bird bone i saw looked more like if you glued two pieces of something together and then pulled them apart a bit. all stringy in between. very organic.
closest thing i can imagine that we're doing like that today is gas-assist injection molding. but the cross-sections i've seen are just variable wall-section; not stringy like the bone. which is why that one chair structure caught my eye. i was recently sent some samples of some new SLA material. it felt a little like polypropylene.... and it flexed. SLA materials have traditionally been really brittle. i could conceivably create a wing in 3D and rapid-prototype the part just like that chair.
now i think about it, i may have another option using a common manufacturing process. have to think about that some.
