Stereolithography (SLA), conceived by American Chuck Hull (who later became the founder of 3D Systems) in 1986, became the first 3D printing technology to come to market. The process is based on the photopolymerization of UV-sensitive resins using lasers and has since fostered the development of a whole host of new technologies and resin 3D printers, including DLP, MSLA, VLM (from BCN3D), MovingLight (from Prodways) or, more recently, CLIP (from Carbon). Until a few years ago, printers using these technologies were only found in professional labs, but with the rapid growth of the industry, the technology has gained wider popularity and print quality has further improved. The following is a summary of 21 resin 3D printers with outstanding performance in 2022, including desktop printers and more specialized machines.
