A fascinating article about the future of home 3D printing:
"The first printed robot may more resemble a paper origami insect than an octopus. It would operate as a digital ugoku (moving) origami capable of locomotion under its own power and even performing preprogrammed physical tasks.
So when will we be able to swap out the ink cartridges in our home printers and print out our own robot? How close are we to being able to print out a robot on a flat sheet of paper, fold along the dotted lines and have it move under its own power?
"Such a capability is somewhat years away and it is difficult to predict how soon. Someone is going to be the first to make such robots and I am not sure if it is not already being investigated," Dr. Bar-Cohen said."
