Robots have built a big house in Switzerland using 3D-printed materials. It is the first house made by robots for people to live in. It is more environmentally friendly and safer than man-made houses.
The creators say the big house will inspire the future of building. “This is a new way seeing architecture（建筑）,” said one of the creators. "How you build is important."
The big house was built completely from robot-made materials. It used 60% less cement（水泥）than a man-made house. Its ceilings（天花板）were made with a 3D printer. There are 35 parts in the house and each one was built in 60 to 90 minutes. It means that the robots built the full house in just 48 hours.
It is not the first time for robots to build houses. The Chinese used 3D printers to build 10 houses in a day in 2014. They created a building the next year. And last year Italians built a house in just 48 hours.
Scientists say one day they could send robots to build houses on the moon. We are curious about how we're building for the future.
