Using a machine which measures a staggering 20 feet tall, 33 feet wide and 132 feet long, the team at WinSun started with a basic CAD drawing which they fed to the massive 3D printer that was able to fabricate the structure piece-by-piece using a specially formulated and patented ‘ink’. The ink, which includes construction waste such as concrete, fiberglass, sand, and a special hardening agent, is an incredible way to recycle general construction materials — not to mention it is flexible, self-insulating, and resistant to strong earthquakes. The walls and other components of the structure were fabricated offsite with a diagonal reinforced print pattern and then shipped in and pieced together. The company then placed beam columns and steel rebar within the walls, along with insulation, reserving space for pipe lines, windows and doors.
Насчет экономичности:
The construction methods, according to the company, are able to save 60 percent of the materials typically needed to construct a home, and can be printed in a time span which equates to just 30 percent of that of traditional construction. In total, 80 percent less labor is needed, meaning more affordable construction, and less risk of injury to contractors.
И видео, в котором, если я правильно понял, говориться о 61 тысяче долларов за постройку такого дома:
С видео видно, что блоки пустые внутри, а это насколько я понимаю обеспечивает хорошую шумоизоляцию.

Что интересует: есть ли у нас(СНГ) такие технологии, вернее, люди, которые этим занимаются. Т.к. ответ скорее всего нет, какие прогнозы: когда будет доступно, насколько цена будет отличаться от строительства обычным способом.
