摘要： A method of printing a three-dimensional part includes dividing each of a plurality of layers of a model of the three-dimensional part into a plurality of passes, where each of the plurality of passes is separated from one or more adjacent passes by a gap. The gap between passes in a first layer is offset from the gap between passes in an adjacent layer, such that the gap between passes in the first layer does not align with or stack with the gap between passes in the adjacent layer.

摘要： A slot extruder for use with an additive manufacturing system, which includes a plenum configured to receive a photocurable resin, an elongated slot positioned at a bottom end of the plenum and configured to receive the photocurable resin from the plenum, one or more resin inlet ports extending into the plenum, and one or more mechanisms configured to controllably pressurize and depressurize the photocurable resin in the plenum.

摘要： A laser assembly for use with an additive manufacturing system, which includes a base block configured to be moved along a scan direction axis in the additive manufacturing system, a plurality of laser emitters preferably arranged in an array of at least two rows of two or more laser emitters. At least a portion of a heat sink assembly is configured to draw heat away from the base block and/or the laser emitters. The assembly includes a controller assembly a controller assembly configured to control a movement of the base block along the first axis and to independently control at least timing and duration of energy emitted from each laser emitter of the plurality of laser emitters as the base block moves along the first axis.
