Comment: NASA has a 3D printer on the

NASA has a 3D printer on the Space Station (although quite different than the one's posted here) that is capable of printing necessary parts while out in space. Tools, Screws, Connectors.. whatever they need.

And did you check out Thingiverse.com? They have all the screw drivers, wrenches tools and things that you need.

Just do a search for tools and see what all pops up. Anyone can download and print almost anything they want from there.

NASA has already tested a 3D printer on the International Space Station, and recently announced its requirement for a high resolution 3D printer to produce spacecraft parts during deep space missions. The US Army has also experimented with a truck-mounted 3D printer capable of outputting spare tank and other vehicle components in the battlefield.

As noted above, 3D printers may also be used to make future buildings. To this end, a team at Loughborough University is working on a 3D concrete printing project that could allow large building components to be 3D printed on-site to any design, and with improved thermal properties.

Another possible future application is in the use of 3D printers to create replacement organs for the human body. This is known as bioprinting, and is an area of rapid development. You can learn more on the bioprinting page, or see more in my bioprinting video or the Future Visions gallery.
