In doing so, the teams, which also includes the 7th Engineer Support Battalion (ESB), tested a new continuous mixer and a three-inch print nozzle to additively manufacture multiple structures, such as barracks and a bridge. 

“This is really the first time we’ve ever printed something large with this system. It is experimental right now and we are trying to push the technology forward,” stated Megan Kreiger, project lead for the Automated Construction of Expeditionary Structures (ACES) at CERL.
