In a major boost to India’s defence infrastructure, over 500 impact- and blast-resistant 3D-printed bunkers have been delivered to the Indian Army by MiCoB Private Limited, a start-up specialising in rapid and sustainable 3D concrete printing (3DCP) technology.
These bunkers, also called Permanent Defences (PDs), represent a leap in battlefield engineering, combining speed, strength, and sustainability. Designed in close coordination with the Indian Army to meet the requirements of the units that are deployed in extreme environments, these structures are built to withstand high-calibre weapon impact, harsh weather conditions, and extreme temperatures, while offering greater comfort and protection to soldiers.

Unlike conventional bunkers that can take more than a month to build, MiCoB’s automated 3D printing process reduces construction time from 45 days to less than seven days, the company said in a release. This would mean that these bunkers can be deployed rapidly in high-risk areas, a key operational advantage during border tensions or emergencies.
The company’s prototypes were first tested at Pokhran in 2022, where the 3D-printed structures successfully withstood direct hits from a T-90 main battle tank, one of the Indian Army’s most powerful armoured platforms. Trials across various terrains across the country— from icy heights to desert outposts — validated the durability and performance of these 3D-printed bunkers under real-world conditions.
“Delivering more than 500 bunkers to the Army is not just a technological milestone — it’s a demonstration of how innovation meets purpose,” said Shashank Shekhar, co-founder and CEO of MiCoB, adding “Each structure is designed to enhance safety, comfort, and readiness in the most challenging terrains.”
