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.

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.

The construction industry is keen to tap into the power of 3D-printing. Last year, for example, experts at Eindhoven University of Technology in the Netherlands produced the world’s first 3D-printed reinforced, pre-stressed concrete bridge. The cycle bridge is part of a new road around the village of Gemert in southern Holland.
One of the big advantages of 3D-printed concrete is that much less concrete is needed compared to the traditional technique of filling a mold with concrete, according to experts from Eindhoven University of Technology.

Could this be used for sections of the border wall?
Saw a video of a robot building a cinder block wall and mortaring the joints a few months ago. Pretty cool.
>>Could this be used for sections of the border wall?<<
Could this be used to help the homeless?
A heck of a lot less than the endless $$$ they throw at the problem.
Oh, militarized 3-D printing.
“Could this be used to help the homeless?”
No. They are not homeless because they don’t have a home.
Bttt.
5.56mm
then they blew it up real good.
give me 10 mexicans and some concrete forms and I’ll have it done in a day
My first thought as well.
I don’t know what final design will be picked for the wall, but what they are putting up now in replace and repair sections is only concrete on the bottom, mostly underground. What is above ground is metal sections attached to the concrete, the reason for this is Border Patrol requested a see through fence so they could see what is going on behind the wall. The metal sections go up fast though- if the bottom part could be 3D printed it might work great.
WOW!!!! That is cool. I’d like to watch this process. I’ll hazard a guess the you can’t get the Printer at Wally*World ?
Interesting.
Construction is about to undergo a revolution. So is agriculture with robots doing a lot of work farmers used to do like seeding and harvesting.
I have been waiting for this for a long time. The possibilities are enormous.
This might be an area for investment...:)
Ooh, a 500 sq. foot. ‘barracks.’ Must be for enlisted personnel.
Does the 40 hours include setting up and taking the 3D printer? And how quickly could some slip forms for the same sized structure be set up?
Gee whiz for the sake of gee whiz.
