A photopolymer is a light-sensitive material that changes its properties when exposed to light. This change can be used to create a three-dimensional object by selectively hardening areas of a photopolymer using a light source.
Some of the emerging trends in photopolymers include the use of photopolymers for 3D printing, the use of photopolymers for solar cells, and the use of photopolymers for light-emitting diodes (LEDs).
