Dubai has announced plans to 3D print a skyscraper with the help of Cazza Construction Technologies. The company has developed a system of 3D printing buildings at large scale and at high speed with the use of giant robotic 3D printers, and the skyscraper will be printed with the help of cranes that have added units specifically designed for 3D printing at heights of 80 meters and higher. All of the major structural components of the building, including the steel rebar reinforcement, will be 3D printed. It will be the world's first 3D printed skyscraper, and while a start date hasn't been announced yet, the building is part of the Dubai government's plan to have a quarter of the city's buildings 3D printed by 2030.
