Visible to near-infrared light activated photopolymer resins
BackgroundResin 3D printing has many advantages, such as high precision, smooth surface finish, and rapid printing speed. Conventional LCD or DLP devices use ultraviolet (UV) light to activate photo-initiators in the resin. A cheaper, less power hungry, and more biocompatible alternative would be to use visible light to activate photo-sensitizers in...
