PolyJet 3D Printing

PolyJet is an industrial 3D printing process that builds multi-material prototypes with flexible features and complex parts with intricate geometries in as fast as 1 day. A range of hardnesses (durometers) are available, which work well for components with elastomeric features like gaskets, seals, and housings.

How Does PolyJet 3D Printing Work?

The PolyJet process begins by spraying small droplets of liquid photopolymers in layers that are instantly UV cured. Voxels (three-dimensional pixels) are strategically placed during the build, which allow for the combination of both flexible and rigid photopolymers know as digital materials. Each voxel has a vertical thickness equal to the layer thickness of 30 microns. The fine layers of digital materials accumulate on the build platform to create accurate 3D-printed parts.

Each PolyJet part is completely coated in support material during the build, which ultimately is removed by hand using a pressurized water stream and a chemical solution bath. No post-curing is required after the manufacturing process.

PolyJet Material Options

PolyJet provides the ability to choose a desired hardness or combine material properties into a single build, which makes it ideal for prototyping overmolding parts. Shore A hardnesses of 30A, 40A, 50A, 60A, 70A, 85A, 95A, and rigid are available in these colors:

  • Digital Clear/Translucent
  • Digital Black
  • Digital White
