MiCoB Delivers 500+ 3D-Printed Bunkers to Indian Army, Slashing Build Times to Under Seven Days

India – MiCoB has delivered more than 500 3D-printed permanent defences (PDs) to the Indian Army, supporting the expansion of India’s defence infrastructure with faster construction and sustainable materials, the company said. The 3D-printed bunkers are designed for deployment across high-altitude, snow-covered, and desert terrains, with protection and insulation features tailored to military requirements.

Delivery Focused on Speed, Protection, and Sustainability

MiCoB said the delivery is part of a broader push to modernize defence infrastructure using 3D concrete printing and automated construction systems. The company emphasized that its proprietary designs and materials enable rapid deployment while maintaining quality and safety standards.

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.”

Rapid Construction and Efficiency Gains

According to MiCoB, the use of automated 3D printing shortened the typical construction time for each bunker from about 45 days to under seven days. This accelerated timeline is intended to facilitate quick installation in priority locations without compromising on durability or safety.

The company reported major material savings compared with traditional construction methods. 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.”

Capabilities and Deployment

MiCoB stated that each bunker is engineered to meet the operational needs of Indian Army personnel working in severe environmental conditions. The PDs provide ballistic protection in line with military standards and include thermal insulation to support troop safety and comfort in extreme climates.

Deployment spans varied geographies across India, including high-altitude mountains, snow-bound regions, and desert sand dunes. The company said its design approach integrates on-ground realities to enhance operational readiness, aiming to support sustained deployment in remote and challenging areas.

Field Testing and Trials

Field testing of MiCoB’s 3D-printed bunkers began in Pokharan in 2022, according to the company. The structures underwent weapon trials and have passed multiple tests across different geographic and climatic environments, MiCoB said, underscoring their suitability for operational use.
