Selective Laser Sintering(SLS)

Release time:2018-09-05


Through Selective Laser Sintering (SLS), rapid prototypes are produced from production materials. The parts typically have the highest strength. A CO2 laser sinters powdered material layer by layer to create a durable, solid object. The prototype can be used for functional testing in almost all applications including functional prototypes, electronic packaging, high-temperature components, snap fits, and living hinges because they are constructed from real engineering materials.

When durability and/or high heat tolerance are required, SLS can produce parts which closely represent the physical properties of the production material.

  • Patented in 1989.
  • Considerably stronger than SLA; sometimes structurally-functional parts are possible.
  • Laser beam selectively fuses powdered materials: Nylon, elastomers, and soon metal.
  • Advantage over SLA: The variety of materials, and the ability to approximate common engineering plastics.
  • No milling step, so accuracy in z can suffer.
  • Process is simple: No milling or masking steps are required.
  • Living hinges are possible with the thermoplastic-like materials.
  • The surface will be powdery and porous unless sealant is used. Sealant also strengthens the part.
  • Uncured material is easily removed after a build by brushing or blowing it off.


  • Limited number of prototypes needed (1-10).
  • Form and fit testing
  • Functional testing
  • Field testing
