This is video of a 3D-printed, Arduino-controlled animatronic tail.  It’s a great example of design following nature, with vertebrae and tendons being modeled by mechanical substitutes, and while you might be able to replicate this version of the design with more traditional prototyping methods, the 3D printing makes it both easier to duplicate and easier to reconfigure.  And a few of the improvements I can imagine, such as making the vertebrae interlink like biological ones to be more firmly linked to one another would be really tricky with hand tools, but pretty easy on 3D printing…
