Technology No. 7: SLM
What it is: Selective laser melting
Inventors: Dr. Dieter Schwarze and Dr. Matthias Fockele of F&S Stereolithographietechnik GmbH; and ILT researchers Dr. Wilhelm Meiners and Dr. Konrad Wissenbach
Materials: Stainless steel, tool steel, cobalt chrome, titanium, aluminum in atomized form
Process: A high-powered fiber laser beam fuses fine metallic powders together to create three-dimensional metal parts. Although known as laser sintering, this SLM process actually fully melts the metal into a solid homogeneous mass, which is more similar to Electron Beam Melting (EBM), which uses an electron beam as the energy source. Trade names include DMLS and LaserCusing.
