Vapor barrier? No Rebar? Concrete has a low R value. Hanging cabinets will suck as will interior doors. What about floor and ceiling molding?
It’s not the same concrete you’re used to. It is engineered to do a lot of things at once - including the perfect viscosity to print from a nozzle and settle just right.
It is it’s own vapor barrier. It’s non pourous. When you print a 2” line of concrete, then give it 5” of air gap, then another 2” line of concrete, that’s the r value. You know stainless steel has a poor r value right? How does a yeti cup work?
Interior doors, you tie your jamb level into side of wall with a shim space just like you normally would. Not sure why you think that sucks?
Hung cabinets? Sure, you need to set wood blocking/cleats on the wall to attach them to.
You know floor and ceiling moulding aren’t necessary building components and are there to cover up what’s wrong with a house right?

With a vacuum between the stainless layers. Maybe you should look up how a Yeti cup works before using it a nonsensical example of why you think such construction would be effective insulation compared to existing methods.

As someone who worked as a professional finish carpenter and has set more doors in a year than you have in your life, I'll tell you right now that a raw rough opening that looks like those walls would be shite to work with. I'd frame them in or taking a demo saw to cut good flat surfaces to work with first. That doesn't get into casing those doors either, I guess you just expect people to live with gaps everywhere...

Crown and base make a home look good. Same as window and door casing. Are you serious?

Dirt and mold will have that thing looking like crap in a couple years. With that rough textured exterior, it's a magnet for crap to get into.

Aren’t these built (printed) on site? Prefab is built elsewhere and moved on site. So no, not the newest way to say “prefab.”

Nonporous concrete? So this is the concrete we make basement walls out of now days? What ingredient is added to make it nonporous?
2" concrete would break so easy especially without rebar or mesh. Unless of course somebody created magic concrete and if they did, can they please share with Louisiana DOTD.
Your Yeti works because of vacuum. My grand pa's old house had a 5" space between the outer and inner wall too.

Those look like every new house in Austin. My kid could design better looking houses on Minecraft.

Probably.
There are only so many shapes you can fit into spaces, and given the shape of furniture which is dictated by the human body those spaces are generally rectangular or square the cookie cutter nature of homes I’d see as more pronounced with 3D printing.
But if it’s cheaper a lot of people will go with it.
Bet you DR Horton will be doing it the second they think it’s viable

I'm really interested in this field. I would like to see one in person though until I can make an informed opinion about it. It's a house, not an app I can download.

While there are tons of uninsulated masonry homes in Europe that are hundreds of years old, I would be interested to see what they use to control vapor drive in this wall system in the gulf coast with the a/c set to 68 deg F in the summer.
I also assume it is some sort of fiber reinforced concrete.
I know this is an ultra modern show house likely requiring all sorts of details, but the 5 month finish out isn't exactly a selling point...tell you what, when they can 3d print me a 10,000 sq ft French Mas or Spanish masia (the OG bardominiums) for dirt cheap, I'll be interested.

You are 3d printing concrete...so I would imagine it would do better than wood frame houses.
Here is a video from 2020 where they were 3d printing hurricane and tornado resistant houses.
ETA
This video claims to have a 3d printed house withstanding an 8.0 earthquake simulation.

My lord. Nonsensical huh? It’s air dumbass. The answer is air. Air gaps can create insulation. Layer - air - layer. Yeti cup and this wall assembly have that in common.
And Mr Finish Carpenter, sounds like you should stick to the shite you do because they wouldn’t want you anywhere near this house anyway.
Go visit the house, find me the gaps everywhere. Oh wait? You’ve never been? You don’t know anything about this construction method? Great, glad we are arguing.

We talking about 3/4” wood lap siding, 2x4 wood studs and 1/2” wood boards versus 2” engineered cured poured product, 5” gap and 2” engineered cured pour product.
I get what you’re saying but can we admit maybe it’s not the same?
We’ve been out to marine bases in Cali and printed it in Johnson space center hangars in Houston, you think it’s like your pappies childhood home?

Looks like a great place for a hornets nest.
