Indian Railways Showcases First 3D-Printed Gangman Hut in Andhra Pradesh – Built in Just 25 Days!
Andhra Pradesh, India – In a groundbreaking move towards sustainable infrastructure, Indian Railways has successfully constructed India’s first 3D-printed gangman hut at the Parvatipuram railway station in Manyam district, Andhra Pradesh. The innovative structure, spanning 100 square metres, was built in a record 25 days, showcasing the potential of 3D printing technology in revolutionizing construction.
A Milestone in Railway Infrastructure
The 3D-printed gangman hut, developed under the Waltair division of the East Coast Railway zone, is designed to provide shelter, rest space, tool storage, and a work base for track maintenance staff (gangmen). This project, executed by Rail Vikas Nigam Limited (RVNL), marks the first-ever 3D-printed railway building in both Indian Railways and Andhra Pradesh.
How Was It Built?
The hut was constructed using a 3D concrete printer, a robotic system that builds structures layer by layer. Unlike traditional 3D printers that use plastics or metals, this technology employs ultra-high-performance concrete (UHPC) and lightweight concrete, ensuring durability, strength, and resistance to harsh weather conditions.
RVNL highlighted that 3D printing allows for complex designs, textured elevations, and intricate wall patterns that are difficult and time-consuming with conventional methods. Additionally, this approach reduces material waste and construction time, aligning with the government’s PM Gati Shakti and Green India Mission.
Boosting Connectivity & Future Prospects
The new railway line near the Parvatipuram station is expected to enhance freight and passenger capacity, particularly with rising industrial activity in the region. RVNL emphasized that this project could pave the way for more 3D-printed, low-cost, quick-build infrastructure across India, making construction faster, eco-friendly, and cost-effective.
Key Benefits of 3D-Printed Construction:
✔ 25-day construction time (significantly faster than traditional methods)
✔ Reduced material waste (eco-friendly approach)
✔ Superior durability (UHPC ensures long-lasting structures)
✔ Cost-effective & scalable for future projects
This cutting-edge initiative by Indian Railways sets a new benchmark in infrastructure development, demonstrating how technology can drive sustainability and efficiency in public projects.
