A San Francisco-based startup has used an enormous 3-D printer to build a cozy 400-square-foot house in Russia in just 24 hours.
Apis Cor’s mobile 3-D printer looks a bit like a construction crane, and it used concrete as its “ink” to layer the home’s floor and walls. After that, contractors arrived to install the roof, insulation, windows and other interior features. The total cost amounted to about $275 per square foot, including appliances and furniture.
Some reports speculate that the small houses could be used to quickly provide new homes to those displaced by disasters and other emergencies, or perhaps to solve issues of housing shortages in overpopulated areas.
