stereolithography (SLA)

Stereolithography (SLA) parts offer the most accurate type of fit/form prototype for the verification of any design before committing to your chosen production route. It is often considered the pioneer of the additive manufacturing processes with the first production system introduced in 1988 and patented by 3D Systems founder Charles (Chuck) W. Hull. The SLA additive manufacturing process uses a vat of photopolymer resin which is then cured by Ultra Violet (UV) laser to solidify the pattern layer by layer to create a solid 3D model. Once the model is complete, the SLA platform rises out of the vat and the excess resin is drained. The model is then removed from the platform, washed of excess resin, and then placed in a UV oven for a final curing. After curing SLA parts are then ready for post processing as required by the specific application. Stereolithography’s high accuracy and good surface finish makes it the preferred choice for many applications including designer models, engineering verification and master patterns for silicone rubber molds, snap-fit assemblies, and automotive styling components.
