About Stereolithography

Stereolithography (SLA) is a 3D printing technology that uses photopolymerization to create solid objects. The process involves using a liquid resin that is sensitive to ultraviolet light. When the liquid resin is exposed to a UV laser, it polymerizes into a solid material. The laser cures the part layer by layer to create the desired shape.

After forming the object, it undergoes additional UV and thermal treatments to improve its strength and durability. The resulting parts are highly accurate and have a smooth surface finish.

Stereolithography is a fast and precise process commonly used to create prototypes, master patterns, and large concept models. Its high speed and design flexibility allow rapid iteration during new product development. In addition, stereolithography printers can create complex geometries that would be difficult or impossible to achieve with traditional manufacturing techniques.
