US military uses 'world’s largest' 3D printer to build concrete barracks

the US marine corps systems command (MCSC) has constructed a prototype concrete barracks in under two days with what it calls the world’s largest 3D printer. the 3D printer was used to build a basic barracks hut measuring 500 sq ft (46 sq m) in just 40 hours.

 

MCSC’s additive manufacturing team collaborated with I marine expeditionary force to build the prototype barracks at the US army engineer research and development center in champaign, illinois. the team started with a computer-aided design model on a 10-year old computer, concrete and a 3D printer. once they hit print, concrete mixture was extruded through the print head and layered repeatedly to build the walls.

the marine corps is now carrying out more research to see how the technology can be employed in the field and if the construction process can be refined. in their evaluation of the exercise, the team notes that if a robot was uses to do the mixing and pumping, the building could easily be created in one day if using the 3D printer.

in active or simulated combat environments, we don’t want marines out there swinging hammers and holding plywood up,’ says MCSC captain matthew friedell.having a concrete printer that can make buildings on demand is a huge advantage for marines operating down range.’

  • Fast emplacement – ok but debateable. Effectiveness contra fire – doubtful. In 40 hours and a squad you could build from whats on the ground – with a roof. Plus it can be continuously modified. There are not enough covering slits on that thing for effective front line. If ‘bunker’ is semi permanent then make it elsewhere and airlift.

  • That might qualify as the largest 3D printer that prints by creating layers, but Branch Technology in Chattanooga, TN has the world’s largest free-form 3D printer, and it also looks to be bigger than the MCSC’s 3D printer mentioned in this article.
