Stereolithography (SLA)
Industrial grade resins for general prototyping, functional parts and master patterns
High-Detail Industrial Resins
Parts built in 2-5 business days
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 Lab's industrial SLA offers one of the largest build envelopes commercially available, capable of producing parts up to 1500 mm (59 inches) in length with the industries highest print tolerances. 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.

Accura Xtreme White 200
Exceptionally Strong & Durable
Accura Xtreme White (XTW) is an exceptionally tough industrial grade resin offering both strength & rigidity for demanding applications. Accura XTW is a highly versatile resin that is ideal for a number of applications including concept models and functional assemblies that require high fatigue resistance such as snap fits & enclosures. The outstanding surface finish and detail makes this resin also ideal for creating master patterns for vacuum casting & molding.
