COR Alpha Photopolymer Resin for 385nm DLP 3D Printers

COR Alpha is the most rugged photopolymer resin on the market. What do we mean by rugged? 

• Unparalleled impact resistance (un-notched IZOD >800 J/m)
• Very high working temperature (glass transition >150 °C)
• Best-in-class ductility (> 20% elongation at break)
• Extreme chemical resistance, including 10-100x lower moisture absorption than typical photopolymer resins
• Grade 0 Cytotoxicity (ISO 10993-5)

Important Notice: COR Alpha photopolymer resin is intended for use by trained additive manufacturing professionals working in industrial, manufacturing, and laboratory facilities. At this time, we discourage printing with COR in home or office environments. We reserve the right to cancel your resin purchase if you cannot meet the safety requirements. If you do not have access to this type of facility or training, we would be happy to print COR parts for you at https://polyspectra.com/start-here !
