Here is yet anothee method of 3D printing houses. A company called United Earth Builders is using an automated process of earthbag construction to increase productivity over 1300%. They use a Bobcat tractor and a specialized attachment to fill earthbags and construct homes. The company is located in California and will be giving classes on the technology next year on a regular basis. More details on this method of pseudo 3D printing can be found here: http://3dprint.com/7716/earthbag-3d-print-house/

Below you will find a picture of an earthbag constructed home. What do you guys think? Could this be a safe and efficient method of constructing 'green' homes?
