What Is Stereolithography?
This industrial process offers the industries highest precision and speed with minimal need for support structures and post processing. 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.
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). Layers are cured by ultraviolet laser through a process called vat photopolymerization to solidify the pattern layer by layer.

Design Guidelines | Stereolithography
Stereolithography (SLA) is one of the oldest manufacturing process that uses a vat of resin, cured by a high powered UV laser to form a solid structure. The machine begins curing layers on the surface of the resin, curing each cross section by the set layer height of 50-100 um. After each layer, the parts drops down into the vat of liquid resin which acts as a support structure for the part. The process repeats itself with the top 50-100 um layers of resin being cured selectively by the laser.
This design guidelines covers specific design parameters, which will need to be followed to prevent build failures from occurring. We have set the minimum allowed tolerances specified by our engineers and the manufacturer to ensure your parts build successfully and on schedule.
Optimizing your designs for Stereolithography help keep manufacturing costs down. Price is primarily based upon the volume of resin consumed to manufacture your parts as well as the X, Y, & Z extents of your part which affect the run-time cost. Small, hollow parts are priced the most competitively in Stereolithography. It is important to keep your wall thickness and hollow out any dense sections of your part.
Stereolithography offers the largest build volume of any 3D Printing technology with a capacity of: 1500 x 750 x 550 mm (59 x 30 x 22 in.), and a standard layer thickness of 50-100 um depending on the size of your part.
