Abstract: An apparatus for peeling in the production of three-dimensional objects is provided. The apparatus, disposed underneath a transparent bottom separation layer of a tank of a stereolithography apparatus allowing light from a light source to pass through the tank to solidify the liquid photopolymer contained in the tank, includes a tilt plate, a pivot connector, and a tilt actuator to move the tilt plate to separate an underneath support for the transparent bottom separation layer from the transparent bottom separation layer to create a slack of the transparent bottom separation layer of the tank to ease the peeling process in producing 3D objects.
