적층 재료를 위한 방법 및 장치가 설명된다. 적층 제조를 위한 방법은 구축 표면 상의 재료의 층을, 실질적으로 선형 형상을 가지는 적어도 하나의 라인 레이저를 포함하는, 레이저 에너지의 하나 이상의 투사체에 노출시키는 단계를 포함한다. 레이저 에너지의 하나 이상의 투사체가 구축 표면을 가로질러 스캔될 때 재료의 층이 희망 패턴에 따라 융합되게 하기 위해서, 라인 레이저의 세기가 변조될 수 있다. Methods and apparatuses for additive manufacturing are described. A method for additive manufacturing may include exposing a layer of material on a build surface to one or more projections of laser energy including at least one line laser having a substantially linear shape. The intensity of the line laser may be modulated so as to cause fusion of the layer of material according to a desired pattern as the one or more projections of laser energy are scanned across the build surface.
