IIT-H and Simpliforge Develope Prototype Bridge with 3D Concrete Printing Technology

06 April 2023: 3D printed bridge has been developed and printed with collaborative efforts of Indian Institute of Technology, Hyderabad (IIT-H) and Simpliforge Creations. The bridge was designed, developed and evaluated by IIT-H Civil Engineering Prof. K. V. L. Subramaniam and his research team. The bridge was printed by Simpliforge, a startup company specialising in providing 3D concrete printing solutions.

The bridge has been designed at IIT-H with minimum use of concrete and reinforcement. It was developed on the concept of ‘Material follows Force’. Simpliforge Creations developed an extrusion and software system specifically for the project to fully exhibit merits of their 3D printing system. Using the Industrial robotic arm 3D printer, the bridge was printed off-site in little under two hours at Simpliforge Printing facility and assembled on site at Charvitha Meadows, Siddipet, Telangana.

Enlisting the uniqueness of 3D printing technology, Prof. Subramaniam said, “3D concrete printing is an emerging technology has the potential for transforming the construction industry with the promise of rapid, efficient and free-form construction. Technology application in this space requires advancements in design methodologies, material processing, and delivery systems.”

“We are proud to have been a part of this ground-breaking project” said MD of Simpliforge Hari Krishna Jeedipalli, adding “This bridge is a testament to capabilities of 3D construction printing technology and its potential applications in infrastructural requirements, defence, and disaster scenarios owing to its speed and ease. We hope that this project will inspire others to explore possibilities of 3D concrete printing in infrastructure and other industries.”
