Stereolithography – better known as SLA – uses a laser to fuse photosensitive resin into solid objects layer by layer. As one of the earliest 3D printing processes, it’s been used since the 1980s to produce end-use parts, prototypes and concept models, initially within the automotive industries. Today, its use is far broader, and it is proving to be particularly effective in a wide range of industries and applications including medical production and dentistry.
