3D printers have been used to produce various things from vacuum cleaners to artificial ears, but never have they been used to construct a livable home. That’s set to change as Eindhoven in the Netherlands gets ready to become the first city in the world to have habitable homes made with a 3D printer. The Dutch team behind the innovation hope producing homes with 3D printers will revolutionize the construction industry with far more energy-efficient, eco-friendly homes.
