White Paper: Injection Molding from 3D Printed Molds

We discuss:

  • The steps and results of our test with Galomb
  • Recommendations and best practices for injection molding with 3D printed molds
  • Suggestions for designing and 3D printing molds


This white paper describes the production of small injection molded thermoplastic parts that were created with 3D-printed molds produced on a Form 2 printer and injected using a Galomb Model-B100 Injection Molder. Two mold designs were tested in Clear Resin: one of a large butterfly and one that produces four smaller butterflies in one shot. A third mold of a USB device enclosure was tested in High Temp resin. These molds were 3D printed by Formlabs and the injection molded parts were produced by Galomb Inc and Formlabs in a variety of materials.
