“The part is something to behold. Thanks for always being a partner that seeks to connect us with the best processes and services available.”

StereoLithography (SLA) is the first choice for producing complex geometries with excellent accuracy and great surface finish. InterPRO operates nine SLA high resolution and large frame SLA systems in-house.

InterPRO’s unique SLA Nano technology quickly produces very small or very large prototypes with incredible accuracy, utilizing a variable-diameter laser beam that focuses to 0.004” diameter for high precise features. InterPRO offers many StereoLithography materials to choose from, including glass clear, high impact strength, high HTD and Class VI medical grade.

StereoLithography works by focusing a UV laser onto a vat of photo curable resin. As the laser draws a shape on the surface of the photopolymer, the resin is solidified and forms a single layer of the desired 3D object. The process is repeated for each layer of the design until the 3D object is complete

Standard build layer height is 0.004″
High resolution build layer height of 0.002″ is also available.

Design SLA parts with the manufacturing process in mind

Save time and money by taking into consideration important SLA  aspects that reduce back-and-forth, improve part , reduce cost, and get parts on your desk faster!

Benefits & Applications

StereoLithography is a top 3D printing technology for producing ultra-clear lenses and bottles. The strength and detail of SLA
models make them the best choice for design verification models, fit check models, appearance models, large housings and master patterns for RTV molding.
