Handy! 3-D Printing Could Build Moon Bases And Improve Items Used In Space

Star Trek replicators, here we come. The European Space Agency has released a list of how 3-D printing could change space exploration forever. And lest you think this type of printing is far in the future, images like those disembodied hands above show you it’s come a long way. Those are 3-D replicas of a glove worn by European Space Agency astronaut Hans Schlegal.

The applications range from the small — making lighter valves, for example — to ambitious projects such as constructing a moon base. Below are some ESA images showing uses for 3-D printing, and if they’ve missed some, be sure to let us know in the comments.

Two valves -- which is the 3-D printed one? It's the one on the right. The original (left) is a water on-off valve (Woov) flown on the European Space Agency's Columbus module on the International Space Station. The replica is 40 percent less massive. Credit: ESA

    I hope that good use of these developing technologies can be made in the near future to speed and reduce the cost of the construction of bases on other worlds using materials extracted in situ.
