Well, even though they aren't printed in-place and have facade pieces to cover up the layer look, these are definitely exciting proof-of concept pieces. The technology may not have as much application in the West, but China has had a real need for consistent building standards, and a need to move away from brick construction. (for social reasons I won't go into)

I can see 3D printed buildings becoming an iconic architectural style in China (and perhaps other similar countries) in the next decade.
