Such a cool application of today's technology! Also noticing how the concrete walls dull the heavy echos within the room while you talk to each other.
Rounded walls tend to help to diffuse/cancel out soundwaves that would normally be amplified by regular flat/linear walls. Plus, concrete doesn't really like to resonate like wood studs and drywall.
its a cool house. But 50 years ago people were making concrete dome houses. It was a bounce house filled with expanding foam, and then covered in concrete. The issue with those houses today is water gets into the cracks, freezes, makes bigger crack, repeat year after year. The problem isnt with concrete. The problem is with it not being a smooth wall that sheds water. So, while it looks beautiful, I wouldnt expose the concrete. Paint, poly, 4' eves, something to keep those walls complete dry.
Yeah, the exterior should be covered up with bricks!
Those interior walls will be dust magnets. Wonder if the robot maid will wear provocative rubber gloves.
I wasn't quite clear on heating cooling or lighting either. Dusty collections would indeed make the space more uncomfortable :(
It’s a model. I suspect most would prefer to plaster the walls like in the bathroom.
@@hippie-io7225 radiant heating and cooling in the floor would handle that.
@@michaelgreene9889 how would radiant cooling handle condensation if it's in the floor?
@@rcmrcm3370 good point. The house will need a dehumidifier or two depending on square footage. I have one in a poorly ventilated bathroom.
Would interested to see how this would hold up in more Northern climates, as well as what type of scale is possible.
My thoughts exactly. The way the concrete walls are built, the inner structural wave connects the inner and outer walls, so there’s areas where concrete bridges completely from outside to inside. Over a long winter I would expect cold to migrate all the way through the concrete creating cold strips along the interior wall that would attract moisture and dust just like you see in wood stud walls except much worse. They also glossed over the attic-less, flat roof but that would have to be engineered for the cold too.
-Belinda Carr has a video on her YT channel ('Fibonacci 3D printed house') where a company called Twente Additive Manufacturing has built a similar 3D printed concrete house in Canada. She talks about some of the shortcomings of their prototype design, which were mostly related to details/finishing. Total build cost was $100K.
@@walterrutherford8321 The thermal bridging was also my first thought, but the top view at 12:35 makes me wonder if they've eliminated major bridges by standing up the outside/interior walls with a true gap (unlike every other 3-D printed concrete walls I've seen previously that have a bazillion major thermal bridges). It would be great if more details on this topic were shared and if they have in fact achieved concrete walls without substantial thermal bridging.
@@walterrutherford8321 *no way.* you can clearly see the wall structure at 2:30, and there are no thermal bridges to the exterior. as he said in the discussion, there's an 2-row-thickness interior bead, and same for exterior bead, and the two don't connect. the interior/exterior beads come close to touching, but that only at spots for windows and doors, and there is spray foam insulation filling the interior. they didn't go into details around the sealing of gaps around windows and doors, i'm sure that's a key part of their proprietary process.
I wondered that also. Another thing i see this as dirty because all those ridges on the inner and outer walls collect any dust.
First 3D printed house I’ve seen that didn’t look like a poor replacement for CMU. They actually used the technology for it’s strengths. Maybe it has more potential for residential than I thought, we’ll see.
They're going to have to overcome the "artsy fartsy" factor which only really works in high end, big dollar construction.
If they can play to the method's strengths while still delivering a home that's hits the center of the market, great. Foam filled concrete walls on an insulated slab that can deliver traditional rectilinear living spaces would be huge.
@@PhotonHerald you can, however it is inherently cheaper to build a nicer looking home as they described in the tour, full frame windows cut cost and complexity down, the curvature adds strength, for interior you could easily convert to straight walls and doors and basically have a traditional style home
I wonder how easy it would be to clean? Hand prints, dust accumulation, oil in the kitchen. Unsealed concrete could very quickly begin to look trashed
Was just thinking the same thing. Have to maybe get some custom tools for it. That concrete has a lot of texture to it and would definitely accumulate dust in every single little line.
Thanks Matt, 3D printing has come a long way. To see this house just shows that a house can be strong and beautiful. I would like to see the mechanical room. What was the door test results? What are they using for fresh air exchange?
I’m expecting they are using air. 😋🌬
It’s been three years since Icon debuted their 3D printed house abs thus far they have built three. Additionally, they are only about to build one floor with the concrete pouring robot, and use traditional wood framing for higher levels.
This is a solution to a problem that does not exist. We have had the technology to build with masonry and concrete and metal framing for well over 100 years. I don’t see what need this is addressing other than it’s a significant upgrade over garden variety wood frame and dry wall homes.
The problem it solves is having to pay for subcontractors or labor to do custom masonry work. All they have to do is bid slightly under the builders using traditional labor until they drive them out of business and pocket the difference. Eventually, the cost savings will come to the consumers but it will take a long time until there are enough builders with the new technology willing to pass the savings on to them. There is nothing wrong with the technology itself.
Based on what I see this enables much more creative designs and easier to insulate. If this technology scales it could easily half the cost of single story construction
@@mattbrew11 It would depend on the local labor market as to how much it would cut the costs. I didn't see any shape that couldn't be done with traditional materials. You can run foam between two brick layers just as easily as between two layers of extruded materials. I saw one presentation elsewhere that I think was pretty cool where they mixed it with traditional construction to prefabricate just the really complex features. If you can truck in the printing equipment and the materials, you can truck in pre-fabricated panels and they go together faster. At least compared to the technology currently being used. As far as creative design compared to traditional materials, take a look at Gaudi's La Sagrada Familia.
I would love more detail on how thermal bridging was prevented. Looking at 12:35, it seems like they tried to create true gaps without thermal bridging with the "ripples" providing the structural integrity, but it's hard to say given the distant view in that shot. I'm also unsure if at the windows they specifically tried to prevent concrete thermal bridges running along the window jams by having complete breaks in the concrete where the windows go in (looking at 12:35, it seems like it, while the details are unclear at 6:30). Any concrete thermal bridging is going to undermine the claims about the possibility of an "R-40 wall" (3:45), so spending more time here on the details would be much appreciated to truly support the building science mission.
For every 3-D printed home I've seen, I've always felt like 3-D printing was a hammer in search of a nail that created severe problems while solving relatively little. Maybe this house has solved many of those problems? At the very least, the bits shown in this video suggests some progress is being made. Well done!
I'm fairly certain the concrete wythe is continuous from outside to in surrounding the windows. He explained the window opening is tapered and the window depth was determined by where the window panel fit, so I would assume no special accomodations were made to eliminate thermal bridging around the window.
I thought it fairly clever the way they trimmed around the window. It looks like they used a diamond saw blade to create a slot where they inserted a piece of 1/8" dimensional steel. That left it looking very clean, but also an excellent conductor for cold.
This is some extremely cool stuff going on. I can’t wait to see the next versions of these builds.
I love his enthusiasm for the technology and the build. It's contagious.
Thanks for covering the cutting edge in building Matt. I saw a video on 3D printed homes roughly this size being built for only $4,000 apiece. This HAS to be the future. Your videos that show innovations in building are the videos I watch the most.
Love this house. In floor electrical is awesome, hope to see more of this in the future.
I'm of a different mind on in-slab electrical.
It's an avenue for dirt buildup.
They're tough to service.
And what happens if you have a flood?
Sure, GFI. But...this will take more thinking.
Would be interesting to see experimentation with colorants and reflective material in the mix.
I was thinking this is the perfect base for stucco homes
Beautiful. Love it.
The texture on the 3d printed walls has an additional benefit to help dampen sounds too, yes? Less echo / noise in the house.
This is so cool. Would love to see more 3D printed interiors as well as they evolve the technique.
That is an amazing home, thank you for sharing this with us.
Great video Matt. I've seen a lot of 3D home videos but I like how you pointed out the detail work.
The flat roof reminds me of Eichler homes in Palo Alto CA. It looks awesome.
It appears that the interior and exterior walls are directly thermally coupled at all window and door openings. That would be a major problem in a northern climate.
Yep. There are still ways around that.
Stunning, from start to finish.
I was really impressed at the natural acoustic performance properties in those rooms, it felt like that natural curvature keeps the RT60 super low. Very very cool.
Wow, that house is incredible! Nice job guys!! Looks really good!!
So awesome! I wish they could incorporate hempcrete into this technology. I'm sure its easier said than done.
All technologies ending with crete sucks. Hemp, eps, air, paper etc...
Yes I hate airports and skyscrapers. Crete products haven’t helped society at all.
@@ecospider5 Obviously not concrete...
Yeah. They need a highly flowable mix and I'm not sure you can make hempcrete quite that thin...
you just put hempcrete in between the walls like insulation
Its nice to see Jason's narrative evolve/mature/fine-tune compared to previous interviews (e.g. with Jared Gross). Matt also knows to ask the right questions in an encouraging tone, which helps too. :) Finally a house where they proudly leave the print-layers uncovered. Nice.
Matt, with some of the rounded walls it would be easy to make a safe room or a hidden gun cabinet or safe in general. Just thinking via you past videos on hidden rooms.
Rubber roof properly covered with plain elastomeric water based non toxic coating, just because rubber deteriorates in sunlight, is the way to get a forever roof. Now maybe this stuff as a final coating? But you really want it to reflect the sun back out into space!
Hi Matt always great content from you.
Could you provide more info on that concrete aggregate overlay?
I am having a hard time picking it up on the audio...thanks as always.
I think too many people are reacting badly to an early prototype. This is a long play. This is Tesla 2004 when they only had the crappy roadster and it did a bunch of things worse than a conventional car, though the potential was very apparent. This is not gonna come and take your job tommorow but it's definitely got a big place in the future of how we build. Id not bet against it! Good luck Icon!
That Mars/Moon mention from Matt got my wheels turning.
@@bothellkenmore especially if you are refining aggregate from the surface of the planet. Also massively cuts down on number of specialized connectors, fasteners etc you need to bring. Just raw stock and maintenance parts for the machine
Much excitement from a building enclosure consultant over here.
I've been following Jason and 3d printed homes for awhile and this this is certainly more fancy then any other one they have built so far
The details are so good!!
Yep. For a custom home, it's cool.
As various housing ventures in the past have show, these types of layouts don't really work for a living home.
Uneven walls, and odd shapes make it hard to decorate. Hard to refresh.
Maybe not as hard as it was 30 years ago. But still, it adds complexity. And that complexity comes out in additional cost.
It may think it may be hard ,but you have to think outside the box .you'll have to get creative,it's a rather unique home, so you'll have to think different.
'Hard to refresh'?
Meh, folks who buy this are 1st wave kind of folks. They buy it and hype it for self aggrandizement then sell to next self promoter in 2-5 years.
It will still be novel enough for 7 or 8 different buyers over the decades.
If you want a suburban cookie cutter neocolonialranchcapecod style house head to Round Rock (N Austin suburb) they're popping outta the ground like weeds
@@willbass2869 Yeah. You can't necessarily decorate to fit to YOU. You have to decorate to fit the house.
The problem that I see is with thermal bridging from outside to the inside.
Master mind!!!!!! Brilliant!!!! Untouchable!!!! Period
I absolutely love this and would love to see how this could look in Upstate NY.
Wow, that’s beautiful!!!👍🏻🔥
I honestly put 3D printed homes in the same boat as VR. It’s a gimmick that won’t really take off because it’s not that practical, and will only serve as a “cool” factor for very few people.
The layers are also very inconsistent, if my 3d printer printed like that I'd think something is wrong with it. Maybe plastic is a better material for 3d printing. I think it looks rather ugly.
Exactly, this looks really cool and it's the cool factor that sells the house. This house probably has $200k in wood finishing by itself.
History will prove you wrong.
@@stevepasquarella823 If you listened, you would know this house was not for most people. If this house were to be listed, it would go for at least $670,000. Icon has built lower cost homes and even an entire community in Mexico.
@@scottmohrman7789 no it won’t. 3d printed homes have been an idea for at least ten years and it hasn’t taken off.
*SWEET HOUSE!* love this channel so much, thanks.
Awesome project!
What product was used for the bathroom plaster?
It's gorgeous. I love it.
Love this design
Wood does want to conduct heat like concrete......Softwood is R1 per inch. Concrete R0 per inch.
Excellent stuff bro
Cool looking house and it shows that building methods can evolve. Often the difference between cool and atrocious is in the eye of the beholder. Many comments here point out some practice problems. Personally, this look is not for me but I appreciate the ingenuity and effort to advance the methods.
Thank you! I would like to learn more about how they are integrating reinforcement (rebar equivalent) to these builds, or if not, why not, and what the limitations are because of the lack of reinforcement.
Concrete doesn't need rebar when/where it is in compression. The rebar is to support tension. So, rebar going to be in the floor and ceiling. Single story walls should be purely and always in compression (if on flat/level/strong slab., which itself will need rebar). Add a 2nd floor and there will be areas of tension.
I would make this my retirement home, when that time comes.
@@csf1757 I think perhaps I am biased by being in California. Yes concrete's strength is in compression, but sooner or later a concrete wall in California is going to experience some fun tension stresses. :-)
3D Printed Bunkers is what I need right now. Anyone else?
Very cool. This is the right direction, the new technology demands a new aesthetic...along with functional improvements. That's where you can leverage the benefits.
Great. Now hang a picture or mirror on a wall that's all wavy and un-plumb.
This has been the problem with all sorts of radical construction paradigms. I have a friend who owns a geodesic dome. The concept of "furniture" is a nightmare in a spherical environment.
You can't get traditional furniture that fits well. And custom furniture is hideously expensive.
Wiki up "Xanadu Houses". One of the reasons these attractions failed was because they were impossible to update. Everything was pre-cast in place.
And you can't just take a chainsaw or wrecker bar to structural members.
Would really like to see more about the mechanicals on this one. Also will they build me one?
This would sell so well in Florida where the hurricane requirements are so restricting.
I wonder if a temporary reusable form could be used to create flat smooth sections of the structure to help frame in windows and doors. You could use that technique on the bathroom wall as well so little to no plaster would be required. I would imagine the major challenge would be nozzle/head to form clearance. The workaround would be to angle the head like some modern CNC machines are capable of.
Very cool design elements and possibilities. As others have said it's going to be some time before local AHJ are going to play nice with it. AC in the floor is a great element just not gonna be allowed in most places.
How did they do blocking behind the kitchen cabinets or the towel bar?
Beautiful house .
I've been working with a 3d printer now for about 4 months. The biggest challenge is first layer adhesion. So I'm curious on what is being done for first layer adhesion from the printer to the foundation slab. I has to be dust free, level and and the right temperature and thickness for best adhesion. This is true with engineered materials such as PLA ect. It would be nice to see some destructive tests for sheer strength.
Matt when you did the drone shot at the end of the video there was a house 2 doors down that had like lime green wood I'm assuming. What is that and is it common there where your house build was?
The floor to ceiling windows are great
That’s a beautiful house! Lots of thermal bridging, but otherwise, the structure seems like it would be very efficient.
Sadly, we’re probably a long ways from this being widely accepted tech (at least stateside…maybe EU, South America, etc. would be easier market).
So cool, I want this technology to go mainstream yesterday.
Exactly right
Very cool construction! But common Matt those poor plants you’re stepping on 😱
that shit awesome !!
If you could build a duplex, and have the machine, move along a path to the next duplex, and so on that you could build a row of duplexes, or quadriplexes, etc, and make it more affordable.
It would be interesting to see "disposable-houses," where the material gets recycled.
And finally Matt, sorry my questions didn't come all at once. would these be good as they said this house is in Missouri (I may be wrong there). I'm from NEPA so I'm not familiar with Missouri's climate, however against tornadoes and floods this would be resilient. I think Missouri is a little too far in from Hurricanes. but this also helps prevent wildfires.
Open cell foam for the void spaces. How is the house airtight then since concrete is also porous?
I would think this would be a design that would lend itself to radiant heating and cooling by putting tubing not only in the slab but grouted into the interior wall cavities as well.
That’s a really interesting idea
Would be interested to hear how he gets r40, I would had thought that there would had been significant thermal bridging due to the concrete.
The wall is hollow and braces like a Tstud.
Remember, the walls are hollow concrete structures. They fill it in with spray foam.
You'll see some bridging around doors and windows due to the "just drop a pane of glass" construction method.
But for someplace in TX or California, this is no big deal.
Minnesota? Might be a problem.
Only some of the walls are r40, they achieved that with spray foam insulation. Think the baseline was r25 for the bulk of the concrete walls
How are the steel transition strips installed?
Love it I want one.
That's SWEET, NOW I WISH I WAS LOOOOAAAADDDED, DUDE!
what about seismic activity and the need for bar in masonry structures, are these 3d printed structures reinforced?
Hi Matt, it seems that ICON doesn't do any other residential building except planned communities and they no longer have a usable contact link on their site. Would you know if they only doing high-end residential and no longer a builder for hire on individual jobs?
The roughness of the walls would tear my arms to shreds. But I bump into walls a lot.
Build bigger and wider.
How would they do a two story ? I really like these . I live in Austin and have been following this guys progression it’s truly amazing . My neighbor Mr. Rose is the head professor of engineering and 3d printing at UT Austin and we have had some awesome conversations about the pure intelligence of this guy . God bless !
They don't do a 2 story with concrete because in a 3D printed set up, they can't use rebar in the walls because it would get in the way of the printer arm. Without rebar, you simply cannot build a house like this with a second floor. They currently build 2 story 3D houses with the entire 2nd floor framed with lumber.
Pues manos latinas. Aún que les faltó. Pero aquí su servidor fue el encargado de realizar parte de esa obra. Tan genial.
Super cool, can't wait for this to be part of the future. Would love to see this expanded to look at 'printing' in different areas (for cure times) and the ability to print off-grid is appealing to 'off-grid' homes.
I've the 2 floor homes. Wood on 2nd floor and cement on 1
I actually found out two of my friends now work at Icon. I am curious what time and monetary savings are for these builds. I love this design, but Lake | Flato is quite the pricey architect.
Hi Matt, I’m super interested in deploying 3D printing construction in the Midwest! It does get a wee bit colder, and the wet season might be a bit more sustained than yours (though the total amount of rain is pretty similar). What are some ways to start thinking about executing beautiful 3D printing home design in areas outside of Texas? Thanks! PS. ‘prototype’ or ‘minimum viable product’ are both terms I’ll be using once I get started :)
There are companies that make and sale concrete 3D printers however there is a lot of science that goes into the mix. The walls are printed over weeks but the whole wall has to dry together and not in layers.
I think that this is the way the technology will move forward: Unique high-end homes. When enough people realize they can have a house that looks like a cross between a seashell and a castle, and it'll be extremely strong, this will take off.
I thought they were septic tanks based on the Thumbnail Picture. But I do like the idea of 3D printed homes
Press X for Jason....I'm so sorry. I also want a home built by ICON so BAD. Got to check out the Austin build a month ago and boy I love it.
How soon can I get one of these in Wesley Chapel Florida? (Tampa)
Gaudi designed the grounds keeper house in La Sagrada Familia with curvy walls to add structural strength to the house, old ideas made new by technology
Very cool. As a 3d printing enthusiast I can't stand the layer lines though.
I wish this would gear up fast enough to help in South Louisiana..all the hurricane rebuild wait and materials cost is awful
When will they make a 3-D printed DOME? It seems to me that would be ideal for tornado and hurricane resistance.
love this...
Are these going to be available in Puerto Rico anytime soon?
Matt, are they able to trowel flat the bumps so to speak as they go or is this just how the houses have to be on the outside and the inside?
The tour of the bathroom was to show how you can plaster the walls smooth, though they talked about not doing it in general to leave the technology exposed.
The best news about 3D printed walls is that they can be plastered over and the rough uneven surface will be gone. Then maybe the power outlets could be at a sensible height for those who find reaching down to the floor is an unwelcome challenge.
How do you dust the ridges in the house? lol. A swiffer duster would stick to it. You'll literally have to vacuum every square inch of wall with a plastic bristle brush. And often. Eesh. Add some plaster for a smooth finish and this would be even better.
I like this better than ICF, HIGHLY prefer the insulation method, but how strong are those walls vs ICF vs traditional? I'd definitely use plaster inside. I'd add hurricane rated windows and radiant heating running off a solar roof. What about basements and/or 2nd levels?
A utility trench style basement that occupies a relatively small portion of the total slab should be easy to integrate, just plan ahead to place beams where the printed walls will cross over the trench. A second floor could be easily added by dropping steel beams into the printer, if the printer can be made 2 stories tall. I think some of the wall cavities might need to be reinforced with rebar and traditionally poured concrete.
Hurricane windows?....Austin?
Oh dear....
@@willbass2869 did you catch the part where he said he lives in Austin? Yeah me neither. Pack up your 24th chromosome and GTFO
@@willbass2869 I don't live in Austin...but yes, anywhere. I'll take the storm proofing and security. Especially with floor to ceiling windows!
@@mattbrew11 it's in Austin. Don't be a d-bag
Alright you got me. It's very impressive.
thx
Might be able to purchase a new house just from the costs of those wood finishings and windows this house has!
Would you like to build those houses in Denver, Colorado? I want to work with you guys. That is very interesting.
So you've got Great insulated walls and then tons of windows r 3 no cool project
There has to be a lot of skill in to putting the rest of the parts together to meet up and make that concrete to wood transition look fluid clean crisp
I would be interested to see how that house did on a air leak test
Should do fairly well. Since the wall is concrete with spray foam fill, the main leak points will be the shell penetrations (pipes, utilities, doors and windows) and the roof interface.
It’s better than a normally built home there are tons of videos on this exact topic .
@@TeXasDadBod Any links? I know there's videos for various other concrete structures, like ICF. But I haven't seen leak tests on this particular home.
Their extruder and axis need better calibration, Isuggest printing at least 500 benchies to get the best result. Also they need to print their own mods for their 3d printer to make it better. Is the stl file available?
Jay the Florida pool pump motor bearing repair guy When Service Calls Longwood approved ! that was good info 👨🔧Matt
