1. A method, comprising:
removing a portion of a part to create a first surface;
adding a section to the part, the section including an overhung section that lacks structural support in a portion thereof, the adding including:
positioning a second surface of the part substantially horizontal;
sequentially layering a first plurality of material layers on the second surface extending in a first direction, wherein the sequential layering of the first plurality of material layers creates an extension of the first surface;
rotating the part to position the first surface of the part substantially horizontal; and
sequentially layering a second plurality of material layers on the first surface of the part and the extension thereof extending in a second direction, different from the first direction, the second plurality of material layers meeting with the first plurality of material layers,
wherein the first plurality of material layers and the second plurality of material layers collectively approximate dimensions of the section including the overhung section and are non-coplanar relative to one another; and
machining the first plurality of material layers and the second plurality of material layers to form the section including the overhung section.
