Prototyping Material
Rigur and Durus materials are advanced simulated polypropylene, offering durability and a smooth finish.
TriMech can 3D print precision prototypes that look and behave like polypropylene. Rapidly create models to test form, fit and function for snap-fit assemblies, living hinges and durable housings and packaging.
Rigur (RGD450) is an advanced simulated polypropylene material that enables the ability to 3D print precision prototypes. Rigur offers durability and beautiful surface finish.
Durus (RGD430) is the original simulated polypropylene material and exhibits great impact resilience and an elongation at break of 44%.

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.
