Abstract: Methods and systems for additively manufacturing an object having an overhang feature. The system includes an array of platform segments forming a deposition surface. The system includes a plurality of elongated beams each connected to a platform segment. The system includes a moving platform configured to attach to a portion of the plurality of elongated beams and elevate the attached elongated beams. The system includes an additive manufacturing device configured to deposit material onto the deposition surface. The system includes an actuator configured to move the moving platform vertically. The system includes a controller configured to cause the additive manufacturing device to deposit the material onto the deposition surface and cause the actuator to move the moving platform upward to cause the elongated beams and their respective connected platform segments to form a support structure for the overhang when the overhang is fabricated by the additive manufacturing device.
