In 2023, India’s first 3D printed post office spread across 1100 S.Ft was built in 45 days at a cost of 23 lacs. The duration was reduced by approximately 40 percent, whereas the cost was approximately the same as compared to similar-scale construction using traditional techniques, however, this can be made affordable if implemented on a large scale. Furthermore, the Indian government is actively working on establishing a standardized code for 3D-concrete printing, which could further streamline and advance the adoption of this innovative approach in construction.
Beyond its potential for design innovation, 3D printing offers a range of sustainable solutions. Traditional construction is notorious for its inefficiencies—wasted materials, excessive energy use, and environmental degradation. In contrast, 3D printing enables a more controlled use of resources, significantly reducing waste by using only the exact amount of material required for each build.
Additionally, the ability to utilize eco-friendly materials—such as recycled materials and innovative bio-concretes—can further minimize the environmental liability of new structures. The efficiency in material usage also translates to reduced carbon emissions, making 3D printing a promising technology in the pursuit of greener building practices.
As we stand on the brink of a construction revolution, it’s clear that 3D printing will play a critical role in shaping the future of the built environment. Industry leaders are already taking notice. For example, Godrej, a pioneer in Indian construction technology, recently completed a successful project in Pune using 3D printing techniques, proving the technology’s viability on a commercial scale.
It’s only a matter of time before we see entire neighbourhoods or gated communities “printed” into existence. The idea of on-demand, customizable printing of a structure is no longer construction fiction—it’s an achievable goal. As this technology will evolve more, it holds the potential to not only redefine construction practices but also reshape our ideas on the extent of its applications in real time construction, architecture and engineering.
