Definition: stereolithography
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.
SL for the Consumer
Stereolithography (SL) was brought down to the consumer level in 2012 by Formlabs with its Form 1 3D printer. In this example, an Eiffel tower is being created by beaming the laser up through the liquid photopolymer tray and curing one layer at a time. (Top image courtesy of Formlabs.)
