Back to top Additive manufacturing of metal parts is set to revolutionize how many things are made. Selective laser melting (SLM) is one of the premier technologies, but how does it work? That’s what this article is all about. Metal orb with a complex shape, produced via SLM technology. Source: Phoenixdeventures Selective laser melting, or SLM, is a type of metal additive manufacturing or 3D printing. It is also known as powder bed fusion or direct metal laser sintering (DMLS). It uses a high power laser to fuse metal powders together. SLM is one of the most exciting 3D printing technologies available today and is utilized both for rapid prototyping and mass production. The range of metal alloys available is fairly extensive. The end result has properties equivalent to those manufactured via traditional manufacturing processes.
