Stereolithography (SLA) 3D printing is the most prevalent resin 3D printing process that produces high-accuracy, isotropic, and waterproof prototypes and end-use parts in a variety of sophisticated materials with precise features and a smooth surface finish.
Stereolithography is a member of the vat photopolymerization family of additive manufacturing processes, also referred to as resin 3D printing. A laser or projector is used to cure liquid resin into rigid plastic. The positioning of essential parts like the resin tank, construction platform, and light source is what distinguishes one product from another physically.
SLA parts offer the high resolution and precision, the finest details, and the cleanest surface finishes. However, the main advantage of stereolithography is its adaptability.
