photopolymer resin is a type of polymer that changes its physical properties when introduced to light and its VOC free resin.

In the case of 3D printing, these are typically liquid plastic resins that harden when exposed to a light source, such as a laser, a lamp, a projector or light-emitting diodes (LEDs) and most of these light sources irradiate ultraviolet (UV) light, which works perfectly with photocuring resin.
