I was going to ask, How do they print re-bar?

But then I saw the line about 8-foot thick walls, and thought that maybe they really didn’t need re-bar. But then the fifth photo in the article shows a forest of re-bar, clearly not “printed”.

In the photos there’s no evidence of 8-foot thick walls, so I’m thinking that “8 inches” got lost in the translation. From the pictures, it seems like the printing method is to lay down 8-inch wide, 2-3 inch thick layers of wet concrete along the perimeter of the house. It took 45 days because each layer had to cure before the next one could be laid down. The “printer” would be like a big pastry bag controlled by a robotic crane.

B the time it got back around finishing a layer it may have been cured.

Will all the house wiring conduit and boxes and pipes be visible since the walls are solid?

This whole story, like so much from him, is a bunch of hokum.

3D printing involves building layers fused by a laser. Anything from metal to human tissue can be fused this way.

Concrete can be layered by computer control, but it's not "printing," it's just automation.
