The Mirrored Evolution of Crosslinked Photopolymers for 3D Printing
By Aric Yackly, business development manager, Stratasys For those of us who are old enough to have driven in the 1980s, we remember (without our rose-colored glasses on) that the fresh plastic interiors of the cars we drove changed from tough, bright, glossy colors to brittle and sun-faded over a shorter period of time than we’d have hoped for. That is just a quick … [Read more...] about The Mirrored Evolution of Crosslinked Photopolymers for 3D Printing
The Development of a Low-Migration Photoinitiator
By Syunyua Horii, Chief, R&D Division, Osaka Organic Chemical Industry Ltd. Photocurable compositions containing photoinitiators and polymerizable monomeric components are widely used in additive manufacturing, paints, inks, adhesives, sealants, insulating films, protective coatings and films. Since 2005, when it was confirmed that certain components from UV-curable inks … [Read more...] about The Development of a Low-Migration Photoinitiator
