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.

Abstract: A ventilation and cooling system for a selective deposition modeling apparatus dispensing a curable material. The ventilation and cooling system captures airborne contaminants in the apparatus making the apparatus suitable for use in an office environment. A pressure drop is established within the apparatus to assure that all air that enters the apparatus passes through a filter which captures the airborne contaminants before the air is expelled from the apparatus. Sensors are provided to assure that the ventilation and cooling system is function properly, and if not, the apparatus is either shut down or a signal is provided to the operator indicating that the system is not functioning properly.
