ICON and Lennar’s Wolf Ranch community of 100 3D-printed home nears completion in Georgetown, Texas, about 30 miles from Austin. These structures require the massive 45-foot wide, 4.75 ton Vulcan printer to fabricate.
Using a mixture of concrete powder, water, sand and other additives, the printer nozzle squeezes out the concrete mixture onto a brush, building the home up in individual layers, along a pre-programmed path that creates corduroy-effect walls. Each single-story home with three- to four-bedrooms takes around three weeks to finish printing, with the foundation and metal roofs installed traditionally.
No products found.
It brings a lot of efficiency to the trade market. So, where there were maybe five different crews coming in to build a wall system, we now have one crew and one robot,” said Conner Jenkins, ICON senior project manager.
