Stereolithography or SLA is a mature and stable 3D printing technology that produces highly accurate, high resolutions parts with an excellent smooth finish. The combination of high speed, low-cost per part and well-established materials makes stereolithography an ideal choice for rapid prototypes and low volume production.
Stereolithography (SLA) is a resin-based 3D printing process that starts with a vat of liquid photopolymer resin. A high-precision UV laser selectively cures and solidifies the resin to form the first layer. Once complete, the build platform lowers, and the process repeats layer by layer to create a solid part.

SLA (or stereolithography) is a plastic 3D printing process that uses light-reactive thermoset materials called “resin.” The process offers a wide range of plastic material options that are often categorized by different material properties, including:
Yes, SLA is increasingly being used for functional 3D printing, not just visual models. Modern industrial SLA printers offer advanced engineering-grade resins such as Somos® Taurus™ that have good mechanical properties and higher strength, making them suitable for functional prototypes and some end-use components.
SLA and DLP are two distinct 3D printing technologies that both fall under the same “vat photopolymerization” family and share some similarities. The main difference is the light source: SLA uses a laser beam to cure the resin, while DLP uses a projection system with LED lights.
