The SL process as originally commercialized for “industrial” applications and represented in UnionTech stereolithography 3D printers utilizes a build platform that is immersed in a vat of photopolymer creating a layer of polymer formulation ranging from 0.002 in. to 0.010in. A 355 nanometer wavelength laser draws the cross-section of the prescribed layer with instantaneous curing of the photopolymer. The platform then lowers to the desired layer thickness and a recoater passes over the platform to ensure a uniform layer of photopolymer for the next cross-section.
