Taking a look to the tons of videos regarding CES 2015, I found this one:
This guy was born without an hand and thank to a 3D printed hand and some sensor attached on his arm muscles, he can finally have a second hand! This could never be possibile 10 year ago and will be much more disruptive in the next 10 years.
Imagine you can print your own special hand directly at home, fitting the special work you’re doing. Human evolutions through 3D printed body parts at home, like in the Schismatrix Sterling novel.
Possibility is the power.
