Qatar has embarked on a groundbreaking venture in the realm of construction by initiating the world’s largest 3D-printed building project. This ambitious endeavor, spearheaded by UCC Holding in partnership with Qatar’s Public Works Authority, Ashghal, involves the creation of two monumental public schools using cutting-edge technology developed by COBOD.
The project marks a significant milestone as it pushes the boundaries of traditional construction methods. The schools, each spanning an impressive 20,000 square meters, stand as a testament to the innovative potential of 3D printing in the realm of architecture and design. This initiative is part of a broader strategy to establish 14 educational facilities across Qatar, encompassing a total area of 40,000 square meters.
COBOD’s revolutionary technology has enabled the realization of these colossal structures on an unprecedented scale. In the past, the largest 3D-printed building was a 900 square meter equestrian center in Florida, underscoring the versatility and resilience of 3D printing in the construction sector.
Qatar’s undertaking far surpasses this previous record, with UCC Holding commissioning two custom-built COBOD BODXL printers to bring their vision to life. These mammoth printers, measuring 50 meters in length, 30 meters in width, and 15 meters in height, are a marvel of engineering, akin in size to aircraft hangars.
The design of the schools is a nod to Qatar’s unique landscape, with curvilinear and organic forms that echo the undulating dunes of the desert. The construction process involves the precise layering of a cement-based mixture by robotically controlled nozzles, a technique that allows for the creation of intricate shapes that would be challenging to achieve using conventional methods.
To optimize efficiency and sustainability, much of the construction work is conducted during the night to mitigate the scorching daytime temperatures in Qatar. This approach not only enhances material performance but also aligns with the country’s commitment to reducing environmental impact and energy consumption in the construction sector.
Leading up to the commencement of the project, the team dedicated significant time and effort to preparation and testing. Over the course of eight months, architects, engineers, and materials specialists collaborated to refine the construction process, conducting over 100 full-scale test prints to ensure precision and quality.
Moreover, in a bid to foster local expertise in digital construction methods, the project team underwent intensive training with COBOD engineers in May 2025. This initiative not only enhances the skill set within Qatar’s workforce but also paves the way for future advancements in the country’s construction industry.
Upon completion, these 3D-printed schools will serve as educational institutions, showcasing the practical application and potential of large-scale 3D printing within Qatar’s construction landscape. The project stands as a testament to the power of innovation and collaboration in pushing the boundaries of traditional construction practices.
