Abstract

The invention discloses a powder delivery mechanism for a 3D (three dimensional) printer. The 3D printer comprises a printer body, wherein a sealed cavity is formed in the printer body, a feed box is arranged in the sealed cavity, and the powder delivery mechanism is arranged on the feed box and comprises a powder delivery member arranged on the feed box, a motor arranged on the external wall of the sealed cavity and a transmission mechanism connecting the powder delivery member and the motor. The powder delivery mechanism is simple in structure and convenient to mount, meanwhile, the accuracy of mounting is guaranteed, the quantity of parts is reduced, and wiring is avoided.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a powder feeding mechanism for a 3D printer. Background technique [0002] 3D printing, also known as rapid prototyping and additive manufacturing, is a technology based on 3D data model files, using materials such as photosensitive resin, powdered plastic or metal, to construct objects by layer-by-layer printing. Before the 3D data model is output to the 3D printer, the 3D model needs to be layered and cut into hundreds or thousands of thin layers. A data file describing these thin layers is then output to a printer, which 3D prints layer by layer until the entire shape is superimposed. [0003] It has been widely used in product prototype manufacturing, performance testing and design inspection and verification in the fields of molds, automobiles, home appliances, medical, dental, jewelry, jewelry, etc., which greatly improves the speed of new product developmen...
