Selective Laser Sintering (SLS)

For cost-efficient and functional components

Selective Laser Sintering (SLS) is similar to Selective Laser Melting (SLM). A thin layer of powder (polymer) is applied to the base plate and melted with a heat source (laser). Then the base plate is lowered while the next powder layer is applied and the melting is repeated, so that components are generated layer by layer using selective melting. This results in components with properties similar to those manufactured with injection molding.
