"Revolutionizing Space Manufacturing with Metal 3D Printing"

The Cygnus NG-20 spacecraft, currently docked with the International Space Station, is carrying an experimental 3D metal printer developed by Airbus for the European Space Agency. This printer, capable of melting stainless-steel wire to create objects, aims to address the technical challenges of metal 3D printing in space and could provide astronauts with resilience and self-sustainment capabilities on future space missions. The printer will test its performance in microgravity conditions by printing four shapes, which will be compared to reference prints created on Earth to understand how the space environment affects the printing process. This technology could potentially enable astronauts to repair or augment space structures on otherworldly settlements like the Moon or Mars, reducing the need for costly shipments of spare parts from Earth.
