If printers can be used to make prosthetics and topographic maps, why not use homes then?
The US NGO Habitat for Humanity provides funding to architecture firms to build 3D-printed homes for families in need.
A spokeswoman for the NGO said “many local organizations” Habitat for Humanity “are looking at new ways to increase housing construction.” Habitat for Humanity believes that 3D printing of homes is an emerging technology that has the potential to increase our impact on affordable housing. »
So far, the NGO has helped build three 3D-printed homes: two in the United States and one in India.
Tvasta Manufacturing Solutions built the first 3D-printed house* in collaboration with the Habitat for Humanity team in Chennai, India, in November 2020. They have printed a 56-square-meter concrete dwelling in 30 days and hope to reduce the construction time to nearly five days.
This technology reduces building material waste, costs 30% less than other types of construction and can withstand high winds and rain.
A 3D-printed home in India “has a lower carbon footprint not only during the construction process, but also throughout its life,” Adithya Jain*, co-founder and CEO of Tvasta Manufacturing Solutions, told Reuters.
A year later, the NGO funded the construction of a house in Williamsburg, Virginia, by Alquist, a 3D printing company based in Maryland, the first of its kind in the United States. Habitats for Humanity also funded the construction of a third 3D-printed home, this one in Tempe, Arizona, which was completed in March.
