Recently a team from the University of California, Berkeley sent a new 3D printer to space on a Virgin Galactic mission.
3D printing is already being used in the space industry to create rocket engines and many more parts, but experts want to use the technology not only on the ground but also in space. Europe recently launched the first metal 3D printer to the International Space Station, and regular 3D printers have been used on the ISS for a decade. But as 3D printers become more advanced, researchers want to see if these newer versions could be used in space too.
The printer, called SpaceCAL and designed specifically for microgravity environments, had just a few minutes in space but was able to print four test parts in that time. Those test prints included, appropriately enough, a tiny model space shuttle made from a liquid plastic material called PEGDA.

But CAL is also capable of repairing the crew.
That’s because CAL doesn’t only print in plastic. When tested on Earth, it can also print in silicones, glass composites, and biomaterials, which could allow it to create emergency care for the crew as well as their spacecraft. It could even one day print human organs, which is the aim of a new grant for testing out the technology on the ISS. The next step toward this is printing more simple objects like dental crowns or a tool for closing wounds.
And such technology could have other uses in extreme or remote environments on Earth too. “These experiments are really focused on pushing technology for the betterment of everyone,” Waddell said. “Even though it’s for space, there are always tons of ways it can benefit people back here on Earth.”
