A Dutch construction company called Van Wijnen is 3D printing the first homes in the world that are actually habitable (i.e. able to pass a home inspection). Dubbed Project Milestone, the futuristic homes will be 3D printed near the city of Eindhoven. Currently, there are five houses in total, each with a unique shape and size that shows off the flexibility of the cutting-edge tech. Since the printer is essentially a giant concrete nozzle that moves along a two-dimensional track high up in the air, architects are able to design homes in pretty much any shape they like. Right now, the homes are printed in pieces off-site, then transported to their final destination. Towards the end of the project, the team hopes to make further adjustments by bringing the printer on-site.
