Since 2015, scientists and engineers at the U.S. Army Corps of Engineers (USACE), Engineer Research and Development Center (ERDC), Construction Engineer Research Laboratory (CERL) have been exploring expeditionary additive construction technology, also known as construction scale 3D printing.
The first research project, Automated Construction of Expeditionary Structures (ACES), has since developed into the Additive Construction (AC) program. The program focuses on a wide range of technological developments, including printers, deployment exercises, printable concrete materials, functional construction and reinforcement practices, materials testing methods and structural testing.
