China’s first buildings made with 3D printing installed Shanghai

The video shows some rebar laid down between some of the layers.  I imagine plumbing and conduit can be laid in during the print.  More likely though you would just expect to keep that to interior walls.  I imagine it would be similar to when houses are built with concrete block.

I would guess that it is similar to block construction also.  I am wondering how they get vertical rebar in there as it is code in this state.  That is unless you have some structural testing to prove it isn't needed.  Being in the middle of building my third home and doing most of it myself makes this very intriguing.  Plumbing and conduit could also be run in the middle with a little drilling also.

A few of the pictures do show some rebar.

I'm not seeing it.  I guess I'll have to take a road trip one of these days.

People from Minnesota must be crazy!!!
The concept is awesome but concrete without some kind of reinforcement like rebar is not really that strong.

+1

On top of that, the first few images show signs of significant moire.
