3D-PRINTED HOMES

- Icon Vulcan II 3D printer

Icon’s giant 3D

printer can build the walls of a small house in 24 hours, cutting traditiona­l constructi­on time in half and saving costs. Earlier this year, the startup 3Dprinted homes inside a community for the homeless near Austin. As the printer rolls back and forth on its tracks, it squeezes out Icon’s custom material in layers to create walls, replacing a home’s traditiona­l structure, insulation, and sheathing—and reducing labor costs. (The foundation, roof, windows, and other parts of the house are built traditiona­lly.) “We’ve also begun our first experiment­s in placing the mechanical, electrical, and plumbing systems into the print,” CEO Jason Ballard says.
