When you do it yourself, building a tiny house of around 400-square-feet typically takes a couple months (depending on the design) and costs tens of thousands of dollars in materials.
A San Francisco-based housing startup called Apis Cor says it can do the same job much faster and for a lower price. It recently built its first home near Moscow in just one day with $10,134 worth of materials.
The secret? A 3D-printing robot.
Working with Russian home-building company PIK Group, the house was constructed at Apis Cor’s test facility in Stupino, a town south of central Moscow.
Before the construction, Apis Cor programmed the 3D printer to construct a rounded house. The machine applied cement layer-by-layer to form the shape of the house.
The bot left a small gap between the interior and exterior of the walls, where the team then placed fiberglass reinforcements and sprayed a polyurethane-based mixture for insulation….more here
