SML is a particularly instant prototyping, 3D printing, or Additive Manufacturing (AM) technique designed to use a high power-density laser to melt and fuse metallic powders together.
The steps of the SLM process are the same as other laser-based additive technologies: first of all a roller will apply a layer of metal powder, then the laser will sinter the powder according to the 3D file, and the build platform will get down before applying a new layer of powder... The process will be repeated until the desired part is created. Once it's finished, the metal part needs to cool down before being extracted.
Selective Laser Melting process uses supports in order to reinforce small angles and hangovers of the parts but also to stick the design to the job tray. The support will be removed manually after cooling. Various finishing techniques such as milling, thermal treatment or touring are commonly used after the print in order to achieve the functionnal requirements of the part.
- The SLM process is highly beneficial for those who need to produce their metal parts for prototyping or production rapidly.
- With SLM, it's also possible to get thin-walled objects and intricate geometries in order to create lightweight designs.
- SLM as other metal 3D printing technologies is appropriate for manufacturing small batches. In this case, our metal 3D printing team will do a complete study of your project and your requirements.
