What is Low Force Stereolithography (LFS)?

LFS is an improved SLA 3D printing technology that delivers excellent surface quality, accuracy, watertight results, and versatility in creating precise prototypes and end-use parts. Part of the vat photopolymerization family of additive manufacturing processes, LFS works by exposing light-reactive thermoset materials to a laser in order to polymerize and create a solid part.
