"ESA Sends First Metal 3D Printer to Space for ISS Testing"

The European Space Agency is sending the first metal 3D printer to the International Space Station, with the printer set to arrive on Thursday. This marks a significant advancement in space technology, as metal 3D printing in orbit presents unique challenges. The printer will use stainless steel and a powerful laser to create objects, with four test prints scheduled to compare printing quality and performance in space versus on Earth. If successful, this technology could enable astronauts to produce tools and parts in space, as well as aid in the construction of lunar bases and support missions to Mars.
