Abstract

A method and system for tensioning film tank in a liquid photopolymer container designed for use in a stereolithography (SLA) additive fabrication device is disclosed. The liquid photopolymer container comprises a tank frame, a film clamp that attaches to the tank frame and secures a film between the clamp and the tank frame, and a film positioned between the clamp and the bottom surface of the tank frame. The film clamp and the tank frame include raised-features and recesses that mate together to increase the grip on the film.
