World’s largest 3D-printed building opens in Dubai after 2 weeks of construction

Quickly gaining popularity as an affordable and sustainable way to build, 3D printing is becoming a go-to construction choice for architects around the world. In fact, one Boston-based company, Apis Cor, well-known for its 3D-printed architecture, has just completed construction on the world’s largest 3D printed building. Located in Dubai, the 6,998-square-foot building was completed in just two weeks.

Working under its motto, “we print buildings,” Apis Cor has become a prominent leader in the world of 3D-printed architecture. From a tiny home in Moscow to affordable housing developments in California and Louisiana, its state-of-the-art techniques have been used for various types of projects.

Although the company is accustomed to building in various parts of the world, Dubai‘s harsh conditions put its standard methods of printing to the test. Dubai is known for its severe climate, in which the temperatures rise and drop suddenly. As such, the materials used in the printing process for this particular building had to be able to withstand extreme heat and cold. “The Dubai climate is very harsh — temperature and humidity change significantly even within a day,” said Nikita Cheniuntai, founder and CEO of Apis Cor. “The material has to behave the same way all the time, despite the changing environmental conditions.”

Working on such a large project presented additional challenges. The construction site spanned approximately 7,000 square feet, which, under normal building circumstances, would require assembly of ample scaffolding. However, because the company’s custom, car-sized 3D printer is mobile, the building was constructed directly onsite faster and more efficiently than a traditional construction project.

Along with three workers and a single construction crane, the machine printed out the structure section by section using Apis Cor’s gypsum-based mixture. Later, traditional constructions methods were used to install the windows and roof, and rebar supports were added to reinforce the walls.

The resulting building, which will house administrative offices for the Dubai Municipality, has a white facade that reflects the sun rays. The concrete and gypsum printing materials created by Apis Cor also provide the building with a naturally insulated envelope, keeping the interior at a pleasant temperature year-round.
