Zusammenfassung:	Aspects are provided for additively manufacturing a build piece using tile-based printing with dynamic beam shaping. An apparatus may include a powder bed depositor that deposits a layer of powder material in a powder bed, a laser beam source configured to produce a laser beam, a beam shaping component configured to adjust an energy profile of the laser beam to obtain a beam energy profile, and a controller. The controller can be configured to obtain information of the layer of powder material and control the beam shaping component to adjust a beam energy profile of the laser beam to correspond to tile energy profiles associated with a plurality of tiles in the layer. Further, the controller can be configured to apply a pulse of the laser beam to the plurality of tiles to fuse portions of the build piece corresponding to respective tiles.
