Abstract
A method of manufacturing a 3D article includes providing a 3D printing system including a rigid base with a vertical beam, an elevator for translation along the vertical beam, the elevator containing an elevator actuator and a force sensor, a vertical movement mechanism, a build platform including a build plate having a lower surface, a build vessel containing photocurable resin, and a controller. The method includes loading the build platform onto the elevator, operating the vertical movement mechanism to translate the lower surface of the build plate through the resin, the photocurable resin exerting a torque upon the elevator, receiving a signal from the force sensor, operating the controller to compute a force-induced angular discrepancy between the lower surface of the build plate and the horizontal plane, and operating the elevator actuator according to the angular discrepancy to level the lower surface of the build plate.
