Oxygen-tolerant photopolymer resins
BackgroundLight-driven polymerization methods for 3D printing are particularly attractive due to unparalleled speed and resolution, yet the reliance on high energy UV/​violet light in contemporary processes limits the number of compatible materials due to pervasive absorption, scattering, and degradation at these short wavelengths. Such issues can be...

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...
