摘要

An embodiment of the present invention relates to a powder supplying device for a 3D printer, which comprises: a powder storage unit which is installed on the outside of a chamber unit in which shape machining is performed, and receives and stores powder; a powder supplying unit which is installed on the inside of the chamber unit to be movable, and supplies the powder moved from the powder storage unit after allowing the same to fall to a powder insertion unit on the inside of the chamber unit; a powder transport unit which connects the powder storage unit to the powder supplying unit, and can open and close a connecting path, thereby allowing the powder to be moved or blocking the movement thereof; and a driving unit which allows movement such that the powder supplying unit may be located at the upper portion of the powder insertion unit on the inside of the chamber unit. Therefore, a quick operation can be enabled, and a high-quality product can be obtained.;COPYRIGHT KIPO 2020
