“We’re happy to show how two men and a machine can easily build a cozy 3D earth shelter in a very short amount of time, with extremely low expenses”. Massimo Moretti, founder of WASP and creator of the Shamballa Technology Parc in Ravenna, Italy, put a 12 meters high BigDelta 3D printer into service for earth architecture.

Here some data. They were printed 270 cm of clay and straw with a 5 meters diameter wall, using about 40 tons of material. With 135 layers in total, 300 pounds each: each layer is completed in 20 minutes circa. As for consumption, we are talking about two cubic meters of water and 200 kWh, which means 32 euros for energy, 3 euros for water, 10 euros for straw, 3 euros for the motor hoe’s gas: 48 euros in total. To save even more money, the material can be mixed by feet, reducing energy costs up to 90%.

The final wall is of excellent quality. From preventive analysis it appears that it may withstand great efforts, while the large amount of fibers guarantees a good sealing. The weight/performance ratio resulting from straw and clay seems not to require further reinforcement of the walls systems. To prevent the external consumption, a 10% of plaster has been added to the mixture. Once the wall will be four meters high, the roof and door will be mounted.
