We have seen 3D printed buildings before but most of them were prototypes, built off-site or not used afterwords, but nothing compares to this house built by Apis Cor.
Apis Cor used a unique house 3D printing machine they developed and made an on-site house in 24 hours for the cost of some 10000 USD. It has surface of 38 square meters (409 square foot) and has been built in Stupino town, Moscow region, Russia.
The finished house is fully livable with all the appliances. Very cool!
