Who we are

Spectra Photopolymers, headquartered in Millbury, Ohio, develops and manufactures a variety of products such as 3D Printing resins, adhesives, coatings, photoinitiators, and color change labels and concentrates. Our goal is to provide solutions for new technologies and applications in the radiation curing field.

Spectra Photopolymers (formerly Spectra Group Ltd.) started in 1990 as a small startup to print 3D medical models from CT and MRI scans. Since then, the company has grown to serve many sectors of the radiation curing industry and become a leader in the custom development and manufacture of 3D printing resins, UV curable coatings and adhesives, and other UV technology products.

In 2017, Spectra Photopolymers became part of the Formlabs family as a wholly owned subsidiary that manufactures all of Formlabs’ Resins.
