Provided are a component and an additive manufacturing method for fabricating a component. The additive manufacturing method for fabricating a component includes providing a first wire segment and a second wire segment, the first and second wire segments each having a cross-sectional stackable geometry; positioning the first wire segment into an alignment with the second wire segment to form a workpiece stack, the alignment aligning adjacent surfaces in a line of sight direction; and directing an energy beam toward the first wire segment and the second wire segment along the alignment to weld the first wire segment to the second wire segment to form a welded stack. The component includes a workpiece stack comprising a plurality of wire segments welded together along aligned adjacent surfaces.
