  In FIG. 1, although an example of the external appearance of the three-dimensional modeling apparatus 36 is shown, the three-dimensional modeling apparatus 36 indicates the modeling method, the range of the size of a modeled object that can be modeled, and the type of material (filament) to be applied. Depending on the elements it contains, its appearance and size vary.

  1 and 2, three three-dimensional modeling apparatuses 36 are illustrated, but two or four or more types of three-dimensional modeling apparatuses 36 may be connected and selectable depending on an object to be modeled. Good.

  In the three-dimensional modeling apparatus 36, materials (materials) that can be adapted for modeling differ depending on the type of each modeling method.

FIGS. 3A to 3G show an example of the relationship between the types and functions of modeling methods and the materials that are compatible with each modeling method.
(1) Binder Injection Method As shown in FIG. 3 (A), the binder injection method three-dimensional modeling apparatus 36A is a method in which a liquid binder 50 is injected onto the powder bed 52 and selectively solidified. . Examples of materials include gypsum, ceramics, sand, calcium, and plastic.

Examples of materials include ABS (acrylonitrile butadiene styrene resin), PLA (polylactic acid), nylon 12, PC (polycarbonate), and PPSF (polyphenylsulfone).
(4) Material Injection Method As shown in FIG. 3D, the material injection method three-dimensional modeling apparatus 36D is a method in which droplets 62 of material are injected and selectively deposited and solidified. The three-dimensional modeling apparatus 36D is a typical modeling method based on the ink jet method. Examples of materials include UV curable resin, fat, wax, and solder.
(5) Powder Bed Melt Bonding Method As shown in FIG. 3E, the powder bed melt bonding type three-dimensional modeling apparatus 36E selectively uses a region 66 coated with powder by thermal energy irradiated from a laser 66. This is a method of melt-bonding. Examples of materials include engineering plastic, nylon, and metal.
(6) Sheet Lamination Method As shown in FIG. 3F, the sheet lamination type three-dimensional modeling apparatus 36F is a method in which a sheet-like material 68 is adhered. Examples of materials include paper, a resin sheet, and an aluminum sheet.
(7) Liquid Tank Photopolymerization Method As shown in FIG. 3G, the liquid tank photopolymerization type three-dimensional modeling apparatus 36G selectively selects a liquid photocurable resin 72 stored in the tank 70 by photopolymerization. This is a curing method. An example of the material is UV curable resin.

  In addition, seven types of three-dimensional modeling apparatuses 36A to 36G having different modeling methods shown in the above (1) to (7) are selectively used in the three-dimensional modeling apparatuses 36 (1) to (1) to (1) to ( n). Moreover, you may select the three-dimensional modeling apparatus of the modeling system different from the modeling system shown to said (1)-(7).

  In the three-dimensional modeling apparatus 36, the relationship (material-modeling system conformity table) between the material and the modeling method (the three-dimensional modeling apparatus (1) to (7) above) that can be adapted to the material is a model order management. It is stored in the hard disk 34 (see FIG. 2) of the control device 14. For example, when a material is specified from the ordering party, the material-modeling method compatibility table is read out and a suitable modeling method is selected.

  Here, when receiving a three-dimensional modeling order from the ordering source (that is, receiving an order), the modeled object order management control device 14 selects a modeling method that can be adapted to the material based on the specified material, To do. Note that delivery date and cost may be included as factors for selecting the modeling method.

  By the way, in the three-dimensional modeling apparatus 36, it models fundamentally based on three-dimensional modeling data.

  When duplicating an existing model, the modeling material is specified (or specified), and the captured image data obtained by photographing the model from a plurality of predetermined viewpoints is analyzed to generate three-dimensional model data. . At this time, if a molded object partially damaged, for example, a coffee cup is missing and there is a missing part, the shooting target becomes an incompletely shaped object, and it is difficult to generate 3D modeling data as a finished product Become.

  Therefore, in the present embodiment, the shape of the missing part is predicted from the shape of the incompletely shaped object, and three-dimensional modeling data is generated to form a finished product including the missing part or the missing part.

  FIG. 4 is executed by the modeling object order management control device 14 (see FIG. 2) according to the present embodiment, and executes modeling object order management control by a modeling request specialized for restoration of incomplete modeling objects. It is a functional block diagram. Note that each block in FIG. 4 does not limit the hardware configuration of the model order management control device 14.

  Moreover, the procedure of the process based on each functional block of FIG. 4 is an example, and the process procedure for executing the model order management control is not limited. That is, from the shape of the imperfectly shaped object, the shape of the missing part is predicted to generate three-dimensional modeling data, and if the processing procedure for shaping the finished product including the missing part or the missing part is established, It may be a processing procedure.

  As shown in FIG. 4, the reception unit 74 receives a modeling request (here, a modeling request for restoring an incompletely modeled object).

  The information on the modeling request is classified into shape information, attribute information, and management information.

  The shape information includes the minimum necessary information among the appearance photographing data of the imperfectly shaped object, the photograph data before the defect, the sketch data drawn by the modeling client, and the tomographic data of the imperfectly shaped object. The tomographic data may be both or either of the longitudinal section and the transverse section of the imperfectly shaped object. Furthermore, the finer the resolution (number of layers) of a fault, the finer the accuracy, the higher the accuracy, but it may be determined in consideration of the delivery date, cost, etc. described later.

  The attribute information includes the minimum necessary information among the type (article type), material (generated material), hardness, and surface roughness of the article.

  The management information includes the minimum necessary information among the modeling target, delivery date, cost, and designated material. The modeling target is information that determines whether the target of the modeling request is a missing part or a finished product obtained by synthesizing the missing part with an incompletely shaped object. The designated material may be changed from, for example, an original material made of ABS resin to UV curable resin.

  The reception unit 74 is connected to the shape information acquisition unit 76, the attribute information acquisition unit 78, and the management information acquisition unit 80.

  The shape information acquisition unit 76 acquires shape information from the reception unit 74. The attribute information acquisition unit 78 receives attribute information from the reception unit 74. The management information acquisition unit 80 acquires management information from the reception unit 74.

  The shape information acquisition unit 76 is connected to the incompletely shaped object modeling data generation unit 82. The incompletely shaped object modeling data generating unit 82 generates 3D object data of an incompletely shaped object, that is, a shaped object in a partially missing state, using the shape information.

  In addition, the shape information acquisition unit 76 and the attribute information acquisition unit 78 are each connected to the missing portion shape prediction unit 84.

  The missing part shape prediction unit 84 predicts the shape of the missing part based on the shape information and the attribute information, and sends it to the missing part modeling data generation unit 86.

  The missing part modeling data generation unit 86 generates three-dimensional modeling data from the predicted missing part shape and sends it to the correction unit 88.

  Here, the modeling format data generated by the incompletely modeled object modeling data generation unit 82 and the missing part modeling data generation unit 86 is not limited to polygon data, and voxel data stored in a FAV (fabricatable voxel) format is applied. Is possible.

(Outline of FAV format)
In the FAV format, not only the external shape (polygon data) of the 3D model data but also various attributes such as the internal structure, the material used, and the bonding strength are retained. Regardless of the appearance and inside of the 3D model data, it is guaranteed that it can be designed thoroughly, precisely and precisely, and can be saved as data, as the designer thought.

  The FAV format is based on voxel data.

  A voxel is a three-dimensional pixel value. An object is formed by three-dimensionally arranging voxels having three-dimensional pixel values so as to form an image by arranging pixels having two-dimensional pixel values in a plane.

  That is, the FAV format is 3D model data having the following conditions.

  (Condition 1) Regardless of the inside or outside of the 3D model data, information necessary for manufacturing such as shape, material, color, bonding strength, etc. must be clearly defined for each three-dimensional position.

  (Condition 2) Design (CAD), analysis (CAE), and inspection (CAT) of 3D model data can be performed in a unified and bidirectional manner without data conversion.

  As shown in FIG. 4, the correction unit 88 takes in the three-dimensional modeling data of the incomplete modeling object from the incomplete modeling object modeling data generation unit 82, and performs the missing part modeling data received from the missing part modeling data generation unit 86. To correct the continuity of the joint. Specifically, the missing portion modeling data is corrected so that the coordinates of the joint between the incompletely shaped object and the missing portion shape coincide on the three-dimensional coordinates.

  The correction unit 88 is connected to the modeling data construction unit 90. The modeling data construction unit 90 takes in information related to the modeling target from the management information acquisition unit 80, and is finally designated as a target to be modeled (finished product (original modeled object with the missing part repaired) or missing part) 3D modeling data is constructed and sent to the modeling method selection unit 92.

  The modeling method selection unit 92 is connected to the management information acquisition unit 80 and the operation information reading unit 94. The operation information reading unit 94 acquires the current operation information (operation status) of the three-dimensional modeling apparatus 36 from the modeling apparatus management unit 96.

  The modeling method selection unit 92 selects a modeling method from the management information (delivery date and cost, designated material) received from the management information acquisition unit 80 and the operation information of the 3D modeling apparatus 36 received from the operation information reading unit 94. The data is sent to the modeling instruction unit 98.

  In the modeling instruction unit 98, modeling using the 3D modeling apparatus 36 selected by the modeling method selection unit 92 based on the 3D modeling data constructed by the modeling data construction unit 90 is performed on the modeling apparatus management unit 96. Instruct.

  The operation of the present embodiment will be described below with reference to the flowcharts of FIGS.

  FIG. 5 is a flowchart illustrating a control routine specialized in a restoration modeling request for an incompletely shaped object in the modeling request according to the present embodiment.

  In explaining the flow of the flowchart of FIG. 5, as an imperfectly shaped object 99, a cup (coffee cup, tea cup, vase, etc.) that stores a fluid will be described as an example. Assume that a part is missing and the missing part 99A is lost.

  In step 100, the shape information of the imperfectly shaped object 99 is acquired, and then the process proceeds to step 102, the attribute information of the imperfectly shaped object 99 is acquired, and the process proceeds to step 104.

  In step 104, the shape of the missing portion 99A is predicted from the shape information and attribute information of the imperfectly shaped object 99.

  In the next step 106, three-dimensional modeling data of the missing portion 99A is generated, and the process proceeds to step 108.

  In step 108, the three-dimensional modeling data of the missing portion 99A is corrected based on the continuity between the imperfectly shaped object 99 and the missing portion 99A. That is, the three-dimensional modeling data of the missing portion 99A is set so that the coordinates of the joint portion between the incompletely shaped product 99 and the missing portion 99A coincide on the three-dimensional coordinates of both the incompletely shaped product 99 and the missing portion 99A. to correct.

  In the next step 110, the modeling object requested for modeling is determined. That is, as a modeling request, when requesting modeling of the finished product 99B in which the missing part 99A is combined with the incompletely shaped object 99, and joining the incompletely shaped object 99 with another means such as bonding with an adhesive or the like. Therefore, there is a case where the modeling of the missing portion 99A is requested.

  If it is determined in step 110 that the modeling of the finished product 99B has been requested, the process proceeds to step 112, where the three-dimensional modeling data of the incomplete modeling object 99 is complemented with the three-dimensional modeling data of the missing portion 99A. Then, the three-dimensional modeling data of the finished product 99B is generated, and the process proceeds to step 114.

  If it is determined in step 112 that modeling of the missing portion 99A has been requested, the three-dimensional modeling data of the missing portion 99A has already been generated, and the process proceeds to step 114.

  In step 114, the modeling by the three-dimensional modeling apparatus 36 is instructed, and this routine ends.

  Next, FIG. 6 is a flowchart illustrating a control routine for executing modeling by the three-dimensional modeling apparatus 36 after the modeling request three-dimensional modeling data is determined according to the present embodiment.

  In step 120, it is determined whether or not there is a modeling instruction. Here, the modeling instruction corresponds to the modeling instruction in step 114 of FIG.

  If a negative determination is made in step 120, it is determined that there is no modeling instruction, and this routine ends.

  If the determination in step 120 is affirmative, it is determined that there has been a modeling instruction, the process proceeds to step 122, and the three-dimensional modeling data to be modeled is read out. That is, when the modeling target is the finished product 99B, the three-dimensional modeling data of the finished product 99B is read, and when the modeling target is the missing portion 99A, the three-dimensional modeling data of the finished product 99B is read.

  In the next step 124, management information is acquired, and then the process proceeds to step 126, the operation information of the 3D modeling apparatus 36 is read, and the process proceeds to step 128.

  In step 128, the 3D modeling apparatus 36 is selected based on the management information and the operation information, and then the process proceeds to step 130 to control the modeling by the selected 3D modeling apparatus 36, and this routine ends.

(Modification)
In the present embodiment, the shape of the missing portion 99A is predicted from the imperfectly shaped object 99, and correction is performed to take the continuity of the joint surface. Further, for example, the imperfectly shaped object 99 and the missing portion 99A When the attribute (type) of the finished product 99B can be determined by the joining simulation, the 3D modeling data may be corrected according to the feature of the attribute.

  For example, after predicting the shape of the missing portion 99A shown in FIG. 7B from the imperfectly shaped object 99 shown in FIG. 7A, the type of the finished product 99B is determined as shown in FIG. 7C. When it is found that the “handle” 99C exists in the missing portion 99A, it can be corrected to the three-dimensional modeling data in which the “handle” is added to the missing portion 99A as shown in FIG. Become.
