Title
(EN) 3D PRINTER AND 3D PRINTING METHOD
(FR) IMPRIMANTE 3D ET PROCÉDÉ D'IMPRESSION 3D
(KO) 3D 프린터 및 3D 프린팅 방법
Abstract
(EN) Disclosed are a 3D printer and a 3D printing method, which use photo-curable resin to shape output while stacking layers one by one, the 3D printer comprising: an accommodating unit for accommodating the photo-curable resin; a light engine, which is provided below the accommodating unit to provide, to the accommodating unit, a light source for shaping output, and thus cures the photo-curable resin; a plate provided above the accommodating unit in a vertically movable manner to allow the photo-curable resin in single layers to be stacked on the bottom surface thereof while dipped in the photo-curable resin, and thus forms a three-dimensional output; and an inclined elevating member which raises the plate after the stacking of one single layer on the plate is complete, so as to permit stacking of the next single layer while separating the plate from the bottom surface of the accommodating unit, and which raises and lowers the plate while adjusting the inclination angle of the plate.
(FR) La divulgation concerne une imprimante 3D et un procédé d'impression 3D, qui utilisent une résine photodurcissable pour mettre en forme un produit en sortie tout en empilant des couches une par une, l'imprimante 3D comprenant : une unité de réception servant à recevoir la résine photodurcissable; un moteur lumière, qui est disposé au-dessous de l'unité de réception pour fournir, à l'unité de réception, une source de lumière permettant de mettre en forme le produit en sortie, et qui durcit ainsi la résine photodurcissable; une plaque disposée au-dessus de l'unité de réception d'une manière verticalement mobile pour permettre à la résine photodurcissable en couches individuelles d'être empilée sur sa surface inférieure tout en étant plongée dans la résine photodurcissable, et qui forme ainsi un produit en sortie tridimensionnel; et un élément d'élévation incliné qui élève la plaque après l'achèvement de l'empilement d'une couche individuelle sur la plaque, de manière à permettre l'empilement de la couche individuelle suivante tout en séparant la plaque de la surface inférieure de l'unité de réception, et qui élève et abaisse la plaque tout en ajustant l'angle d'inclinaison de la plaque.
(KO) 광경화성 수지를 이용하여 레이어를 한 층씩 적층하면서 출력물을 조형할 수 있는 3D 프린터 및 3D 프린팅 방법을 제시하며, 광경화성 수지를 수용하는 수납부; 상기 수납부의 하부에 설치되어 출력물의 조형을 위한 광원을 상기 수납부로 제공하여 광경화성 수지를 경화시키는 광엔진; 상기 수납부의 상부에 승강가능하게 설치되어 광경화성 수지에 담기면서 저면에 광경화성 수지를 단층별로 적층하여 3차원 출력물을 형성하는 플레이트; 및 상기 플레이트에 하나의 단층의 적층이 완료된 후 상기 플레이트를 상승시켜 상기 수납부의 바닥면에서 분리하면서 다음 단층의 적층을 허용하되, 상기 플레이트의 경사각도를 조절하면서 상기 플레이트를 상승 및 하강시키는 경사승강부재를 포함한다.
