As 3D printing technology advances, it never never ceases to amaze me what they’re doing with it. Working firearms, artificial limbs for animals, live tissue organs, and all kinds of other crazy stuff, and the latest achievement emailing objects to space.

According to this report from iflscience.com, NASA emailed a ratchet design to Astronauts aboard the international space station, who in turn printed it, and used it.

It’s absolutely insane to sit and imagine the impact 3D printing will eventually have on our daily lives. From living organs on demand, to instant merchandise in the consumer market, it isn’t hard to imagine that future generations will regard 3D printing as one of the most revolutionary innovations in the history of mankind.
