Centimeter-Scale Curing Depths in Laser-Assisted 3D Printing of Photopolymers Enabled by Er<sup>3+</sup> Upconversion and Green Light-Absorbing Photosensitizer
Photopolymer resins used in stereolithographic 3D printing are limited to penetration depths of less than 1 mm. Our approach explores the use of near-infrared (NIR) to visible upconversion (UC) emissions from lanthanide-based phosphors to initiate photopolymer crosslinking at a much higher depth. Th...
