Stereolithography is one of the most widely used additive manufacturing technologies. Stereolithography uses light to cure liquid resin into a solid object, one layer at a time. This offers dimensional freedom and complexity. Stereolithography can be used for a wide variety of applications including functional prototyping and rapid tooling. The technology excels at creating applications with fine features and high detail, as well as a smooth, injection mold-like surface finish. Stereolithography printers can be used to print many small intricate parts, or detailed large parts.
