SLA - Stereolithography

ProZ3D_symbol

Stereolithography is an additive manufacturing process that works by focusing an ultraviolet (UV) laser on to a vat of photopolymer liquid resin. As the laser hits the layer of resin it is hardened into shape dictate by the 3D CAD file. Another layer of resin is then applied and so the process continues that includes adding support material.

Once the part has been printed the support material is remove and the object is clean. The printed object is then placed in a UV oven to cure. Often the printed object is sanded and painted to give a realistic look to a prototype.

Models or parts are printed with cost effective, highly accurate results and can be used as master patterns for moulding techniques.
