Standard Resin, Mammoth Resin, Gray Resin and Transparent Resin use the veteran of 3D printing technologies: Stereolithography
. It’s been around at Materialise since 1990, and continues to be one of the most widely-used 3D printing technologies for plastic models. Stereolithography is a laser-based technology that uses a UV-sensitive liquid resin. A UV laser beam scans the surface of the resin and selectively hardens the material corresponding to a cross section of the product, building the 3D part from the bottom to the top. The required supports for overhangs and cavities are automatically generated, and later manually removed.
