Document Type and Number:
WIPO Patent Application WO/2019/045162
Kind Code:
A1
Abstract:
The present invention relates to a 3D printing apparatus having a wiper-type powder supply part and, more specifically, to a 3D printing apparatus having a wiper-type powder supply part, in which a plurality of powder supply chambers and a plurality of shaping chambers are provided in a circumferential direction, and a hybrid powder supply part is configured to have a rotation diameter extending to the positions of the powder supply chambers and the shaping chambers, thus allowing the apparatus to be simplified and working time to be reduced. To this end, a 3D printing apparatus having a wiper-type powder supply part is provided, which is configured to comprise: a main body in which a plurality of powder supply chambers for supplying powder and a plurality of shaping chambers for 3D shaping are alternately arranged in the circumferential direction; a laser oscillation member which is installed above the main body and which performs 3D shaping by emitting laser while being moved toward the shaping chambers; and a hybrid powder supply part which is shaft-coupled to the center of the main body and rotates in a circumferential direction of the main body, wherein the hybrid powder supply part supplies the powder accommodated in the powder supply chambers to the neighboring shaping chambers and performs a planarization operation in succession.
