Abstract
A powder bed fusion system includes a plurality of individual build chambers, with each individual build chamber including an area laser scanner optical device and a point laser scanner. A single, area beam delivery system and the plurality of build chambers are moveable relative to each other, such that the area beam delivery system may be positioned to provide an area scanning laser beam to any of the area laser scanner optical devices in any of the plurality of build chambers. The point laser scanners may be used to contour an edge of an object, and the area scanning laser beam may be used to fill in large areas of the object.
