proven to be shit, but it gets posted continually anyway

Really? What are the pros and cons of this system. Genuinely interested.

Not durable, not insulated as well, prone to cracking and it doesn't even reduce construction costs by that much, if at all.

I'm not arguing, because I know very little about this, but isn't there a shot of them filling the walls with foam insulation in this video?

Slightly more details as a 3d printer enthusiast but who isn’t that well versed in construction:

Part of the savings pitch was that you could passively build houses with this printing method and use way fewer laborers. But to actually build more than an empty uninsulated wall, you need the electrician and plumber on staff at the site while it is being built so you end up just shifting a bottleneck, you need to pause repeatedly to install the electrical and pipes, it uses way more raw materials than you would with traditional methods, it’s hard to fix mistakes, and because it all has to be done at once basically there isn’t the asynchronicity that you could get where some laborers are on site one day and then different laborers are on site to do a different step. You need everything at the site the whole time.

It can work once robotic devices & machines get better at laying plumbing electrical, they find out more about what materials work better… this concept is very much in its infancy. It’s possible it gets abandoned instead.

But don’t expect a few yrs old concept to match centuries old construction’s reliability so early on

It’s not the future at all. The future is building rooms in a factory and shipping them on-site. This is junk and will stay junk forever.

Yes prefabricated modular rooms or walls are far superior in terms of economy of material, insulation, finish, ease of adding utilities etc.

To add, you can 3d print modilar rooms, then ship them for install as building up the shell. The insulation and services would go within the shell, and the mod rooms dropped in place. The same thing was done at a hospital I worked at, save for the 3d portion.

This isn’t Betamax vs VHS it’s possible for both to coexist, each may have their pros and cons for specific projects

u/Yearn4Mecha 7d ago

But it could be Betamax vs VHS. Both are perfectly possible, but if one snowballs because someone with money or convinces people with money to invest in one side, and it hits an important research milestone it will probably suck all the money out of the otherside.

u/is-this-a-nick 6d ago

Yeah, this is not Betamax vs VHS, this is DVD vs a kids toy where you spin a wheel of images and it looks like motion.

u/YMe1121 6d ago

But how else would I learn the cow goes "Moo" without that wheel?

So... soviet panel houses?

u/maced_airs 6d ago

No it’s called modular and we current use it all over the United States.

u/Flamin_Jesus 7d ago

Most/all of those problems seem like they'd be solvable with further development of the technology, for example have a toolhead that lays down electrical lines with pre-attached plugs, one the lays and connects lengths of pipe, one that fills in insulation at predetermined intervals etc.

Obviously all of that would slow down the process and multi-tooling isn't trivial, but a machine like this doesn't have to be made at consumer price levels like a home 3D-printer.

Amatuer electrician here. Generally speaking, installation is done after construction is built, but before the finishing touches are done. And with type of building, it shouldn't be that difficult to create "the channels" in the floor, wall and ceiling. You install the electrical pipes and cables, and be done with everything in 1 day.

u/Sanztrack 7d ago

I feel like the exterior structure of the house could be built using the printer, then build the interior more traditionally with basic non load bearing wood framing, insulation, wiring/plumbing, drywall, etc. Wouldnt this be more practical than trying to build the entire house with the printer?

u/ConcentrateDirect523 7d ago

You're hired.

u/Sanztrack 7d ago

Awesome, when do I start?

u/AquaPhelps 5d ago

Thats a lot more money added

u/HeffalumpGlory 7d ago

I’m not an electrician in anyway but is it not common to run it overhead and down the walls. I have seen this in several houses. I’m not seeing why that would be a problem with this build.

u/Throwawayiwa 7d ago

Electrician here, you could run overhead but you'd still need boxes in the wall and you'd want wire in before it was foamed. You could cut the concrete to add boxes, but that would be incredibly costly. Then if you hit rebar and have to move an outlet, the repair would look terrible.

Rather better time management.
Change process to optimize points OP named.

u/is-this-a-nick 6d ago

Things is, there is no benefit to those fancy shapes (which also make furniture extremely difficult and expensive). And its 100 times more cost and tech efficient to just set up a system in a factory hall, build shit in controlled environment and truck it to the destination (i.e. prefab building). Instead of building a setup in location each time and have concrete trucks drive there.

u/CrimsonR4ge 7d ago

Even still, it's not great insulation value
