The present invention relates to a 3D printer output method, which comprises: an area setting step of setting an output area in which an output is formed and a non-output area in which no output is formed, among the areas on a build plate; a first supply step in which a liquid material is supplied to the non-output area; a flattening step in which the liquid material supplied in the first supply step is flattened by the movement of a recoating blade; a hardening step in which the liquid material flattened by irradiation of light is hardened; and a second supply step in which the liquid material is supplied to a portion hardened in the hardening step. The output area includes a first output area extending along the inner perimeter of the output area and having a predetermined width and a second output area surrounded by the first output area. The present invention can form accurate printouts using the liquid material. 본 발명은 3D 프린터의 출력 방법에 관한 것으로서, 빌드플레이트상의 영역 중 출력물이 형성되는 출력영역 및 출력물이 형성되지 않는 비출력영역을 설정하는 영역설정단계, 액상소재가 비출력영역에 공급되는 제1공급단계, 제1공급단계에서 공급된 액상소재가 리코팅블레이드의 이동에 의해 평탄화되는 평탄화단계, 광의 조사에 의해 평탄화된 액상소재가 경화되는 경화단계 및 액상소재가 경화단계에서 경화된 부분에 공급되는 제2공급단계를 포함하며, 출력영역은 출력영역 내측 둘레를 따라 연장되며 소정의 폭을 가지는 제1출력영역 및 제1출력영역에 둘러싸인 제2출력영역을 포함하는 것을 특징으로 하는 3D프린터의 출력방법을 제공한다.
