Perhaps you’ve heard of it, perhaps you haven’t. SLA 3D printing has laser-fine quality (literally) and is becoming increasingly popular for hobbyists, and is a widely used technique the additive manufacturing field.

Stereolithography (SLA) is a form of Vat Polymerization printing. SLA machines work by solidifying resin into a part, layer-by-layer.

 .

The resin can have a variety of properties, but the most important factor is that they are UV-sensitive. This allows the 3D printer to use a special laser, selectively curing areas of resin to build the part.
