These $10,000 Concrete Homes Are 3D-Printed in Less Than 24 Hours


What makes housing so expensive? Labor costs, for one. According to a 2014 Census Bureau survey, the average single-family home takes about six months to construct, and that's a lot of man-hours. A new type of home from Austin, Texas-based startup ICON and the housing nonprofit New Story is hoping to change that. Their homes can be built from the ground up in 12 to 24 hours, and they cost builders just $10,000 to construct, The Verge reports.


ICON's construction method uses the Vulcan 3D printer. With concrete as the building material, the printer pipes out a structure complete with a living room, bedroom, bathroom, and porch that covers 600 to 800 square feet. That's a little less than the size of the average New York apartment and significantly larger than a typical tiny home.


The project, which was revealed at this year's SXSW festival in Austin, isn't the first to apply 3D printing to home construction. Moscow, Beijing, and Dubai are all home to structures assembled using the technology. What makes ICON and New Story's buildings remarkable is what they intend to do with them: Within the next 18 months, they plan to set up a community of 100 3D-printed homes for residents of El Salvador. If that venture is successful, the team wants to bring the printer to other places in need of affordable housing, including parts of the U.S.


ICON wants to eventually bring the $10,000 price tag down to $4000. The 3D-printed houses owe their affordability to low labor costs and cheap materials. Not only is cement inexpensive, but it's also sturdier and more familiar than other common 3D-printed materials like plastic. The simple structure also makes the homes easy to maintain.


“Conventional construction methods have many baked-in drawbacks and problems that we’ve taken for granted for so long that we forgot how to imagine any alternative,” ICON co-founder Jason Ballard said in a release. “With 3D printing, you not only have a continuous thermal envelope, high thermal mass, and near-zero waste, but you also have speed, a much broader design palette, next-level resiliency, and the possibility of a quantum leap in affordability."


After printing and safety tests are completed, the first families are expected to move into their new 3D-printed homes sometime in 2019.
