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.

Abstract: A method of manufacturing a 3D article includes operating a 3D printing system including an elevator coupled to a vertical movement mechanism, and a distance sensor. The elevator includes an elevator actuator. The vertical movement mechanism is coupled to the elevator. The build platform includes a build plate having a lower surface. The method includes loading the build platform onto the elevator, operating the vertical movement mechanism to lower the lower surface of the build platform into a measurement range with the distance sensor, scanning the distance sensor along a lateral axis, concurrent with scanning the distance sensor, receiving a signal from the distance sensor indicative of a plurality of vertical locations along the lateral axis of the lower surface of the build platform, and operating the elevator actuator to adjust a height of the lower surface of the build platform.

Abstract: A three-dimensional (3D) printing system is configured to print a 3D article in a layer-by-layer manner and includes a vertical beam, an elevator, and a build platform. The elevator is configured for vertical translation along the vertical beam and includes an upper support and a lower support. The lower support includes at least one elevator actuator extending upward from an upper side. The upper support has a lower side including a datum surface in engagement with the actuator. The elevator actuator is configured to modulate a position of the upper side of the upper support. The build platform includes a build plate coupled below a support plate. The build plate has a lower side for formation of the 3D article. The support plate has a lower side that engages the upper side of the upper support of the elevator to support the build platform.
