Recently in Shanghai, a Chinese company 3D-printed 10 small buildings in about a day.

Granted, these buildings are not the most sexy. You could even argue they're not real 3D-printed buildings since assembly is required. (Rest assured a team from Amsterdam is currently at work on a fully 3D printed canal house). But according to The Architect’s Newspaper, the company hopes the technology will provide an “affordable and dignified" housing option for the impoverished.
