The world's tallest 3D-printed building has recently been completed in the Saudi Arabian capital of Riyadh. The three-story villa is 9.90 m high and offers an area of 345 sqm.
The building was produced by Saudi Arabian real estate developer Dar Al Arkan using a Cobod 3D printer. Low-cost local materials were used to produce the 3D printable concrete.
The villa was 3D printed in just 26 days and fully complies with building codes, according to Cobod. This, he said, makes the house an example of how "technology and innovation can go hand in hand with safety and regulations." Heat-reflective nanotechnology was used to paint the exterior walls, making the villa up to 40% more heat resistant, he said.

Using advanced 3D printing technology, Dar Al Arkan aims to provide its customers with a customized experience, building homes tailored to their unique tastes and preferences. "The introduction of 3D construction printing enables us to focus on greater flexibility of design, strengthen productivity and achieve higher cost efficiency,” said Wael al Hagan, 3D construction printing project manager from Dar Al Arkan. Saudi Arabia is open to the use of advanced construction technologies as the kingdom aims to enable 70 percent of the Saudi population to own their own homes by 2030.
The villa in Riyadh was built using local materials and the D.fab solution developed by Cemex and Cobod. This enables 99% local and cost-effective materials to be used, while only 1% is sourced from a central location.
