MiCoB co-founder and CEO Dr Shashank Shekhar said: “Delivering 500+ 3D Printed Bunkers (3D PDs) to the Indian Army is more than an achievement, it’s a powerful demonstration of how innovation meets purpose to strengthen and protect our nation. Each structure has been thoughtfully designed with a deep understanding of the Army’s on-ground realities, ensuring every feature enhances safety, comfort, and operational readiness, even in the most challenging terrains.
“Collectively, we have delivered more than 650 3D Printed buildings across the nation, which is highest in terms of 3D printed volume globally.”
According to MiCoB , each bunker is designed to match the operational requirements of Indian Army personnel working in locations that experience severe environmental conditions.
These structures are deployed in varied regions such as high-altitude mountains, snow-covered areas, and desert sand dunes.

By GlobalDataThe 3D-printed bunkers, referred to as permanent defences (PDs), offer protection suitable for military needs, thermal insulation, and meet military standards for resistance against ballistic threats.
MiCoB made these bunkers using its proprietary designs, materials suited for 3D concrete printing, and automated construction systems to enable rapid building processes.
With this method, the company was able to shorten the construction period for each bunker from about 45 days to under seven days. This approach allows quick installation in key areas while still meeting quality and safety standards.
Dr Shekhar added: “In the projects delivered by us, we saved over 20,000 tons of construction material compared to conventional methodology, aligning with our motto of building sustainably with speed. This is a proud moment for India as we are leading the innovation and adoption of 3D concrete printing technology, and the active support from various government and private stakeholders will position India as a leader in the sustainable construction practices.”
According to the company, field testing of MiCoB’s 3D Printed Bunkers began in Pokharan in 2022.
The bunkers underwent weapon trials and have passed several tests conducted across different geographic and climatic environments.
