Selective Laser Melting (SLM)
SLM (Selective Laser Melting) is in an additive manufacturing method specially developped for 3D Printing metal alloys. It creates parts additively by fusing metal powder particles together in a full melting process. Like in the SLS process, your metal part will be created layer by layer, according to your 3D model. Unlike DMLS, SLM fully melts the powder, and therefore it needs to reach a higher temperature than this other metal 3D printing technique. The build chamber is filled with an inert gas (either argon or nitrogen at oxygen levels below 500 parts per million) in order to create the perfect conditions for melting.
