If you've ever wondered how comfortable a 3D-printed barrack is, then the U.S. Army is set to find out.<br /><br />The Army recently unveiled a 3D-printed concrete structure known as barrack huts. <br /><br />The structure, otherwise known as "B-Hut," was created by an Army research program. At 512 feet, the 3D printed building is made of locally available material, which is aimed to cut down on labor costs. <br /><br />And they're not done. The lab is working with NASA on a large scale concrete 3D printer that's expected to be done by the end of this year.
