SLA

Stereolithography, or SLA for short, is one of the most commonly used 3D printing technologies used today. The process builds 3D parts from a photopolymer liquid resin which is hardened by a UV laser. The laser traces out the profile of each slice of the part and gradually builds a part layer by layer. After the laser has completed a slice, the build table lowers into the resin and the process starts all over again for the next layer.
