Stereolithography (SLA service) is an additive manufacturing process that belongs to the trough curing family. In SLA, the model is made by selectively curing the polymer resin layer by layer using an ULTRAVIOLET (UV) laser beam. The materials used in SLA are liquid photosensitive thermosetting polymers.
SLA is the most cost-effective 3D printing technology if the model requires high accuracy or smooth surfaces. When the advantages, disadvantages and limitations of the manufacturing process are fully understood, the best results can be printed.
