국제우주정거장(ISS)에서 3D프린터를 활용한 물체 제작이 최초로 성공했다.
3D프린터와 원자재만 챙겨 가면 우주선 정비에 필요한 부품을 지구에서 조달하지 않고도 얼마든지 즉석에서 만들어 낼 수 있다는 이유에서다.
면판에는 나사와 이번 작업을 공동으로 계획한 우주 제조회사 '메이드인스페이스(Made In Space)'의 이름과 나사의 이름이 새겨졌다.

Digital design emailed to zero-gravity printer on International Space
Station and used to produce working ratchet
Guardian staff Astronauts on the International Space Station have used a zero-gravity 3D printer to produce a working socket wrench complete with ratchet action – using digital plans that were emailed to the station by Nasa mission control on Earth. Engineers at Made in Space, which built the experimental printer, overheard space station astronaut Barry “Butch” Wilmore mention on the radio that he needed a socket wrench. The company used computer-aided design (CAD) to draw up plans, produced an earthbound version of the spanner for safety certification by Nasa, then had the plans relayed to the ISS, where it took four hours to print out the finished product. “The socket wrench we just manufactured is the first object we designed on the ground and sent digitally to space, on the fly,” said Made In Space founder Mike Chen. “We designed one in CAD and sent it up to him faster than a rocket ever could have. “It also marks the end of our first experiment – a sequence of 21 prints that together make up the first tools and objects ever manufactured off the surface of the Earth.” The 3D printer was delivered to the ISS two months ago and the first thing it made was a sample component for itself. The space agency hopes to one day use the technology to make parts for broken equipment in space. The company plans to replace the orbiting demo machine with a bigger commercial printer next year. The European Space Agency plans to fly its own 3D printer in 2015. Meanwhile the ratchet and other items made by the ISS printer will be returned to Earth for detailed comparison with corresponding parts produced on the ground. theguardian |
