In Minnesota, contractor Andrey Rudenko is currently working on a project of gargantuan proportions that seems to be stretching and exploring the limits of 3D printing technology. Using a printer that was substantially modified and expanded, he has printed a concrete castle in his own backyard. And at 3 by 5 meters, this concrete structure is the world's first 3D printed concrete castle, and one of the largest objects that has, up till now, ever printed with 3D printing technology.
Also 3dprint has more details on the capabilities of the printer and some additional information from Andrey.
Go to Andrey's homepage for more pictures of the castle construction, news links and printer details.

Agreed, all solid concrete structures require an internal metal framework for strength.
