Problems solved by technology

[0003] Metal SLM printing technology is a metal 3D printing technology, which is mostly used for forming complex structures of difficult-to-machine alloys. It can manufacture metal parts with built-in complex structures, such as aviation blades with built-in flow channels. Layers are accumulated and formed, and the surface roughness of the parts obtained by sintering is poor. For parts with roughness requirements for built-in structures, simple SLM additive manufacturing is difficult to meet the demand

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a metal SLM printing and laser polishing integrated machine. Background technique [0002] 3D printer, also known as three-dimensional printer (3DP), is a machine based on cumulative manufacturing technology, that is, rapid prototyping technology. It is based on digital model files. After putting data and raw materials into the 3D printer, the 3D printer will use special wax materials , Powdered metal or plastic and other bondable materials, according to the program to create three-dimensional objects by printing layers of bonded materials. The biggest difference between a 3D printer and a traditional printer is that the "ink" it uses is a real raw material. There are various forms of stacking thin layers, and there are various types of media that can be used for printing, from a variety of plastics to metals, ceramics and rubber. class of substances. [0003] Metal SLM pri...
