An experimental 3D printer will melt steel to create new objects... in space

The ISS is now equipped with a 3D printer capable of theoretically shaping new objects by melting stainless-steel wire.

This experimental printer, designed by Airbus and ESA , serves as a means to test and address the technical challenges associated with metal 3D printing in space.

It holds the potential to provide astronauts on future space exploration missions with innovative resilience and self-sustainment capabilities.
