stereolithography - Computer Definition
The first 3D printing technology. Pioneered by Chuck Hull of 3D Systems, stereolithography (SL) uses a liquid photopolymer that is cured one layer at a time with a UV laser. Stereolithography is used to make parts as large as 20" x 20" x 24", and engineers and industrial designers envision myriad applications for this process. See 3D printing.
