Stereolithography (SLA), aka photopolymerization, is one of the oldest (patented in 1984) and best understood methods of 3D printing. The principals have remained largely unchanged over time.
In the most basic terms, a lightsource (traditionally a laser) is aimed at particular region of the liquid resin which quickly hardens. Once a layer has been completed the bed of material is recoated with new resin and the process starts again. This results in a strong, isotropic, and attractive part where the resolution is only defined by the size of the laser’s beam.
Our primary production partner will be announced very soon. This exciting new evolution of SLA enables many excellent and fully characterized materials with game changing rates of output.
