Abstract
An additive manufacturing system includes a platform to support an object to be fabricated, a dispenser to deliver a plurality of layers of a feed material over the platform, a controller configured to store digital data representing a pre-defined pattern, a laser configured to generate a laser beam to impinge an outermost layer of the feed material and coupled to the controller to fuse the feed material in the pre-defined pattern, and a plurality of independently controllable infrared lamps, each infrared lamp directed to a different section of an outermost layer of the feed material.
