Stereolithography is the first commercialized 3D printing technology, invented by 3D Systems’ Co-Founder and Chief Technology Officer Chuck Hull in the 1980s. It uses an ultraviolet laser to precisely cure photopolymer cross-sections, transforming them from liquid to solid. Parts are built directly from CAD data, layer-by-layer into prototypes, investment casting patterns, tools, and end-use parts.
Once the SLA printing process is complete, SLA parts are cleaned in a solvent solution to remove any residual uncured resin from the part surface. Cleaned parts are then cured in a UV oven.

Tolerances on SLA parts are typically less than 0.05 millimeters, making it an excellent choice when precision is your top priority. Delivering the smoothest surface finish of any additive manufacturing process, the quality of SLA parts makes this versatile technology great for:
Similar aesthetics and properties to injection-molded ABS
Look and feel of polypropylene
Including the industry’s highest clarity material for polycarbonate-like parts
Resins specifically formulated for QuickCast sacrificial patterns for investment casting
Heat deflection temperatures up to over 215c (419f) offering exceptional performance under extreme conditions
Options for jewelry-specific casting and dental model production
SLA 3D printers are able to deliver highly detailed, tiny parts just a few mm in size, all the way up to 1.5 m long parts—all at the same exceptional resolution and accuracy. Even large parts remain highly accurate from end-to-end, with virtually no part shrinkage or warping.
