polySpectra has launched its flagship material in a new formulation compatible with desktop DLP and LCD resin 3D printers. Previously available solely for use on 385nm wavelength 3D printers, limiting use to industrial hardware, the new formulation expands availability to 405nm wavelength systems.

“We are very excited to announce the 405nm version of COR Alpha – which now gives engineers the ability to access the world’s most rugged photopolymers on a wide array of resin 3D printers spanning every price point,” said Raymond Weitekamp, PhD, polySpectra Founder and CEO.

While many “production-grade” resins available today for 3D printing can create high-resolution parts with unique geometric complexity, they are often too brittle for demanding real-world applications. This inherently limits their use to prototyping and other less-demanding use cases.

polySpectra launches 405nm-compatible resin for desktop 3D printers.

COR stands for “Cyclic Olefin Resin,” a new family of engineering-grade materials for additive manufacturing. COR Alpha relies on Nobel-winning chemistry to offer durability, high impact strength, high-temperature performance, and moisture- and chemical-resistant capabilities – all without brittleness.

Satellite components, consumer products, electronic connectors, and highly durable tooling for injection molding are some of the high-value application examples where COR Alpha can tip the scale from prototyping to production.

COR Alpha has been commercially available since 2022 in a 385nm wavelength, compatible with and validated on a catalog of industrial-grade 3D printers. The new COR Alpha resin 405nm formulation expands the list of compatible 3D printers.

According to the company, inexpensive desktop 3D printers will now also have the capability to print with rugged resin. R&D labs, small businesses without industrial budgets, and other users – many who already own desktop 3D printers – now gain the ability to create end-use parts in-house.
