Process works by curing liquid photopolymers when exposed to ultraviolet light. Prototyping Service | Stereolithograph (SLA) is limited in its range of applicable materials but is still widely used for conceptual designs, Product verification, Pattern making, Form/Fit analysis and light functional testing.

The Prototyping Service | Stereolithograph (SLA) process produces plastic parts directly from 3D CAD model, by solidifying the surface of a liquid photo polymer layer by layer with the help of a laser beam. When the laser beam hits the liquid, it solidifies the resin. When a layer is fully traced, the elevator is then lowered in the vat. The self-adhesive property of the material causes the layer to stick with each other and in this way a 3d part is formed in multi-layers.
