3-D printers that could crank out parts for spacecraft and space stations – from wrenches to screws – all while in orbit is becoming one step closer to reality.
A company called Made in Space has completed a successful testing period of two 3-D printers on multiple NASA flights, with a scaled-down wrench becoming the first-ever tool printed in partial zero gravity.
Printing out parts in space could eventually be transplanted to other worlds such as the moon, where it could help human colonies gain a foothold by printing out robot parts or buildings, piece by piece.
