Stereolithography (SLA), also known as resin 3D printing, is a 3D printing technology that produces parts with high resolution and accuracy, fine details and smooth surface finishes. Part of the vat photopolymerization printing family, SLA technology uses photosensitive thermoset polymers to produce custom parts. We use Formlabs materials for rapid prototyping and 3D Systems Accura materials for large-scale production.
