The European Space Agency (ESA) has achieved a significant milestone in space manufacturing by successfully 3D printing the first metal part in space. The metal 3D printer, developed by Airbus and its partners, was launched earlier this year to the International Space Station (ISS) and installed by ESA astronaut Andreas Mogensen in the Columbus module’s European Drawer Rack. In August, the printer produced its first 3D metal component in microgravity.

Returning to Earth for Quality Analysis

ESA plans to send this first product, along with three additional printed components, back to Earth for thorough quality testing. Two of the printed parts will be sent to ESA’s technical center in the Netherlands (ESTEC), one will be used in the LUNA facility at the European Astronaut Centre (EAC) in Cologne, and the final piece will be analyzed by the Technical University of Denmark (DTU). These tests will provide essential data on the quality of 3D printing in space.

Additive Manufacturing Key for Future Space Missions

As missions to the Moon and Mars become more frequent and complex, resupplying spacecraft will be increasingly challenging. Additive manufacturing in space offers a solution by allowing astronauts to create necessary parts, repair equipment, and produce specialized tools on demand. This reduces reliance on resupply missions and increases the autonomy of space crews, a critical advantage for long-duration missions far from Earth.

ESA’s metal 3D printer is the first to successfully operate in microgravity, building on earlier efforts with plastic 3D printing on the ISS. This achievement marks a new frontier in space exploration, demonstrating the potential of manufacturing in space to support long-term missions.
