Stereolithography (SLA)
Overview
Stereolithography (SLA) uses UV light to cure liquid resin into solid layers, producing fully isotropic parts with exceptional detail, smooth surfaces, and tight tolerances. It’s the ideal choice for high-precision applications, visual prototypes, and production-quality components. Resin-printed parts are also naturally watertight due to their fully solid, non-porous layers.

Frequently asked questions
Here are some common questions about our SLA Printing services.
SLA printing uses UV light to cure liquid resin into solid layers, producing parts with far smoother surfaces, finer details, and tighter tolerances than FDM.
Yes — SLA parts are fully solid and isotropic, offering consistent strength in all directions. Depending on the resin used, they can be optimized for toughness, flexibility, heat resistance, or precision.
Absolutely. SLA prints are naturally watertight thanks to their solid, non-porous layers, making them ideal for parts that need to contain or resist fluids.
