Bringing innovation to fruition: Marines 3D print 1st reinforced concrete bridge in western hemisphere - A Marine with 1st Marine Logistics Group walks across a concrete footbridge during a 3D concrete printing exercise Dec. 12, at Camp Pendleton, California. Working with Marine Corps Systems Command’s Advanced Manufacturing Operations Cell and the Army Corps of Engineers, the 1st MLG used the Automated Construction of Expeditionary Structures—or ACES—printer to conduct 3D concrete printing of the bridge and evaluate emerging technology for future application in Marine Corps engineering operations.
