A research team at the University of Nevada, Reno is working on an innovative approach to efficiently provide military infrastructure in conflict zones. In collaboration with the U.S. Army Engineer Research and Development Center, the team, led by Prof. Floriana Petrone and Prof. Sherif Elfass, is developing a method to create modular structures using 3D printing. The project is funded by the U.S. Department of Defense and is expected to be completed by June 2025.
The focus is on concrete modules shaped like “LEGO-like” segments, manufactured through 3D printing. These modules enable the construction of bridges or buildings that can be assembled on-site as needed and later dismantled. A recently conducted load test in a large-scale laboratory demonstrated that a test bridge consisting of seven modules could support up to 3,000 kilograms. Data from this and other tests are being incorporated into numerical simulations to analyze the structural integrity and load capacity of such constructions. “We are following a structured approach,” Petrone said, “introducing rigor in the way we approach the printing.”
A key advantage of this approach is the ability to connect the modules using simple cable systems that can be installed without specialized equipment. This is particularly relevant for use in remote or conflict-affected regions, where traditional building materials or tools are often unavailable. “Everything could be assembled manually on site,” Petrone said about the cabling system, because specialized equipment may not be available in a combat zone.
The combination of 3D printing, segmental construction, and numerical modeling provides a promising foundation for developing scalable and robust infrastructure.
“The integration of numerical modeling with 3D printing and segmental construction provides a powerful tool for predicting structural performance before construction even begins,” Elfass wrote. “This allows engineers to optimize the placement of segments and the design of printed components, ensuring that printed structures meet the necessary strength and durability requirements in a variety of conditions.”
The project demonstrates how modern technologies can contribute to enhancing the flexibility and efficiency of military operations.
