Polygon Pattern

Choosing the Right Material
for Injection Molds

An evaluation of various
3D printing techniques

Pump manufacturer Grundfos evaluated two PolyJet and two SLS materials to determine the best fit for 3D printing injection molds.

Material selection is a critical success factor when 3D printing injection molds. Realizing their own need for fast, production-ready injection mold prototypes, pump manufacturer Grundfos tested several 3D printing methods and materials to produce a variety of parts.

This white paper details their findings as they set out to:

  • Discover which materials yield the most intact parts
  • Create a complex injection molded part with threads
    and ribs
  • Achieve quicker turnaround from design to finish
