Abstract

The manufacturing apparatus (1) for three-dimensional moldings is provided with a molding block (20), a tag-supplying block (30) and a control unit (12). The molding block (20) is a molding device for molding a three-dimensional object by successively layering molding material layer by layer. The tag-supplying block (30) is a tag-supplying device for supplying a wireless communication tag to a specified position. The control unit (12) causes the tag-supplying block (30) to supply the wireless communication tag to the specified position of the molding material during layering of the molding material by the molding block (20) so that the wireless communication tag is embedded inside the three-dimensional molding that is obtained by layering the molding material.

the controller makes the tag feeder feed the wireless communication tag to the predetermined position in the modeling material in a middle of the stacking of the modeling material by the modeler such that the wireless communication tag is embedded inside the 3D-modeled object formed of the stacked layers of the modeling material.

2. The apparatus of claim 1, wherein

the controller calculates an embedding position at which to embed the wireless communication tag inside the 3D-modeled object based on 3D shape data of the 3D-modeled object and shape data of the wireless communication tag, and

the controller has the wireless communication tag fed in a middle of the stacking of the modeling material such that the wireless communication tag is embedded at the calculated embedding position.

3. The apparatus of claim 2, further comprising:

a storage that stores shape data for a plurality of wireless communication tags,

wherein

the controller

selects a wireless communication tag with a shape that can be embedded referring to the storage based on the 3D shape data of the 3D-modeled object, and calculates the embedding position for the selected wireless communication tag.

4. The apparatus of claim 1, wherein

the controller merges layer data obtained from 3D shape data of the 3D-modeled object with data of a space for embedding the wireless communication tag inside the 3D-modeled object, thereby to re-construct layer-by-layer data of the 3D-modeled object, and

the modeler stacks layers of the modeling material based on the re-constructed layer-by-layer data.
