Marines are applying advances in 3D-printed concrete to military uses ranging from ramps to makeshift railheads, according to the operations chief of the 9th Engineer Support Battalion.
First conceived in the 1930s, 3D concrete printing gained momentum in the 1980s with improvements in technology and materials that allow small teams to build homes, bridges and other structures quickly and at lower costs. “Over the last two decades, 3D concrete printing has established itself as a leading digital fabrication technology in the concrete industry,” said a December 2023 paper published in Science Direct.
