Tempe gets first 3D printed house to increase affordable housing stock
By Susie Steckner, Special for wranglernews.com
Habitat for Humanity Central Arizona is building its first 3D printed home in Tempe, seeking to transform affordable housing opportunities.
The one-story custom home, located at 677 W. 19th St., which was purchased by the city for affordable housing, combines 3D printing and traditional construction to create an innovative model for the future : a scalable and profitable home ownership solution. to address the housing crisis facing low and modest income residents of communities nationwide.
âThis is truly a unique opportunity for Habitat for Humanity Central Arizona,â said Jason Barlow, president and CEO of Habitat Central Arizona.
âWhen we consider the housing issues Arizona faces, the need forâ¦ 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 real game-changer. Just think of the implications.
The 3D guided project involves a single family home with three bedrooms and two bathrooms. The living space is 1738 square feet. About 70% of the house is 3D printed, including interior and exterior walls. The rest is of traditional construction.
It is expected to be completed in early fall and could be occupied as early as October.
According to those involved in developing the project, Habitat’s mission to build its first such house in the country started with a German printer and ended on a wasteland in Tempe.
âThis type of innovation doesn’t happen without amazing partners and we are extremely grateful to them,â said Barlow. âBringing people together is at the heart of our mission and in this case, we are bringing together new partners in the form of engineers, architects, developers and others looking for a breakthrough in affordable housing. . “
Habitat Central Arizona and Tempe have been partners for over 30 years. Other current partnerships include the construction of 15 traditional houses on four lots in the city.
“Tempe is known for its innovation, and this groundbreaking project aligns perfectly with our goal of identifying new solutions that accelerate the growth of affordable housing and the workforce in our city,” said the Mayor of Tempe, Corey Woods.
âBy working with valuable partners, we want to make sure that everyone who wants to live in Tempe can do so. Beyond the borders of our city, this project can serve as a model for other communities as we all work to meet the critical needs of families who are truly the faces of this growing housing affordability crisis.
PERI, based in Germany, shipped its 3D printer to the United States in March. It was then flown to Arizona in April, and printing began in Tempe in May.
âOurâ¦ team is incredibly proud to print this house in Tempe for Habitat for Humanity,â said Thomas Imbacher, CEO of Innovation and Marketing at PERI Group.
He noted that since 2016, PERI has been working intensively on the development of 3D construction printing solutions for residential construction. In 2020, PERI produced the very first 3D printed house in Germany with a BOD2 printer, followed shortly after by the largest 3D printed apartment building in Europe.
The 3D printing project in Tempe is now continuing this success story in the United States, added Imbacher.
According to those familiar with the PERI process, it uses a gantry-type setup and is said to be the only second-generation construction printer on the market. The portal system is configured from several modules 2.5 meters in length, width and height.
For those interested in the technical aspects of this new approach, the BOD2 works in three dimensions: the print head moves right and left along the X axis; the X axis moves forward and backward along the Y axis; and the whole XY group moves up and down along the Z columns.
Thanks to this gantry principle, the printer can move to any position inside the structure, moving up the interior and exterior walls layer by layer.
The 3D construction device is certified to allow workers to stay in the printing area during the printing process. This means that manual work, such as laying ducts and empty connections, can be easily incorporated into the printing process. A control unit allows workers to operate the BOD2 via a web interface or a touch screen.
Once the walls of a building are printed, the ceilings can be integrated. These are then built in the traditional way.
Other partners came together to make the project possible, including co-presenting sponsors Cox and Lowe’s, Habitat for Humanity International, Tempe, PERI, 3D Construction, Candelaria Design and The Ramsey Social Justice Foundation.
