World's Largest 3D-Printed Neighborhood Nears Completion in Texas

ICON, a construction technology company, is nearing completion of 100 3D-printed homes in Wolf Ranch, Texas, using a massive robotic printer. The 45-foot-wide, 4.75-ton Vulcan printer began constructing the walls of what ICON claims is the world's largest 3D-printed community in November 2022. The printer extrudes a concrete mixture layer by layer, creating corduroy-textured walls. ICON senior project manager Conner Jenkins told Reuters the process is faster and more efficient than traditional construction, requiring fewer workers and reducing material waste. The single-story homes, priced between $450,000 and $600,000, feature concrete walls resistant to water, mold, termites, and extreme weather. However, homeowners reported weak wireless signals due to the thick walls, necessitating mesh internet routers. ICON, which printed its first home in Austin in 2018, is also developing lunar construction systems for NASA's Artemis program.
