StereoLithography (SLA)

Produce Complex Geometries with Excellent Accuracy and Great Surface Finish.

High-Resolution Prototypes and End-Use Parts

StereoLithography (SLA) is the first choice for producing complex geometries with excellent accuracy and the best surface finish. InterPRO offers SLA ultra-high resolution and ultra-large SLA-printed parts with a choice of materials to meet your project needs.

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 solidifies and forms a single layer of the desired 3D object. The process repeats for each layer of the design until the 3D object is completed.

InterPRO’s SLA technology produces incredibly small and extremely large prototypes with incredible accuracy, utilizing a variable-diameter laser beam that refocuses every millisecond to define high-precision features. InterPRO offers many StereoLithography materials to choose from, including glass clear, high-impact strength, high heat-resistant and Class VI medical grade.

“The part is something to behold.

Thanks for always being a partner that seeks to connect us with the best processes and services available.”

“I just received the SLAs!

Nice! Thanks so much for the quick turnaround!”

“SLA is an ideal choice...

where the prototype needs high resolution of fine details.”

“A rapid prototype part allows me to design and produce tooling and fixturing...

without worrying about the limiting factors of conventional machining (i.e., 5-axis machining, line of sight, deep-drilled holes, etc).”

InterPRO StereoLithography Benefits & Applications

StereoLithography is the best 3D printing technology for producing highly clear parts, such as lenses and bottles. The strength and detail of SLA models make them the most popular choice for design verification, checking fit, highly detailed appearance models, and electronic housings, as well as patterns for RTV molding and casting. Very fast delivery is standard.
