Abstract:
An improved trough module for an apparatus to manufacture a three-dimensional (3D) object is provided. The trough module (12, 300, 400, 500) includes a movable trough element (55, 200, 700), which comprises a trough frame (202, 303, 406, 506, 703) with a transparent sheet (63, 208, 306, 706) of polymer material and a trough frame actuator (85, 419, 519, 708). The trough frame and the transparent sheet of polymer material are used for retaining a liquid material (15) that solidifies under the influence of light (76). The transparent sheet is provided for receiving at least one pattern (600, 612, 614, 616, 618, 622, 624, 626, 628) of light, wherein each pattern corresponds to a layer of the three-dimensional object (607). The trough frame actuator acts to tilt the trough frame and the transparent sheet. The trough element also includes a flattening device (71, 309, 403, 403', 503, 708) for pressing the transparent sheet and a flattening device actuator.
