본 발명은 파우더 베드 방식의 3D 프린터에서 파우더를 고르게 도포하는 기능을 수행하는 리코팅 장치와 이를 포함하는 3D 프린터에 관한 것으로서, 본 발명의 리코팅 장치는 리코팅 장치의 진행방향에 대해 수직인 방향으로 파우더의 흐름을 생성하는 평탄화 블레이드를 포함하여 형성되어, 리코팅 장치 전면에서 위치에 따라 파우더의 토출량이 불균일하게 토출되더라도, 이를 균일하게 평탄화할 수 있다. The present invention relates to a recoating device which performs the function of uniformly applying powder in a powder bed-type 3D printer, and a 3D printer including the recoating device. A recoating device of the present invention includes a flattening blade for generating a flow of powder in the direction perpendicular to the direction in which the recoating device progresses, and thus can uniformly flatten powder even if, depending on the position, a non-uniform amount of powder is discharged from the front of the recoating device.
