Beschreibung
Zusammenfassung:	The present invention relates to a three-dimensional (3D) printer and a driving method thereof, the 3D printer comprising: a driving module which divides a three-dimensional molding model into a plurality of unit layers, generates a cross-sectional image for each unit layer, detects the size of the cross-sectional image for each unit layer, and sets a moving distance and position for each unit layer, wherein the three-dimensional molding model is disposed close to a preset origin position in an output area; and a recoater module which discharges and applies a photocurable liquid resin onto the output area while moving according to the moving distance and position of each unit layer. 본 발명은 3차원 프린터 및 이의 구동 방법에 관한 것으로, 출력 영역의 미리 설정된 원점 위치에 근접하게 배치된 입체 성형 모델을 복수의 단위 층으로 구분하여 단위 층 별 단면 이미지를 생성하고, 단위 층 별 단면 이미지의 크기를 검출하여 단위 층 별 이동 거리 및 위치를 설정하는 구동 모듈, 및 단위 층 별 이동 거리 및 위치에 따라 이동하여 출력 영역 상에 광 경화성 액상 수지를 토출 및 도포하는 리코터 모듈을 포함한다.
