These 3D printed shelters from AI SpaceFactory were originally conceived for NASA to advance “print” habitats on Mars. Using space-grade technologies NASA materials allow this structure for long-term missions to Mars or in the Catskills. These structures can also solve many housing and shelter problems on earth. They are currently running an Indiegogo campaign where you can book stays for 1 night and up. It’s a good way to get a taste of the future of eco-retreats.
