Advantages of PolyJet Technology
Advantages of parts built with a Stratasys PolyJet Machine
Realistic Parts
Stratasys PolyJet 3D Printers are based on proven technology, which creates precise prototypes that set the standard for finished-product realism.
Their fine resolution makes complex shapes, intricate details and smooth surfaces possible.
Precise Models
PolyJet 3D Printing works by jetting layers of liquid photopolymer onto a build tray and instantly curing them with UV light.
The fine layers build up to create a precise 3D model or prototype. Models are ready to handle right out of the 3D printer, with no post-curing needed.
Better ideas, easier sell
PolyJet 3D printed models improve communication and collaboration because they produce amazingly accurate representations of your ideas that you can share with your team and your clients for a faster, more confident buy-in.
