Selective Laser Melting (SLM) or Direct Metal Laser Sintering (DMLS) or Laser Powder Bed Fusion (LPBF) is an additive manufacturing process that use a high-powered laser to selectively melt metal powder in a powder bed to create 3D metal parts. The process involves layer-by-layer melting of the powder to create complex geometries with high accuracy and precision. The laser is controlled by a computer-aided design (CAD) model to selectively melt the powder in the desired areas, which then solidifies to form a solid metal part.
