NASA and Made in Space was recently able to successfully email the designs of 3D-printing socket wrench to an ISS astronaut Barry Wilmore, it has been reported.
It was mentioned that scientists and engineers on the ground can now design whatever the astronauts might need, and send the file directly to the 3D printer aboard the ISS to be printed and used immediately, CNet reported.
The wrench, as well as the 20 other objects that have been 3D-printed on the ISS thus far, would be sent back to Earth for further analysis to predict how well things printed in space would hold up in the future.
