Selective Laser Sintering

Hunting for parts produced in material you can actually use? SLS printing could be your answer. Selective Laser Sintering (SLS) is a layer-by-layer additive 3D printing process using powdered nylon. This material is fused in slices by a high-powered laser to form functional end-use parts. Better yet, printing in this way, for example if you perform nylon printing, will give you a powerful, malleable, and versatile end product.

Nylon is a flexible and strong production material so end-use parts tend to be parts with flex features, hinges, snaps, clips and/or are exposed to high or low temperatures or caustic chemicals. The SLS process is known for its ability to produce parts from polymer and nylon printing as well as laser sintering that allows you to control the degree of melting the material at hand.

Parts from SLS printing can be used for production.


  • Slightly longer lead times
  • Rougher surface finish
  • Lower tolerance / less precise build





“We just inspected some of the INVAR machined parts that recently arrived from our latest project with you and wanted to pass along how nicely they turned out. The dimensions were spot on and fit & finish looked great. The ultem (PEI) parts on this order also turned out great!” — an advanced laser and electro-optical solutions company
