SLA is quite possibly the preferred 3D printing technology for accurate prototyping for designers of any niche where tolerances of parts are paramount. Being able to create accurately formed prototypes (particularly dynamic / moving parts) enables verification that the design will or will not work before committing to any production route. Not only is stereolithography one of the most accurate printing methods, it also provides good durability, along with a clean surface finish. One other factor to note, the size of the print can affect accuracy. For example, conventional FDM printing starts to struggle when printing smaller / tiny objects. However, the resolution of SLA is determined by the spot size of the UV laser and therefore can handle smaller prints with more accuracy.
