Digital Photopolymer

Digital photopolymer is a PolyJet material that can be printed in multiple hardnesses and colors.

Parts made with two types of digital photopolymer

Product Description

Protolabs’ PolyJet process builds parts comprised of digital photopolymer. The material is available in multiple Shore A hardnesses and colors: clear/translucent, white, and black. It supports complex geometries and can take on a range of mechanical properties.


Digital photopolymer can be leveraged in a variety of 3D printing applications
that incorporate flexible features. It’s routinely used to prototype overmolded
and liquid silicone rubber parts such as: gaskets, seals, covers, and straps.

Key Product Benefits

  • Two-toned coloring aesthetics
  • Soft touch and flexible features
  • Improved grip and impact resistance
