Stereolithography (SLA)
Stereolithography is the most widely used RP-technology. It can produce highly accurate and detailed polymer parts. SLA was the first RP-process, introduced in 1988 by 3-D Systems Inc. SLA uses a low-power, highly focused UV laser to produce a three dimensional object in a vat of liquid photosensitive polymer.
Stereolithography builds plastic parts or objects a layer at a time by tracing a laser beam on the surface of a vat of liquid photopolymer. This class of materials, originally developed for the printing and packaging industries, quickly solidifies wherever the laser beam strikes the surface of the liquid. Once one layer is completely traced, it's lowered a small distance into the vat and a second layer is traced right on top of the first. The self-adhesive property of the material causes the layers to bond to one another and eventually form a complete, three-dimensional object after many such layers are formed.
Abbreviation: SLA
