Abstract

The invention relates to a 3D printer and a powder spreading mechanism therefor. The powder spreading mechanism for the 3D printer comprises a square steel frame, a powder discharge assembly and a powder spreading assembly; the powder discharge assembly comprises a vibration plate, a guide plate structure, a vibration motor and a vibration cam; the top of the vibration plate is fixed to the squaresteel frame; a flexible vibration plate portion is formed at the lower portion of the vibration plate; the guide plate structure is obliquely arranged relative to the vibration plate; a powder outletspace is formed between the vibration plate and the guide plate structure; and the vibration motor is mounted at the bottom of the square steel frame through a connecting frame. The powder spreadingmechanism for the 3D printer is better in powder spreading effect.

Description

technical field [0001] The invention relates to a 3D printer and a powder spreading mechanism thereof. Background technique [0002] DP printing technology has gradually occupied a place in the foundry field. 3D printers are mainly based on additive manufacturing, and parts are constructed by layered printing, sintering, melting or bonding of powder solids of different materials. 3D printers generally include a powder spreading mechanism. However, the powder spreading mechanism is generally an integrated structure of the powder outlet assembly and the powder scraping assembly, which will cause movement of the powder scraping assembly when adjusting the amount of powder, which will affect the powder spreading effect. Contents of the invention [0003] Based on this, it is necessary to provide a 3D printer with a better powder spreading effect and a powder spreading mechanism thereof. [0004] A powder spreading mechanism of a 3D printer, comprising a square steel frame, a...
