A 3D printed house designed as a model for affordable housing
Is 3D printing the future of affordable housing? It certainly seems possible. Booming technology has the potential to build homes faster and cheaper than traditional building techniques, and has already resulted in a low-cost housing project in Mexico. Today, the global housing association Habitat for Humanity is creating a 3D printed house that it hopes will become a model of affordable housing.
The prototype home is currently under construction in Tempe, Arizona, and is expected to be completed by September and serve as a home for a low-income family. It will have a floor space of 1,738 square feet (161 m²) and will contain three bedrooms and two bathrooms, as well as a living room and kitchen, as well as a garage.
More ambitiously, Habitat for Humanity aims to build on its experience in building homes to produce a series of affordable 3D printed homes. How affordable? We contacted the association and received the following statement.
“We haven’t calculated the full cost of the house yet because almost everything, from the slab to the lighting, has been donated in kind as is often the case with Habitat homes. This first one won’t be cheaper. just because of the time and cost around a “prototype” process like this. Our hope is that because we have been able to prove the technology, others can help us evolve it to be. more efficient and more profitable. “
The house is created in collaboration with formwork and scaffolding company Peri using the same BOD 2 3D printer model used in Peri’s other 3D printed housing project in Germany. The construction process is essentially the same as the other 3D printed architecture projects we’ve covered, involving the 3D printer extruding a cement mixture from a layered nozzle, building the basic structure, with humans doing the rest of the work, like fitting windows and doors, for example.
It will be wired ready for solar power and is scheduled for the LEED green building standard, as well as a IBHS fortified house designation, which was established to prove a building’s resilience to weathering.
“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 think it could be a real game-changer. Just think of the implications. “
While affordable housing seems like the most obvious solution for 3D printing technology, it’s also worth pointing out that there are also projects exploring the other end of the market, like the development in Austin, TX, which includes luxury 3D printed homes starting at US $ 450,000.
