Selective Laser Melting (SLM)

For metal components with high density

Selective Laser Melting (SLM) or Laser Beam Melting (LBM) describe the selective melting of metal powders. This generative manufacturing process features excellent material properties which are equal to conventionally manufactured metal components in all aspects. For selective laser melting, metal powder is applied in layers and melted into a component with the laser. This processes generates components with a density of over 99 %.

Also known as: Laser Powder Bed Fusion (LPBF oder L-PBF), Direct Metal Laser Sintering (DMLS), Laser Metal Fusion (LMF), Direct Metal Printing (DMP)
