摘要
In some cases, an additive manufacturing (AM) system includes: a process chamber for additively manufacturing a component, the process chamber having: a build platform; at least one melting beam scanner configured to emit a melting beam for melting powder on the build platform; an applicator for applying layers of powder to the build platform; and a reservoir for storing powder; and a control system coupled with the set of melting beam scanners, the control system configured to: apply the melting beam to a layer of powder on the build platform along a primary melting path; and apply the melting beam to the layer of powder on the build platform along a re-melting path after applying the melting beam along the primary melting path, the re-melting path overlapping a portion of the primary melting path and applied only in an area proximate a perimeter of the component.
