Cross country road trips and voyages to outer space have at least one thing in common -- bringing along baggage is a hassle. Researchers working to minimize the cargo that space travelers will need to carry in the future are, quite naturally, looking to 3D printing as a solution.
After all, why bring a tool box along when you can just print the contents of one as needed? A team of materials scientists at Washington State University
is taking that tactic a step further, though, using material found in moon rocks in a 3D printer
-- an advance that could one day mean that if you need a screwdriver on the moon, you can scoop up a handful of dust and print one at a moment's notice.
