Scientists on the International Space Station (ISS) have successfully 3D printed a metal part in space - an out-of-this-world first. The achievement is significant, as this 3D fabrication capability is thought to be key for the success of future long-duration missions. Numerous challenges were overcome by the team from the European Space Agency (ESA) to achieve metal in-orbit manufacturing capabilities. The four metal 3D printed components that the scientists plan to make will be returning to earth for thorough quality testing.
The device behind this feat is ESA's own Metal 3D Printer, described as a technology demonstrator. It was built by Airbus and its partners. However, the important work of "designing the printer's melting process and hardware, as well as its laser source, delivery optics, feedstock storage, and feeding system," was undertaken at Cranfield University in the UK, says the ESA press release.
