Selective laser melting - Wikipedia

Selective laser melting (SLM), also known as direct metal laser sintering (DMLS) or laser powder bed fusion (LPBF), is a rapid prototyping, 3D printing, or additive manufacturing technique designed to use a high power-density laser to melt and fuse metallic powders together. To many SLM is considered to be a subcategory of selective laser sintering ().

Selective Laser Melting - an overview | ScienceDirect Topics

Selective Laser Melting (SLM) is a powder bed AM technology in which parts are fabricated layer by layer using the action of a high-energy beam on a powder bed. In this process, the powders are fully melted and solidified. The process is very similar to SLS process but the energy of the beam is much higher and the process is performed under controlled atmosphere.
