What Is Stereolithography And How Does It Work?

Stereolithography, an innovative additive manufacturing technique, offers a precise method for fabricating three-dimensional objects from digital models. This process begins with the selective curing of liquid photopolymer resin using ultraviolet (UV) light, which solidifies the material layer by layer. Initially, a computer-aided design (CAD) model is sliced into thin horizontal cross-sections; subsequently, each slice corresponds to a specific layer that will be created during printing. As the build platform descends incrementally into the vat of resin after each layer is cured, this coincidental layering enables intricate designs and fine details to emerge in the final product. Furthermore, stereolithography distinguishes itself from other 3D printing techniques through its ability to produce high-resolution parts with smooth surface finishes and complex geometries. The application of this technology spans various fields including prototyping in engineering, medical modeling for surgical planning, and even custom jewelry fabrication, showcasing its versatility and impact on modern manufacturing processes.
