Space shelter-centric startup RedWorks has designed a home for Mars and, compared to all the other Mars homes we've seen, this one is very spacious. It would also be 3D printed on site using Martian soil, which RedWorks founder Keegan Kirkpatrick explained to Fast Company:
The existing 3-D printing system they've invented requires only a power source and dirt—or regolith, to use the geological term for the dust covering bedrock—to create any sort of infrastructure you might need to start your life on a new planet. Using a crucible, the printer heats up this dirt, turning it into a kind of concrete. "When you heat up the regolith, it comes out like a molten taffy," he explained. "Once it cools, you can make anything you want: roads, fuel tanks, a habitat."
If that actually works with the Martian soil, it sounds pretty handy. This is certainly not the first time that someone has suggested using Martian soil to 3D print domiciles, but at least RedWorks' stab at it looks more realistic than this one, which involves walking around on giant webs.
