PBF of metal parts

The PBF technologies for metal products are still the only AM technologies capable of processing metal materials, which are of substantial importance for engineering applications. The most important technologies for processing of metal materials, which differ by the source of heating energy, are:

  • Direct Metal Laser Sintering (DMLS) technology, that is also called Selective Laser Melting (SLM) technology;
  • Electron Beam Melting (EBM) technology

PBF technologies for polymer materials have following characteristics:

  • While the powder in the powder bin is capable of supporting the products, the cooling of the product during production process requires support structures that serve as heat conductors from the hot top products layer to the cold baseplate.
  • High temperature gradients lead to strong residual stresses in products , and the hat treatment is a usual post-processing step for all metal PBF technologies;
