  • Rapid prototyping and manufacturing system and method
    Patent number: 7520740
    Abstract: A stereolithography apparatus having a resin vat with resupply containers in one-way flow communication and a leveling container in two-way flow communication, an automatic offload cart to remove and replace build support platforms, an elevator assembly for supporting and releasably retaining a build platform removably attached to the stereolithography apparatus frame such that elevator forks supporting the build platform can be released into the vat and removed from the stereolithography apparatus with the vat, and a recoater assembly and recoater blade for mapping the resin surface in the vat and applying a fresh coating of resin to a cross-section being built in the vat.
    Type: Grant

  • Stereolithographic apparatus
    Publication number: 20060078638
    Abstract: An improved stereolithography apparatus for forming three-dimensional objects using multiple chambered resin vats and a quick disconnect mounting system to permit concurrent use of multiple photopolymer build materials and easy change over of resin vats is disclosed. The apparatus permits easy change over from multiple chambered vat use to single chamber vat use and vice versa or change over between multiple chambered vats.
