Systems and methods for beam scanning for powder bed fusion (PBF) systems are provided. A PBF apparatus can include a structure that supports a layer of powder material, an energy beam source that generates an energy beam, and a deflector that applies the energy beam to fuse an area of the powder material in the layer at multiple locations, the deflector being further configured to apply the energy beam to each of the locations multiple times. A PBF apparatus can include a deflector configured to provide multiple scans to a layer powder material supported by the structure. A PBF apparatus can include a deflector that applies the energy beam to fuse an area of the powder material in the layer at multiple locations, the deflector being further configured to apply the energy beam in a raster scan.
