Qatar has once again pushed the boundaries of innovation with the installation of the world’s largest 3D construction printer at a public school construction site in Doha. The BODXL printer—sized like a Boeing 737 hangar at 50m x 30m x 15m—is the first of two giant printers developed by Denmark’s COBOD International and operated by UCC Holding.

Unveiled during a recent VIP event, this groundbreaking machine is more than four times larger than any previous 3D construction printer and is set to change the face of building design and implementation.

Less than 10 months after signing the landmark contract on September 18, 2024, UCC Holding and COBOD have successfully installed this next-gen printer, which will be used to construct two public schools in Doha. Each campus will span 20,000 sqm, totalling 40,000 sqm, making this the largest 3D printed construction project ever undertaken.

The BODXL’s capabilities are staggering. It can print structures up to five floors high with a footprint of 1,500 sqm—enabling rapid, precise, and sustainable building processes. A second identical printer is scheduled for installation later this month at the same site, doubling the speed and scale of the project.

According to VoxelMatters, a global additive manufacturing news platform, this dual deployment marks the largest 3D construction automation initiative in the world, with both printers working together to produce a record-breaking educational facility for Qatar’s Public Works Authority, Ashghal.

Beyond the scale and speed, the initiative aligns closely with Qatar National Vision 2030, offering a sustainable alternative to traditional construction by reducing material waste and carbon emissions. The third-generation BODXL introduces high automation and digital precision, reducing manual labour and ensuring faster project delivery.

Henrik Lund-Nielsen, CEO of COBOD International, hailed the partnership with UCC Holding as a technological leap forward, paving the way for a smarter and more eco-friendly construction era. UCC Holding echoed the sentiment, calling the project a proud milestone that places Qatar firmly on the map as a global leader in construction innovation.

Construction activity with the printers will ramp up significantly in 2025, with the schools projected to be the first in a series of large-scale, rapidly constructed, and environmentally conscious buildings in Qatar.
