Most photopolymers suffer from very low working temperatures, they will deform when heated.

COR Alpha takes the heat like a pro.

Rugged under pressure.

Want to build something real? So do we.

COR Alpha is tough enough to take a beating. Watch our part crushed under almost 4 tons:

Stands up to solvents.

Need parts that won't submit to harsh solvents like acetone?

Rest assured that COR Alpha will stay strong.

The core is COR.

COR stands for Cyclic Olefin Resin, a new family of engineering-grade materials for additive manufacturing developed by polySpectra.
