3D Print

Stereolithography (SLA) or resin 3D printing: This style of printing involves curing photopolymer resin with UV light to create solid objects. The technology first appeared as SLA, which uses a laser as the UV light source. Being the pioneering printing process, the term “SLA” has been used eponymously for all of resin printing, but there have been more recent variations of the technology as well. These use projectors (with digital light projection, or DLP) and UV-backlit LCD screens (LCD masking) to supply the UV light.
