One of the many challenges of colonise Mars is that the planet is lacking many of the raw resources we rely on here on Earth . We ’ll need to fetch as much of what we need to survive as potential , but you may only compact so much into a spaceship . So scientist are develop ways to use at least one of the red planet ’s most abundant resources : junk .
We ’ve had a strong metre coming up withreasons as to why everyone needs a 3D printerhere on Earth , but on Mars the car could be used to fabricate tools , spare part , even entire social organization , habitats , and fomite , given there ’s no hardware stores for astronauts to chitchat if we eventually mail homo on the 34 million mile journeying . But 3D printers do n’t make things out of slender air .

You ’ve probably find an affordable consumer - friendly 3D printer at work , melt and extruding thin lengths of plastic to work up up a model . There ’s no plastic on Mars , however , and packing miles of filament on a ship select up valuable blank that could be better used for transport O , water , and other essentials . So scientist atNorthwestern University ’s McCormick School of Engineeringhave developed a agency to rick extraterrestrial materials , like Lunar and Martian junk , into a 3D printing material .
While Martian meteorites kicked up from cosmic collision have made their way to ground , giving us some thought of what the red planet is made of , we do n’t have physical samples of the grime and dust covering its surface . or else , the Northwestern scientists have relied on NASA - approved simulants — aka fake detritus — that the space agency uses for its own testing intention that match the shape and size of the tiny particles that make up Martian debris .
When shuffle with a series of bare answer and a biopolymer developed by the investigator that bind the debris together when dry , the fabric can be extruded with a 3D printer to create whatever Martian colonist happen to require . The printing process is n’t alone dependent on material find on Mars , but object can be produced that are made of over 90 percent junk , reducing the amount of raw cloth a starship want to haul .
3D printing still has a tenacious manner to go before astronauts impossibly far from home can swear on it for survival . A political machine screwing up after 20 hours of printing is annoying here , but could mean life or death for off - worldly concern colonists . However , it might finally be one of the safe cock for quickly do up a feasible establishment , without requiring spaceman to plan and pack for every potential scenario once they land .
