Reuters are reporting that Dubai has opened what it said was the world's first functioning 3D-printed office building.
The printers have not been used much for building work; instead focusing on a smaller scale to make digitally designed three-dimensional objects from plastic.
This one used a special mixture of cement and reliability tests were done in Britain and China.
The one-storey prototype building, with floorspace of about 250 m2, used a 20 ft by 120 ft by 40 ft printer.
The arc-shaped office, built in 17 days and costing about US$140 000, will be the temporary headquarters of Dubai Future Foundation.
Dubai's strategy is to have 25% of the buildings in the emirate printed by 2030.
According to research by EC Harris, the UAE's construction industry is enjoying resurgence, driven by major projects such as Expo 2020 and spending on social infrastructure.
