Located in the Dubai Municipality, 3D printing construction company Apis Cor completed the all structures of a two-storey administrative building, which is currently the largest 3D printed building.

At 9.5 metres (31 feet) tall and a surface area of 640 square metres (6888 square feet), the building is bigger than Apis Cor’s 3D printer’s stationary reach. However, the printer used is mobile and was moved around the construction site by crane.

The process took place on site in an uncovered area, with uncontrolled environmental requirements like temperature and humidity. The building was printed in one piece, without any extra assembling work. They used a gypsum-based mixture especially developed by Apis Cor themselves. The formwork for columns was manually filled with rebar and heavy concrete.

“The project gave us unique knowledge and invaluable experience that will help us improve our technology and develop a new version of our 3D printer,” Nikita Cheniuntai, CEO and Founder of Apis Cor, says. “The improved version will be more reliable and time efficient (twice as fast). Moreover, during the project we tested and improved our own-developed 3D mixture. This project is a huge step forward in the concrete 3D printing industry.”
