Home builder Lennar and construction-technology company Icon plan to start building the largest three-dimensionally (3D)-printed home community in the U.S. next year.

The 100-house development near Austin, TX, will test the technology's ability to manufacture homes and spark buyer demand on a bigger scale.

Icon's Jason Ballard said the 3D-printed homes are built around concrete framing rather than wood, and the company's printers can generate the wall systems for a 2,000-sq.-ft., one-story house in a week.

Lennar said Icon needs just three workers on site when printing a wall system, instead of the six to 12 framers and drywall installers needed for conventional construction.
