Abstract

An apparatus for additive printing is provided. The apparatus includes a print head, an optical-mechanical assembly, and a rejected energy handling device. The print head includes an energy source and one or more energy patterning devices configured to provide one or more two-dimensional patterned incident beams to process a powdered material. The optical-mechanical assembly includes optical components arranged to receive and direct the one or more incident beams into a location. The rejected energy handling device is configured to reuse beam energy rejected by the one or more energy patterning devices by relaying the rejected beam energy to either or both of an electricity generator and a thermal management system.
