Habitat for Humanity, a nonprofit dedicated to poverty reduction, is about to start 3D printing affordable housing in Tempe, Arizona.
Using a COBOD BOD 2 concrete 3D printer, the organization works with a construction company PERI and several other local partners to 3D print a single family home with three bedrooms and two bathrooms. Once completed, a family selected by Habitat will be chosen to live in the house.
“This is truly a unique opportunity for Habitat for Humanity Central Arizona,” said Jason Barlow, president and CEO of Habitat Central Arizona. “When we consider the housing issues Arizona faces, the need for affordable homeownership solutions becomes clear. If we can deliver decent, affordable and more energy efficient homes at a lower cost, in less time and with less waste, we believe that could be a game-changer. Just think of the implications.
The shortage of affordable housing
According to Habitat, there is an “acute” shortage of affordable housing in Arizona, and the lack of affordable housing options is at an all time high in the Phoenix metropolitan area. In order to solve the problem, the organization turns to concrete 3D printing on site. By dramatically reducing construction times and eliminating the need for manual labor, partners believe technology could be a scalable solution to the problem.
Conceived by Candelaria Design Associates, the 3D printed home will have 1,722 square feet of living space and will be ready for occupancy in September of this year. The BOD2 3D printer, which has a build volume of 40 x 50 x 25 feet, has already been installed at the Tempe construction site. In addition to the 3D printed walls, the building will also feature an asphalt roof and a usable garage with an aluminum door.
3D concrete printing around the world
With each construction project, COBOD further asserts itself as a leader in 3D concrete printing technology. PERI was selected for the project because of the company’s extensive experience in operating BOD2 in Europe. In 2020, the system was used to 3D print the very first market-ready house in Germany, followed by the continent’s largest 3D printed apartment building.
Abroad, BOD2 has also participated in projects in Africa, the Middle East, North America and Asia. More recently, a construction company Printed trusses used the system to fabricate Florida’s first 3D printed building in January of this year. The rebar reinforced storage unit had a floor space of 784 square feet, and the company is now seeking approval to create two additional Florida inter-coastal villas.
Henrik Lund-Nielsen, Founder and Managing Director of COBOD, concludes: “We are truly delighted that our printers are now starting to make a bigger breakthrough in the US construction market. More and more American companies are realizing that our technology is superior to what local suppliers can provide. Our printers have already built buildings in two US states and more will follow in the coming months. “
