Stereolithography (SLA)

Engineering Grade Resins

Stereolithography (SLA) is a 3D Printing method that uses a large vat of liquid photopolymer resin. Layers are cured by ultraviolet laser through a process called vat photopolymerization to solidify the pattern layer by layer. This industrial process offers the industries highest precision and speed with minimal need for support structures and post processing.

Forge Labs uses 3D System's industrial SLA machines which offer the largest build envelopes commercially available, capable of producing parts up to 1500 mm (59 inches). SLA is an ideal process for printing prototypes, master patterns, tools, molds, dies, jigs, fixtures or any application where surface finish, accuracy and product aesthetics are critical.
