What is Vat Photo Polymerization?

SLA (Stereolithography) is part of vat photo polymerization AM method where ultra violet (UV) laser is used to cure photopolymer liquid resin and turn into hard plastic parts. A photopolymer or light-activated resin is a polymer that changes its properties when exposed to light, often in the ultraviolet or visible region of the electromagnetic spectrum by causing its molecules chains to link
