A quartet of houses designed by local firm Logan Architecture and built from 3D-printed concrete by construction tech company ICON has completed in Austin, Texas.
The four dwellings have ground-floor walls built using ICON's Vulcan construction system, which uses a robotic armature to layer Portland-cement-based material Lavacrete into striated surfaces.
"3D-printing technology provides safer, more resilient homes that are designed to withstand fire, flood, wind and other natural disasters better than conventionally built homes," said the company.
It took five to seven days to print each house.
