ESA Achieves First 3D Metal Printing in Space

The European Space Agency successfully printed the first metal part aboard the ISS, paving the way for in-orbit manufacturing.

ESA and Airbus collaborated to create a 3D metal printer capable of functioning in microgravity.
The printer uses stainless steel wire and a laser to create metal parts, which are then remotely controlled from Earth.
Safety measures include operating the device in a sealed, nitrogen-filled box to prevent oxygen interference.
This advancement aims to reduce reliance on resupply missions by allowing astronauts to manufacture tools and parts on-demand.
The first batch of printed shapes will return to Earth for detailed analysis and quality assessment.
