Now offered as part of Proto Labs' (Maple Plain, MN) industrial 3D printing services, PolyJet technology provides product designers and engineers with the ability to manufacture elastomeric and overmolded prototypes without investing in tooling. Product developers can leverage PolyJet to create 3D-printed parts comprised of both elastomeric and rigid materials as well as multiple colors. Its material selection includes multiple Shore A hardnesses of tear-resistant Agilus 30 for increased durability. PolyJet parts exhibit smooth surface finishes and can support complex geometries with flexible features. Like other 3D printing processes, PolyJet builds parts layer-by-layer. The machine jets out droplets of liquid photopolymers onto the build platform where they are immediately UV cured. Once the build is complete, support structures are removed, and the parts are ready without the need for additional finishing. Proto Labs’ proprietary software and digital approach to manufacturing allows customers to upload a 3D CAD file of their design at protolabs.com, receive an instant quote, and have 3D-printed parts in hand within days.
