If it was 1 story house of that size less than week to get it framed from a decent crew. The pictured house here was a single story house. Also this 3d print for multi-story building would probably not be much faster since unless both the first and second floor shared the same interior wall layout they would have to stop and make a floor for the interior of the second floor. Plus the weight of concrete means those second floor interior walls would be conventional framed anyways. Unless you want to make the floor extremely expensive to carry that kind of load...

The print time needs to be added to the printer setup time. Something that big will have non-trivial effort to get on site and set up and then tear down after the print.

If that takes six days and the print takes a day then the printed house takes half the time of traditional framing. An improvement but not a revolution.

Concrete has additional issues though with weight being significant. Soil that can support a wood framed house can't necessarily support the same size concrete house. At least not without additional compaction. That just adds to pre-construction time and permitting.
