My guess from painful experience is that you are an employee of a local building department.
Steel cables and steel meshes provide very effective reinforcement in “printed” concrete structures. They are either laid down in between layers or extruded simultaneously with the concrete depending on the type of machinery being used. Do you think that the engineers and others who are working on this new method of construction believe that they are not going to be required to demonstrate that the structures formed are not both strong and safe?
Is this a method that will be able to be used or useful for every project? Obviously not! But is it something that should be rejected based on some sort of ignorant preconceived notions?
It is people like you who are a big problem when it comes to creating affordable safe housing in the United States. You make assumptions and will not make any effort at all before spouting out nonsense.

Not quite; I’m a retired Horticulturalist/Botanist of 53yrs experience. I’m a big supporter of innovative housing techniques, but this looks it is fraught with future problems.
Please, prove me wrong.
I’ve rerun the video several times, and can’t see any structural support for the multi-layer concrete extrusion. If there is support, I’ll be surprised and support that process wholeheartedly. As is, I can see none and would think that even a mild earthquake in the 4-5 range, or 65-80mph wind might cause the structure some deadly problems.
