All of the examples I can find using this technology are one-story. That's not promising for addressing housing price problems in large cities. But maybe it could be adapted?
My two cents having 0 experience in building construction but having a fdm 3d printer is it's simply a 'market fit' optimization.
It's a pretty new technology, at this point I think you can mainly hope to sell them to enthousiasts. Why bother with the increased complexity and risks of handling more height ? No one would buy multistories building with unproved technology, we have to wait year to see if the structure is really stable 'on often surprisingly complex real conditions'. And probably like 'small' 3d printers : the more maximum volume you want to print, the more cost heavy is the printer.
I'm pretty sure if it prove itself efficient over time, they will try to develop multi-stories buildings.
Yeh I think that's all the 3d printing homes I've seen.
I think one problem is that the printing setup doesn't have a way to put reinforcement in. I'm not sure if that's a problem for 2 story.
Another thing they seem to have here is the gaps for windows; I think they're doing simple U's for the windows, so can't put anything on top of it.
