THREE-DIMENSIONAL PRINTING SYSTEMS FOR RAPIDLY PRODUCING OBJECTS
First Claim
1. A method for making a three-dimensional object comprising the steps ofa. loading a polymerizable liquid resin material or heated resin material as a liquid into a resin bath (vat) of a 3D printer;
- b. locating one or more mechanical arms at clear and/or transparent window proximate to the bottom of the resin bath to maintain a liquid interface between a build surface and the clear and/or transparent window proximate to the bottom of the resin bath;
c. applying sequential voxel planes into the liquid resin or the heated resin to form a first layer of material, which polymerizes into a solid; and
d. applying one or more successive layers of the polymerized material continuously until a predetermined shape is formed.

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.
