Abstract

The invention discloses a powder spreading device for a 3D printer. The method of the invention includes: the powder dropping module is installed on one side of the linear motion module, and includes a powder spreading bin, a powder spreading roller, a switch control board, a cam control shaft, and an isolation baffle; the powder spreading bin is provided with a vertical plate, and the lower end of the vertical plate is provided with a vertical plate. It is separated from the bottom of the powder spreading bin; the powder spreading roller is placed between the lower end of the vertical plate and the bottom of the powder spreading bin, and together with the vertical plate, the powder spreading bin is divided into a powder storage bin and a powder dropping bin. In the powder spreading bin, the powder can be transported from the powder storage bin to the powder dropping bin by rotating itself; the switch control board is movably installed in the powder dropping bin, and there is a boss; the cam control shaft is provided with a cam, which is tangent to the boss, and the cam Both ends of the control shaft are movably installed in the powder drop bin; the isolation baffle is placed in the powder storage bin to divide the powder storage bin into an empty bin and a powder bin. The invention can carry out reasonable powder injection according to the amount of parts, reduce the workload of cleaning the powder, improve the iterative speed of product research and development, and improve the research and development efficiency.

Description

technical field

[0001] The invention belongs to the technical field of 3D printing, and particularly relates to a powder spreading device for a 3D printer. Background technique

[0002] Laser melting technology, also known as 3D printing technology, or SLM for short, is the most widely used one in additive manufacturing technology. SLM technology is a technology that uses a high-energy laser beam to rapidly melt micron-sized metal powder and rapidly solidify and form. Parts formed by SLM technology generally do not require subsequent processing or simple surface processing, and the mechanical properties of the parts are high, and the density is nearly 100%.

[0003] Selective laser melting technology has a relatively short development time, and there are fewer companies worldwide that have developed this technology and manufactured equipment to apply it, and fewer companies have developed its raw material (micron-scale metal powder), resulting in the application of this tec...
