Qatar Installs World's Largest 3D Construction Printer for Pioneering School Project in Doha
Qatar has made a groundbreaking stride in construction technology with the installation of the world’s largest 3D construction printer at a public school construction site in Doha. Manufactured by Denmark-based COBOD International and operated by UCC Holding, the BODXL printer—measuring a massive 50 meters in length, 30 meters in width, and 15 meters in height—was unveiled during a special VIP event.

This state-of-the-art machine, comparable in size to a Boeing 737 hangar, is more than four times larger than any 3D construction printer previously developed. Its deployment comes just 10 months after UCC Holding signed an agreement with COBOD on September 18, 2024, to deliver two next-generation printers for educational infrastructure projects in Qatar.

According to UCC Holding, the BODXL will be used to build two public schools in Doha, each covering an area of 20,000 square meters. Together, they form the largest 3D-printed construction project in the world, totaling 40,000 square meters.

The BODXL has the capability to print structures with a footprint of 1,500 square meters and heights of up to five stories, achieving a total built-up area of 7,500 square meters per structure.

Industry publication VoxelMatters reports that a second printer, identical in dimensions, is already en route to Qatar and is expected to be installed later this month at the same site. Once both machines are operational, they will collaborate to construct what is anticipated to be the world’s largest 3D-printed building—an educational facility commissioned by Qatar’s Public Works Authority, Ashghal.

This dual deployment marks the launch of the largest 3D construction automation initiative globally. It is poised to revolutionize how large-scale public buildings are constructed, combining speed, precision, and sustainability in a way that aligns with the goals of Qatar National Vision 2030.

The project is also expected to be recognized by Guinness World Records as the largest structure ever built using 3D printing technology.

Beyond its record-breaking dimensions, the initiative demonstrates a commitment to sustainable development. Compared to traditional construction methods, 3D printing significantly reduces material waste and lowers the carbon footprint.

COBOD’s third-generation BODXL printers bring a high level of automation and digital precision, allowing for faster completion timelines and better resource management by reducing the need for manual labor and conventional materials.

Henrik Lund-Nielsen, CEO and Founder of COBOD International, praised the collaboration, highlighting it as a landmark achievement in both technological innovation and environmental stewardship. “This partnership with UCC Holding represents a major step forward for the global construction industry,” he said.

UCC Holding echoed the sentiment, expressing pride in leading a transformative project that places Qatar at the forefront of civil engineering innovation. Construction activity using the printers is expected to ramp up significantly throughout 2025.

This project is not just a milestone in school infrastructure—it serves as a launchpad for a future where large-scale buildings can be constructed faster, more affordably, and with greater environmental responsibility through advanced 3D printing.
