Abstract

An additive manufacturing system includes a platen having a top surface to support an object being manufactured, a feed material dispenser to deliver a plurality of successive layers of feed material over the platen, an energy source positioned above the platen to fuse at least a portion of an outermost layer of feed material, and a coolant fluid dispenser to deliver a coolant fluid onto the outermost layer of feed material after at least a portion of the outermost layer has been fused.
