The European Space Agency has unveiled plans to "take 3D printing into the metal age" by building parts for jets, spacecraft and fusion1 projects.
欧洲太空总署计划通过制造喷气机、宇宙飞船和焊接零件将“3D打印技术推进金属时代”。
The Amaze project brings together 28 institutions to develop new metal components2 which are lighter3, stronger and cheaper than conventional parts.
Additive4 manufacturing (or "3D printing") has already revolutionised the design of plastic products.
Printing metal parts for rockets and planes would cut waste and save money.
The layered method of assembly also allows intricate designs - geometries which are impossible to achieve with conventional metal casting.
Parts for cars and satellites can be optimised to be lighter and - simultaneously5 - incredibly robust6.
Tungsten alloy7 components that can withstand temperatures of 3,000C were unveiled at Amaze's launch on Tuesday at London's Science Museum.
At such extreme temperatures they can survive inside nuclear fusion reactors8 and on the nozzles of rockets.
"We want to build the best quality metal products ever made. Objects you can't possibly manufacture any other way," said David Jarvis, Esa's head of new materials and energy research.
