This is a video of the world's first house 3-D printed entirely on location with the Apis Cor concrete printing machine. The Apis Cor can be transported to a construction site and print a 38 square meter (~410 square feet) house in about 24 hours for around $10,000. For reference, my apartment is about 65 square feet and I both cook and sleep in the bathtub, which is also my office.
Keep going for two videos, a short one and a long one.
Thanks to Tank, who could drive right through that, no problem.
