SLS Selective Laser Sintering Material Selection Guide

Material Description Advantages Considerations Applications
DuraForm Polyamide (PA)

Used to build durable, functional models, this white nylon-like material provides an accurate part with good detail.

  • Durable, higher strength than SLA
  • Requires less post-processing than SLA
  • Can be primed and painted
  • Can be machined
  • Less detail than SLA
  • Slightly less accurate than SLA
  • Tolerances +/- 0.010 (Dependant upon part geometry)
  • Concept models
  • Fit and function
  • Excellent for show display models that receive excessive handling
DuraForm Glass-filled (GF) Used to produce rugged, engineering thermoplastic parts that withstand aggressive functional testing
  • Increased stiffness, heat resistance and mechanical integrity (relative to PA)
  • Perfect material for extreme testing
 
  • Durable parts without tooling
  • Heat and chemical resistant
  • Excellent surface finish
DuraForm Aluminum-filled (AF) Plastic An engineered composite with the durability of an injection molded part and the appearance of cast aluminum
  • Offers toughness of injection-molded ABS and polypropylene
  • Produce durable end-use parts without tooling
  • Create accurate and repeatable parts as demanded by manufactures.
 
  • Functional pro types or end-use parts that require high stiffness and/or heat resistance
  • Accurate, durable master patterns
  • Parts that require the look and feel of cast aluminum
