Oman is advancing its construction sector through the adoption and localisation of 3D printing technologies, aiming to cut costs, reduce emissions, and modernise building practices as part of its broader economic transformation.
The Sultanate is forging a partnership between academic research institutions and private industry to embed automation and additive manufacturing within mainstream construction. At the Green Build Oman forum, Dr. Muhammad Bilal Waris, Associate Professor at Sultan Qaboos University (SQU), articulated how 3D concrete printing represents a strategic enabler for Oman’s Vision 2040 goal of developing a knowledge-based and innovation-driven economy.
Dr. Waris explained that 3D printing for construction involves an extrusion process that precisely places material layer by layer, enabling faster build times, reduced material waste, and expanded architectural freedom compared with traditional methods. However, he emphasised that successful implementation depends critically on tailored material formulations that meet both structural and pumpability requirements.
Central to the research effort is the development of 3D printable concrete mixes using locally available materials, particularly Omani clays and limestone. This approach not only supports sustainability and lower carbon emissions but also strengthens supply-chain resilience by reducing reliance on imported cement. A promising solution explored by researchers is Limestone Calcined Clay Cement (LC3), which can substantially cut carbon emissions while enhancing material performance.
The SQU team has conducted extensive laboratory testing—evaluating hundreds of mix designs and employing advanced analytical techniques to characterise material behaviour. Leveraging machine-learning models, researchers can now predict the performance of concrete mixes based on mineral composition, streamlining the design process for prints across different regions of the country.
Alongside academic work, Omani companies are rapidly translating research into practice. Innotech, a homegrown technology firm, has developed a locally manufactured construction 3D printer that cuts costs by around 60 percent compared with imported machines while proving resilient to local climate conditions. The company has already delivered more than a dozen printed structures, ranging from prayer rooms to public facilities, and is now progressing to larger projects such as mosques, schools, and commercial buildings.
Industry leaders acknowledge that although 3D printing remains marginally more expensive than conventional construction, ongoing research and economies of scale are expected to narrow this gap. The integration of sustainable materials like LC3 and recycled additives further enhances the long-term viability of 3D printed construction for Oman’s built environment.
Together, these academic and industry efforts signal that Oman’s construction sector is moving beyond early experimentation toward a future where advanced automation, sustainability, and local innovation redefine how buildings are designed and constructed.
