What is SLA 3D Printing?

Stereolithography (SLA) is a resin-based 3D printing process that uses an ultraviolet laser to cure liquid photopolymer layer by layer. It is one of the most accurate and versatile additive manufacturing technologies, capable of producing highly detailed prototypes and functional parts with excellent surface finishes.

High-resolution printing for fine details and smooth surfaces

Excellent dimensional accuracy and tight tolerances

Wide range of functional and aesthetic resin materials

Ideal for prototypes, dental models, and end-use parts

Short lead times for low-volume production

How Does SLA 3D Printing Work

SLA 3D printing begins by forming the support structures, followed by the part itself, using an ultraviolet laser to trace each layer on the surface of a liquid photopolymer resin. After a layer is cured, the build platform lowers and a recoating blade spreads a fresh layer of resin. This process is repeated layer by layer until the part is fully built.

Once printing is complete, the part is removed from the build platform and cleaned in a lab using solvents to eliminate any uncured resin. The support structures are then carefully detached, and the part undergoes an additional UV-curing process to ensure optimal strength and stability. Finally, the component is ready for customized surface finishing.
