Zusammenfassung:	Systems and methods of adapting the geometrical shape of a laser beam in laser-based powder-bed fusion (PBF) are provided. An apparatus for laser-based powder-bed fusion includes a depositor that deposits a plurality of layers of a powder material. The apparatus further includes a laser beam source that generates a laser beam having a variable beam geometry. A laser application component applies the laser beam in one of a plurality of beam geometries to fuse the powder material to construct a build piece.
