A California couple is set to move into a one-of-a-kind home later this year that will be resistant to wildfires. According to Highways Today, a robotic arm 3D printer created by RIC Technology began construction in January on the state’s first fire-resistant, 3D-printed concrete accessory dwelling unit in the city of Walnut. The general contractor Builtech Construction Group is leading the design in collaboration with the city of Walnut and the Los Angeles County Fire Department.
