Long gone are the times when astronauts had to wait several months for a shipment of new supplies. The International Space Station received a 3D printer in September, courtesy of Made In Space Inc. The printer was put to use in November when it manufactured its first object: a wrench.
The idea came on one occasion when astronaut Barry Wilmore sent a request for a new ratcheting socket wrench. Usually, he would have waited months until the next flight supply would have been sent to the ISS.
