The low-tech practice of building homes using earth bags seems to be keeping pace with the most up-to-date 3D printing technologies. The Earth Home Builder is a skid-operated machine that can “3D print” entire homes by filling earth bag tubes at a rate of 400 feet per hour.

United Earth Builders, a collective of earthbag and natural builders that are dedicated to building affordable and accessible housing, has developed a method of 3D printing houses with earth bags. The Earth Home Builder is outfitted with specialized earth home building technology and can fill earth bag tubes of many sizes at a rate of up to 400 feet per hour. A crew by hand can manage to fill about 30 feet per hour, depending on bag width, which makes the new technology far superior.

The company is now looking to partner with non-profit organizations in order to implement the technology by building truly affordable houses. The team will hold an EHB project course in Weitchpec, California, on 30 June, 2014.
