FIG. 29A, the material discharge ports are arranged for one row, the arrangement interval in the row direction is irregular, and they are not arranged on a straight line, and the columns (digits) are not arranged. The position in the direction is also irregular. In the example of FIG. 29B, the material discharge ports are arranged irregularly over the entire area of the discharge port arrangement surface.

The irregular arrangement of the material discharge ports in this way is significant in the following points. That is, depending on the regular arrangement of the material discharge ports and the regular relative movement required for modeling and patterning, a certain kind of geometric pattern may be formed (for example, a polishing pad pattern may be formed on a wafer). In the case where the material discharge ports are irregularly arranged as described above, when molding or patterning is required over the front surface such as coloring, painting, etc., the front surface is not moved without performing relative movement. It is possible to form or pattern uniformly.

Next, a material supply unit 1, an acceleration factor supply unit 4,
Various configuration examples of the observation unit 24 and the like will be described with reference to FIGS.

In the example of FIG. 30, the dispenser type material supply unit 1a and the ink jet type material supply unit 1b are
It has two material supply units. In addition, two acceleration factor supply units 4a and 4b are provided corresponding to these two material supply units.

Thus, by providing two material supply units, for example, the main part of the object 13 is formed by the dispenser type material supply unit 1a, and the overhang portion is formed by the ink jet type material supply unit 1b. can do. For this reason, it is possible to execute the molding process at once without dividing the molding process into multiple stages, and it is possible to improve the molding speed.

Further, since the minimum unit of the size of the discharge material is different due to the difference in the material supply method, for example, a rough shape is formed by a dispenser type material supply unit 1a, and a finer shape is formed by an ink jet type material supply unit 1b. It is possible to selectively use such as finishing a part, and it is possible to improve the molding accuracy without reducing the molding speed.

In the example of FIG. 31, one material supply unit 1c
And two promotion factor supply units 4c and 4d. And, for example, the material supply unit 1c is provided with a heat-fusible material Ma.
The facilitating factor supply unit 4c discharges the high-temperature medium Fa near the reaching point of the material Ma in order to enhance the adhesion between the object 13 already formed and the material Ma discharged this time,
Point heat melting is performed near the arrival point. Next, the facilitator supply unit 4d
Discharges the low-temperature medium Fb in the vicinity of the above-mentioned reaching point to cool and solidify.

By increasing the adhesiveness in this manner, the molding density at the molding point is increased, and the mechanical properties of the object 13 and the molding accuracy can be improved. In addition, since a cooling promoting factor is also supplied, the phase transformation of the material can be completed quickly, and the molding speed can be improved.

In the example of FIG. 32, there are two material supply units and one accelerator supply unit, and the two material supply units are configured to supply different materials from each other.

That is, the material supply section 1 d
骨 格 to supply the secondary material Mb,
The material supply unit 1e supplies a binder Mc for bonding and curing the secondary material Mb. Further, the facilitator supply unit 4e
Supplies a guide beam Fc for promoting the arrangement and alignment of the framework material Md.

Here, a microsphere is assumed as the skeleton material Md. And the microsphere-shaped skeletal material M
d is aligned by the guide beam Fc, a secondary material Mb is supplied to the aligned skeletal material Md, and is solidified by the binder Mc.

With such a configuration, for example, when an object composed of various skeleton materials having different mechanical properties and secondary materials of various colors is to be produced, a conventional method is used. In addition, there is no need to mold and assemble each part or to color after assembling. In other words, even if the object is composed of different materials, the desired object can be formed collectively by a series of forming processes without repeating the forming process for each material, and the forming speed is improved. It becomes possible.

Further, since there is no time lag between modeling processes, generation of a modeling error or the like with the passage of time is suppressed, and high modeling accuracy can be realized.

In the example shown in FIG. 33, the facilitating factor supply units 4f and 4g and the observation units 24a and 24b are connected to the material supply unit 1f.
Are configured to move together. In other words, the movement of the material supply unit 1f and the promotion factor supply unit 4
f, 4g and the movement of the observation units 24a, 24b.

The combination of the two components that move together is arbitrary. For example, the material supply unit and the facilitator supply unit can be moved integrally with respect to the observation unit. The two observation units 24a and 24b perform observation and evaluation using different techniques.

As described above, by moving the other two components integrally with respect to one of the three components, the material supply unit, the acceleration factor supply unit, and the observation unit, The two components can take an optimal action state integrally with the action of one component, and the modeling process can be optimized, and the modeling accuracy can be improved.

In addition, the restrictions on the arrangement of each component are reduced, and by operating each component in parallel,
It is possible to improve the molding speed.

Further, by providing a plurality of observation units using different techniques, accurate observation / evaluation information can be fed back to the molding process control, and the molding accuracy can be improved.

The example of FIG. 34 has a material supply section 1g, acceleration factor supply sections 4h and 4i, and observation sections 24c and 24d. These three types of components may be configured to move integrally, or may be configured to move independently of each other.

As described above, by making all the three components of the material supply unit, the accelerating factor supply unit, and the observation unit integrally movable, alignment between the components can be performed with high accuracy. It is possible to improve the modeling accuracy. Further, three components can be driven by one drive mechanism, and the apparatus configuration is simplified and control is facilitated, so that the molding speed can be improved. In particular,
In planar modeling performed in the printing field, semiconductor manufacturing process, and the like, since movement in the thickness direction is small, it is possible to further improve modeling accuracy.

Also, by moving the three components together, the three components can be integrated into an optimal working state, and the molding process can be optimized and the molding accuracy can be improved. It becomes possible.

On the other hand, when the three components, that is, the material supply unit, the promotion factor supply unit, and the observation unit, can be moved independently of each other, these components may take an optimal operating state for each modeling point. Thus, the modeling process is optimized, and the modeling accuracy can be improved.

In addition, the restrictions on the arrangement of the components are further reduced, and the molding speed can be improved by operating the components in parallel.

The example of FIG. 35 has a material supply section 1h, acceleration factor supply sections 4j and 4k, and observation sections 24e and 24f. The two observation units 24e and 24f are configured to be controlled to move in an arc-shaped movement trajectory by independent drive mechanisms (not shown).

By using such a mechanism for moving the observation unit, the observation unit can be moved to a position where the molding situation at each molding point can be grasped more accurately, so that accurate observation / evaluation information can be used in the molding process. It is possible to feed back and improve the modeling accuracy.

Further, since observation / evaluation can be performed from various directions, it is possible to optimize the setting of the next process using the observation / evaluation information. Therefore, a desired object can be obtained, and the molding speed can be improved.

In the example of FIG. 36, the parallel link mechanism 1 is used as a driving mechanism for the material supply unit, the acceleration factor supply unit, and the observation unit.
13, 114 are used.

The parallel link mechanisms 113 and 114
Has a base portion 17 and an end effector portion 18, and a material supply portion, an acceleration factor supply portion, or an observation portion is attached to the end effector portion 18. Also, the base 17
And the end effector unit 18 are connected via a plurality of movable units 19 arranged in parallel, and each movable unit 19
It is configured to be expanded and contracted by the actuator 110.

That is, the parallel link mechanisms 113, 1
14 is the end effector unit 1 due to expansion and contraction of the movable unit 19.
8 (that is, material supply unit, promotion factor supply unit, observation unit)
Can be moved in the XYZ three-axis directions orthogonal to each other, or can be rotated by 90 degrees around the three axes, and the material and the accelerating factor can be discharged and observed from multiple directions.

[0147]

As described above, according to the present invention,
By supplying the material by the ink jet head, the minimum generation unit can be reduced, the modeling (generation) accuracy can be improved, and the micro machine can be modeled. Further, since the minimum generation unit is small, the phase transformation can be performed quickly, and a post-curing step is not required since no defective phase transformation occurs, so that the generation time can be shortened.

Further, since the material and the accelerating factor can be irradiated to the generation surface from any direction, the overhang portion can be generated without using a support.

Further, the description of the three-dimensional CAD data is converted into coordinate data in which the scanning direction of the material and the accelerating factor is set as one coordinate data, and a cross-section in a bitmap format is formed based on the coordinate-converted three-dimensional shape data. By creating data, an object can be generated by repeating a process equivalent to a printing technique, so that there is no need to convert CAD data to STL data as in stereolithography, and the generation process can be simplified. It becomes possible.

Since the simulation is performed before executing the actual generation processing based on the determined generation operation basic specification, and after confirming that the generation operation basic specification is appropriate, the actual generation processing is executed. Therefore, it is possible to prevent an object that does not satisfy the specifications from being generated.

Further, the object is observed / evaluated when the generation processing is completed, and when the specification of the object is not satisfied, the correction generation processing is immediately performed. It is possible to obtain it quickly. Also, each time one layer is generated, observation and evaluation are performed. If the specifications are not satisfied, correction data is created, and correction generation is performed simultaneously in the process of generating the next layer. By doing so, it is possible to reliably obtain a product that satisfies the specifications when the generation processing is completed.
