Scientists print 3D metal parts in space for the first time — a key ability for long-distance long-duration missions

Scientists on the International Space Station (ISS) have successfully 3D printed a metal part in space – an out-of-this-world first. The achievement is significant, as this 3D fabrication capability is thought to be key for the success of future long-duration missions.
