They're not a gimmick, they're dirt cheap to build relative to the quality you get (when you're not a pack of literal community college students using a non-load-bearing material like hempcrete, working on a learning project).
The way it's done drives the cost through the floor, even relative to a modular house, and, let's try thinking about it for a second, if you take a liquid concrete mix and poop it out in a line and cure it properly, how is this different or worse than taking that same liquid concrete mix, dumping it into a mold you built, and then also curing it properly? Because that's (in very simple terms) the basic difference between 3d printing houses and building them.
Basically, it's a lot cheaper (I've seen multi-bedroom houses -- real houses, not haha this is a big shed that you can abuse as a studio if you lie to your county planning department -- printed for under $20k) and when done right, the quality is the same as any other concrete construction. The secret is just like any other construction: you have to do it right!
Right now, they're super rare because there are no standardized building codes available for them, which means planning departments don't have industry-standard guidance they can draw on for their own building codes, so in most places you just can't get them approved.
Like with any technology, there will be a gold rush and tons of idiots doing it wrong or badly to turn a quick buck on the hype, but come on. New technologies are transformative, and additive construction or whatever you want to call it has tons of potential.
Its worth noting, your numbers are super misleading..
the manufactured home cost in the bob vila article includes the entire house (foundations, land clearing, utilities, finishes, permit fees, etc).. aka, for the 270k, youre getting a move-in ready house.
The 3D printed home cost in your builtin article appears to only include the basic structure (aka the cheap part). Still gotta pay teams of people to come on-site to do everything else. The cheapest they mentioned was $299k for a move-in ready house.
Well, I double checked because I've done a fair amount of research and the All3DP article was literally just a random example I found off Google. A realtor interviewed for Yahoo! finance said buyers could expect to pay about $15k-$50k for a starter 3d-printed home. Doesn't sound like I'm actually in the wrong ballpark here. How fancy you make it and where you put it will obviously influence the cost of construction. A 3d printed summer mansion for Bill Gates in the Bay Area isn't going to be $15k, obviously.
