Photopolymer, also known as resin, is a light-sensitive liquid plastic that is widely used in stereolithography (SLA) and digital light processing (DLP) 3D printing technologies. When exposed to UV light, photopolymer solidifies and becomes polymerized, allowing objects to be built one ultra-thin layer at a time. This innovative material enables high-resolution and detailed 3D printed... https://articlescad.com/what-is-photopolymer-understanding-the-basics-of-this-versatile-light-sensitive-material-62809.html
