Silicone Polyjet Printing


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, 3D Printed silicone is ideal for hoses and gaskets. Functional prototypes can be produced for initial product validation tests. The printed parts have characteristics of silicone such as resistance, reproducibility after deformation or stress, elasticity.

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.
