Two 3-D replicas of a glove worn by European Space Agency astronaut Hans Schlegel. The one on right is lifesize and the other at one-tenth scale. The models were created “using fused deposition modelling of thermoplastic”, ESA stated, at a mechanical workshop at the Netherlands’ European Space Research and Technology Centre.

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
