The data storage unit 301 is a data storage area of the memory 202 or the HDD 203, and stores modeling data (model data). The acquisition unit 302 acquires the modeling data stored in the HDD 203 or the like. The modeling data is described in a format called STL as shown in Table 1. The STL format is an example, and other modeling formats may be adopted.

The UI control unit 303 displays a screen for editing the divided modeling data and acquires information input from the user. The data generation unit 305 generates divided modeling data from the modeling data of the entire modeled object. Further, the data generation unit 305 embeds in each of the divided modeling data information for assembling the divided modeling object corresponding to the divided modeling data and supporting joining with other divided modeling objects. Generate data.

As the information for supporting the joining, for example, there is the position information of the divided modeling data in the entire modeled object and the information about the joint portion of the divided modeled object. In the divided object after modeling, the surface is processed so that the identification information is specified as the information for supporting the joining. Further, a chip with a memory that can read the information wirelessly may be embedded. In addition, the data generation unit 305 generates a division modeling data list as shown in Table 2, in which each division modeling data and the position information of the division modeling data in the entire modeled object are associated with each other.

The data conversion unit 306 converts the modeling data into control commands used when the modeling device 102 actually models. The control command referred to here is a machine tool command called a G code, and an extended format for a 3D printer is widely used. The transmission / reception unit 304 transmits a control command to the modeling device 102.

The modeling device 102 includes a transmission / reception unit 311 and a modeling control unit 312. The transmission / reception unit 311 receives a control command from the management device 101.

Upon receiving an instruction to generate a plurality of divided objects capable of assembling the object from the modeling data corresponding to one object, the management device performs the following processing. In step S101, the management device 101 generates divided modeling data which is a plurality of model data from the modeling data (model data) of the entire modeled object which is one object. Details of the process in step S101 will be described later with reference to FIG. It is assumed that the modeling data of the entire modeled object is prepared in advance and stored in the HDD 203.

In step S102, the management device 101 adds a joint to each divided modeling data. Details of the process in step S102 will be described later with reference to FIG. In step S103, the management device 101 adds position information to each division modeling data. Details of the process in step S103 will be described later with reference to FIG.

In step S111, the acquisition unit 302 acquires the modeling data stored in the data storage unit 301 (HDD 203 or the like). In step S112, the acquisition unit 302 acquires setting information (setting value) of how to divide the entire modeled object from the HDD 203.

For example, when the entire modeled object is divided into a cube, the length of the side of the cube is acquired as setting information. The setting information may be saved in advance, or the information input by the user may be acquired by the UI control unit 303 and saved in the HDD 203. That is, the user can determine at which part one object is divided and reflect it in the division. At this time, it is possible to use the editing screen (FIG. 15) described later.

The user sees the image displayed in division units and edits the image through the input device 204. The user can finish editing the image of the divided modeling data by pressing the OK button.

Returning to the description of FIG. In step S124, the UI control unit 303 determines whether or not the editing of the image is completed in response to the pressing of the OK button on the editing screen of FIG. When the editing is completed, the process proceeds to step S125. In step S125, the UI control unit 303 saves the edited divided modeling data in the HDD 203. If the UI control unit 303 determines in step S124 that the editing of the image has not been completed, the process of step S123 is continued.

In step S131, the acquisition unit 302 acquires the division modeling data and the position information from the division modeling data list stored in the data storage unit 301. In step S132, the data generation unit 305 adds position information to each division modeling data.

The position information to be added here is, for example, printing a symbol indicating a position such as "1-1-1" on the surface of each divided model with ink of a color different from the surroundings, for surface processing of the divided model. Information to do. In step S133, the UI control unit 303 displays an image editing screen (FIG. 15) of an object formed based on the divided modeling data on the output device 205. The user can see the displayed image and edit the image through the input device 204.

In step S134, the UI control unit 303 determines whether or not the image editing is completed. When it is determined that the editing is completed, the process proceeds to step S135. In step S135, the UI control unit 303 stores the edited divided modeling data in the divided modeling data list of the data storage unit 301. If the UI control unit 303 determines in step S134 that the editing of the image has not been completed, the process of step S133 is continued.

As described above, according to the present embodiment, when one object is divided into a plurality of divided objects that can be assembled, it is possible to generate a divided object that can be easily assembled. For example, from the printed position information, it is possible to determine which position part of the entire modeled object corresponds to the modeled divided modeled object.
