Post Marines 3D-print concrete barracks in just 40 hours

Marines have used a specialized 3D concrete printer to print a 500-square-foot barracks room in just 40 hours.

The innovative project created the world’s first continuous 3D-printed concrete barracks, according to the Marine Corps.

The barracks room was built earlier this month at the U.S. Army Engineer Research and Development Center in Champaign, Ill. Army and Navy Seabees were also involved in the construction effort.

Harnessing the world’s largest concrete printer, the Additive Manufacturing Team at Marine Corps Systems Command teamed up with Marines from I Marine Expeditionary Force.

“This exercise had never been done before,” said Capt. Matthew Friedell, Additive Manufacturing project officer in MCSC’s Operations and Programs/G-3, in a statement. “People have printed buildings and large structures, but they haven’t done it onsite and all at once. This is the first-in-the-world, onsite continuous concrete print.”

Using Computer Aided Design software on a 10-year-old computer, the concrete was pushed through a print head and layered repeatedly to build the barracks room walls. Friedell said that the job took 40 hours because Marines were carefully monitoring the project and continually filling the printer with concrete. However, if a robot was used to do the mixing and pumping, the building could be built in 24 hours, he added.

I can just picture an older Marine replying to this with a "back in my day..."
Normally, it takes 10 Marines five days to construct a barracks hut out of wood.

And they had to move the wood uphill both ways...

The story is impressive, but I don't know how much of a NEED for this...and I hope this was a lowcost exercise instead of a million-dollar waste...

it would have taken a private company 80 hours due to cost plus

I wonder how long it took to set all that up so that the 3d printer can do that?

I'm not a Marine, I'm a dogface. We could put up the tent in about 15 minutes and dig a safe fox hole in about an hour. I think I'd prefer the concrete barracks. Maybe do my first two days in the tent, then upgrade to the solid walls and more room.
