Abstract
An additive manufacturing system includes a platform, a dispenser to dispense a plurality of layers of feed material on a top surface of the platform, a light source to generate a first light beam and a second light beam, a polygon mirror scanner, a galvo mirror scanner positioned adjacent to the polygon mirror scanner, and a controller. The controller is coupled to the light source, the polygon mirror scanner and the galvo mirror scanner, and the controller is configured to cause the light source and polygon mirror scanner to apply the first light beam to a region of the layer of feed material, and to cause the light source and galvo mirror scanner to apply the second light beam to at least a portion of the region of the layer of feed material.
