Are the following statements still true, or are they now out of date?
[3D printed architecture] The problem is this: No one has been able to successfully take the leap from printing a fancy art pavilion to printing a functional building, and it’s still not clear if the technology is going to save the world or be another decorative footnote of architectural history.
For whatever reason, the only printed buildings that look remotely habitable have been built by Chinese companies. But just because they look habitable doesn’t mean that they are. No one lives in these houses, and when you get close enough, they don’t really look like the kind of place you’d want to live, unless you have a thing for creepy-cave chic.

I'm not wanting to argue about the architectural concern for appearance. As an engineer my concern is with structural integrity and reliability. However, are people living in 3D houses? That is the common concern.
