Selective Laser Sintering

PRODUCTION-GRADE NYLON PRINTING FOR BATCH PRODUCTION, FUNCTIONAL TESTING, RAPID PROTOTYPING, HIGH-HEAT AND CHEMICALLY RESISTANT APPLICATIONS

Functional, production-grade nylon parts

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.

How to Select the Right Manufacturing Solution

From rapid and functional prototyping, appearance models to low-volume production using both additive manufacturing and traditional subtractive processes; the choices to develop your project are almost endless.

About this process

Overview

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
