3D printing and the future of figures

I was sitting here thinking to myself that I would have loved it if they made a leader class Ratchet for prime because having an Ambulance the same size as a Lancia Stratos or a Camaro.
Of course Ratchet is not going to be as popular as other characters so they didn't make one. Which got me to thinking, what if figures were made to order? You go to the store and look at the figures and if there is one you want they can just print it and ship it to you.
This would eliminate shelf warming and make it possible to have different sizes of figures for people to scale. Also if you missed out on a figure from years ago they can print you a copy no problem.
Same thing with replacement parts- a panel pops off and flies into the abyss, no problemo they can just print another. Lose a sword/gun/teeny tiny thing? Just print an extra, NBD.
