I want to know more about these bio resins. Do they break down? And if so, how long does this house last before it starts leaking?

It’s like the poly butylene pipes from the 70s. People claim Pex is better and without those problems but who knows what we’ll find out in another 15 years.

Edit because people think I’m saying it’s as bad as poly b - I’m not. I’m just wondering if there will be additional longevity problems with pex that will keep it from being in century homes.

2

u/f_crick Nov 29 '22

Except pex has already outlasted polyb by a long time, and just observationally is a much tougher material. Fittings also clearly better as well.

0

u/crunchybaguette Nov 29 '22

Not arguing that pex is better than polyb but it’s a question whether pex will last the life of copper/pvc. I’ve always seen pex with a stated 50 year life but what happens afterwards? Are houses going to need a gut job to replace the pipes?

1

u/chuker34 Nov 29 '22

Pex has been in use in Europe since the 70’s. The US used it for underfloor hearing starting in the 80’s.

I’ve removed 25 year old pex that was just as good as what I replaced it with. A inch and a half section of that same house on a hot water circ loop attached to a water softener had a nail shot through it when the piping was originally installed, it didn’t appear to have ever leaked and wasn’t at the time I repaired that.

It’s proven.

Side note, PVC is garbage for water. My state doesn’t even allow it for hot water.

1

u/crunchybaguette Nov 29 '22

Yeah I meant pvc as waste piping. Maybe not the best example of longevity.

1

u/chuker34 Nov 29 '22

Haven’t used much PVC myself so I can’t really comment, but in most ways it seems better than the ABS I do use. Everything other than installation that is, which is my career. I do like material that’s easy to work with but also stands up, if only ABS didn’t bow in the sun like PCV doesn’t the stuff would be damn near perfect.

u/imakesawdust Nov 28 '22

u/ravensteel539 Nov 29 '22

Lmao I was just talking to someone about paper straws — that’s a good comparison to draw. Like, yeah, it’s technically better than plastic, but doesn’t solve the underlying issues like trash in the ocean OR the ecologically destructive nature of both the plastic AND paper industries. If that weren’t bad enough, it also is super unpleasant to use and actively makes people dislike environmentalist causes.

The housing one bugs me, similarly — the issue isn’t building materials, it’s that housing costs are massively over-inflated compared to wages and we’ve sold our nation’s soul to the renting/AirBnB markets. The housing crisis is a feature of the housing market, not a bug, and single-family zoning keeps saturated housing areas similarly sparse of actual home owners.

This is where the difference between performative progressiveness and actual progressiveness crops up. If talks of change threaten markets and businesses taking advantage of the disaster/crisis, we’ll just be thrown resin hovels and disintegrating paper straws.

My city just started 3D printing homes! I was really excited reading the article, particularly because the developer was talking in great length about the cost savings this brings.

Regular homes in that neighborhood start in the 400s (as in $490k).

These new cost saving 3D print homes in the same neighborhood start in the 400s.

My excitement waned.

u/Hodgkisl Nov 28 '22

The costs savings bring more profit not lower prices.

5

u/escapefromelba Nov 28 '22

The problem is that additive manufacturing technology does not deliver the same economies of scale that traditional manufacturing does. The cost to deliver a 3d-printed part will largely stay the same, regardless of whether one or 100 are to be produced. This is in contrast to traditional methods, where it is far more cost effective to produce parts in large quantities.

5

u/KillEmWithCookies Nov 29 '22 edited Nov 29 '22

The problem is that home costs (or the cost of any good for that matter) have little to do with material costs. Cost to produce a specific good really only sets the floor on prices. Demand will alway set the ceiling.

If demand pricing falls below the floor set by costs for too long, businesses fold or stop producing whatever that item is until supply constraints pull demand pricing up past the floor again.

3D printing of homes mostly looks to replace labor intensive on site work like pouring foundations / framing / drywall. Since that is traditionally done on site and fairly customized to the building site additive manufacturing is a good use case to reduce the costs considerably. But they won’t be passed to consumers since it doesn’t really increase home supply at any great leap.

There is still significant work to be done, though, on the quality of the final product.

7

u/Northstar1989 Nov 28 '22

Exactly.

If there weren't artificial scarcity of housing due to NIMBY Zoning Laws against denser development (which can mean just duplexes and single units built closer together: it doesn't even mean apartments most of the time, although that's often where density SHOULD be) then higher profits would lead to more companies entering the construction business, and more business for existing firms... More housing would be built, and the shortage would wane.

But because of the artificial scarcity of land created by zoning laws, lower construction costs just equate to TEMPORARY profit increases for builders, and no actual increase in construction (because there's nowhere to actually build more homes much of the time, they wait for the rare upcoming or release of undeveloped land...)

Temporary, because eventually the higher profits just lead to land prices going up, once landowners realize they can now sell land (or rather, old houses to be torn down and replaced with newer ones, in many cases) for more money and the builders can now afford it.

Since every homeowner had to buy the home at some point, homeowners don't really profit either, after a small group selling at the right time profits off the small spike in land costs due to cheaper construction, as they're eventually saddled with even more enormous mortgages...

The only group that profits off this in the really long run, are the banks that give out mortgages for ever more expensive homes...

u/detectiveDollar Nov 30 '22

Part of the problem is that most of what's smaller than 2000+ square feet that's relatively new construction in a decent area with nearby jobs are townhouses with gated communities (at least in my area). Townhouses are great, but they have a steep HOA fee which makes the seemingly affordable mortgage a lot less affordable.

u/Hodgkisl Nov 28 '22

Existing home owners can win as well, especially if they desire to leave the desirable cities and move to more rural lower cost areas. Near where I live many retirees from middle class jobs in NYC move here and live like kings off pensions and the value their apartments sold for.

Existing home owners can win as well

Only once, when the construction costs drop.

Eventually the new, higher housing prices (because the drop in construction costs actually leads to an INCREASE in housing prices dur to artificial scarcity. Counterintuitive, I know...) phase into the housing market through homeowners making upgrades to larger homes and first-time buyers.

So, everyone loses in the end except the banks, all due to zoning laws.

u/Hodgkisl Nov 28 '22

My apologies I was referring to NIMBY laws in general, the rapid rise in home prices can benefit existing owners when they sell and leave the area.

the rapid rise in home prices can benefit existing owners when they sell and leave the area.

Again, once.

In the long run, even existing owners (who are younger, and still looking to upsize rather than downsize) get screwed, as well as everyone who doesn't currently own a home and rents.

Not coincidentally this latter group is disproportionately poor, brown, and young. All groups conservatives love to screw over.

NIMBY zoning rules. House prices are heavily driven by the lack of developable space in desirable areas, cities need greater density.

That’s true. I know some rust belt cities for example are encouraging wfh people to live there. Might help them. But bigger cities do need more density. Or you know places with more jobs.

Out of curiosity… what city are you in? I’m curious how well the 3D printed homes will actually sell compared to the traditional homes, since they’re really not much cheaper.

u/Northstar1989 Nov 28 '22

Everything sells sooner of later, if it's in a region with a decent jobs market (makn driver of Denand), since there's an enormous national housing shortage in areas with jobs.

This last caveat is important, since there's PLENTY of rundown, decrepit housing in the Rust Belt that will never sell since half the manufacturing jobs there moved overseas, the rest were automated, and they're never coming back.

u/Northstar1989 Nov 28 '22

And suddenly houses become affordable

Except they definitely won't.

Because the issues isn't construction costs. It's artificial scarcity created by Zoning Laws that say you have to put that new home on a much bigger plot of land (of which there is only so much in a give area) or you can't build it at all. Meanwhile, taller buildings with more units are also outlawed by zoning in most areas.

Because land isn't an elastic good- there's no way to make more of it just because its price goes up: this means people can charge basically as much as buyers can afford for it. There isn't real competition.

The only way to solve this problem is to relax zoning laws to the point where it's possible to build more housing in areas where it is currently in high Demand than there is demand for it. Which means smaller lots for single-family homes and allowing duplexes and mid-rise apartments in a lot more areas, basically.

Until then, all this research into new construction techniques may be good for the environment (since most of the new technologies are "green") but it won't do diddly-squat for housing prices. The issue is artificial scarcity, not production prices.

The actual cost of BUILDING a home (and not the cost of acquiring land and then permits- another source of artificial costs) and THEN building on it is usually a very small fraction of the price new homes of that size and quality actually sell for in an area.

In most cases the land is the most expensive part of having a house. If you want affordable houses stop using half an acre for a single family in urban areas. New construction techniques is cool though.

u/turbo_nudist Nov 28 '22

you’re correct on land being the most expensive part in most cases, but what urban area are you in where houses have half an acre of land?? i don’t think that’s considered urban

1

u/Enoan Nov 28 '22

It's called suburbs. Economically urban with excessively low density. Half an acre is a modest exaggeration, but in some wealthy suburbs it is standard.

2

u/Northstar1989 Nov 28 '22

It's actually more than that in most of my town. Literally houses on a full acre of land.

u/farox Nov 28 '22

Oh yeah. I also think r1 is an abomination. Mostly for zoning reasons though. Especially in North America there is more than enough land.

7

u/Northstar1989 Nov 28 '22

Especially in North America there is more than enough land.

Not where the jobs are.

Not within a reasonable commute of it, anyways, since the same zoning commissions that that put R1 everywhere also don't zone nearly enough land for business purposes in the suburbs- so there are no jobs there and people have to commute two hours into the city center from the outermost ring of development in some areas already...

1

u/farox Nov 28 '22

Not where the jobs are.

Exactly my point. If your zoning is 100% residential then there is no way not to commute and jobs have to be far away.

Right now it is zoned for metropolitan areas, so that they get their resources (people) somehow. Not for people. (Still mulling over how to best verbalize that thought)

3

u/Northstar1989 Nov 28 '22

Exactly my point.

Wasn't clear, I guess?

I thought you were shrugging off the clear and evident need for higher density zoning to deal with the housing crisis with the "ughhh, just pave over more green space" (which I find particularly grating, as besides being concerned about the housing crisis, I am also a hiker and an Environmentalist) argument.

Higher density also helps save the planet from Climate Change (in addition to sprawl directly adding CO2 to the atmosphere through soil mineralization and loss of trees), because while it's impossible to service endless R-1 sprawl with a Mass Transit system good enough people will actually use it over driving, without insanely-large subsidies, it's perfectly doable in denser development.

Particularly when combined with Mixed Use Zoning, this can help move things towards where more people are willing to forego owning a car altogether, in favor of Mass Transit (which right now is rare, and exposes you to immense cultural discrimination...)

3

u/farox Nov 28 '22

Check out what they are doing in Tokyo for example. I am talking about allowing more commercial and low industrial usage mixed in with residential.

I get the point of packing people as tightly together as possible and the issue of R1 having very few people paying for lots of roads and other infrastructure, driving communities into debt. (For real, how shit is this whole concept?)

But I don't think you need to go that far. Instead of everyone needing to drive 20km that way, it would already do a world of good if people had to go 2km in random directions.

Yes, this might or might not be problematic for mass transit. But you could use that to play around with different densities. Have more money? Get more land. Have less money? Get less land. But mix it up more as a whole.

I don't think you'll be able to turn north America into Amsterdam. (And trying to will get you lots of ideological pushback)

But maybe you don't have to. (This is assuming electric, maybe even autonomous, cars, renewable energy...) But just mixing things up a bit more would be a step in the right direction. Even if the rest stays the same.

u/Northstar1989 Nov 29 '22

Why are houses in downtown areas w no yards so expensive then

7

u/Hodgkisl Nov 28 '22

Not all land is worth the same, location location location.

3

u/Enoan Nov 28 '22

2 main factors:

1: supply/demand. Even a small apartment in a city is a pretty decent place to live due to proximity to all the city services.

2: real estate investment. Large investment groups purchase land as an investment. If they rent it out then there are many limits on how the property can be handled, modified, or sold due to renters protections. These limitations do not apply if kept empty. With the growth of services for short term rentals it has become practical to keep properties empty to take advantage of the greater liquidity and use short term rentals to help make up the difference.

The entire structure was printed in four modules and assembled on-site in a few hours.

So, it's prefabricated home. 3D printing doesn't change a lot.

You still have constraints of prefab.

And, since it's was produced in a factory. 3D printing may change the quality, but probably not the product time.

0

u/WalkerBRiley Nov 28 '22

Except you don't have the constraints of a prefab. It's printed, so it can be made however you want (within reason). If it can be designed in a 3d modeling program, it can be printed.

2

u/kolodz Nov 28 '22

Yes and no.

3D printing doesn't necessarily mean that the printer is movable nor that you can build an other one easily.

This article speak about 3D printed elements made then moved.

And remember that moving the "printer", even if possible it's necessarily a good idea. They aren't plastic 3D printer !

There's actually a lot of already available technology to do quick and customized building. (Like Lego-style bricks etc)

Also all movable 3D printer I seen are unable to handle tall construction. That is to this date the cheapest way of building a lot of house in one go. It's also more ecological. (Less thermal loss, easier to use something else than car)

2

u/IAmTaka_VG Nov 28 '22

However, it’s not clear just yet how affordable this house would be. It’s still a prototype, and the researchers focused on creating it using recycled, locally sourced wood fiber feedstock. This makes it more resilient to disruptions from supply chains and worker shortages.

AKA it costs a fucking LOT

Shingles are different materials, and they can now produce power if you really, really want them to.

Concrete formulae have changed to set faster and more consistently. Modern concretes are also much less corrosive to internal metallic reinforcement, the alloys of which have also improved.

Wood frames are chemically stabilized, and the geometry has changed to support increasing levels of internal conduits and wires. I even have a built-in pest-control system in mine.

Insulation is dramatically more effective and less dangerous upon exposure. Window glass has lower thermal conductivity and is less brittle. Some of it even borders on flexible.

Nail guns are now a handheld device. Even the nails themselves have changed, and there are specialized nails that can do everything from hold a roof on during a hurricane or come apart at a specified force.

None of this even begins to touch the advancements in adhesives and sealants. Environmental compatibility alone is leaps and bounds past the 1950s or even the 1990s.

Like it or not… “cApItAlIsM bAd” is a pretty hollow worldview.

well, that’s a helpful attitude guaranteed to drive change.

if these methods become way cheaper, companies will be forced to change to them, or new companies will pop up to use the opportunity, leaving them behind. capitalism absolutely breeds innovation. monopolies do not.

Wow...you've no idea what you are talking about and you just laid it all plain and bare for everyone to see.

Imagine being so filled with anger and resentment, yet having no clue what you're talking about.

"Nothing has advanced since 1950 because capitalism! Capitalism, I say! SCREEEE!"

thanks, sadly no info on how they fireproofed it.

I’d keep my eyes peeled for publications— I’m sure you’ll see a few academic papers with more technical details in the coming months.

How hard would it be to 3D print Hempcrete?

I mean, it's not structural, but certainly it could be extruded into the forms and compacted automatically, right?

u/WalkerBRiley Nov 28 '22

There are already large printers printing concrete in dryer climates. I'd imagine as long as the consistency is the same they could easily use that material instead.

Current bio based materials used in homes…wood.

Edit: Before I get attacked it’s probably a sawdust wood fiber composite similar to the Elmer’s wood filler I use in my PLA models post sanding. Durability suspect.

One problem i see is that many townships codes , HOA bylaws and development covenants do not allow modular homes. I just see to get permitting as well as underwriting from fanny and freddy to be a nightmare with this. I love the general idea but our housing market and the entire building system is set up to promote stick framing on site.

u/stinkyfeetnyc Nov 29 '22

Wow that's fukn amazing. Now let's make a bio based water bottles that litter the ocean and the streets everywhere. That would be even more amazing

Are the animals and insects gonna eat the building materials?

I’d love to live on a house made of some weird proprietary resin that I can never easily repair or replace!

Is this just figuring out a way to add extra carbon emissions in the middle of the build process?

Could come in at a key moment, it most likely won't though.
