Building a house by hand can be both time-consuming and expensive.
Some homebuilders have chosen to automate part of the construction instead. A new Ukrainian homebuilding startup called PassivDom uses a 3D printing robot that can print parts for tiny houses.
The machine can print the walls, roof, and floor of PassivDom’s 410-square-foot model in about eight hours. The windows, doors, plumbing, and electrical systems are then added by a human worker. When complete, the homes are autonomous and mobile, meaning they don’t need to connect to external electrical and plumbing systems. To make a PassivDom home, the team maps out the plan for the 3D printer in its factories in Ukraine and California.
Layer by layer, the seven-axel robot prints the roof, floor, and 20-centimeter-thick walls, which are made of carbon fibers, polyurethane, resins, basalt fibers, and fiberglass.
