Stereolithography or "SLA" 3D printing is an early and widely used 3D printing technology. Stereolithography (SLA) utilizes a vat of liquid photopolymer resin cured by an Ultra Violet (UV) laser to solidify the pattern layer by layer to create a solid 3D model from customer supplied 3D data. The SLA process addresses the widest range of rapid manufacturing applications.https://www.facfox3d.com/3d-printing-service/sla-3d-printing-service/sla-3d-printing.html
