Abstract
A method and an apparatus for additive manufacturing pertaining to high efficiency, energy beam patterning and beam steering to effectively and efficiently utilize the source energy. In one embodiment recycling and reuse of unwanted light includes a source of multiple light patterns produced by one or more light valves, with at least one of the multiple light patterns being formed from rejected patterned light. An image relay is used to direct the multiple light patterns, and a beam routing system receives the multiple light patterns and respectively directs them toward defined areas on a powder bed.
