Material Jetting (PolyJet / MJP) · Photopolymers · Flexible
Rubber-like photopolymer
Soft zones printed together with rigid parts; keypads, grips and gasket prototypes.
What is Rubber-like photopolymer?
Rubber-like PolyJet materials can be printed in hardnesses from 30A to 95A and combined with rigid photopolymer in the same part. They are excellent for prototypes of overmolded products.
