PROJECT PRABAL

Overview

• India’s first on-site 3D-printed military bunker built in Leh (11,000 ft altitude).
• Developed by Simpliforge Creations in collaboration with IIT Hyderabad.
• World’s first military-use 3D printed bunker constructed at high altitude.

Key Features

• Project Name: PRABAL (meaning “strong”).
• Construction Time: Less than 2 weeks including transportation.
• Built under HALO conditions – High Altitude, Low Oxygen.
• Located in a highly inhospitable terrain (40–50% oxygen level).
• Custom 3D concrete mix developed for high-altitude conditions.

Technical Highlights

• 3D printing allowed:
  • Quick deployment.
  • Tailor-made configurations.
  • Special geometric façade to minimize bullet ricochet (undulated surface).
• Enables 5–6 days rapid bunker production post-prototype.

Significance

• First-of-its-kind indigenous defence infrastructure solution.
• Promotes Atmanirbhar Bharat in defence sector.
• Example of academic-industry-defence collaboration.
• Demonstrates rapid deployability, innovation under extreme conditions, and tech-driven security.
