We are going to be able to continuously vary the composition of matter for any given part, from the smallest electronic device to the largest beam in a bridge. We are not going to be buying alloy XYZ in plate, rod. billet, or any other form. We will go to our neighborhood materials supplier, and we will purchase precursors or custom compositions of matter. Maybe these will be mono-sized cubes (tetrakaidecahedrons are more likely) of some small size.
