Abstract: A method includes applying thermal and/or strain modeling to the CAD representation of an object. In addition, scan path data is generated based at least in part on a result of the thermal and/or strain modeling. A build file comprising the scan path data is generated. The build file comprises instructions that configure an additive manufacturing tool to generate the object according to the scan path data.

Abstract: A method of method of forming or repairing a superalloy article having a columnar or equiaxed or directionally solidified or amorphous or single crystal microstructure includes emitting a plurality of laser beams from selected fibers of a diode laser fiber array corresponding to a pattern of a layer of the article onto a powder bed of the superalloy to form a melt pool; and controlling a temperature gradient and a solidification velocity of the melt pool to form the columnar or single crystal microstructure.
