Abstract
This invention relates to rapid prototyping systems, specifically, a continuous moving surface liquid resin system (CMSL) and fast printing method for making any 3D objects, such as dental devices, including but not limited to artificial teeth, dentures, orthodontic appliances, aligners, splints, veneers, inlays, onlays, copings, frame patterns, crowns and bridges and the like. 3D printers, such as DLP or stereolithography printer, are used to cure polymerizable material in a layer-by-layer manner to build-up the object rapidly and continuously.
