How COR Works

Printing Rugged Resin in 3 Steps

Cyclic Olefin Resin (COR) photopolymers feature best-in-class thermomechanical performance, chemical resistance, long-term durability, and impact strength.
You choose the printer, we’ll help you make it real.

Step 1: Print

COR photopolymers are compatible with a wide array of industrial and desktop DLP & LCD resin 3D printers. You choose the printer that meets your requirements. COR will dramatically increase your ROI.

Step 2: Rinse

Compared to most photopolymers, COR is incredibly easy to clean, due to its extremely low viscosity. polySpectra’s supaRinse cleaning fluid is a safe and reliable solution for washing away uncured COR.

Step 3: Bake

Cyclic Olefin Resins have incredibly high working temperatures, requiring a thermal post-cure. polySpectra waveCure is a proprietary heat transfer fluid that can fully cure COR parts in a consumer microwave, in just a few minutes!
