A giant 3D printer built two houses in an impoverished, rural part of Mexico last week, breaking ground on what will be the first 3D-printed neighborhood in the world.
The 33-foot printer pipes out a concrete mix that hardens when it dries, building the walls one layer at a time. It takes 24 hours over several days to build two houses at the same time -- that's about two times faster than it takes New Story to build a home with regular construction.
There's no price tag on the homes yet, but New Story says it's working with families to have them pay 20-to-30 per cent of their income. They want people to have a sense of ownership in the community.The printer is named Vulcan II and it was made by ICON, an Austin-based construction technology company. It took three years of prototyping to get a printer capable of this project, the company said.
Taking a printer out of the lab and putting it in the real world was an experiment in itself. Getting Vulcan II to the construction site and dealing with harsh weather conditions has been the biggest challenge so far, he said. The nonprofit staff believes in the promise of what the technology could mean for people who don't have safe shelter. Hagler said safe shelter is "one of the largest crises affecting humanity today."2015 Habitat for Humanity study.
