A method for adaptively forming a three-dimensional component, the method comprising:
- simultaneously controlling a plurality of electron beam sources to direct a plurality of electron beams onto a plurality of deposited metallic powder layers to sequentially consolidate patterned portions of the plurality of deposited metallic powder layers to adaptively form the three-dimensional component having a single crystal structure, wherein controlling comprises directing each of the plurality of electron beams onto a different region of the plurality of deposited metallic powder layers, focusing each of the plurality of electron beams onto a portion of each of the different regions, and moving the focused electron beams within the different regions and moving comprises randomly moving the focused electron beams within the different regions.
