PolyJet & 3D Printed Silicone (60-65%)

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 hardness's (durometers) are available, which work well for components with elastomeric features like gaskets, seals, and housings. 

PolyJet design guidelines will help you understand capabilities and limitations.


Why Choose PolyJet For Your 3D Printing Project?

PolyJet technology offers outstanding detail, surface smoothness and precision, creating  detailed prototypes that convey final-product aesthetics. You can simulate elastomers and flexible parts, create prototyping designs for overmoulding and liquid silicone rubber moulding and manufacture really complex part geometries. We also offer a number of secondary services such as painting, post machining and measurement and inspection, to further enhance the finish of your 3D-printed project design.

How Does PolyJet 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.
