Democrats say President Trump’s wall would either be too costly, too laborious, or too complex to complete. And yet, America is now living in the age where Marines at Camp Pendleton can successfully 3D-print a reinforced concrete bridge in just 14 separate hours.
According to Fox News, in December of last year, U.S. Marines assembled the first ever 3D-printed bridge on site in the Western hemisphere. Typically, such bridges are printed in a factory. A Marines spokeswoman told Fox News that construction took 14 separate hours over 3 days with breaks and sleep in between rather than 14 continuous hours.
