Additive Manufacturing

Stereolithography and Digital Light Processing

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. 

Digital light processing is a similar technology to stereolithography, but the two processes can produce very different results. While stereolithography printers use two motors to aim a laser across the print area, solidifying resin along the way, digital light processing printers use a digital projector screen to flash a single image of each layer at once – forming a whole layer at once.
