분말 베드를 이미징하기 위한 2차원 에너지 패턴화 시스템을 포함하는 적층식 제조 시스템이 개시된다. 개선된 챔버 디자인, 다수의 챔버, 분말 취급 및 재사용 시스템, 및 분말 특성화 방법이 개시된다. A method and an apparatus of a powder bed fusion additive manufacturing system that enables a quick change in the optical beam delivery size and intensity across locations of a print surface for different powdered materials while ensuring high availability of the system. A dynamic optical assembly containing a set of lens assemblies of different magnification ratios and a mechanical assembly may change the magnification ratios as needed. The dynamic optical assembly may include a transitional and rotational position control of the optics to minimize variations of the optical beam sizes across the print surface.
