Polypropylene is one of your go-to plastics for injection molding, and being both flexible and tough, you can do sexy things like making living hinges out of the stuff. But you are of course limited to what you can produce in a mold.
Stratasys is hoping to remove this barrier with Endur, a simulated polypropylene material that can be 3D-printed in their PolyJet machines.
Just like the name implies, Endur is tough. The polypropylene-like material offers both high impact resistance and superior elongation at break. Endur has a heat-deflection temperature up to 129°F/ 54°C, excellent dimensional stability and comes in a bright white color. It also features an excellent surface finish to make it easier to achieve a smooth look and feel.
These properties make Endur attractive for 3D printing prototypes that need the flexibility, appearance and toughness of polypropylene for a wide range of form, fit and assembly applications. This includes moving parts, snap-fit components, and small cases and containers with lids. The white tone and smooth surface finish make it ideal for consumer goods, electronics and household appliances, lab equipment and automotive parts.
