Here is a robotic 3D printer that can complete large homes in a matter of couple of days. SQ4D’s ARCS robot recently completed a 1900 square feet home in 48 hours using materials costing less than $6000. The robot delivers faster build times by eliminating and consolidating manual labor intensive tasks such as siding, framing, and sheathing.
The above video shows this home 3D printing robot in action.
