FIG. 1 is a configuration diagram of a three-dimensional printing system according to an embodiment of the present invention. FIG. 2 shows a three-dimensional molding according to an embodiment of the present invention. FIG. 4 is a flowchart illustrating a three-dimensional printing method according to an embodiment of the present invention.

Referring to FIG. 1, a three-dimensional printing system 100 has a three-dimensional printing mechanism for forming a three-dimensional sculpture by laminating a plurality of layers.

The 3D printing system 100 generates a 3D sculpture on the basis of the 3D model information received from the host apparatus 200, which is generated by the system itself or connected through a communication line.

The host device 200 may be a computing device or a server device. The host device 100 may be a user terminal such as a mobile phone, a tablet PC, or a smart phone. The host device 100 may be an external storage device such as a USB memory or an external hard disk.

The three-dimensional printing system 100 includes a three-dimensional printing control unit 110, a three-dimensional printer 130, and a memory 150. These configurations 110, 130, and 150 may be implemented as a single physical device.

The 3D printing control unit 100 has a function configured to communicate with the host device 200 and is at least partly implemented in hardware so as to allow the 3D printer 130 to operate the entire operation of the 3D printer 130 . The three-dimensional printing control unit 110 generates a print control command based on the three-dimensional model information and outputs the generated print control command to the three-dimensional printer 130.

At this time, the three-dimensional printing control unit 110 generates a three-dimensional molding according to the three-dimensional modeling information and additionally generates a print control command for forming an author identification pattern and outputs the generated command to the three-dimensional printer 130.

The three-dimensional printer 130 sequentially reconstructs a digitized three-dimensional product design, that is, three-dimensional modeling in a two-dimensional section, as if a general printer ejects ink according to a photograph or a document inputted thereto, And a three-dimensional sculpture is formed by stacking the three-dimensional sculpture. The three-dimensional printer 130 performs a process of laminating materials one by one using one or more nozzles (not shown) that eject material such as resin.

The three-dimensional printer 130 can use a technique of forming an object using a plurality of layers made of a material such as plastic or resin, and can utilize an additional manufacturing technique.

3, the three-dimensional printer 130 may generate a three-dimensional sculpture in which the inner space is filled, as shown in FIG. 2, or a three-dimensional sculpture in which a hollow space is formed, as shown in FIG.

The 3D printer 130 forms an engraving identification pattern in a predetermined position in the case of a three-dimensional molding in which the inner space is filled. Here, the engraving is one of engraving techniques, and refers to a technique of engraving letters or figures on the surface of a material. That is, the author identification pattern is formed in a recessed shape at an arbitrary point inside the three-dimensional sculpture as shown in FIG.

In addition, in the case of a three-dimensional molding in which a hollow space is formed in the interior of the three-dimensional printer 130, the three-dimensional printer 130 forms an author identification pattern in a blanket shape at a predetermined position. Here, embossing is one of the engraving techniques, which refers to a technique in which letters or pictures protrude on the surface of a material. That is, the author identification pattern is formed in a protruding shape at an arbitrary point inside the three-dimensional sculpture as shown in FIG.

Here, in the case of a line having a certain thickness for expressing a shape even if a hollow space is formed therein, since the line itself is filled with the inside, the author identification pattern may be formed in a concave shape in the inside of the line .

Therefore, the above-mentioned inside-filled type molding and the inside-empty type molding may refer to the whole three-dimensional molding, but may also mean some points in the three-dimensional molding.

Here, the author identification pattern may be a combination of letters, symbols, figures, numbers, or the like, or may be a code divided into shadows. In the case of a code, it may be a bar code or the like.

The author identification pattern may be formed in a form that can be scanned by pattern detecting means including at least one of an optical detecting means, an ultrasonic detecting means, a radiation detecting means, and a current detecting means.

The memory 150 is for storing the received three-dimensional modeling information or for storing software necessary for the three-dimensional printing controller 110 to control the entire operation of the three-dimensional printer 130.

Here, the author identification pattern information includes position information and pattern information on which the author identification pattern should be inserted on the three-dimensional model.

In this case, the author identification pattern corresponds to a case where a three-dimensional modeling author inputs.

The three-dimensional printing control unit 110 requests the three-dimensional printer 130 to start printing (S103). Then, the three-dimensional printer 130 starts the three-dimensional molding production (S105). That is, the driving for producing the three-dimensional sculpture starts.

The three-dimensional printing control unit 110 generates a print control command according to the three-dimensional modeling information to control the printing operation of the three-dimensional printer 130. At this time, the current output position according to the three-dimensional modeling information is confirmed (S107) It is determined whether it is the author identification pattern insertion position (S109). That is, a plurality of layers are stacked, and it is determined whether the position to be currently stacked according to the three-dimensional modeling information is a position at which the author identification pattern should be printed.

The 3D printing control unit 110 generates a print control command for forming only the 3D modeling information and outputs the generated print control command to the 3D printer 130 (S111). Then, the 3D printer 130 produces a 3D model based on the 3D modeling information according to the print control command (S113). Here, the print control command may include a driving command of the nozzle.

If the 3D printing control unit 110 inserts an author identification pattern, the 3D printing controller 110 generates a print control command to form an author identification pattern in addition to the 3D modeling information, and outputs the generated print control command to the 3D printer 130 (S115). Then, the three-dimensional printer 130 forms a three-dimensional model based on the three-dimensional modeling information and an author identification pattern at a predetermined position in the three-dimensional model according to the print control command (S117).

The three-dimensional printing control unit 110 requests the three-dimensional printer 130 to start printing (S203). Then, the three-dimensional printer 130 performs the three-dimensional molding production start (S205).

The 3D printing control unit 110 checks the author identification pattern information from the memory 150 (S207).

The 3D printing control unit 110 determines a current position to be stacked according to the 3D modeling information received in step S201 (S209), and determines whether the position of the author identification pattern is to be printed (S211).

The 3D printing control unit 110 generates a print control command for forming only the 3D modeling information and outputs the generated command to the 3D printer 130 (S213), if it is not the author ID pattern insertion position. Then, the three-dimensional printer 130 produces a three-dimensional molding based on the three-dimensional modeling information according to the print control command (S215).

If the 3D printing control unit 110 inserts the author identification pattern, the 3D printing controller 110 generates a print control command to form an author identification pattern in addition to the 3D modeling information, and outputs the generated print control command to the 3D printer 130 in operation S217. Then, in step S219, the three-dimensional printer 130 forms a three-dimensional artwork based on the three-dimensional modeling information and an author identification pattern in a predetermined position in the three-dimensional artwork according to the print control command.
