Epitomizing Expeditionary Construction: Navy 3D Printing Buildings

Last years news, but new to me. All you would need to carry would be the printer and cementitious material of choice. Aggregate could be found locally. Expeditionary construction from contingencies (humanitarian and defensive) to space exploration

"The United States Navy is funding the project on 3D printing buildings. This project, called Contour Crafting, has the purpose of printing out 2,500-square-foot buildings in only one day using concrete. The project could be very useful to armies worldwide, as it gives them the ability to quickly create houses in environments with little or no structure. Another application of Contour Crafting? Providing for shelter on the Moon."
