The Chinese company WinSun is hoping to lessen the sting of losing your house in a disaster. Using an absolutely massive custom made 3D printer, 150 meter long, 10 meter wide and 6 meter deep, they are making houses printing wall by wall. They can print an entire village in a day. That is lightning speed. You could have homes for a small city in a week tops. Now they just need to perfect 3D printed food.
