That's what I'm thinking. It won't be the material per se, but the design. Making complex inner geometries, and fusing different materials at different locations will change things. Imagine being able to build a tube with internal structure that is impossible to machine. Or having a tube that is part steel, part aluminum, part titanium, all in the right places. This is all possible, and in the early stages of development. (And some aren't even that early in the development.)
