Guwahati, Dec 6 : The Indian Army has operationalised on-site 3D concrete printing technology in forward areas, marking a major step in enhancing rapid infrastructure development along high-altitude borders.
The capability, developed jointly with IIT Hyderabad under Project PRABAL, has now been deployed by the Trishakti Corps in Sikkim and adjoining locations.
According to an official press release issued by Defence PRO, the indigenous robotic printer is designed for quick, vehicle-portable movement in mountainous terrain and enables rapid construction of bunkers, sentry posts and protective structures.
The printer is equipped with a robotic arm, circular mixer, piston pump and generator.
The structures printed using the system have undergone live ballistic trials, which “validated their strength and protective performance,” the release stated.
The Army noted that 3D concrete printing offers several operational advantages, including customised, terrain-specific designs, enhanced blast and ballistic resistance, higher compressive strength, improved quality control, efficient use of local materials and rapid construction within tactically acceptable timelines.
“The continued adoption of on-site 3D printing represents a significant leap in the Army’s engineering and operational readiness,” said the release, adding that the technology supports sustainable and mission-oriented infrastructure creation in challenging terrain.
