1. A description of the configuration of a three-dimensional printer

1 is a schematic view showing a configuration of a general three-dimensional printer.

1, a general three-dimensional printer includes a working housing 20 in which a photopolymerizable resin (r) is accommodated and provided with a target printing space, a fixing device 20 which moves up and down in a working housing 20, A projector 40 for irradiating light onto the upper side of the molding plate 30 with a photo-curing resin, and a panel P for forming a curing pattern.

Here, the printing of the object S in the form of a laminate is realized in which the shaping plate 30 is moved upward under the control of the three-dimensional printer to realize the curing of the photo-curing resin.

2. Explanation of how to print a three-dimensional printer

3 is a flowchart illustrating a printing method of a three-dimensional printer according to another embodiment of the present invention. FIG. 4 is a flowchart illustrating a method of printing a three-dimensional printer according to an embodiment of the present invention. Dimensional printer according to the embodiment of the present invention.

2 to 4, a printing method of a three-dimensional printer according to the present invention includes a file producing step S10, a file processing step S20, a heterogeneous material arranging step S25, and a printing step S30.

That is, the printing method of the three-dimensional printer according to the present invention includes a file producing step (S10) of producing a three-dimensional modeling file for the object S; A file processing step (S20) of adding stack setting information to the modeling file; (S30) of applying the information generated from the file processing step (S20) to a three-dimensional printer to cure and laminate the photocurable resin (r) with the light providing means to print the object (S) (S) supported on the molding plate (30) or the molding plate (30) by the dissimilar material (10) of a material different from the photo-curing resin (r) before or during the printing step (S30) And a heterogeneous material disposing step (S25) for disposing or inserting the heterogeneous material.

Here, the file production step S10 is a step of modeling the information obtained by the three-dimensional scanning of the object S to produce a modeling file so that the modeling file can be applied to the three-dimensional printer, and can be acquired through an electronic terminal such as a scanner and a PC.

The file processing step S20 is a step of creating a three-dimensional image for printing the object S in which the cured resin and the dissimilar material 10 are combined with each other by merging various setting information into the modeling file obtained in the file producing step S10 And the stack setting information is added to control the operation of the printer. The stack setting information is used to control the intensity of the projector, the stack thickness setting, the print pattern control, the temporary stop and restart setting of printing, and the robot arm control And the like.

Here, the dissimilar material 10 may be made of a metallic material such as copper, aluminum, or thorium or a synthetic resin material such as plastic, and the material of the dissimilar material 10 may be selected from materials different from the photocurable resin (r) have.
