Abstract:

A method of applying a plurality of energy beams in the additive manufacture of a component includes a) providing a first and a second energy beam, each set up for the irradiation of a layer of a powder bed, wherein the first beam scans over a first irradiation area and the second beam scans over a second irradiation area, wherein the first and second irradiation areas are substantially arranged adjacent to each other and form part of a manufacturing plane, and b) assigning a scan vector to be scanned in the first irradiation area by the second energy beam, when a melt pool generated by the second energy beam during the scan of the vector is expected to cause less overlap with a powder bed outside of the component's geometry than a melt pool generated by the first energy beam would cause during the scan of the vector.
