Abstract
Additive manufacturing systems and related methods are disclosed. In some embodiments, an additive manufacturing system includes a build surface, one or more laser energy sources configured to emit laser energy, an optical phased array operatively coupled to the one or more laser energy sources, and a Risley prism assembly comprising a plurality of wedge prisms. The optical phased array includes one or more phase shifters operatively coupled to the one or more laser energy sources and configured to control a phase of the laser energy. The optical phased array is configured to direct the laser energy towards the Risley prism assembly, and the Risley prism assembly is configured to direct the laser energy towards the build surface.
