U.S. Army Corps of Engineers tests 3D-printed concrete barracks

A research team within the U.S. Army Corps of Engineers recently 3D-printed full-scale concrete walls in an effort to create quick-to-assemble barracks for field housing, according to Engineering News Record. The project, named Automated Construction of Expeditionary Structures (ACES), aims to engineer structurally efficient and safe concrete barracks with precast roofs and 3D printed walls. In their latest tests, they were able
