SLA 3D printers are able to deliver highly detailed, tiny parts just a few mm in size, all the way up to 1.5 m long parts—all at the same exceptional resolution and accuracy. Even large parts remain highly accurate from end-to-end, with virtually no part shrinkage or warping.
SLA is all about precision and accuracy, so it is often used when form, fit, and assembly are critical. The tolerances on SLA parts are typically less than 0.05 mm, and SLA offers the smoothest surface finish of any additive manufacturing process. With the quality SLA can achieve, it is particularly useful for creating highly precise casting patterns (e.g., for injection molding, casting, and vacuum casting) as well as functional prototypes, presentation models, and form and fit testing. SLA technology is extremely versatile and can be used in any number of areas where precision is paramount
