Abstract
A powder bed fusion system is provided. The system comprises a build area with a movable build plate. Two powder overflow and extraction (POE) chambers flank the build area on opposite sides. Two dispensing chambers flank the POE chambers, opposite the build area. Two reservoir chambers flank the dispensing chambers, opposite the POE chambers. A recoater device is configured to move build material from the dispensing chambers or reservoir chambers to the build area. An energy source is configured to generate an energy beam. An energy beam positioning device is configured to selectively direct the energy beam within the build area. A controller is programmed to control, according to a 3D model of a part, the energy source, energy beam positioning device, recoater device, build plate, and vertically movable plates within the POE chambers, dispensing chambers, and reservoir chambers.
