SLM is an exciting technology with numerous potential applications. As use cases grow, technology matures, and processes and materials become cheaper, we should see it become more commonplace, it is widely used in many fields.
1- Undertake the next layer of unformed powder layer, prevent the laser scanning of too thick metal powder layer and collapse;
2- After the powder is heated, melted and cooled during molding process, there is shrinkage stress inside, which may cause the parts to warp, etc. The support structure connects the formed part and the unformed part, which can effectively suppress this shrinkage and keep the stress balance of the formed part. After completion, support on the model will be removed, and the surface is ground and polished with a sander. Then the model is completed.
Under the control of the computer, the laser will be irradiated to the designated area, the metal powder will be melted, and the molten metal will rapidly cool and solidify. when finishing one layer, the forming substrate will lower by a layer thickness, and then a new layer of powder is applied by the scraper. The above process will be repeated until the workpiece is formed.

SLM process is mainly divided into heat treatment, wire cutting metal printing, polishing , grinding, sandblasting and so on.
Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS) are two metal additive manufacturing processes belonging to the powder bed fusion 3D printing family. The materials used in the process are all granular metals.
