In an additive manufacturing process, a part is formed by using UV light to cure resin contained in a cassette. This lift is intended to manipulate these cassettes during the assembly and quality check steps of their manufacture. A rotating gripper was designed to securely hold the cassette and easily invert it. A deflection compensation “tilt” module allows precise positioning of the cassette on a granite work table, and a spring overload safety module prevents damage to the cassette from lift overtravel.
