Frequently Asked Questions

What is required to print with COR photopolymer resins?

Cyclic Olefin Resin (COR) is a family of industrial photopolymer resins developed for DLP 3D printers.

polySpectra currently supports validated printers from Asiga, Stratasys (Origin), and Desktop Metal (ETEC) - the full list can be found on the requirements page.

We recommend that the printer and part-cleaning work areas are well ventilated, within a manufacturing or laboratory environment. At this time, we discourage at-home or in-office printing of COR photopolymer products.

COR Alpha and COR Black require a thermal post-cure. Review our validated and exploratory post-curing options here.

For long-term storage, we recommend cold storage. Read more about storage.

What is the difference between validated workflows and exploratory options?

polySpectra fully supports and guarantees the printability and material performance of our validated workflows.

At the same time, we do not want to limit the creativity of our customers to explore additional workflows that may be more suited to their needs and applications. To encourage our customers and partners to innovate, we additionally share exploratory options. However, we cannot guarantee the same performance criteria, or offer in-depth troubleshooting or customer support for our exploratory options.

How much does COR Alpha cost?

Introductory pricing for COR Alpha is $600/kg, and can be purchased directly here. For bulk pricing or to learn more about our partnerships, please contact partners [at] polyspectra [dot] com.

Is COR Alpha FDA-approved?

For most medical devices, the FDA certifies the device, not the material. COR Alpha can be used to 3D print medical-grade products.

COR Alpha features Grade-0 cytotoxicity (10993-5), a very high working temperature (Tg >150 °C) and incredibly low moisture absorption, which make it a highly bio-inert material.
