Qatar Begins Construction of the World’s Largest 3D-Printed Schools

Doha, Qatar - September 6, 2025 - Qatar has launched a groundbreaking project to build the world’s largest 3D-printed structures, two futuristic public schools that will redefine global construction standards. Each school will span 20,000 m², for a combined total of 40,000 m², making them nearly 40 times larger than the biggest 3D-printed building constructed to date.

At the heart of this mega-project is UCC Holding, working in partnership with Ashghal, Qatar’s Public Works Authority. The team has joined forces with COBOD International, a leading Danish firm specializing in large-scale 3D-printing technology. Together, they are bringing a bold concept to life with two of the largest 3D printers ever built, known as BODXL printers.

Each BODXL printer measures approximately 50 meters long, 30 meters wide, and 15 meters high — comparable to the size of a Boeing 737 hangar. A single printer can build on a 1,500 m² footprint, reaching up to five stories and 7,500 m² of built space. With both printers operating simultaneously, the project team can efficiently deliver the full 40,000 m² footprint of the two schools.

Eight Months of Preparation and Testing

Before construction began, the team spent eight months testing the technology at a dedicated trial site in Doha. Over 100 full-scale test prints were completed to refine custom concrete mixes, perfect nozzle designs, and ensure reliable performance in Qatar’s challenging desert climate.

Sustainability and Efficiency at the Core

3D printing significantly reduces material usage and construction waste, cutting overall costs and minimizing environmental impact. Printing takes place mostly at night to avoid Qatar’s intense daytime heat, improving energy efficiency and creating safer working conditions for crews.

Timeline and Future Development

The two schools are part of a broader plan to construct 14 new schools, all scheduled for completion by the end of 2025. Additional project details, including timelines for the remaining schools, will be announced in the coming months.

Design Inspired by Nature

Architecturally, the schools will feature organic, flowing forms inspired by Qatar’s desert landscapes. The advanced layered printing technique makes it possible to create curved, dune-like walls, a design feat nearly impossible to achieve with traditional construction methods.

This landmark project represents a major leap forward in sustainable construction, positioning Qatar as a global leader in 3D-printing technology and innovative infrastructure development.
