European Space Agency aims to perfect 3D printing of metal parts within five years

Like NASA, the European Space Agency is actively pursuing 3D-printed metal components for use in spacecraft, planes, and even nuclear fusion applications. The ESA has unveiled printed parts made from metal that it says can withstand temperatures of up to 3500°C, far beyond the limits of plastic, the traditional 3D printing ingredient. This makes the resulting parts “fit for space and the most demanding applications on Earth,” according to the ESA.
