    摘要: An additive manufacturing system (100) includes a foil supply drum (150), a melting energy source (180), and a processor (300). The foil supply drum is configured to be rotated for dispensing a foil sheet (400) over a substrate surface (280) supported by a build element (260). The melting energy source is configured to direct one or more melting energy beams (182) onto a non-melted region (402) of the foil sheet located over the substrate surface. The processor is configured to execute computable readable program instructions (304) based on a three-dimensional digital definition (306) of the object (416), and control the melting energy beam to selectively melt at least some of the non-melted region into melted portions (404) forming a material layer (412) of the object onto the substrate surface while separating the melted portions from non-melted portions, and command rotation of the foil supply drum for dispensing the foil sheet during manufacturing of the object in correspondence with the digital definition.
