what we really need is to bring back mail-order homes with blueprints and everything, like the historical Aladdin Company or the ones in Sears catalogs

Trade unions have historically disliked prefab, but i think 3d printing is changing their minds

My thought about 3D printing is insulation. The material being 3D printed doesn’t seem like it’ll insulate a house enough.

I think the biggest problem is it takes away from the actual advantages of concrete housing. If these were made with insulated concrete reinforced with rebar, not only would it cost less to build than both a 3d printed house or a traditional wood home, but they'd likely last for over a hundred years.

The material insulates fine but the lack of metal reinforcement and the material being a form of concrete makes me believe that these houses won't/don't last very long

What about that robot that lays concrete blocks, and then fills voids with foam?

The foam isn't what saves it, it just serves as insulation. You still need metal framing and as far as I'm aware they do not have a robot that lays concrete and embeds a metal frame in there.

They seem really hard to repair because you’d have to disassemble the whole house to get a 3-D printer there And a lot of the tech is proprietary so you can’t just hire any home contractor, there’s no “oh I dabble in 3d printed houses”

Only the walls are cheaper. It still costs the same amount or more to get plumbing, electricity, finishing. Site prep can be more expensive since it has to be 100% flat, can’t have a 3d printer at an angle or whatever

What's worse is the material is proprietary, there is literally no way to source repairs without paying off the company who originally 3d printed it. Planned obsolescence at its finest.

What I don't understand is why someone would pay more to have this than a normally fabricated concrete house, something proven to withstand extreme environments with little maintenance for decades

I do think the upfront cost is cheaper for a 3d printed house, esp if you want your house made of concrete since most American houses are cardboard

Not necessarily, 3d printing might be cheaper for the framing but masons tend to make up for that by having more fleshed out and time proven designs that are ready to be hooked up to water, electrical, gas, etc. Normal concrete fabrication, when done properly, also may not even need additional layers of material as protective coating or inner walls, which saves more money on the finish. Both however are advantageous over wood homes.
