Digital Light Processing (DLP) is a type of vat polymerization. Vat polymerization 3D printing technologies make use of a (liquid) photopolymer resin which is able to cure (solidify) under a light source.
In the world of vat polymerization, there are two main technologies: SLA and DLP. Naturally, both use resin and a light source to produce parts, the main difference being the type of light source which is used to cure the resin. SLA printers use lasers combined with galvanometers to cure resin, while DLP 3D printer, the light source is a specially developed digital light projector screen.
