The team behind the project recently joined forces with local craftsmen to print a prototype home in the Italian province of Ravenna and completed its first house at a cost of only around $60. The massive printer uses a mixture of locally-sourced earth and straw which is prepared in an industrial mixing machine. Like icing on a cake, the mixture is then squeezed out of BigDelta’s printing nozzle in predefined patterns.
“Building BigDelta is much more than a dream come true if we consider that, by 2030, international estimates foresee a rapid growth of adequate housing requirements for over 4 billion people living with yearly income below $3,000,” the company writes.
“The United Nations calculated that over the next 15 years there will be an average daily requirement of 100,000 new housing units to meet this demand.” BigDelta could become a viable option to deliver ultra low-cost and effective housing to needy communities and bring the group one step closer to its dream of a world with affordable housing for everyone.
