Just outside Austin, Texas, massive machines are squeezing out 100 three- and four-bedroom homes, in the first major housing development to be 3D-printed on site.
One of the nation's largest homebuilders, Lennar, is partnering with ICON, a 3D printing company, to develop the project.
Lennar was an early investor in ICON, which has printed just about a dozen homes in Texas and in Mexico.
"I think the sort of Holy Grail is where one person can watch a dozen systems you need one person to watch a dozen systems," Ballard said.
