7 Best SLA Printers in 2021 - Reviews

The SLA 3D printer is one of the first additive printing processes that were discovered in 1986. SLA is an acronym for Stereolithography — a technique that uses photosensitive resin and hardens up under UV light.
SLA or resin 3D printing has become popular, mainly because its price has dropped significantly in recent years. This 3D printer is quite different from the fused deposition modeling (FDM) printer, which uses filament to print off models. Instead, it uses resins and light to make its 3D printed objects.
The resin used for SLA 3D printing is photosensitive, and they solidify when exposed to UV light. This is the simple process involved in creating objects with this kind of printer. They are famous for making quality prints, and they can generate better quality objects than FDM printers, which are costlier.
If you're looking for the best SLA printer you can purchase, you're in the right place. Here, you'll find seven different quality SLA Printers you can buy.
