Let's dive deep into the fascinating world of desktop stereolithography, exploring its technology, applications, and advantages.

Understanding Stereolithography Technology

Stereolithography, commonly known as SLA, is a form of 3D printing that utilizes ultraviolet (UV) light to cure liquid resin into hardened plastic. The process begins with a vat filled with photopolymer resin, where a build platform is submerged just below the surface of the liquid. A UV laser then traces the cross-section of the object layer by layer, illuminating specific areas of the resin to trigger the curing process. This layer-by-layer approach allows for incredibly high-resolution builds and complex geometries that may be challenging or impossible to achieve with other additive manufacturing methods.

One of the primary advantages of SLA is its ability to produce smooth surfaces and intricate details. The curing action of the UV light results in phenomenal layer adhesion, which ensures that pieces fit together seamlessly.
