Title
(EN) 3D PRINTING SYSTEM
(FR) SYSTÈME D'IMPRESSION 3D
(KO) 3D 프린팅 시스템
Abstract
(EN) Provided is a 3D printing system capable of forming an object to be printed while laminating layers one upon another by using photocurable resin, the 3D printing system comprising: a receiving part for receiving photocurable resin; a light engine which is installed at the lower side of the receiving part and provides a light source for forming an object to be printed to the receiving part to cure the photocurable resin; a plate which is installed at the upper side of the receiving part to be able to move up and down, and forms a three-dimensional object to be printed by laminating photocurable resin for each monolayer on the bottom surface thereof while being immersed in the photocurable resin; an elevation member which, after lamination of a monolayer on the plate is completed, moves the plate up to separate the plate from the bottom surface of the receiving part, and moves the plate down again to allow lamination of a subsequent monolayer; and a resin supply member for supplying photocurable resin to the receiving part up to a predetermined level, the resin supply member selectively supplying the photocurable resin to a region, in which printing is performed by the light engine, among the reception space of the receiving part while adjusting a position of supply of the photocurable resin.
(FR) Il est fourni un système d'impression 3D capable de former un objet à imprimer tout en stratifiant des couches les unes sur les autres en utilisant une résine photodurcissable, le système d'impression 3D comprenant : une partie de réception pour recevoir une résine photodurcissable ; un moteur de lumière qui est installé au niveau du côté inférieur de la partie de réception et fournit une source de lumière pour former un objet à imprimer sur la partie de réception pour durcir la résine photodurcissable ; une plaque qui est installée au niveau du côté supérieur de la partie de réception pour pouvoir se déplacer vers le haut et vers le bas, et forme un objet tridimensionnel à imprimer par stratification d'une résine photodurcissable pour chaque monocouche sur sa surface de fond tout en étant immergée dans la résine photodurcissable ; un élément d'élévation qui, après qu'une stratification d'une monocouche sur la plaque est achevée, déplace la plaque vers le haut pour séparer la plaque de la surface de fond de la partie de réception, et déplace à nouveau la plaque vers le bas pour permettre une stratification d'une monocouche ultérieure ; et un élément d'alimentation en résine pour alimenter une résine photodurcissable dans la partie de réception jusqu'à un niveau prédéterminé, l'élément d'alimentation en résine alimentant sélectivement la résine photodurcissable dans une région, dans laquelle une impression est effectuée par le moteur de lumière, parmi l'espace de réception de la partie de réception tout en ajustant une position d'alimentation de la résine photodurcissable.
(KO) 광경화성 수지를 이용하여 레이어를 한 층씩 적층하면서 출력물을 조형할 수 있는 3D 프린팅 시스템을 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; 상기 플레이트에 하나의 단층의 적층이 완료된 후 상기 플레이트를 상승시켜 상기 수납부의 바닥면에서 분리하고, 다시 플레이트를 하강시켜 다음 단층의 적층을 허용하는 승강부재; 및 상기 수납부에 광경화성 수지를 소정의 수위로 공급하되, 광경화성 수지의 공급위치를 조절하면서 상기 수납부의 수용공간 중 상기 광엔진에 의해 프린팅이 이루어지는 영역에 광경화성 수지를 선택적으로 공급하는 레진공급부재를 포함한다.
