PolyJet Molds for Silicone Parts

Liquid silicone rubber (LSR) is very versatile and has very unique properties, which makes it a frequently used material for molds. It is non-reactive, stable and resistant to extreme environments and temperatures.

Making LSR parts with RTV molds is a multistage process requiring time and labor to make the patterns and molds. With PolyJet technology, you can create LSR molds more efficiently and at a lower cost. In this guide, you’ll learn how to create molds using PolyJet technology for your silicone parts. The main takeaways will be:

  • Understanding the overall process of printing molds for silicone parts
  • Designing a tool for molding using CAD software 
  • Preparing your files for importing into a PolyJet 3D printer
  • Choosing the right material
  • And more!

Once you read through this guide, you will have the necessary steps to start 3D printing your molds in-house.
