Abstract: 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.
