Future Of Homebuilding: “Mighty Buildings” 3D-Printed Prefab ADU’s (2020)

From an Oakland warehouse, startup company Mighty Buildings constructs prefab homes with their Big-G Printer, a 20-foot-tall 3D printer that, at speeds of 120 millimeters per second, can print a 350-square-foot studio in less than 24 hours. The homes are made of Light Stone, a thermoset composite material that hardens when exposed to UV light.

Instead of 3D printing sections of each home for on-site assembly, the machine maximizes cost savings by printing the home’s entire structural shell—thus automating the building process by up to 80% with cost savings of 20% to 30% compared to traditional prefab methods.
