What is 3D Resin Printing?
The following is an excerpt of a knowledge article written for PrototypeHubs.com. To read the full article, click the link at the bottom of the page.
Stereolithography (SLA), Digital Light Processing (DLP), and Liquid Crystal Display (LCD) are 3 different types of 3D resin printing. In these vat polymerization methods, light sources are used to cure liquid resin, layer-by-layer, to form a desired 3D model. Although SLA, DLP, and LCD all use a light source, a build platform, and a vat of resin, each process uses a different type of light source.
SLA 3D Resin Printing
SLA, the original form of 3D printing, was patented in 1986. In this technique, galvo mirrors focus an ultraviolet (UV) laser that solidifies the cross-section of each layer, point-by-point. In general…
