Fourth Industrial Revolution

Astronauts can now 3D print their own space tools. Here's how

The International Space Station is seen with the docked space shuttle Endeavour in this photo provided by NASA and taken May 23, 2011. The photo was taken by Expedition 27 crew member Paolo Nespoli from the Soyuz TMA-20 following its undocking and is the first-ever image of a space shuttle docked to the International Space Station.

Imagine you’re an astronaut, zooming about in space. Suddenly your spacecraft malfunctions. You could fix the problem immediately, but you don’t have the right tools. Instead you wait days, weeks, even months for replacement parts.

Three-dimensional printing in space could soon make this dilemma a thing of the past. NASA’s first commercial 3D printer is now up and running on the International Space Station and is printing tools.

The Kobalt wrench, as shown below, allows astronauts to carry out essential maintenance work and even has a special fastening feature so it doesn’t get lost in zero gravity.

 The Additive Manufacturing Facility, a commercial 3D printer aboard the International Space Station, printed this wrench (its first tool) in June 2016.

The Additive Manufacturing Facility (AMF) is the result of a partnership between NASA and 3D-printing company Made in Space, and users on Earth can pay to use it to print objects on the space station.

This ability to manufacture tools in space in a matter of hours could revolutionize space travel because astronauts will no longer have to wait for replacement parts to reach them.

It could also make space travel cheaper: NASA estimates that it costs $10,000 to send just one pound of materials into space.

In addition, being able to 3D print objects from space could open up new possibilities for inhabiting other planets.

NASA is currently experimenting on Earth with substances that resemble Martian sand to see whether it could be used as “ink” to 3D print building materials on Mars.

The European Space Agency (ESA) is also looking at whether lunar dust could be used to 3D print an entire moon base. It is already able to print out stone-like building blocks weighing 1.5 tonnes each.
