An 11-foot-tall 3-D printer is helping to create a community #3Dprinting #Community #Housing

Three-dimensional printing can create nearly any object. A partnership in Mexico is putting that theory to the test, building a village for residents living in poverty.

In a tiny village on the outskirts of Nacajuca, Mexico, builders are creating new homes using a novel tool: an oversize 3-D printer. To build the homes, the printer pours layers of lavacrete, a proprietary concrete mix, one after another in long swirls. One home can be completed in less than 24 hours.

Nearly any object can be printed in 3-D; in construction, it uses concrete, foam and polymers to produce full-scale buildings. The real estate industry is warming to the trend: The construction firm SQ4D listed a 3-D printed house in Riverhead, N.Y., this year for $299,000. It was billed as the first 3-D printed home for sale in the United States, but it was predated by similar projects in France, Germany and the Netherlands.

Speed is only one factor in bringing a village to completion — New Story has teamed up with local officials in Tabasco to bring sewage services, electricity and water to the community.

“I had builders and developers explaining to me how it’s not possible to get concrete to do that, even as I walked them up to our 3-D printed house,” he said. “Now our biggest challenge is we’ve just got to make more printers.”
