The author does like to from scratch, ruclips.net/user/postUgkxbnOKZBE4evMO5V2vroHeCjq6d_MV6wJO shaping and trimming wood from large blocks into fine finished products. As another reviewer mentioned, most projects require a lot of high-dollar equipment that most of us don’t have the room or budget for. But, knowing how to do these things, even if we won’t be able to practise the full stack project, is still great.
I wonder how these hold up over time without rebar reinforcements and cracking overtime.
Will hold up longer with no rebar to corrode or fail. See how long Roman concrete structure without iron reinforcement have lasted.
I bet the acoustics are nice with all of those interior ridges.
I hadn’t thought of that, but you are right... especially being ally bridged all around, the only exterior noise intrusion would be doors and windows. That would make for a relaxing home.
good point
hell no. it’s still concrete. maybe it would prevent outdoor sounds from coming in, but there’d still be a lot of reflections inside.
What can you use for inside roof, sound proof, white, for cathedral roof?
@@carrerasrivera I don’t understand. Sorry.
It would be really interesting to see why this construction method doesn’t need rebar, and to compare the performance with traditional walls
If they can use self healing concrete.
Yeah, first thing I thought was that where's the rebar
@@nespar1541 if I recall there are fiberglass and plastic reinforcements that make rebar unnecessary.
This won't fly in Cali.
Something tells me this is not normal concrete hence the rebar issue
Heard about this a few years ago and kind of filed it in the “concept” folder. Pace of innovation is amazing. So cool to see it at this stage. Thanks for stretching the horizon, Matt!
It's amazing isn't it? You can 3D print ceramic. They even start to 3D print with organic material to rebuild hearts and other organs. Freaking awesome technology with still a lot potential.
only problem with concrete is it uses huge amounts of energy in production :/ would also be interesting to see how this stacks up against factory form concrete elements in price and speed and so on :D
I would imagine factory formed to be superior in almost all areas.
@@rapfreak7797 yeah thats what im thinking too, off world forms would be hard though but i think there are easier ways then this there also :D
Not to mention the sand shortages that are happening due to concrete construction. So I can't see a brand new industry popping up when there is an existing alternative with a renewable reosurce. It will remain niche, not widely mainstream.
Cement kilms consumer very large quantities of energy plus you have the energy needs of the quarry, transportation. It would easier to just make more energy.
@@erithanis That's what they said about electric cars, but now everybody is getting in on the action. The future is now. The timid need not apply.
interior walls seem to be a prime candidate for lime wash which will permeate and smooth the wall as more and more coats are added over the years. You're painting rock with rock!
Concrete cracks and fractures. That’s what it does. You can even see it in the video above the wall outlet. That seems like a major problem that wasn’t even addressed in this video.
ruclips.net/video/_MsOXrprYXs/видео.html
The cracks are only on the outside. Thats not a problem.
@@gandalf2950 Until it settles more, and it will settle more.
I heard somebody once say, there are 2 types of concrete. One that is cracked and one that is going to crack... now who was that... wait! It was you!
Most underrated comment of the thread.
Yeah I don’t see how this won’t crack like crazy over time. No rebar either?
That is a fact, my channel and podcast is completely dedicated to 3D printed concrete and the cracking factor is something we've discussed many times. One of the easiest solutions is just a latex based paint layer on the printed concrete. The micro-fractures aren't structurally problematic.
@@kungfusing1 The lack of steel reinforcement really concerns me. I'd hate to be the beta testers with a mortgage.
@R L That opening was clearly cut after the fact, don't you think? IOW, not 3D printed.
This is weird timing. I just released a video on 3D printed homes on my channel today too. Weird timing … and awesome interview, Matt!
I’m here from your channel Matt. Your video and this one complement each other very well. Your video should be watched first. It’s more like the overview to the topic of 3D parenting houses and the environmental effects of doing so. This one here pretty much picks up right where you left off. Sure you guys didn’t work on this together ;).
@@nathanrucker4987 I can assure you we didn’t work together on this 😂, but I agree … they’re a great compliment to each other.
@@MattFerrell I was just thinking this after watching your video, haha. Fancy seeing you here as well!
@@bloodsuckingflea Nice. I love Matt’s channel.
It's actually him 😁 But here's what I originally said: Uh, channel imposter? You joined seven years ago and have one video about playing Destiny. Why are you impersonating Matt?
In my travels to every 3d printed house in the world this was one of the best! Icon is quite an impressive contender in the 3dcp space. It’s great to see bigger RUclipsrs finally giving this awesome niche the exposure it deserves!
Love your channel!
Love how dense the design of those houses are, this would be awesome with hempcrete
It would require some significant code changes here in MN. Those changes require deep pockets. Concrete needs water and there is not any on the moon. Exciting for sure.
Seems like maybe there is some. moon.nasa.gov/news/155/theres-water-on-the-moon/
@@tominglis9690 okay, got the water. Where's the concrete?
Yes there is water on the moon and cement can be made with almost no water. I presume there are mixes that dont use water, its just the easiest.
The opening cemented my interest.
Go to your room.
@@jameschristiansson3137 😂
Dad jokes have entered the chat 😂
that's a *solid* pun.
@@douglasharley2440 rock solid
This is a great idea ... especially considering what the cost of lumber is going to be doing in the future, not to mention the liability of fire.
Fireproof... didn’t hear any mention of this. Another good reason for space moon build :)
I've seen 3d painting house stuff before but it looks like they have improved the printing significantly
1) Almost every country outside of the USA is using formed concrete to build houses and commercial buildings. In other words the forms are set up around rebar and then pumped full of 4000 psi concrete. Much like they do high-rise buildings in the US. The forms are usually pre-designed on a computer and then put together on site. Very simple and efficient when they use the aluminum forms. I don't understand why the building codes are not changed in the USA......especially in places prone to hurricanes. It doesn't make any sense when you really think about it.
2) I would like to see geo-tech testing on this wall system to prove how strong it is. There is no rebar or reinforcement at all but maybe the multiple 2" layers create a stronger structure.? It's very interesting but still does not look very practicable to me. Good video! Thanks.
That is amazing. That looks like the type of homes that would work in Florida with our Hurricanes.
The speed of “construction” is amazing, and being able to lay in the electrical and plumbing is a great idea. Add a/c ducts and device wiring (cat6, fiber, etc). The future is bright for that company.
That’s Very Cool !!! The Future of building houses is Here !!! It’s Just Awesome !!! Well Done 👍 !!!
Seems like rebar or wire mesh would be needed for structural integrity. Also, the foundation work would have to be impeccable.
Fiber reinforced or micro rebar (1" steel pins mixed into concrete) would probably work. The foundation really doesn't have to be perfect at all. The 3D printer could be configured to go around and measure the distance to the foundation with a laser every few inches before starting to print. It could then use that data to adjust the first few layers to compensate for any uneven surfaces. Many modern plastic 3D printers have features like this because the glass bed is never perfectly flat and the layer printing tolerances can be 0.1mm or less.
In the shape internal to the walls it acts as it's own reinforcement.
I assume the concrete is continually mixed. Otherwise the concrete still in the truck would harden if the lower layers had hardened
@@henryD9363 even still being mixed there is a time limit for using the concrete. As soon as water is added the clock starts for when it has to be used. A project I'm currently working has a 2 hour limit for the concrete mix. It takes an hour to reach the job site. Forms and initial inspections have to be done prior to the trucks arriving....and all required inspectors on-site.
@@henryD9363, I believe it's dynamically mixed on site as it's needed if that is what you mean. So hopper full of dry cement, another full of sand/aggregate, water, other stuff, all being continuously measured and fed into a hopper. That is pretty much the only way they would be able to control the consistency well enough to 3D print.
So glad you're checking this stuff out Matt! I was waiting for someone like you to give your honest opinion on this process!
With all the cool epoxies and stains and stamping techniques we already have for concrete it'll be neat to see what all they come up with for finishes
Being from NM, I can only think: When are you going to stucco that house? LoL, I know you don't have to, but for a more conventional look, and for not much more in cost, it might be the way to go in the American SW.
This technique would be perfect for NM: easy to stucco, easy flat roof, and probably rock-solid against wind.
I am form Southern New Mexico also and in my town there 99% of our homes are built on a slab foundation, and I would say most of those foundations have cracked. Mostly those cracks are benign and don’t cause any problems but only because the wood is very flexible. I don’t think that concrete walls are going to be quite so forgiving. The laws protecting home owners will need to be changed to require prestressed concrete slabs.
@@deltoncbaker AZ and CA have solved this issue (for different reasons) but it isn't hard to build an uncracking slab, ~$3k. but it has to be done at the time of pouring. After that, the slab can tilt some insane amount before cracking. In AZ the soil is all sand, but CA did it for earthquake reasons.
In a video I did with printed farms they show how easy it is to stucco printed walls
This is their demo house. Clients might want the marshmellow layers on some of the walls for an interesting focal point. I don't think most people would want the wavy lines everywhere.
Undecided with Matt Ferrell just put out a video today about the same topic, he focused on the environmental factors of it. I think when i build a house ill end up doing an icf build over 3d printed.
I think there are a few benefits of this over ICF. The insulation is protected from termites, weather, etc. on the inside of the wall. The cost should be lower without as much siding or interior framing or trim work required. And you can fasten to the walls anywhere vs planning out attach points in advance like on ICF. These 3D printed houses look bullet proof.
ICF I feel makes more sense, thinking about it from a traditional building, rough in, or remodeling sense... ICF is cheaper and easier for the everyday builder or diy types... The ease of use for icf and integration of traditional siding and walls, plumbing, eletric just makes more sense.... For example re wiring this house would be a nightmare, running plumbing would be a nightmare... The one thing that's for sure, is future owners will be eating the cost...
@@MartinThmpsn you shouldnt talk about stuff you know nothing about. Termites eat wood, specifically wood that has moisture in it.
@@chuckd9007 you should read up on ICF and termites. While termites don’t eat EPS, they absolutely burrow through EPS and can reach roof and other structural wood members in a house in an undetectable way by burrowing through external EPS insulation, like an ICF. This has led to bans for use of ICF below grade or within 6” of grade in many parts of the US. The advantage of this 3D printed house is that the foam is encapsulated within the concrete and cannot create an undetectable termite infestation the way ICF can.
@@MartinThmpsn The Perfect Block is supposedly a bug-proof ICF (they call it an ICCF). Wouldn't ICF with a membrane coating be okay and bug proof? Matt like Polywall products quite a bit. I'm not sure I've heard how they might help with bug infestation.
That interior finish is actually somewhat helpful to cut down on echoes. They could probably add a step to the printing process to smooth things if they wanted to.
Get a builder that combines this with Aerobarrier and you'd probably have the tightest house imaginable. I'd still be a bit concerned about the lack of rebar if they go to a 2nd floor with it.
All I can think of is throwing random bags of concrete coloring powder into the mix.
@zomgthisisawesomelol Of course you need to repaint it every few years. It`s concrete after all. There are some natural stones that can clean themselves like white limestone. We have a solid house with withe limestone bricks (clinker) and the house is 40 years old and was never painted. It loses the white on some points if the material was touching other materials and it reacts if it is a long time wet. But otherwise, it looks fantastic.
We have some neighbors that painted the house anyway and now of course they need to paint every now and then because the natural cleaning is gone. Sealed under color.
But concrete loses its color in a few years. Light colors faster than dark colors. And they don't have that self-cleaning in the material. So especially white concrete will get dirty after a while. On dark concrete you won't see it as much, but still.
Concrete dye bleeds for months... anything that touched the walls would be stained.
A polyurethane type coating would work well though and would reduce moisture permeating the concrete.
SkittleCrete
When my kid was younger, he'd make a sucide slurpie when we'd stop at the 7-11. That's how I imagine the colored concrete coming out of the printer.
Hey build your house that way see what you get curious
With wood as expensive as it is now, I like the concrete idea
@@stewartstewartstewart wow....
@@stewartstewartstewart oh please do explain why it is so bad...
@@stewartstewartstewart A lot of concrete is recycled, and contains slag / old concrete / fly ash etc. from other previous processes like steel-making etc. It's not as wasteful as you may think, one of it's main components also being... sand. Which is rather plentiful on the planet.
@@stewartstewartstewart Because cutting forests down is great for the environment... lol
@@VenturiLife just a comment to report on the depleting sand reserves. No kidding :/
I don't understand why we're not advancing the tilt-up construction process for residential purposes. You can embed any exterior look you want in a precast concrete wall and actually have rebar in it.
I agree
Because that requires paying people to work . These tech ideas are based on machines taking our jobs , not because we can’t do the jobs but because of greed . They will market it as if it will save consumer money initially but the bottom line is it won’t it will just result in more money running up stream. Remember when they opened up America to importing goods from China and other countries and out sourcing businesses and manufacturing over sees. They said it would make it cheaper for us . It has not held true to that either.
Are you kidding me? You think that opening up trade with China hasn’t made goods less expensive for us?
They have. 100%.
@@jerk4628 initially it did but it’s not what you think it is anymore . The markup has taken the savings away . The only people it benefits is the large corporations.
@@undisputedchamp2568 How has the markup changed?
There's another group printing using a resin. Like epoxy. They use the robot arm to sand the walls smooth again. It would have all the benefits of concrete, with an additional amount of flexibility that concrete doesn't have.
Oh yeah baby... That is the future. Only missing the print head for the insulation.
Yep. Any kind of blown in insulation would be very easy for that machine.
It didn't look like they were using any tensile-strong materials (poly-fibers or similar) in the extrusion-process. There appears to be a crack at the corner of the bottom-left corner of the window at 11:15. Is this cause for worry? I know that brick-and-mortar constructions crack too, but the bricks still hold the wall together like a jigsaw-puzzle. What about the printed material?
Because there's no rebar it won't have the same corrosion concerns as traditional concrete homes.
@@rhiannahardy-janisch1716 But it could have cracked, break, and collapse problems
@@henryD9363 there actually has been structural testing done on these buildings but yes cracks and breaks are big concerns. That's why I actually don't think this method is sustainable. 3D masonry machines and 3D printed bricks are more likely to be used for a primary building method.
There's another crack on the top of the outlet at 5:54
@@rhiannahardy-janisch1716 Ikr, that's why I specifically suggested polymer-fibers (nylon, polyester, kevlar, heck, even chopped glass). These are regularly added to aggregates against cracking. Would add _some_ tensile strength, imp, just like carbon-reinforced PLA does in 'normal' 3d-printing.
The dust between the rolls...have fun cleaning! I would plaster the walls.
You need to go out there when they do the blower door test.
Yes this! having seen this in prototype phase I would like to see the final results.
How about the safety? for example fire?
Maybe adding a vertical roller to the printer to smooth out the beaded surface?
The texture actually adds to the aesthetic imo but everyone has different taste they could add extensions to the machine for different looking finishes
man this would be great, I am sure it would be hard to do. That cement mix prob is fast dry to prevent sag and slumping. But if you had a special bit behind the print nozzle that would press and remove excess, and possible carry the excess back to the print hopper. That would be pretty great, I would think most people would pref a smooth wall.
Yes,,,,I agree,,,,this is in progress,,no doubt,,,,,,what's to come !!!....cool,,,,,the wiring and plumbing will always,,like in all homes,,,be individual,but a trowel,or roller,will be soon...crazy shit here,,,,,,,hope this dose not drive the price of mud up too much though. ! ....😯
They actually have some that smooth as it is extruded from the hose. This version just doesn't have that.
Great Idea smooth walls would be much more apealing to the public.
tbh I would do an intererior finish, but I do love the complete airseal, and the freedom to do curves etc.
wonder if they will add some way to smooth out the shapes in the future.
I was wondering if you would ever talk about 3D homes! Thank you for being so diverse and providing your channel with awesome new content time and time!
Again*
Perfect for an exterior/interior stucco finish
the genius of this is by partnering with NASA to design "Space houses" they are basically getting free R&D funding and then transferring the knowledge to an earthly application. this is how u get ahead.
Would of been great to see a finished model to show people...
WE cant have everything
I've filmed many of these homes for my channel, a few are finished but because it's so early about 40% of the videos I've done are at projects that were still under construction.
@@automateconstruction so all these Houses projects started at the same time, an Zero are done or completed???
They have in Austin
Reminds me of Play-Dough stuff I would build as a kid. I think I will wait and see how this one stands the test of time.
What a nice dude, great technology too. Wish somewhere down the line they can achieve something similar with hempcrete, as a more sustainable and greener alternative.
Curious to see the settling cracks after a year.
Big crack above the electrical that they showed, maybe should do double layer on interior too.
Bro you guys don't know how strong concrete is.
The way they are setting the walls make it hard for anything bad to happen.
I think concrete can withstand 2000lb per square inch
what about cracking from foundation issues
I just heard about this a few days ago .. very excited to watch this.
Not a word about relative cost?
Money is not a thing ... ooooon the build show!
Nope, never.
I’m not the only one saw that vertical crack, right?
5:51
i saw it also lol
That's perfectly normal with any concrete construction. It would be covered with some caulk and paint.
I noticed numerous cracks... very likely from the curing process itself. Makes me wonder if there are any fiber reinforcements in the mix. There are numerous changes I would make right off the bat with this design - chief among them would be a troweling tool attached to the print head to smooth out the walls... would be relatively trivial to make them smooth on the show side. The next move would be to mix and match the pattern vertically to create pillars in the wall - this would be to exploit the properties of fiber reinforcement.
And, of course, guides for inserting rebar... likely wouldn't need much given the design they're using already, but I'd prefer to have some support columns every 4-8' with steel in it when it comes to multi-story buildings or supporting longer spans.
That wall won't fall over without thousands of hammer blows.
Don't mind the surface crack.
Finally, someone who is actually making a difference in how homes are built.
I’ve covered many other companies like icon influencing the automation of construction
Military has been using it for years to make structures in the field. Though the system they used was a 1 foot wide nozzle.
you should check out Monolithic Domes. they have been around and improving since the 60s. and in my opinion are fare more practical to build since it doesn't require a robot, just concrete or shot-crete tools, foam insulation, concrete, and an inflatable plastic fabric, that acts not only for the build process, and stays on, but is also the vapor barrier itself, and can also then be covered in almost any type of hard surface. and has survived easily against many natural disaster type events. fire, hail, lightning, earthquakes, tornados and hurricanes, to name a few. im not so sure an unreinforced 3d printed thing like this can match the qualities of a monolithic dome, and, really, any builder can learn how to make one and it wont require coding knowledge, or knowing how to run a robot so... yeah, it has a lot more benefits and convenience to its design and specifications. it also has many real world examples that have survived such events with ease, some multiple times with minor cosmetic fixes and cleaning jobs, let alone structural like any conventional stick house, or likely these 3d printed buildings... concrete is nothing without reinforcing...
@@EddieSchirmer thanks for the info. I’ll check them out!
@@servus47 certainly =) i am glad you hold an interest in the possibility. it i am honest i think the 3d printing could be better for garden construction walls which dont need to hold up to surviving extreme weather and geological events. i can imagine it being used to make wavy fences, with embedded wire frames sandwiched between two layers of concrete, since it could be reinforced that way as well. but, for homes, i woudl trust a dome to withstand disasters far more readily than these in the video. in any case, cheers, and have a good evening =)
love how excited the guy is about his biz
I been trying to get this kind built in the desert. For a second floor use the icf forms.
Thank you for this cool video - I have been following Icon for a while now. Can you comment on the lack of reinforcement in the concrete and explain why it is not a problem or weakness in it's design? I love the idea of a 3-D printed concrete structure, but I don't trust the integrity of non-reinforced concrete.
Yeah, this seems very much like a solution in search of a problem - but no doubt they know how to throw around the buzzwords and get funding. Appears to be slower than ICF or concrete block, requires incredibly expensive machinery, and the wall is built with zero reinforcement.
It will be interesting to see how this evolves using materials on site. That will be the extraterrestrial test is if it can print using dirt and rock from the surrounding area to print the house.
This project is using on site earth to build its structures; pretty neat ruclips.net/video/w9sXqxccRPM/видео.html
Very cool! I think I would want the interior walls plastered smooth. House built like a storm shelter. No need to go to the basement.
Just a couple of uestions remain. I did not see the reinforcement/earthquake structure. I also did not see how to manage remodels/changes in sizes of windows or doors. I'm all for electrical run through conduit, that just makes sense. Wall pipes give rise to concerns should a maintenance issue arises. Love this new tech! Really appreciate you bringing this to us!
I'll believe it when I see it.. They've been saying this is going mainstream for about half a decade
"houses for a fraction of the cost" WHEN!???
Agenda2030
There is ALOT of cost that goes into a house. Wall framing with this product will not decrease the overall cost much since everything else is still the same price, or more.
@@mph5896 I know that's what their claim always is which is why I put it in quotes.
They have decent arguments to why it would decrease cost, but the actual technology doesn't seem to be nearly efficient enough
It's not just framing though from what I've seen. It supposedly also works fine as a complete interior and exterior, so no siding, sheathing, or drywall needed to be installed and inspected.
Matt realizing his passion for air tight building, has been leap frogged by new tech.
Love the 3D printed house development. Hope it gets wide adoption quickly.
Not to mention the excellent soundproofing. :)
The look reminds me of rammed earth buildings. Since you can add stain to concrete, I wonder what it would look like with certain layers stained to give a "stratigraphy " to it.
Unreinforced rammed earth...
Every since I got a 3d printer I started to see the world in layer lines.
Thanks Matt, I have been looking forward to this review.
I was waiting for this video from the build show thx Matt!
I'd like to see these structures tested in a wind tunnel or with 2 x 4 cannons to see how the walls stand up to tornado flung debris.
Why? Our current houses don't stand a chance
@@BGraves what do you mean? We test those kinds of structures fairly regularly and can reasonably build homes that withstand 150mph winds.
You can print a dome shaped house.
A flying 2x4 won't break a concrete wall.
@@MrBeard-ig5zc send it flying fast enough and you'll be amazed what a 2×4 will fly through.
Considering how hard it is to get into a house in North Texas right now, I would absolutely go for this.
Have you tried using the door?
Have you tried moving to California
Major shortage in DFW right now. People are generally paying 20 points above asking. Been like this for a minute too.
@@MatthewCharlesGorham The supply chain problems with lumber had slowed new construction way down. Normally, the quickly growing supply of new homes keep prices moderated.
Were' being beaten out by cash offers 10% over ask that are waiving the appraisal. The day the house is listed! Nobody making offers contingent on their own home closing has a shot.
In the last 2 weeks it almost looks like panic buying.
@@blaydCA Really, there are good prices available in "Los Angeles"? It is quite a big area you know. Not sure where you are seeing low prices....
Love the tech! Would want to trowel over interior and exterior for finished look. Stucco. What about rebar reinforcement in seismic areas? Horizontal welded wire between layers maybe, but still need vertical reinforcement. Voids every 4' that had rebar tied to slab/footing that could be filled with concrete?
I've been wanting to see more information about 3d printed homes YESSSSS
Thanks for helping the guy out. This is without a doubt the future.
Curious if there is any steel reinforcement for tension strength as concrete just has compressive strength(I’m in Cali so EQ concerns comes to mind)
Yeah, there is a reason that earthquake country avoids unreinforced concrete. Would need some steel in there to keep that house from ending up like a house in haiti after the quake
From their website, it looks like this isn't traditional concrete, but a proprietary cement based mix that is specifically designed to be printed... The call it lavacrete, and they have a proprietary blending and pumping truck that feeds the printer. If you are interested, this is an interesting read about the state of the industry.
www.theseus.fi/bitstream/handle/10024/355813/PinedaFigueroa_JoseLuis.pdf
One interesting note from the referenced research paper is that this kind of computer controlled pouring process (what 3D printing is at its core) lends itself well to high temperature cement mixes that would be dangerous if used with traditional concrete techniques... Blends that are poured/extruded at quite elevated temperatures that give the cured cement a much higher tensile strength.
The cut away shot shows standard rebar embeded in the interior wall.
Lots of concrete now has fibrous reinforcement, or I have seen small metal barbs that can be pumped, and provides similar strength, I think the engineering channel covered it with demos of traditional Vs fiber Vs metal barbs. I haven't seen any evaluation for earthquake performance.
I agree with some other comments regarding A. No rebar or reinforcement. B. Inside surface will collect dust and be a cleaning problem.
Looking forward to seeing the "Risinger Print" branding 😂👍 Love the potential of this tech!
*so sweet.* a complete 2-story house built like that would be so incredibly energy efficient, and quiet, and pest-resistant, and fire resistant...lol, and basically bomb-proof.
Yeah it is built like a nuke shelter or a basement.
Nope. That concrete is more fragile than monopours with rebar.
No talk of the insulation or r value
@@sparksmcgee6641 doesn't have to...not only with the foam injected into the wall interiors, as matt discussed with dude, because of concerete's extremely high thermal mass, the house will effortlessly stay warm in winter, and cool in summer.
@@douglasharley2440 your wrong on te thermal creating efficiency. I build concrete homes and structures. Concrete doesnt change the energy required to maintain the environment.
Have fun remodeling that.....
Had the same thought. I’d probably talk to the builder about using a hybrid build and use the 3D for the spaces that would be the most unlikely to be renovated (garages, etc) and stick for the rest. Not sure if/how that affects integrity of the whole thing but I’d have the conversation for sure.
No kidding.
@@tdunn2 It would just have to be accounted for in the design phase. The concrete walls would be, for sure, load bearing, and whatever timber frames are built inside would just have to be specified as superficial or load bearing when built.
The other thing is generally remodeling you are leaving the exterior and changing the inside. But yea how would you add an outlet or sink I get that.
14:00 "...if you don't like the Stay Puft marshmallow look." 🤣🤣 Actually, I kind of like it!
I love this concept!
Is there is some sort of fiber reinforcement in the concrete to prevent cracking? There doesn't appear to be...
Judging by the giant crack under the window he was standing by starting at 8:25, I am guessing not
@@BassFearDave Dang, you are correct. Good eye.
Ones built in ny used a fiber in concrete
@5:51 there's cracks as well
Would like to have seen a over head shot of the whole “printer”. What did it cost to build and develop? Opens up a world of possibilities!
I am sure that with its use will come innovative improvements. One such is reinforcing, which could be partially solved by running a soft wire ahead of the play-dough factory outlet. Another may be a micro 'trowel' that follows on a robotic arm to alter the exposed surface appearance or to improve the start/stop inconsistencies. Very interesting concept.
For those that care: producing concrete releases huge amounts of CO2. This has come up in others of Matt's videos. Whereas wood construction is a fantastic CO2 sink (It's mostly carbon & water!) So as long as a wood frame house is standing, all that carbon is locked up.
curious about the shear strength in a seismic zone

With no rebar it's a good question. They would have to honey comb the print with fibre reinforced crete. It's worth seeing where it goes as I live in a seismic zone (Pacific Northwest).
None.
You and undecided dropped this today
Noticed the same!
With lumber reaching all time highs it makes sense
bring it already been waiting for these for awhile
That ridged look on the interior will only last long enough for the people who actually have to live in and clean these houses to kick up a fuss. It shouldn’t need to get to that point. Other than that I love the concept.
I think a traditional top coat could be applied to exterior. Likewise a thin plaster finish floated to the interior walls. For me though, the lack of steel reinforcement in the concrete would be of concern, especially in areas prone to earthquakes.
I applied to them over 6 years ago, wishing to join their mission at some point!
Been waiting for years for these guys to come to market
I think this is super cool, but I have so many questions.
1) If you tap con pictures can you do a good patch or do you have to stucco?
2) you can do round corners, but can they still do a 90° corner?
3) When they start integrating pex plumbing how do you repair or replace it?
I have more, but seriously this is fascinating.
What happens in 15 years when a pipe needs replacing? Once you carve into that wall it's going to be hard to make the patch look good.
Just plaster after repair? Just a thought!
Pex has a longer life expectancy than 15 years, closer to 100 years. You do just as is in any other traditional home on a slab construction. You rent a jack hammer and buy some Type1 cement.
You embed conduit/penetrations in the wall as it's being 3d-printed, and then you run pex through the conduit. If the pex needs replacement, you just pull the old segment out and the new segment in, no need to disturb the structural wall.
Lime render would be perfect for those walls, inside and out. Would help with water/moisture to proactively deal with damp and keep it away.
This type of house would be great for people who lived in areas where wild fires are. Concrete doesn't burn. I can see homes like this taking off and be the new normal. If it was mine in the end I would stone it since I'm a Mason. I love stone and brick walls that are curved.
Concrete and steel structures don't burn per se, but they fail systematically and lose integrity, spreading the fire and smoke to the other compartments. Steel loses strength and expands at temps where wood maintains full integrity and concrete cracks, explodes and spalls.
Wild fires would bake the inside. My new neighbors had pictures of the piano mostly melted and the sheetrock powdered when touched. There home didn't burn but was bulldozed and they moved here.
Finally!!! Thought you where stuck staring at 2X4’s forever 🤣
B1M channel did a good video about (1st) multi story 3DCP buildings in Germany this year too (might have been one story cant remember)
That was a multi story! I covered the same building!
I have never heard width pronounced like that ever, actually took me a few goes to figure out what you meant Matt! :)
He is actually saying "wythe", which is a term used in masonry to describe the thickness of a wall in units of brick. For example a double wythe wall is 2 bricks thick, triple wythe is 3, etc.
@@joshschaefer6138 ok! Great, now I know what he is actually saying. Learnt something new. Thanks ;)
For those who are talking trash about this....... all of us have seen and been in many buildings that were made of concrete. I even watched first hand as a jail was built using precast concrete slabs for the interior walls, exterior walls, even for the floors/ceilings between levels. It went together like a giant Lego set. Granted, those precast slabs were reinforced with rebar, but this concrete can be easily mixed with fiberglass for reinforcement. The cracks in the house shown in this video suggest that no fiberglass reinforcement was used. Yes driveways and sidewalks crack, but they are often not reinforced with anything, depending on local code. The cement (not concrete) used in driveways and roads, also has larger aggregate mixed in which serves much more for volume than it does for strength. Cement driveways, and even roads, are subjected to the constant pounding of vehicle weight, as well as salt in the winter, also motor oil, transmission fluid, and other fluids from vehicles, which unlike water, soaks in, does NOT evaporate, and weakens the cement. The city I live in recently dug up my street, all the way down to soil, including our driveway aprons, the part of the driveway that is between the sidewalk and the street. When they poured the new driveway aprons, and a few sections of sidewalk as well, there was no rebar, or even wire mesh used. The concrete used in this building, is not going to be subjected to any of that abuse. This is also a relatively new way of building residential homes, so naturally there are going to be a few things that need to be addressed, but in less than 10 years of use, most of the issues will have been worked out. Another thing to consider is the astronomical price of lumber, and the incredible number of man hours needed to build a similar size structure. Lumber is up around 200% from last years prices, demand is HIGH, supply is low, and there is no sign of relief anytime in the near future. 1 or 2 people can put this up in about a weeks time, as mentioned in this video. Material cost and labor hours are dramatically slashed. I can easily see how labor unions would not be very happy about that.

Here is a precast 3D printed house that can be as large and complex as the owner wants. ruclips.net/video/1WXHJn7z-hM/видео.html
Awesome tech Matt
One additional comment, Matt u mention it’s disaster resistant. What about earthquakes? Seems fairly rigid for seismic zones which need more flexible structures.
Concrete is the highest safety standard in earthquake zones. EVERTHING in japan is concrete. Im sure someone is now going to link to the 1 percent of housing the thats wood
Without rebar, how would it do in a seismic zone?
Probably turn to dust.
I live in Japan and we are developing concrete 3d printing processes for a high seismic activity region like Japan, so basically you have another robotic end effector that actually follows the printhead and inserts stainless steel rods in it after that is done, you can use a welding method called wire arc additive manufacturing to weld the rods together. For columns and structural supports, you'd print the internal part first and then wrap the columns with rebar and then print a second layer to cover it with an attachment that directs the concrete onto the rebar instead of downwards like when you print the walls.
They did a few of these in NY last year with rebar whole house. They sold a few as well.
@@edenassos a monolithic dome is a million times more convenient lol
@@EddieSchirmer Developing processes are never pretty.
I was ready to move into a house like this 20 years ago and will someday!
That is AWESOME!!! Building in space makes it SO much cooler!!
Being in California, I have to ask how it holds up to earthquakes? We use wood here due to its ability to shake, rattle, and roll.
