“As with any desktop 3D printer, the Vulcan printer pipes layer by layer to build an object – except this printer is more than 45 feet (13.7 m) wide, weighs 4.75 tons and prints residential homes.

This summer, the robotic printer from ICON is finishing the last few of 100 3D-printed houses in Wolf Ranch, a community in Georgetown, Texas, about 30 miles from Austin.

ICON began printing the walls of what it says is the world’s largest 3D-printed community in November 2022. Compared to traditional construction, the company says that 3D printing homes is faster, less expensive, requires fewer workers, and minimizes construction material waste…

The single-story three- to four-bedroom homes take about three weeks to finish printing, with the foundation and metal roofs installed traditionally.
Jenkins said the concrete walls are designed to be resistant to water, mold, termites and extreme weather…

The 3D-printed homes at Wolf Ranch, called the ‘Genesis Collection’ by developers, range in price from around $450,000 to close to $600,000. Developers said a little more than one quarter of the 100 homes have been sold.”
