Washington:Now that the International Space Station has a 3D printer, engineers can design new tools on the ground and then beam them up to space. <\/p>\n
In September, Made In Space shipped a 3D printer to the astronauts at the space station. In November it printed its first object - a replacement part for itself. <\/p>\n
But this is the first time it has printed a specially designed tool on-demand, which is exactly the kind of work its designers hoped it would do. <\/p>\n
\"The socket wrench we just manufactured is the first object we designed on the ground and sent digitally to space, on the fly,\" Made In Space co-founder Mike Chen wrote on his blog on Medium. \"This is the first time we've ever 'emailed' hardware to space.\" <\/p>\n

Why is that so great? Chen and his colleagues were responding to a request from astronaut Barry Wilmore, who needed a ratcheting socket spanner. Until now, that kind of request would take months to fulfil - Wilmore would have had to wait for the next mission to the space station to carry the tool up. <\/p>\n
Instead, Chen and his team designed the spannerfor printing, then sent the design up to the space station by way of NASA. <\/p>\n
\"Because it's a lot faster to send digital data [which can travel at the speed of light] to space than it is to send physical objects [which involves waiting months to years for a rocket], it makes more sense to 3D-print things in space, when we can, instead of launching them,\" Chen wrote. And that means that astronauts can do their work more quickly and for less money. <\/p>\n
The tech could also be a lifesaver: During the infamous Apollo 13 mission, astronauts were forced to build new carbon dioxide scrubbers on the fly out of whatever materials they had on hand. With the lunar module's clean oxygen running out, engineers on the ground raced to design a makeshift solution and relay building instructions to the astronauts on board. But what if they had been able to augment the supplies on board with custom-designed pieces that could be printed at will? <\/p>\n
