Italy’s WASP (World’s Advanced Saving Project) aims to help the world’s impoverished by 3D-printing sustainable dwellings using all natural materials. Unveiled at the Maker Faire Rome, the portable 3D printer called the Delta can be transported to areas in need to print homes on site. The printer works with locally-sourced materials like mud and fiber to create structurally sound homes with a culturally-sensitive, vernacular aesthetic.
Unlike other 3D printing companies, WASP has turned its attention to natural and local materials, rather than quick printing plastics, to create healthy new homes. Their new home-printer is a tall three-armed machine, which is held together with lightweight ratcheting straps and can be assembled in two hours. When disassembled, it can easily be transported in a vehicle, enabling it to travel from place to place with ease.

Inspired by the long tradition of building homes from clay, mud and fibers in Morocco, the Delta takes the labor out of the building process to create needed shelters in a snap. Local dirt and clay is collected and sifted into a fine powder, mixed with water, then fed into the collapsible machine. A WASP-designed structural shape is chosen, then the machine slowly begins to print, stacking layer upon layer until the structure is complete. Like traditional clay building, the home is then dried in the sun before it is occupied.
