Doha, Qatar — The world’s largest 3D construction printer, the BODXL by COBOD International, has been installed at a school construction site in Doha. Measuring 50m x 30m x 15m—comparable to a Boeing 737 hangar—the printer is over four times larger than the previous largest 3D construction printer.
Installed by UCC Holding less than 10 months after signing a contract with COBOD, the BODXL will be used to build two public schools spanning a combined 40,000 square meters, marking the largest 3D printed construction project globally to date.
The BODXL can print building footprints of up to 1,500 square meters and structures as tall as five floors, creating up to 7,500 square meters per printer. A second identical printer is expected to be installed at the site shortly, enabling both to work together to construct the world’s largest 3D printed building—a multi-thousand square meter educational facility commissioned by Qatar’s Public Works Authority, Ashghal.
This project sets a new benchmark in construction speed, sustainability, and precision, with expectations to earn a Guinness World Record for the largest 3D printed edifice.
Aligned with Qatar National Vision 2030, the initiative reduces material waste and carbon footprint compared to traditional construction. The third-generation BODXL printers deliver high automation and digital accuracy, minimizing manual labor and boosting resource efficiency.
COBOD CEO Henrik Lund-Nielsen hailed the collaboration as a technological and environmental milestone, emphasizing its potential to revolutionize sustainable construction worldwide. UCC Holding leaders echoed this pride, positioning Qatar as a leader in innovative civil engineering.
Construction is slated to accelerate in 2025, with the school serving as a pilot for future large-scale 3D printed buildings that promise faster, more cost-effective, and eco-friendly construction methods. The printers will operate at maximum speed while maintaining stringent safety and sustainability standards.
