Dozens of 3D-printed homes have been built across the world – to house a family in the US state of Virginia or members of an impoverished community in rural Mexico. The world’s largest 3D-printed neighborhood is currently under construction outside of Austin, Texas.
The technology could be especially handy in a place like the US state of Maine, where approximately 80,000 new homes will be needed by 2030 to address a shortage, according to a report released last year by three state agencies.
“People can’t find homes, they’re very expensive. We also have an aging population … so there’s less and less people who are electricians, plumbers, or builders,” Habib Dagher, the executive director of the University of Maine’s Advanced Structures and Composites Center (ASCC), told CNN via video call.
He says he’s got a solution. Last month, the ASCC unveiled what it says is the world’s largest polymer 3D printer. Dagher hopes the-so-called “Factory of the Future 1.0” can help address the state’s housing crisis – and revolutionize 3D-home-printing in the process.
“The approach we’ve taken is quite different from what you’ve seen, and you’ve been reading about for years,” he says.
In recent years, 3D-printing has been used to build everything from businesses to bridges to mosques. One non-profit is even working on printing schools in a war zone. Dubai, in the United Arab Emirates, holds the Guinness World Record for the world’s biggest 3D-printed structure and aims to have 25% of new buildings constructed with 3D printing technology by 2030.
