NASA is developing 3D-printed chain mail to protect ships and astronauts

ai0o5vcpwa7ejasy0s3r.jpg

Chain mail was an essential tool for medieval warriors hoping to avoid a quick (or slow) death by a sword. But NASA engineers hope a similar material, with a few modern upgrades, could prove to be just as useful for spacecraft and astronauts looking to survive the rigors of outer space.

The biggest improvement NASA has made in its twenty-first century version of chain mail, developed by a team led by Raul Polit Casillas at the Jet Propulsion Laboratory in Pasadena, California, is how it’s manufactured. Instead of a medieval blacksmith spending weeks painstakingly connecting tiny loops of metal, one by one, the material shown above and below is 3D printed by a machine, which means it could be produced as needed on the space station, or on other off-Earth habitats, depending on where we travel in the coming decades.
