Scientists have developed a zero-gravity metal 3D printer for space

With the International Space Station ‘s Additive Manufacturing Facility (AMF) in full swing, the concept of having a 3D printer in space is becoming increasingly familiar. Despite these advances, however, there are still a number of hurdles and challenges that must be met in order for additive manufacturing to be used to its full potential in the cosmos. Metal 3D printing, for instance, remains a difficult task, but one that could prove essential for maintaining equipment and creating parts necessary for journeys to Mars.”
