Beschreibung
Zusammenfassung:	The present invention relates to a 3D volumetric printer to reduce optical loss by applying a movable light-transmitting window capable of relative movement inside the water tank and minimizing the unnecessary contact between irradiated visible light and a resin stored in the water tank when manufacturing a molded product by irradiating two-wavelength light to harden the two-wavelength photocurable resin stored in the water tank. 본 발명은 수조에 수납된 2파장 광경화성 레진에 2파장 광을 조사하여 경화시키는 방식으로 성형물 제조 시, 상기 수조 내부에 상대운동이 가능한 이동형 광투과창을 적용하여 조사되는 가시광선과 수조에 수납된 레진과의 불필요한 접촉을 최소화함으로써 광손실을 줄일 수 있도록 한 3차원 체적 프린터에 관한 것이다.
