Active in the field for years, and since 2012 with the WASP (World's Advanced Saving Project) project focused on the development of 3D printing with Open Source logic, Massimo Moretti and his team of terrible guys have developed a 3 meters high 12D printer capable of print an entire house in clay, and beyond with excellent potential an entire village.
The presentation of the BigDelta (and here the name "Big" really fits it all), which took place some September 19 in Massa Lombarda during a happening halfway between the technological and the convivial, showed in action a machine capable of printing an area of about 20 square meters. At the end of the article there is also the video, take a look at it.
The declared goal is to develop eco-sustainable and zero-kilometer production of low-cost housing units, able to meet the needs of developing populations. With little expense it will be possible to combine the earth with other materials available directly on site and build a house. A step forward towards the "maker economy", an economy model in which everyone can produce what they need, greatly reducing the supply chain and the energy and economic losses that derive from the current economic system.
In the mouth of the bee (and its industrious hive) guys!
