소스 에너지를 효과적이고 효율적으로 이용하기 위해 고효율, 에너지 빔 패턴화 및 빔 조향에 관한 적층 가공 방법 및 장치가 제공된다. 일 실시예에서, 원치 않는 광의 리사이클링 및 재사용은 하나 이상의 광 밸브에 의해 생성된 다수의 광 패턴의 소스를 포함하고, 다수의 광 패턴 중 적어도 하나는 거부된 패턴화된 광으로부터 형성된다. 이미지 릴레이는 다수의 광 패턴을 지향시키기 위해 사용되며, 빔 라우팅 시스템은 다수의 광 패턴을 수신하고 이들을 각각 분말 베드상의 한정된 영역으로 향하게한다. 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.
