Selective Laser Melting. Selective Laser Melting (SLM) is an Additive Manufacturing technology that uses metal powder to create your parts. The metal 3D printer spreads a thin layer of the metal powder on the bed, then a laser melts the metal creating the shape of your 3D model. The next layer of powder is placed and the process repeats itself.
