Are 3D-printed homes the future of home construction?

Austin, Texas-based 3D printing construction company Icon unveiled its new 2,000-square-foot home, House Zero.

I spent a night inside of a luxury 3D-printed home and now I'm convinced the technology has a place in the future of home construction.



In early March, 3D printing home construction company Icon unveiled House Zero, an over 2,000-square-foot 3D printed home in Austin, Texas.



The walls of the main home and its accessory dwelling unit were printed at the same time in eight days despite weather and hardware issues.



The team then spent five additional months finishing the rest of the home, like window installation, wiring, and plumbing.

It they can produce a durable, well built product that in comparable in price then sure.

Probably not any worse than whatever D.R. Horton and Taylor Morrison are building these days.

It’s just the newest way to say “prefab homes”.

How does it do against a nado?

I’m down for it if people want it. I’m failing to see the benefit though. Are resin-based home materials cheaper than lumber? Are you not still going to have to pay labor to put it together? Perhaps there’s a cost-reduction angle here other than during periods of tight supply constraints (which may come and go).

(Democratizing housing design by making the blueprints easily editable in CAD might be a fun avenue for homeowners who want to personalize their housing design on the fly.)

I don’t feel like my chances against a tornado would be good in a 3D printed home.

Cool that technology can do that, though.

From what I've read, this technology has promise, especially with the uncertainty of lumber prices.

The bottleneck is at the mills which can be resolved in a year considering most have been working on debottlenecking for a year or more now.

Looks like crap, notice none of the concrete walls have utilities ran in them. Might be attractive to the usual construction-ignorant Millenial and younger but that house is going to be condemned from moisture issues in 10 years.

They have been predicting this for 10 years now. Until the cosmetics improve it is not going to be adopted on any mass scale.

Prefab kits like SIP panels would be a better option and those have never been mass adopted either.

It’s made of solid concrete, electrical is ran in the wall, and can be covered with drywall if you please.

After it's been plastered smooth maybe, or have 1x's anchored to it for the drywall to screw to. Pretty much defeats the purpose and sure as hell eliminates any cost savings. Better off with poured in place or pre-fab concrete.

I’m not up to speed on the 3D printing of homes and the article didn’t go into great detail on it. But everything from the slab up (walls, roof, doors, windows, fixtures, etc.) is “printed” and put together and then you add plumbing, hvac, and electrical to it?

Bad weather comes , I’d rather be inside brick and mortar

It’s pretty thick concrete. Seems like it might hold up well

That's the point. You probably need someone monitoring the machine, but it essentially builds the structure (all the walls) by pouring concrete in layers. Reports I've read, suggest 20%-40% savings vs. conventional home building.

A lot of time these new technologies are expensive and early adopter only but come down in price once they get enough traction. I wonder if the opposite will be the case here, be used for cheap low end housing and businesses. Then as it gets more adopted they'll add more features making it worthy of more high end homes.

Let’s just say I know this project really, really well.

First - poured in place concrete takes a lot of labor to build form walls. So that’s why you’re wrong there.

Electrical, plumbing - all infrastructure, can be and is placed in the print.

It is concrete. By way of its printing pattern, It is self insulating. It is the exterior finish and the interior finish. Therefore you remove the multitude of materials and different human trades of a traditional building method with a robot that can do it in days.

This tech is early and so it’s not perfect. Time will tell what’s it’s best used for, if anything. It’s currently being used by DOD, NASA, private developers, charities for homeless communities, etc.

But don’t be an old man that shits on anything trying to make something new.

PS - it looks a whole lot better than the matchstick box copycat subdivision thing you’re living in.

If concrete is the exterior and interior finish it looks like concrete. It doesn’t look good at all.

Vapor barrier? No Rebar? Concrete has a low R value. Hanging cabinets will suck as will interior doors. What about floor and ceiling molding?
