How it works:
A UV laser scans over a vat of liquid resin, curing it layer by layer to form the part. The laser moves in the XY plane while the build platform lowers in Z. The diagram shows this process—resin is selectively hardened only where the laser hits, gradually forming solid layers in the liquid.
Where it’s used:
SLA is widely used for high-detail prototyping, casting molds, and end-use parts that demand smooth surface finish and precision. It’s commonly applied in the dental and medical industries for surgical guides and aligners, as well as in consumer product development and jewelry. Thanks to its accuracy and material versatility, it’s also favored in engineering labs, design studios, and small-scale manufacturing.
