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 assembly. The energy delivery assembly includes a light source to emit one or more light beams, a first reflective member having a plurality of reflective facets, and at least one second reflective member. The first reflective member is rotatable such that sequential facets sweep the light beam sequentially along a path on the uppermost layer. The at least one second reflective member is movable such that the at least one second reflective surface is repositionable to receive at least one of the at least one light beam and redirect the at least one of at least one light beam along a two-dimensional path on the uppermost layer.
