Description

  The present invention relates to a modeling apparatus and a modeling method.

  In recent years, three-dimensional modeling techniques called additive manufacturing (AM), three-dimensional printers, rapid prototyping (RP), and the like have attracted attention (in this specification, these techniques are collectively referred to as AM techniques). The AM technology generates a plurality of slice data by slicing the three-dimensional shape data of a three-dimensional model, and sequentially stacks and fixes a material layer made of a modeling material on a modeling table based on the slice data. This is a technique for producing an object (three-dimensional object).

Patent Document 1 discloses the following three-dimensional modeling apparatus. First, during the modeling process, the blocking door that blocks the work space on the modeling stage from the external space is locked. Then, when unlocking the blocking door after the modeling process based on the ordering data is completed, if the authentication code is associated with the ordering data, the blocking door is only provided when the input verification code matches the authentication code. Release the lock. In this way, it is possible to prevent the modeled object formed on the modeling stage from being taken out by a person other than the modeling requester.
Further, Patent Document 2 discloses a method for manufacturing a three-dimensional structure that includes an enclosure wall installation process, an ink discharge process, and a pressure-curing process, and can make the upper surface of the three-dimensional structure more flat.

In recent years, modeling service providers that receive requests from others through a network or the like and perform modeling output have appeared. Among such requests for modeling output, there are those related to “prototypes” before commercialization, etc., and it may be necessary to manage the appearance and configuration secretly. However, in the conventional technology as described above, while the three-dimensional object that has been shaped and output is delivered to the orderer (client), the appearance and configuration of the three-dimensional object is a person other than the orderer (modeling service provider or delivery person). There is a problem that it can be easily learned.
For this reason, at the time of modeling, a three-dimensional object including a structure corresponding to the three-dimensional model and a cover body that covers the structure may be produced. Thereby, since the produced structure cannot be identified from the appearance, the three-dimensional object can be delivered to the orderer in a secretly managed state.
However, when such a three-dimensional object arrives at the orderer, it may be difficult for the orderer to remove the structure from the cover without damaging the external shape of the structure.

  The present invention has been made in view of the above circumstances, and in a modeling apparatus for manufacturing a three-dimensional object including a structure and a cover body by stacking modeling materials, the structure body is formed from the cover body after the three-dimensional object is manufactured.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be exemplarily described with reference to the drawings. However, unless otherwise specified, various control procedures, control parameters, target values, etc., such as dimensions, materials, shapes, and relative arrangements of the members described in the following embodiments are described in the present invention. It is not intended to limit the scope of the above to only those.
The present invention relates to a layered modeling technique (AM technique), that is, a modeling apparatus that employs a technique for producing a three-dimensional object (three-dimensional object) by arranging modeling materials in two dimensions and laminating them in layers.
In this specification, the three-dimensional model (that is, the three-dimensional object represented by the three-dimensional shape data given to the modeling apparatus) to be produced using the modeling apparatus is referred to as a “modeling object”. In addition, a three-dimensional object produced (output) by the modeling apparatus is referred to as a “modeled object”. In the modeling apparatus, an additional structure (referred to as “additional body”) is modeled simultaneously with a structure corresponding to the modeling target (referred to as “structure”). The additional body includes a “support body” which is a structure for supporting an overhang portion and a weak portion of the structure, and a structure body in order to conceal the appearance (appearance shape) and configuration of the structure. A “cover body” that covers all or part of the structure is included. By removing the additional body (support body and cover body) from the molded object created by the modeling apparatus, a “structure” corresponding to the modeling object is obtained.

As the modeling material, various materials can be selected according to the use, function, purpose, etc. of the modeled object to be produced. In the present specification, a material mainly used for modeling a structure is referred to as “structural material”, and a material mainly used for modeling a support body is referred to as “support material”. When it is not necessary to distinguish between the two, the term “modeling material” is simply used. In addition, although any material may be used for modeling of a cover body, the removal from a structure can be simplified by using a support material.
As the structural material, for example, a thermoplastic resin such as PE (polyethylene), PP (polypropylene), ABS, PS (polystyrene) can be used. Alternatively, a metal material or a ceramic material may be used. As the support material, a material having thermoplasticity and water solubility can be preferably used in order to simplify the removal from the structure. Examples of the support material include carbohydrates, polylactic acid (PLA), PVA (polyvinyl alcohol), and PEG (polyethylene glycol).
Further, in this specification, digital data generated from cross-sectional data obtained by slicing three-dimensional shape data of a stereoscopic model to be produced into a plurality of layers along the stacking direction is referred to as “slice data”. The slice data is generated by adding information such as the cross section data of the support body and the cross section data of the cover body as necessary. A layer formed of a modeling material based on slice data is referred to as a “material layer”. A “material layer” is a layer of particles formed by combining one or more material layers depending on the type of modeling material used.

<Example 1>
Example 1 will be described below.
In this embodiment, a structure and a cover body covering the structure are layered and formed on a plate having an opening / closing part having a lock mechanism (lock means). At this time, the cover body is layered to be separable from the structure.
FIG. 1 is an external perspective view showing a modeling apparatus 100 of the present embodiment.
In the figure, there is shown a modeling chamber 50 that houses the modeling unit 10, the plate 20, the stage 30, a camera unit (not shown), and a code writing unit (not shown). Further, a modeling chamber door 51, an operation display unit 60, a cartridge housing unit 70, and a work chamber 80 are shown.

  The modeling apparatus 100 according to the present embodiment includes a system control unit 101 (see FIG. 2) as a control unit configured by a CPU (processor), a ROM, a RAM, a user interface unit, a communication unit, and the like. In the system control unit 101, the CPU controls the operation of the modeling apparatus 100 by executing a program stored in a ROM or the like. The operation control program is not necessarily executed by the modeling apparatus 100, and may be executed anywhere in the modeling system.

FIG. 2 is a schematic cross-sectional view showing the modeling unit 10, the plate 20, and the stage 30 of this embodiment.
The modeling unit 10 mainly includes a material layer forming unit 3, an intermediate transfer body 4, and a heating member 6. The material layer forming unit 3 forms the particulate material layer 1 made of a modeling material based on the slice data of a plurality of layers generated from the three-dimensional shape data of the modeling object.
Here, when the additional body is manufactured together with the structure, and the additional body includes the support body and the cover body, the cross-sectional data of the support body and the cross-section data of the cover body are also included in the slice data. For example, when the cover body is used to conceal the appearance and configuration of the structure,
The slice data includes cross-sectional data of the cover body. In this embodiment, the material layer forming unit 3 forms a material layer for one layer made of a modeling material using an electrophotographic process. Hereinafter, an example in which the material layer forming unit 3 uses an electrophotographic process will be described. However, the present invention can also be applied to cases where other methods such as an inkjet process are used.

  The intermediate transfer body 4 is an endless belt-like transport body that sequentially receives the material layer 1 formed by the material layer forming unit 3 at the transfer position 7 and carries the material layer 1 and transports it to a predetermined position. The intermediate transfer body 4 is stretched by a drive roller 5a having a drive motor and a driven roller 5b whose tilting axis can be tilted by a drive system (not shown) to correct the meandering of the intermediate transfer body 4. Yes. Each of the driving roller 5a and the driven roller 5b is formed in a crown shape in which the central side is slightly higher than the both end sides in the rotation axis direction in order to prevent the intermediate transfer body 4 from meandering.

  As will be described in detail later, the plate 20 is a substrate having a laminated surface 20 a that holds a model 2 that is produced by laminating the material layers 1, and is detachably held on the stage 30. The heating member 6 is arranged on the inner peripheral side of the intermediate transfer body 4, is movable in the Z direction (height direction), and is temperature-controlled to heat and melt the material layer 1 on the intermediate transfer body 4. It is. The heating member 6 has a heating surface (pressure surface) 6 a that can contact the inner peripheral surface of the intermediate transfer body 4 at the stacking position 8.

  The material layer 1 formed in the material layer forming unit 3 is transferred to the intermediate transfer body 4 at the transfer position 7 and is conveyed in the direction of the arrow 9 in the drawing by the rotation of the driving roller 5a. When the material layer 1 is transported to the predetermined stacking position 8, the transport operation of the material layer 1 by the intermediate transfer body 4 is stopped. The material layer 1 carried on the surface (outer peripheral surface) of the intermediate transfer body 4 is sandwiched between the laminated surface of the plate 20 or the shaped article 2 on the laminated surface and the heating member 6 at the lamination position 8. Lamination is performed.

Next, the plate 20 detachably housed on the stage 30 in the modeling chamber 50 and serving as a modeling substrate for the modeled object will be described.
3A and 3B are schematic perspective views showing the plate 20. 3A shows a state in which the opening / closing portion of the plate 20 is closed, and FIG. 3B shows a state in which the opening / closing portion of the plate 20 is opened.
The plate 20 is formed of an upper frame body 21 and a lower box body 22. The upper frame body 21 and the lower box body 22 are configured to be able to open and close the plate 20 by mutually connecting the edges of the upper frame body 21 and the lower box body 22 with an opening / closing part (connecting part) 26 such as a hinge. Here, the upper frame 21 corresponds to the second plate, and the lower box 22 corresponds to the first plate.

As shown in FIG. 3B, a lock claw 23 is provided at a substantially central position of the upper frame body 21 of the plate 20. The lock claw 23, together with a stopper (not shown) provided on the lower box body 22 side, keeps the upper frame body 21 closed, thereby restricting relative movement between the upper frame body 21 and the lower box body 22. To do. In the present embodiment, a lock mechanism capable of locking the upper frame body 21 and the lower box body 22 in a state where such relative movement is restricted is provided. Since the locking mechanism locks the upper frame body 21 and the lower box body 22, the plate 20 can be locked in a state where the upper frame body 21 is closed.
Further, the lock mechanism of the present embodiment has a locking input unit 24 and an unlocking input unit 25. In the present embodiment, the locking input unit 24 and the unlocking input unit 25 are disposed on the outer side surface of the lower box 22.

The plate 20 is locked by inputting a preset code (information such as a number to be locked) input from the locking input unit 24 from the locking input unit 24. Then, the plate 20 is unlocked by inputting an unlocking code that is the same as the locking code or set corresponding to the locking code from the unlocking input unit 25.
In addition, the opening / closing method of the opening / closing part of the plate 20 may be other methods such as a method of cutting a groove and sliding in addition to a hinge as illustrated. Moreover, the structure which the upper frame 21 and the lower box 22 isolate | separate separately may be sufficient, and the independent member may be sufficient as the upper frame 21 and the lower box 22, respectively. In addition, various mechanisms corresponding to the opening / closing method can be adopted as the lock mechanism.

Here, the form using the means which transmits / receives various signals is illustrated as a locking mechanism.
First, a method for locking the lock mechanism will be described. As a method for locking the lock mechanism, for example, the following well-known techniques can be employed. That is, the locking input unit 24 includes a receiver that receives a signal conveyed by electromagnetic, optical beam, or ultrasonic waves. When the receiver receives the signal, the locking mechanism is extended by the driving mechanism to lock the opening / closing part. The received signal is encoded by the system control unit 101, and this information (locking code) is recorded in the memory. The code writing unit of the modeling apparatus main body includes a transmitter that transmits electromagnetic waves, optical beams, or ultrasonic waves received by the receiver.
When unlocking, the unlocking code input from the unlocking input unit 25 is compared with the above-described locking code recorded in the memory. Retract and unlock.

Next, a modeling service system including the modeling apparatus of this embodiment will be described.
FIG. 4 is a system diagram illustrating a configuration example of the modeling service system 200.
The modeling service system 200 includes a modeling apparatus 100, a server 202 connected to the modeling apparatus 100 via a network 201, and an orderer terminal 203.
The orderer terminal 203 is a computer in which an application program for 3D modeling ordering is installed, and functions as an ordering data creation device that generates ordering data for ordering modeling of a modeled object.

The order data includes three-dimensional shape data indicating the three-dimensional shape of the modeling object, a plate locking code, a desired delivery date, and other communication items. Moreover, based on the three-dimensional shape data, it is processed into slice data for each layer as layered data used in the modeling apparatus 100. The slice data includes the following data. For example, when a cover body is used to conceal the appearance of the structure (see FIG. 6B), the slice data includes cross-sectional data of the cover body. That is, when the additional body includes the support body and the cover body, the slice data includes the cross-section data of the support body and the cross-section data of the cover body.
The processing to slice data is performed by an application program for 3D modeling ordering installed in the orderer terminal 203 (information processing by the application program is specifically realized using hardware resources such as a CPU and a memory). )

FIG. 5 is a flowchart for explaining the flow of the modeling service.
The modeling apparatus 100 of the present embodiment or the server 202 connected to the modeling apparatus 100 displays a home page for accepting a modeling request on the network 201 (step S501). When the orderer makes a modeling request on the homepage (step S502), the modeling apparatus 100 of the present embodiment stores and manages the orderer's modeling request as a modeling job (step S503). The modeling job includes order data and attribute information held in association with the order data. The attribute information includes ordering data identification information, ordering data transmission / reception date / time information, information about the delivery date of the modeled object, information about the footprint of the modeled object (top projection shape / area), orderer identification information, etc. It is.

The modeling apparatus 100 also displays the orderer so that the application program for ordering the three-dimensional modeling can be downloaded (step S504).
The modeling apparatus 100 also creates a modeling plan based on two or more modeling jobs (step S505). Here, the modeling plan refers to assignment of the plate 20 for collectively performing modeling jobs, arrangement of the plate 20 on the stage 30, calculation of modeling start / end scheduled times, and the like.

When the modeling start time arrives (step S506), the modeling apparatus 100 confirms whether the setting in the modeling chamber 50 is ready and other preparations (step S507), and requests data from each orderer terminal 203 ( Step S508).
Then, the modeling room door 51 is locked (step S509), each plate is locked with the received locking code (step S510), and then layered modeling is performed on each plate based on slice data for each layer. (Step S511). The slice data for each layer is erased from the modeling apparatus 100 when the modeling of the layer is completed (step S512).

When the modeling process for all modeling jobs is completed (step S513), the modeling chamber door 51 is unlocked (step S514), and the operator is notified (step S515).
Here, the reason why the modeling room door 51 is locked in step S509 is to prevent access to a modeled object that is not covered by the container during the manufacturing process. However, there may be a situation where the modeling chamber door 51 is unlocked before the modeling is completed, such as when an error occurs. In such a case, for example, an additional process for concealing the modeled object may be provided such that the modeling material is uniformly laminated on the modeled object being produced.

6A to 6C illustrate a state in which the structure 2a and the cover body 2b are layered on the plate 20 in the stage 30 in the modeling chamber 50 after being locked to the plate 20 in the modeling apparatus 100 of the present embodiment. FIG.
FIG. 6A shows a state immediately after the production of the model 2 is started on the plate 20. 6A, when layered modeling of the model 2 is started, layered modeling of the structure 2a is performed on the layered surface 22a of the lower box 22 of the plate 20, and the layered surface 21a of the upper frame 21 of the plate 20 is performed. The layered modeling of the cover body 2b is performed on the top.
FIG. 6B shows a state in which the structure 2a and the cover body 2b are layered.
FIG. 6C shows the model 2 in a state where the production operation of the model 2 is completed and the cover 2b completely covers the structure 2a. In addition, the part represented with the dotted line in FIG. 6C is a part which cannot actually be visually recognized from the cover body 2b outer side. The space between the structure body 2a and the cover body 2b is appropriately filled with a support body, but the illustration is omitted.

Thus, in this embodiment, the layered modeling of the structure 2a is performed on the layered surface 22a of the lower box 22 of the plate 20, and the layered modeling of the cover body 2b is performed on the layered surface 21a of the upper frame 21 of the plate 20. Done.
In the molded article 2 that reaches the orderer, the structure 2a is covered with the cover 2b. The orderer opens the plate 20 and separates the upper frame body 21 and the lower box body 22, so that the structure 2 a formed on the lower box body 22 is removed from the cover body 2 b formed on the upper frame body 21. It can be easily taken out.

Here, it becomes possible to easily take out the structure 2a formed on the lower box 22 from the cover body 2b formed on the upper frame 21, so that it reaches the ordering party, There is a concern that a person other than the orderer can learn the appearance and structure of the structure 2a.
Therefore, in this embodiment, a lock mechanism that locks the opening / closing portion of the plate 20 in the closed state is provided, and the structure 2a and the cover body 2b that covers the structure 2a are produced on the locked plate 20. It was. In the manufactured model 2, the structure 2 a is covered with the cover body 2 b, and the space between the structure 2 a and the cover body 2 b is filled with a support body. For this reason, in order to know the appearance and configuration of the structure 2a, there is no other way than unlocking the opening / closing part of the plate 20 or removing the support body by destroying the cover body 2b. Therefore, if the unlocking code is managed secretly, it becomes extremely difficult for a person other than the orderer to know the appearance and configuration of the shaped article 2. In addition, once unlocked, the opening / closing part of the plate 20 cannot be locked without entering the locking code again. Therefore, even if unlocked by a person other than the orderer, It becomes clear. Needless to say, even when the cover body 2b is destroyed, this is apparent to the orderer.

<Example 2>
Example 2 will be described below. In the present embodiment, configurations and processes different from those in the first embodiment will be described, and descriptions of configurations and processes similar to those in the first embodiment will be omitted.
The present embodiment is characterized in that a locking input portion for locking the locking mechanism of the plate 20 is provided at a location covered by the cover body 2b produced on the plate 20.

FIG. 7 is a view showing the plate 20 of the present embodiment.
In the present embodiment, the lock input unit 24 is disposed on the laminated surface 22a of the lower box 22 of the plate 20, as shown in FIG. When the locking input portion 24 is disposed on the lamination surface 22a, it is preferable that the locking input portion 24 is disposed at a position where the locking input portion 24 does not interfere with the intermediate transfer body 4 when the material layer 1 is laminated. For example, the locking input part 24 is good to be arrange | positioned so that it may be settled in the recessed part provided in the lamination | stacking surface 22a. In FIG. 7, the laminated surface 22 a and the locking input unit 24 are shown to be substantially flush with each other. However, when the recessed portion is provided, the cover and the laminated surface 22 a are provided by providing a cover in the recessed portion. You may make it become substantially flush. Moreover, the arrangement position of the locking input part 24 is not restricted to the lamination | stacking surface 22a of the lower box body 22, It is a place covered with the cover body 2b among the plates 20, ie, the upper frame body 21 and the lower box body 22. I just need it.

With this configuration, when the cover body 2b is formed (stacked) so as to be connected to the upper frame body 21 of the plate 20, the lock input unit 24 cannot be locked from the outside of the cover body 2b. 20 can no longer be locked.
That is, the plate 20 can be locked only before the shaped article 2 is produced thereon.
Assuming that the plate 20 can be locked even after the fabrication of the model 2 is completed and the cover body 2b is formed, the following situation may occur. That is, a modeling service provider or the like prepares a model 2 including the structure 2a and the cover 2b without locking the plate 20, takes out the model 2 after the preparation is finished, and opens the cover 2b. Know the appearance and structure of the structure 2a. Then, if the cover body 2b is closed and the plate 20 is locked, it becomes possible to conceal from the orderer that the outer appearance and structure of the structure body 2a have been obtained.
Such a situation can be prevented by the configuration of the present embodiment.

  As described above, according to the present embodiment, when the shaped article 2 produced on the unlocked plate 20 reaches the orderer, the appearance and configuration can be known to a person other than the orderer. This has the effect of making it clear to the orderer.

<Example 3>
Example 3 will be described below. In the present embodiment, configurations and processes different from those in the first and second embodiments will be described, and description of configurations and processes similar to those in the first and second embodiments will be omitted.
The present embodiment is characterized in that the structure 2a and the cover 2b are manufactured so as to be in contact with each other or close to each other.

The shape of the cover body 2b and the arrangement (direction / position) of the structures 2a in the cover body 2b are determined as described above. That is, in the orderer terminal 203, the three-dimensional modeling ordering application program downloaded from the modeling apparatus 100 is determined based on the three-dimensional shape of the structure 2a and the types of available plates.
Therefore, in the present embodiment, the footprint (upper surface projection shape) of the structure 2a is compared with the planar shape of each layer, and the cover is provided so that the structure 2a and the cover 2b are in contact with or close to each other in the layer where the contours overlap most. The shape of the body 2b was decided. In addition, the method of determining the shape of the cover body 2b is not restricted to this.
Thereby, it becomes possible to produce the shaped article 2 so that the structure 2a and the cover body 2b are in contact with each other or close to each other while suppressing the size of the cover body 2b.

As described above, when the model 2 is produced so that the structure 2a and the cover 2b are in contact with or close to each other, even if the cover 2b is destroyed, the structure 2a can be destroyed at that time. High nature.
That is, even if a person other than the orderer destroys the cover body 2b in an attempt to obtain the appearance and configuration of the structure 2a in the process in which the manufactured model 2 is delivered to the orderer, the structure Since 2a itself is also destroyed, it is considered difficult to know the appearance and configuration of the structure 2a.
That is, according to the present embodiment, it is possible to make it more difficult for a person other than the orderer to know the appearance and configuration of the structure 2a.

<Example 4>
Example 4 will be described below. In the present embodiment, configurations and processes different from those in the first to third embodiments will be described, and description of the same configurations and processes as in the first to third embodiments will be omitted.
In this embodiment, the structure 2a and the cover body 2b are made of a common modeling material.

As described above, as the structural material, thermoplastic resin such as PE (polyethylene), PP (polypropylene), ABS, PS (polystyrene), metal material, ceramic material, and the like are used. It can be used as appropriate according to the purpose.
Also in the production of the cover body 2b, it is possible to use the same structural material as described above.
Here, when the structural body 2a and the cover body 2b are made of a common modeling material, the partial strength of the structural body 2a and the cover body 2b can be made equal, so that the structural body when the cover body 2b is destroyed. It becomes possible to increase the possibility that 2a is also destroyed.
In addition, when the cover body 2b and the structure body 2a are destroyed, fragments of the structure body 2a and the cover body 2b made of a common modeling material will be lost, and the appearance and structure of the structure body 2a can be changed from the fragments. It is also difficult to estimate.

  That is, according to the present embodiment, it is possible to make it more difficult for a person other than the orderer to know the appearance and configuration of the structure 2a.
