• Produce Highly Durable and Complex Geometries in Production-Grade Nylon

    SLS methods are ideal for durable, functional parts for low to mid-volume production, rapid prototyping and functional testing. A range of material options are available, including industrial-grade, tough, impact and fatigue-resistant nylon 11 materials or strong, food-grade, biocompatible, or flame-retardant capable nylon 12 thermoplastics, and filled nylons for advanced properties in terms of stiffness, temperature resistance, strength and surface finish.

About this Process


SLS uses a high-powered C02 laser to fuse small particles of powdered material to create 3 dimensional parts. The laser selectively fuses powdered material by scanning X&Y cross-sections on the surface of a powder bed. The model is built one layer at a time from supplied 3D CAD data. 

SLS produces parts from impact-resistant engineering plastic, great for low-to mid-volume end-use parts, enclosures, snap-fit parts, automotive components and thin-walled ducting.

SLS produces complex geometries, for low-volume parts that would typically require assembly using traditional manufacturing methods.

Tolerances for standard resolution:

  • X/Y planes: +/-.005” for the first inch, plus +/-.005” for every inch thereafter
  • Z plane: +/-.010” for the first inch, plus +/-.005” for every inch thereafter
