For Fine, Detailed Small-Featured Parts and Extraordinarily Large Components

Stereolithography (SLA) uses a UV laser that cures parts one layer at a time in a photo-reactive epoxy resin. It is widely regarded as one of the most accurate of the additive technologies.

The Stereolithography 3D printing process is a popular choice among engineers looking for fine detailed, small-featured parts as well as extraordinarily large components.

With both large-format and high-resolution SLA equipment, we can build parts as fine as .002” layer thickness on our high-resolution equipment virtually overnight from a customer’s CAD data.

We also offer a range of resins to meet each rapid-prototyping need.

Benefits

High resolution: parts at .002”–.006” layers
Large, seamless parts: can be bonded together with UV light–reactive resins
Precision: fine features from a precise spot-beam UV laser
Clarity: waterclear models (in our Somos® WaterShed XC 11122 resin)
