In rural El Salvador, a family living on $1.90 a day might live in a makeshift house with dirt floors, thin walls, and no running water. But next year, dozens of those families will move into one of the world’s first communities of 3D-printed homes.

New Story, a Silicon Valley-based nonprofit whose leaders have spent the last few years rethinking how to build safe housing for those living in extreme poverty, worked with Icon, a construction tech company, to create a 3D printer that can build a house in a day for roughly $4,000. The printer, called the Vulcan, will be unveiled at SXSW today, along with a 3D-printed home that now stands in an Austin backyard.
