Under the proposals, announced in detail at the North American Annual Symposium for Construction (NAASC), fleets of hundreds of autonomous 3D printing robots will build the 20 metre-high, 1000 mile long wall in-situ, at an expected rate of around 10 metres per day.
Featuring specially developed multi-material printing heads, the robots - jointly developed by a US/Russian consortium - are able to simultaneously deposit liquid concrete as well as the wall’s metallic supporting structures (expected to made from a gold alloy).
The systems will use solar panels to harvest energy from the sun providing enough electricity to fuel them throughout the day and to charge batteries to enable 24-hour operation. It’s envisaged that the devices will serviced by autonomous flying drones that will deliver the feedstock for the 3D printing systems.
Once construction of the site is complete the devices will be equipped with motion sensors and machine guns and repurposed as border guards.
The heavy levels of automation at the site have angered many, who have accused the Trump regime of failing to deliver on an election promise to create thousands of new construction jobs.
Meanwhile, Department spokesman Sean Kwef dismissed claims that the technology doesn’t exist, accusing detractors of disseminating “fake news” and insisted that work on the project could begin as soon as the end of the month.
