An American company says it has completed the firstpermitted 3D printed home in the United States.
The home was shown to reporters and visitors at theSouth by Southwest technology conference andmusic festival. The event took place earlier this month in Austin, Texas.
Building company ICON has developed large 3D printers that build homes with mortar, a hardand strong material. ICON uses robotics, computer software programs and advanced materialsto make houses.
Jason Ballard is the company’s co-founder.
"So I’m standing in front of the first permitted 3D-printed home in America. This house wasactually printed in high winds, blowing dust and rain."
It is important for the printing process to operate in extreme conditions, such as weatherdisasters. The goal is to print homes in developing countries.
ICON’s 3-D printer is made of lightweight aluminum, and measures 4.5-meters tall by 9 meterswide. The homes are printed on-site, so the equipment has to be light enough to move fromone property to the next.
Ballard imagines that someday, many 3-D printers will operate around the world to makehomes. "It’s actually a lot more simple to build a printer than it is to build a house," he said.
"We ran this printer at about a quarter speed to print this house, and we were able to completethe house in less than 48 hours of print time."
Ballard says that at full speed, the printing process could take as little as 12 hours.
ICON has teamed up with a not-for-profit group called New Story. Together, they areattempting to help provide a quick, cheap housing solution for the millions of people who needit most.
Brett Hagler is founder and chief executive officer of New Story.
"The magnitude of the problem that we face is so big, it’s about a billion people that don’thave one of life’s most basic human needs, and that’s safe shelter."
Hagler says his organization already works on housing needs with poor families in differentareas. But he says that to really make a difference, the program will need to greatly expand.
He added that since the 3D printing process is so much faster than traditional homebuilding, awhole community could be built in just a few months.
"That has to come through significantly decreasing cost, increasing speed, while doing thatwithout sacrificing quality."
Hagler notes that a 3D printed home costs a lot less than a traditional home.
"Traditional style, one of New Story’s homes, is about $6,500 per home, right. We believe overtime, we can get the new home below $4,000."
The goal is to bring the new building technology to the world’s poorest and underserved first.
New Story is currently working with local nonprofits, governments and families to help raisemoney. It plans to start 3D printing homes in El Salvador later this year.
