Stereolithography (SLA) photopolymer resin 3D printing uses additive manufacturing techniques to produce printed parts out of liquid plastic resin. DLP (Digital Light Processing) SLA 3D printing uses an LED light source with a digital micromirror device (DMD) to project layer-by-layer images onto the build plate to form the final object. Some modern DLP 3D printers now cut out the DMD in favor of a panel of micrometer-sized LED lights. This projecting of the entire layer at once makes it one of the faster photopolymer resin 3D printing technologies currently available. When using SLA technology, it's important to use the right material that is designed to work with DLP curing technology. Check out the collection below of resins by reliable brands like Liqcreate, MakerJuice, SprintRay, PhotoCentric, and more who produce great quality resins that have been successfully tested to succeed with DLP SLA for investment casting, model making, and design applications.
