Similar to the 3D printer that can create houses in 24 hours for less than $10,000, the Delta-style 3D printer is revolutionizing the sustainable housing industry.
Developed by the Italy-based World’s Advanced Saving Project (WASP), the Delta-style 3D — also called the BigDelta — is an astounding 40 feet (12 meters) tall. The machine’s inventor, Massimo Moretti, created WASP to “create a means for affordable fabrication of homes, and provide these means to the locals in poverty stricken areas.” According to Quartz, he saw the need for housing and noted the seemingly endless supply of materials such as clay and dirt.
Inspired, he then developed the BigDelta to accommodate the growing need for housing for those that earn less than $3,000 a year. According to the company’s press release, over 4 billion people presently live in that income tier. Additionally, 100,000 new houses will be needed every day within the next 15 years.
The printer is comprised of a collapsible steel frame and a suspended printing nozzle. To create the low-cost homes, BigDelta uses only water, dirt, clay and plant fibers. The materials are locally-sourced and have little to no carbon footprint. With this invention, the task of providing housing to the growing population will undoubtedly become easier.
