이에 따라, 광원(130)으로부터의 광이 광연결부(140)을 통과하여 3D프린팅재료로 방사되므로, 광의 스팟의 크기가 조절되어 3D출력물의 품질을 제어할 수 있다.Accordingly, since the light from the light source 130 passes through the optical connection unit 140 and is emitted to the 3D printing material, the size of the spot of the light is adjusted to control the quality of the 3D output.

도 5는 본 발명의 또다른 실시예에 따른 3D프린터용 광원모듈의 단면도이다. 본 실시예에 따르면, 회전축(110); 회전축(110)과 연결되어 회전되는 광방사부(120); 및 3D프린팅재료를 향하여 광을 방사하는 광원으로서, 광방사부(120)와 이격되어 위치하고, 광방사부(120)와 광섬유(151)로 연결된 광원;을 포함하는 3D프린터용 광원모듈(100)이 제공된다.5 is a cross-sectional view of a light source module for a 3D printer according to another embodiment of the present invention.

즉, 3D프린팅재료(210)이 채워져있는 3D프린팅재료부(200)에 3D프린터용 광원모듈(100)을 통해 원하는 형상에 따라 필요한 광원에만 전원을 인가한 후, 회전축(110)을 1회 회전시킨다. 그 후 3D프린팅재료(210)을 추가하여 프린팅할 추가적인 층을 만든 후 원하는 형상에 대한 필요한 광원을 작동시키고 1회 회전한다. 다시 3D프린팅재료(210)을 추가하여 프린팅할 추가적인 층을 형성한다. 이와 같은 단계를반복하면 원하는 3D 프린팅 출력물을 얻는다. 3D프린팅재료대신 플라스틱 파우더나 금속 파우더 등이 사용될 수 있다.That is, after power is applied to the 3D printing material unit 200 filled with the 3D printing material 210 according to the desired shape through the light source module 100 for the 3D printer, power is applied only to the required light source, and then the rotation shaft 110 is rotated once. make it After that, the 3D printing material 210 is added to create an additional layer to be printed, and then the necessary light source for the desired shape is activated and rotated once. Again, the 3D printing material 210 is added to form an additional layer to be printed. Repeat these steps to obtain the desired 3D printed output. Instead of the 3D printing material, plastic powder or metal powder may be used.

도 7은 본 발명의 또다른 실시예에 따른 3D프린터의 모식도이다. 3D프린터용 광원모듈(100)은 도 6의 실시예에서와 달리 3D프린팅재료부(200)의 하부에 위치할 수 있다. 또한, 도 8을 참조하면, 3D프린팅재료부(200)에도 3D프린팅재료부 회전축(220)을 구비하여, 3D프린팅재료부(200)가 회전을 하는 방식으로 3D프린팅을 수행할 수 있다.7 is a schematic diagram of a 3D printer according to another embodiment of the present invention. The light source module 100 for the 3D printer may be located under the 3D printing material unit 200 unlike in the embodiment of FIG. 6 . In addition, referring to FIG. 8 , the 3D printing material unit 200 also includes a 3D printing material unit rotation shaft 220 , so that the 3D printing material unit 200 rotates to perform 3D printing.

도 9는 본 발명의 또다른 실시예에 따른 3D프린터의 모식도이다. 본 실시예에 따른 3D프린터는 회전축(110)과 연결된 선형스테이지부(160);를 더 포함할 수 있다. 3D프린터용 광원모듈(100)은 곡선에 대한 정밀도는 높으나 사각형태의 형상에서는 정밀도가 떨어질 수가 있어 회전축(110) 위에 선형스테이지부(160)를 구비하여 필요에 따라 회전과 선형을 병행하여 출력물을 제조할수 있다.9 is a schematic diagram of a 3D printer according to another embodiment of the present invention. The 3D printer according to the present embodiment may further include a linear stage unit 160 connected to the rotation shaft 110 . The light source module 100 for a 3D printer has high precision for curves, but may have poor precision in a rectangular shape. Therefore, a linear stage unit 160 is provided on the rotating shaft 110 to rotate and linearly output output in parallel as needed. can be manufactured
