Abstract
An additive manufacturing apparatus includes a platform, a dispenser to dispense a plurality of layers of feed material on a top surface of the platform, and an energy delivery system. The energy deliver system includes a light source to emit a light beam, and a reflective member having a plurality of reflective facets. The reflective member is positioned in a path of the light beam to receive the light beam and redirect the light beam toward the top surface of the platform to deliver energy to an uppermost layer of the layers of feed material to fuse the feed material. The reflective member is rotatable such that sequential facets sweep the light beam sequentially along a path on the uppermost layer.
