One of the nation’s largest homebuilders is backing 3D-printed homes to solve countries’ increasing housing costs and climate-related natural disasters. Lennar (NYSE:LEN), the country’s second-largest homebuilder, has teamed up with 3D home printer Icon to build 100 new homes in Georgetown, just outside Austin, Texas.

“We have a durable product that’s wind-resistant from hurricanes. It’s fire-resistant,” Stuart Miller, executive chairman of Lennar, told CNBC. The ability to adapt modern products to what we need for the future in housing, to build a healthier housing market, is amazing.”

3D Printers Can Manufacture Two Homes Per Week, Working 24 Hours Per Day

Using 11 printers, Icon manufactures two homes per week, with each one doing the job of more than a dozen construction workers, CNBC reported. The homes in Wolf Ranch were designed by architect Bjarke Ingels. The system pumps out concrete floor plans 24 hours per day, with the roof being the only part of the house that is not 3D printed. All the homes in the Lennar community are solar-powered. Lennar is currently working on its second 3D printed community, about 7 miles from its first, which will have twice as many homes built at a lower price point. 

Not Impacted By Tariffs and 30% Cheaper

According to CNBC and other outlets, there are multiple advantages to using 3D home printing technology:

• The homes offer an alternative to regularly constructed homes that tariffs could impact.
• All the concrete used in the Icon-built communities is sourced domestically.
• There is a choice of 3D Home printing companies, including Alquist 3D, Apis Cor, and CyBe Construction.
• Homes constructed using 3D printers are estimated to be around 30% cheaper to build than traditional homes.
• The 3D-printing construction industry is forecasted to generate total revenues of $40 billion by 2027.

A Boost For Affordable Housing

One sector set to benefit from 3D-printed homes is affordable housing. Habitat for Humanity is already using the technology to mass-produce housing, a model that could develop across all housing sectors.

“In the future, I believe robots and drones will build entire neighborhoods, towns, and cities, and we’ll look back at Lennar’s Wolf Ranch community as the place where robotic construction at scale began,” Icon CEO Jason Ballard said when the company and Lennar announced Wolf Ranch in November 2022. 

Finishing Choices

Whilst the cake-icing look of 3D homes might take some getting used to, homeowners can finish the interiors by smoothing over the concrete ridges with paster, adding wood furring strips and sheetrock, manufactured shiplap, or simply painting the concrete.

Multistory Buildings, Low Emissions, And Building On The Moon

According to All3dp.com, Icon has developed a new 3D printer, the Phoenix, which enables multi-story construction because of its vast reach. The Phoenix uses a new material called CarbonX, which is praised for its low emissions. The cement-like product comprises South Texas-sourced materials that further limit emissions due to low transportation costs. The company’s website states they plan to use the material to build all homes.

According to the New York Times, NASA is investing in 3D homes and plans to build them on the moon by blasting a printer into space and using specialized lunar concrete created from rock chips, mineral fragments, and surface dust.. 

“We’re at a pivotal moment, and in some ways, it feels like a dream sequence,” Niki Werkheiser, NASA’s director of technology maturation, told the Times. “In other ways, it feels like it was inevitable that we would get here.”
