Okay cool but I feel like you spent more time detailing solar than you did on the 3d printed structure. How long did it take to print? How does that compare to build time of a stick built house or cement block house? What's the insulation R value of the walls? What are the tolerance considerations for setting window & door frames? Is the concrete cut afterwards for openings or is there sufficient offset to frame in openings traditionally? How long do the walls take to dry before more work can continue? How repairable are they? What's being done for exterior waterproofing and vapor barriers? If you get a future opportunity to do a video on a 3d printed house, these are the details that matter to the future viability of 3d printed houses.
This is what I love most about the channel. Its more than a machine and software review channel. I appreciate the constant search for 3d printing in our world and every day lives and emerging 3D printing tech. I love the effort and perspective you bring to this community.
I've seen other 3d printed houses, but the big questions are where is the insulation, remodeling, updating electrical, and plumbing would be a challenge
The approach of filling the walls in this home with concrete is actually atypical. The rest of the homes that emergent printed have hollow walls. The electrician laid wire in the walls without conduit, because it was unnecessary, and provisions were made for plumbing during the prints. Insulation was blown in between the walls after the walls cured. Look for news articles about the one that was printed at Reginato boat ramp in Redding California for a peek. Remodeling was a big question I had too, and there are some plans for that moving forward. However, they'll have to cross that bridge when they get there.
If it's transitional housing the cost would be subsidized, particularly if it's super energy efficient. I'm sure there would be a lot of credits available. Also, not sure if the idea would be for people to be purchasing these homes if the idea is to go from homeless to this type of home.
I'd like to see what that house would cost to build without solar, without metal roof, and with standard windows and doors. Also I'd like to see star wars style huts being 100% printed. You might have to very slowly print the roof, but I think its plausible.
I love to see how 3d printing gets even more important. Even tho i already knew of 3D printing houses for a while i enjoy seeing it inspected by a true 3D printing professional. Thanks for your great work mate :)
I saw an article recently where a community in Texas was being built with 3D printed homes to provide cheaper housing. Then I saw they were selling for over 500,000. Apparently rather than go with the idea that cheaper construction means cheaper sales, it meant wider profit margins so they basically tacked on a novelty fee.
They are not they are being built in Georgetown Tx a couple of miles from me. The inside walls look just like this they also 3d printer the counter island the base is printer. Cost is high than a local build house but they add the solar panels, which. Resale the price is expected to be lower than the local classical build homes . They will go under water on the value.
@@windforward9810 Doubt it. Wall panels are more than enough to cover the inside look if you don't like it and the inside of those places looks incredible to me. Large island breakfast bar and sink, huge bathrooms, I'd love to live in a place like that. If it wasn't half a million.
The problem With wall panels is that you have to attach them to the cement wall, every add on add cost to the house. I think the house is great for areas that are rural areas that have less personal to build a house. West Texas and eastern NM would be great area for these houses. Even Midland-Odessa Tx out there due to the shortage of labor. They fill a need in some areas just like he stated the coast that are subject to hurricanes. Not in The Austin area or heavy populated areas that are not subject to those conditions. Cost could be reduced by putting on metal roofs this would also lower your insurance cost on the house by a huge amount. Some area because it is concrete you just will not be able to build those houses due the base ground being sand base, So that would leave out some areas in west Texas , because sorry it will crack than you will have problems. In Georgetown the base it’s built on is solid rock, a mix of granite and other hard stones, so let’s see if the the houses will hold up on the coast where most of the land is a sand base. I’ve seen cracks on the base before some times they get huge after 20 years that is when the major problems will start to show up. It will be great as a temporary house that will last maybe last a little longer but will not hold its value.
You mentioned that the cement mixture has a greater percentage of fly ash. I’m surprised by that. Fly ash is a common additive in geotechnical grout mixes, and it’s been almost impossible for the local suppliers to get ahold of it in significant quantities lately.
Wow, I was thinking a 3d printed house could be a viable option until you mentioned the price. Granted these are Texas prices but I've seen manufactured homes that look bigger for a third of that price. Still a really cool technology.
I agree. Price turned me off on this build. They built one in New York state and it sold and that house was the same price but twice as big. Interesting the price difference.
Omg so glad you gave us your perspective IRL of a concrete AM house. I'm so excited about these! Your claimed experience with framing, electrical, etc of traditional homes gives you a great perspective to detail these and I'm really thrilled to see you speak on this video. Do a deeper dive! I've heard there are non-subsidized AM home communities going up in the US (maybe TX?) and experimental communities going up in other places, not just single units.

That's a well-apportioned house for their target price with solar and battery system, the grey water processing and it was just beautiful inside. Price reduces with scalability, but it seems like a great target. Loved seeing different aspects id 3D printing and their applications.
Love 3D printing, but just as the beginning for desktop FDM, whole building printing has a ways to go; every time I see one of these videos I see so many reasons for concern in the longevity of the structure.
I'm curious what the comfort factor of living in this house would be like? With the walls being 1.5 inch layer of concrete on the inside and out, with concrete added between: I'm wondering what the R-value of the walls is like because concrete typically have very low r-value of 0.1-0.2 R per inch. I assume R-values increased somehow, being the design was part of an energy efficiency competition? Is neat idea, but would have like to see more details on the construction method, and some cost breakdown. (type of foundation, walls, window/door install details, how water pipes installed, etc .. and how costs of each compare to traditional home construction)
So couldn't you use forms and lay out the conduit the same way and then pour your concrete? That would be better eco friendly because you wouldnt have to run a robot layer over layer over layer which would consume a lot of electricity. Everything else is just normal traditional (now) eco construction so really 3d printing a house is a net loss. More energy to produce, more specialized tools, more cost for the foorltprint size. Form built poured concrete house would be cheaper.
Being that I live in Maryland and a Solar business owner, I was bummed when they moved the Solar Decathalon out of DC. It was so much fun to check out. Lots of cool concepts.
to get the price down make a big square or rectangle. There is too much wall per square foot inside. It takes more power to run the AC, more for heating if you do that in LA, more materials for the walls, etc. Round is great too but doesn't work with many modern building materials. Also how is it insulated and reinforced? Is there any insulation or reinforcement in the thin concrete walls?
@1:59 you can see down into the wall and they're using z ladder reinforcing wire laid between x number of layers. I'd assume that after the walls are printed, they drop reinforcing bar vertically into the cavity 4 feet apart and encased in a grout mixture.
Hmm. I'm wondering whether a type of brick made from sand and waste plastic (a composite) could serve as another form of "3D printed" house, but in a more pick and place fashion. If there's a way to airtight seal the bricks without mortar, that would mean homes designed for disassembly :D
add a cnc machine to cut and prep support wood and conduit and have a crane on the printer frame so you could cut the wood and joinery so with a few people to guide the wood in and drill into the pre drilled holes
Bro, do you even know what a $150,000.00 house cost that isn't on the West Coast? What should happen is Boxable should start experimenting with 3D Printing.....lower their $50k home even lower.
Boxable already got told the fastest way to improve their process by sandy Monroe. End of the day additive manufacturing doesn't work in a factory like boxable. But pre-made forms and fast expanding foam would churn out a house every day.
Isn’t that the whole point though? These students built a house to comply with California code and were able to do it for what looks like ~$200/sqft. Of course in places where labor/materials are cheaper you are going to be able to build a stick frame house for less.
Pretty neat, but for this style of construction to really take off it needs to be WAY more economical. For this kind of square footage (or lack thereof), and the intended purpose (transitional housing) this price is absolutely missing the mark. If you want to help people get out of homelessness, you can't ask them to pay a quarter of a million dollars for a house. This needs to be priced closer to $100k or even less if they really want to help anyone.
My house was 175k has a main floor with full bath and 2 bedrooms,kitchen,living room, dining room,, a second floor with half bath and 2 bedrooms, a finished basement with one half laundry,bar , tv room and second half with divided wall a wood shop, a detached garage, a four seasons porch, central air, solar,gas heat 🤔 thinks that’s it. If 150k is cheap and that’s all you get that’s crazy I know location matters but come on
You either live somewhere with insanly cheap housing OR bought your house more than 5 years ago. I live in a pretty small city (about 20,000 people) in an area that is traditionally known for cheap housing. My parents bought their 4 bedroom 4 bath house (with a backyard in ground pool) for $315,000 back in 2014..... they sold it for $720,000 last year. I cant even FIND a house for less than $225,000 in my area anymore (and the one's at that price are run down mobile homes 😑) after covid the housing market has been just insane... I'd happily pay that much for a 3D printed house because my alternatives aren't great.
My college won a Solar Decathalon a few years back with some friends of mine. It's a cool thing to check out. I've been conflicted about 3D printed houses... it's like the miracle item. "I want a home, pick some stuff on an online wizard, and... go" and then a house appears. But it's also very demonstrative without showing the advantages that are needed for many homes. $150k isn't affordable. Of course, with time costs will go down... but at a time when so many places are having issues with affordable housing, they aren't exactly rushing to build sparse transitional housing... heck, they aren't exactly keen on dense transitional housing. It doesn't exactly build the homes that those who can afford it would go for, it's too big for "Tiny Homes" especially at that cost. And it's already been demoed that modular component-build houses can be done cheaper, faster, and with more customization. For as much as I like 3D printing, it is one of those things where you do have to learn when not to 3D print a thing. And with houses, the selling point for 3D printing just hasn't been demoed. I've read news article after news article, blog after blog, video after video... and they the most compelling use case is something like the moon or mars, where space is limited for bringing equipment and materials and using the surface material is basically a necessity. And a lot of time, space-missions are quite expensive so this looks affordable for that. But on Earth... bunch of wooden cubes > 3D printed home. At least for now. Stuff comes up every couple months so I'll keep looking for that _moment_, but this isn't it. But good luck on Woodbury University on the Solar Decathalon, it's an awesome event, even if 90% of the innovations of all the students who participate never make it out because of some esoteric reason that shouldn't be limiting it. Sucks being negative about this. One day... one day...
Transitional housing is probably not the best marketing angle for this process but I'm sure that probably gets the funding dollars rolling in. Apartment blocks with integrated social spaces AND services with access to public transportation and dense employment opportunities would be much better and efficient transitional housing.
I don't like the idea of filling the walls with solid concrete. It might increase the stability, but it would make it very difficult to modify in the future. Say you want add extra outlets or run some new form of data transfer or something? Why not fill it with insulting foam or shredded waste plastic or something? I'll bet my AMS could fill that in a few years.
The technology is really cool, but they've got to figure something out for an interior wall finish. That would be like living in the tiniest most expensive warehouse imaginable.
From a german standpoints, its funny to talk about carbon reduction and stuff and than you have no isolation from the inside to the outside in the walls and a complet open roth thats black. So in Europe they build a complet settlement with this technik for testing.
I don't think this adds too much - brick building can be built in similar fashion in comparable time using existing techniques. The demonstrated building still needs foundation, roof and other structures, the benefit of 3D printing here is mire hype than real improvement. Now, replace the concrete with some wooden mixture, create layered walls with automated spray of paper-based insulation using a "dual head" 3D printer and we can talk about it more, otherwise it's really just a demonstration that something like this is possible.
Yes but also like he said in the video the students were too focused on making everything as carbon free as possible which isn’t exactly cheap, nor were they too focused on making the price cheap
Very cool architecture! Only thing ithcing me as an owner of a solar power system myself is that the cells - at least in these shots - are placed exactly where the shadows of the surroundings are while all of the non-panelled roof is in bright sunshine!
I find it strange how the design of most 3d printed houses is a strange shape with curves. You can't even hang a painting on that wall. And there is no thermal isolation... there is thermal mass so if a concrete wall heats up during the day, it will provide heat all night. I think there are still better ways of building cheaper. In eastern Europe we had about $100 per square feet retail price. Prices might have doubled now. Construction should be cheaper, but unfortunately everyone needs to make a profit.
This was interesting, and I'm rooting for 3d printed structures but, you could easily build this with traditional methods for under $150,000, and a good crew focusing on the job could have it done probably just as quickly. I still wonder where the budget balloons on 3d printed structures, they're insanely OP -overpriced.
Considering how fast 3D tech has advanced, I'm rather surprised we don't see a lot more of these 3D printed structures around. And it's not like Cement is the only option. Bring on the Mud House. Heck, nothing says you have to print a whole House. Why not just the Foundation, or how about a Pool or Patio. And bonus, so long as the Grade is close to lvl, the printer can handle the rest. Plumb and Square Walls, no problem! Forming for complex shapes and curves, thing of the past.
Printing a foundation is actually kinda hard. The foundations for this house were done by a very good concrete crew. But getting the printer lined up with the foundation tie ins was one of the hardest parts of the print for this project. The students took a 3d scan to locate the walls relative to the wet set anchors in the foundation.
I have an issue with the phrase "printed house", it's not a printed house, it's printed walls. I'll also note that while that it will almost certainly reduce construction cost, the idea that it's going to deliver inexpensive housing for the masses set's an unobtainable expectation.
The 3D printed concrete is cool, but it's scalability is limited, and not sure it would make sense for many places. The house building technology I think is more sensible and the future is the Lego block style building (Gablok). But everyone being able to have a home is important, and something society should be striving for.
Agreed its a very, very cool concept but in practice its going to be far cheaper and more efficient to have the houses prefabricated off site. Something a bit like Huf Haus has done (and done very well).
@@Rick-vm8bl Check out Gablok. That's the "Lego block" building. Prefab blocks, with insulation. Easy to transport, easy to lay. We need these innovations in building.
ya they got a long way to go that size less than 50k.. but its California they lost track of reasonable housing decades ago.. what's the insulation like? a concrete slab which is what these walls are is a horrid R factor of 1 .. the quick shot of the rook looks to be almost no insulation there.. I'm hoping that got at least some foamboard under the metal roof
I would like to know if there's experiments on printing a roof. What's the max overhang of concrete? Would it require a form to even be possible? If it is possible, does a wooden roof just make more sense? Very exciting stuff!
I've seen some 3D printed homes with a printed roof, but rather than worry about overhangs what they did was printed a rounded roof separately and lowered it onto the top with a crane. The rounded design apparently helps the smaller home feel larger and allowed for more natural light to come in through skylights.
"You wouldn't download a house!" Well, actually.... > *points up at video* Yes, yes I would. Jokes aside, I've seen some stuff about these before and it's good to see the costs normalizing somewhat and interest being brought up for the concept.
I love the idea, but why not build the roof and/or second floor as a separate part similar to a smaller scale model and combine the parts. I would imagine with the right design it should work if it was printed on plywood or something and be able to separate it after transport.
Build volume is a problem. You need to print the house. Printing a roof flat and then lifting it in place would require a second setup of the printer. Also, this particular printer is quite a process to set up. Version 3 looks like it will be better.
How do you keep mold and mildew from growing in the "layer lines"? It's an interesting idea, but so far every 3D printed house I've seen has been just plain ugly. And only in California would a house that size be considered a $250,000 house. And I'm guessing that price didn't include the land. Still, it'll be interesting to see where this idea leads, and it's good to see something other than printer reviews.
You went to the Reginato boat ramp house in Redding too! It was nice to meet you Jaret. Joel it would have been great to meet you while I was at Emergent.
Mit wenigen Worten: sehr schön gemacht! Also zum einen ist die Art wie du heran gehst gut aber das Haus finde ich zum Beispiel sehr Organisch. Ich muss das Video mir noch mal ansehen aber ich glaube, darauf bist du wenig eingegangen, dass damit natürlich Formen möglich sind, die auf dieser Art und weise durch traditionelles Mauern nicht beziehungsweise nur sehr schwer möglich gewesen wäre. Bei uns in Deutschland ist das auch gemacht worden des öfteren. Ich hätte dazu einen sehr guten Link auf ZDF (one of the 2 bigest news Sender in Germany) aber ich weis nicht ob du möchtest, dass ich ihn hier rein poste? Da sieht man in 100 Sekunden wie sie das gemacht haben. Vielleicht etwas für später wenn einige 10.000 dein Video gesehen haben. Das Thema ist mega spannend! Danke das du das aufgreifst!
Das ist doch die Sache! Warum braucht ein Haus überhaupt organische Formen a la runde Ecken? Bei den 3D-Druck Häusern macht man es nur, um sich irgendwie vom "normalen" Hausbau abzusetzten. Aber es löst nur Probleme, die gar nicht da sind. Den 3D-Druck Teil hätte man auch mit 2x4" oder 2x6" Fachwerk ersetzten können.
Aber na klar hätte man das, doch wo wäre der Spaß daran? Es geht ja um Dinge die möglich sind. Ich sehe da so: Es wird in Zukunft sicher die einen oder anderen sehr unwirklichen Orte geben. An denen wird es einfacher seine eine Weiche Beton Mischung zu verdrucken und Trocknen zu lassen. Als das jemand anfängt zu Mauern. Ich gehe nicht davon aus, dass jetzt alle Häuser gedruckt werden aber etwas zu sehen und sich inspirieren zu lassen ist schon etwas. Ich Lebe in einer Stadt wie Berlin, hier ist sehr viel Beton und um es ehrlich zu sagen, auch mehr als nur Hässlicher Beton. Da wäre etwas neues vielleicht auch mal anziehend und vor allem in welche Geschwindigkeit die das hoch ziehen. Danke für deine Tolle Antwort, ich bin begeistert auch mal jemand in meiner Muttersprache anzutreffen *freu*@@Allmentux
@@3DPrintingNerd Hello Sir, I am interested in using this technology for a build in Puerto Rico. Do you know of any companies that are currently using this technology on the island?
Which problem does this house solve? Concrete uses more CO2 than bricks or wood. This house is not space efficient (in german cities you are no longer allowed to build 1-2 story buildings). Is there a reaseon why no furniture is placed on the outer walls? Maybe wet concrete from rain or condensation? How stable is concrete without steel reinforcement? I see a future in 3d printing houses, but this house is not it. How about using clay and wood or hemp fibre insulation?
I hate to be a downers but that price has to come down way past $150,000. Here in Houston I got a 3 bedroom, 2 bath, two car garage home for $120,000. True, there is a pricing bubble atm where on paper its worth more, but those cycles are every 10 years or so. For a starter home you want something closer to what a couple starting off in their careers can afford. $50-75,000 should be the price range.
$250,000? Does that include the cost of the land it sits on? That can be as much as the cost of the structure itself. Especially in urban areas where most homeless people are.
To me it looks to be about 600 square. So please explain to me how $150,000 Ready to move in is affordable the whole point of 3D printing is to be affordable. This house should be $60,000 at most based of 600 square '
My only hope is that 3d printed houses stay as projects until they can figure out alternatives to concrete (and not fillers that reduce the harmful effects by 10%). Concrete is 2nd in line behind gas/diesel in greenhouse emissions, ask Bill Gates why he's investing in cement companies right now. Also even $150k still doesn't seem like a great price for what looks like maybe a 1200 square foot house. There are steel building kits you can buy right now for $20k that can be built as barndominiums for that price point already (and steel buildings go up very quickly too because they are pre-designed and pre-built in sections). ($128/sq foot x 1200 = $153k) ua-cam.com/video/tSSjjMMKqV0/v-deo.html Steel also won't crumble away in 20-30 years and can be recycled. Obviously every structure needs some sort of concrete base (whether it be foundations or cinder blocks) but making an entire building from concrete doesn't seem to be the answer either. This seems to be solving a problem that doesn't exist. It's like all the people wanting to terraform Mars, how about we terraform Earth instead?
“Stick built” is a term I and others use to describe traditional wood built homes. It’s not me trying to make them sound weak, it’s a term we have used for decades.

to get the price down make a big square or rectangle. There is too much wall per square foot inside. It takes more power to run the AC, more for heating if you do that in LA, more materials for the walls, etc. Round is great too but doesn't work with many modern building materials.
Also how is it insulated and reinforced? Is there any insulation or reinforcement in the thin concrete walls?
@1:59 you can see down into the wall and they're using z ladder reinforcing wire laid between x number of layers. I'd assume that after the walls are printed, they drop reinforcing bar vertically into the cavity 4 feet apart and encased in a grout mixture.
Square are cheaper to build than rectangle
"Affordable" is becoming a bygone conclusion in home ownership.
Hmm. I'm wondering whether a type of brick made from sand and waste plastic (a composite) could serve as another form of "3D printed" house, but in a more pick and place fashion. If there's a way to airtight seal the bricks without mortar, that would mean homes designed for disassembly :D
Glued sandstone or foamed up concrete is the equivalent. But a pain to design with
There are cinder block LEGO type build systems out there
add a cnc machine to cut and prep support wood and conduit and have a crane on the printer frame so you could cut the wood and joinery so with a few people to guide the wood in and drill into the pre drilled holes
It’s going to take so much bondo and sanding to get this where it needs to be…
That's really cool. Those layer lines though, woof. Shoulda gone with resin.
Yeah but the cleanup isn't worth it.
@@redkingrauri3769pretty sure they’re joking about the resin, not really too strong and it would take forever to cure on that scale

Since fly ash is a byproduct of burning coal, is it really that eco friendly?
Yes becasuse in that area there have been many wild fires so free material!! Cal fire esc.
Yes, because unless we start drilling soon, people are going to be burning a lot more coal. And all of that that fly ash needs to go somewhere 😉
ALL OF THE 3DPRINTED THINGS!! Great video Joel - as always
Bro, do you even know what a $150,000.00 house cost that isn't on the West Coast? What should happen is Boxable should start experimenting with 3D Printing.....lower their $50k home even lower.
Boxable already got told the fastest way to improve their process by sandy Monroe. End of the day additive manufacturing doesn't work in a factory like boxable. But pre-made forms and fast expanding foam would churn out a house every day.
Isn’t that the whole point though? These students built a house to comply with California code and were able to do it for what looks like ~$200/sqft. Of course in places where labor/materials are cheaper you are going to be able to build a stick frame house for less.
Pretty neat, but for this style of construction to really take off it needs to be WAY more economical. For this kind of square footage (or lack thereof), and the intended purpose (transitional housing) this price is absolutely missing the mark. If you want to help people get out of homelessness, you can't ask them to pay a quarter of a million dollars for a house. This needs to be priced closer to $100k or even less if they really want to help anyone.
My house was 175k has a main floor with full bath and 2 bedrooms,kitchen,living room, dining room,, a second floor with half bath and 2 bedrooms, a finished basement with one half laundry,bar , tv room and second half with divided wall a wood shop, a detached garage, a four seasons porch, central air, solar,gas heat 🤔 thinks that’s it. If 150k is cheap and that’s all you get that’s crazy I know location matters but come on
You either live somewhere with insanly cheap housing OR bought your house more than 5 years ago. I live in a pretty small city (about 20,000 people) in an area that is traditionally known for cheap housing. My parents bought their 4 bedroom 4 bath house (with a backyard in ground pool) for $315,000 back in 2014..... they sold it for $720,000 last year. I cant even FIND a house for less than $225,000 in my area anymore (and the one's at that price are run down mobile homes 😑) after covid the housing market has been just insane... I'd happily pay that much for a 3D printed house because my alternatives aren't great.
I did buy my house 4-5 years ago and I live in Connecticut very tax heavy and not so cheap housing community
My college won a Solar Decathalon a few years back with some friends of mine. It's a cool thing to check out.
I've been conflicted about 3D printed houses... it's like the miracle item. "I want a home, pick some stuff on an online wizard, and... go" and then a house appears. But it's also very demonstrative without showing the advantages that are needed for many homes. $150k isn't affordable. Of course, with time costs will go down... but at a time when so many places are having issues with affordable housing, they aren't exactly rushing to build sparse transitional housing... heck, they aren't exactly keen on dense transitional housing. It doesn't exactly build the homes that those who can afford it would go for, it's too big for "Tiny Homes" especially at that cost. And it's already been demoed that modular component-build houses can be done cheaper, faster, and with more customization.
For as much as I like 3D printing, it is one of those things where you do have to learn when not to 3D print a thing. And with houses, the selling point for 3D printing just hasn't been demoed. I've read news article after news article, blog after blog, video after video... and they the most compelling use case is something like the moon or mars, where space is limited for bringing equipment and materials and using the surface material is basically a necessity. And a lot of time, space-missions are quite expensive so this looks affordable for that. But on Earth... bunch of wooden cubes > 3D printed home. At least for now. Stuff comes up every couple months so I'll keep looking for that _moment_, but this isn't it. But good luck on Woodbury University on the Solar Decathalon, it's an awesome event, even if 90% of the innovations of all the students who participate never make it out because of some esoteric reason that shouldn't be limiting it.
Sucks being negative about this. One day... one day...
How long does it takes to print? including the setup of the frames
Transitional housing is probably not the best marketing angle for this process but I'm sure that probably gets the funding dollars rolling in. Apartment blocks with integrated social spaces AND services with access to public transportation and dense employment opportunities would be much better and efficient transitional housing.
I don't like the idea of filling the walls with solid concrete. It might increase the stability, but it would make it very difficult to modify in the future. Say you want add extra outlets or run some new form of data transfer or something? Why not fill it with insulting foam or shredded waste plastic or something? I'll bet my AMS could fill that in a few years.
The technology is really cool, but they've got to figure something out for an interior wall finish. That would be like living in the tiniest most expensive warehouse imaginable.
you can just paint it like a regular house I'm pretty sure
Basic stud walls over the concrete solves that and they take very little time to build and are cheap.
I've got to admit, this was very interesting! Thank you.
Maybe I missed him saying it... but the irony of American spirits in the British crown jewels is hilarious
I think tiny home would be a better term in this case. As futile as 3D printed homes are, still neat.
gotta love my house with 1.5 inch layer height and 100% infill
Not like concrete dries fast enough for you to not have 100% infill though
From a german standpoints, its funny to talk about carbon reduction and stuff and than you have no isolation from the inside to the outside in the walls and a complet open roth thats black.
So in Europe they build a complet settlement with this technik for testing.
I don't think this adds too much - brick building can be built in similar fashion in comparable time using existing techniques. The demonstrated building still needs foundation, roof and other structures, the benefit of 3D printing here is mire hype than real improvement.
Now, replace the concrete with some wooden mixture, create layered walls with automated spray of paper-based insulation using a "dual head" 3D printer and we can talk about it more, otherwise it's really just a demonstration that something like this is possible.
Holy crap. That house costs more than what my parents paid for this current house. I assume the $250,000 is California pricing?
Yes but also like he said in the video the students were too focused on making everything as carbon free as possible which isn’t exactly cheap, nor were they too focused on making the price cheap
I hope you can show us more 3D Printed HOUSES on the future, Thanks!
0:22 amazing intro line! Solid rhyme 🔥🔥🔥
That is very awesome... A 3D Printed house
Very cool architecture! Only thing ithcing me as an owner of a solar power system myself is that the cells - at least in these shots - are placed exactly where the shadows of the surroundings are while all of the non-panelled roof is in bright sunshine!
designed by students. have you met many young folks?
The back fill the walls after running the conduits? Holy crap. I hope nobody needs to add or change locations of any switches or outlets.
Great video! Thanks
I find it strange how the design of most 3d printed houses is a strange shape with curves. You can't even hang a painting on that wall. And there is no thermal isolation... there is thermal mass so if a concrete wall heats up during the day, it will provide heat all night.
I think there are still better ways of building cheaper. In eastern Europe we had about $100 per square feet retail price. Prices might have doubled now. Construction should be cheaper, but unfortunately everyone needs to make a profit.
This was interesting, and I'm rooting for 3d printed structures but, you could easily build this with traditional methods for under $150,000, and a good crew focusing on the job could have it done probably just as quickly.
I still wonder where the budget balloons on 3d printed structures, they're insanely OP -overpriced.
I have a 3D Printed car for your new house!🤣
Awesome! Wouldn't be great if they use hempcrete instead of concrete?
What about isolation ? Can it keep the cold away ? And also heat ?
Considering how fast 3D tech has advanced, I'm rather surprised we don't see a lot more of these 3D printed structures around. And it's not like Cement is the only option. Bring on the Mud House. Heck, nothing says you have to print a whole House. Why not just the Foundation, or how about a Pool or Patio. And bonus, so long as the Grade is close to lvl, the printer can handle the rest. Plumb and Square Walls, no problem! Forming for complex shapes and curves, thing of the past.
Printing a foundation is actually kinda hard. The foundations for this house were done by a very good concrete crew. But getting the printer lined up with the foundation tie ins was one of the hardest parts of the print for this project. The students took a 3d scan to locate the walls relative to the wet set anchors in the foundation.
I have an issue with the phrase "printed house", it's not a printed house, it's printed walls.
I'll also note that while that it will almost certainly reduce construction cost, the idea that it's going to deliver inexpensive housing for the masses set's an unobtainable expectation.
The 3D printed concrete is cool, but it's scalability is limited, and not sure it would make sense for many places.
The house building technology I think is more sensible and the future is the Lego block style building (Gablok).
But everyone being able to have a home is important, and something society should be striving for.
Agreed its a very, very cool concept but in practice its going to be far cheaper and more efficient to have the houses prefabricated off site. Something a bit like Huf Haus has done (and done very well).
@@Rick-vm8bl Check out Gablok. That's the "Lego block" building. Prefab blocks, with insulation. Easy to transport, easy to lay.
We need these innovations in building.
ya they got a long way to go that size less than 50k.. but its California they lost track of reasonable housing decades ago.. what's the insulation like? a concrete slab which is what these walls are is a horrid R factor of 1 .. the quick shot of the rook looks to be almost no insulation there.. I'm hoping that got at least some foamboard under the metal roof
Cool!
I would like to know if there's experiments on printing a roof. What's the max overhang of concrete? Would it require a form to even be possible? If it is possible, does a wooden roof just make more sense? Very exciting stuff!
I've seen some 3D printed homes with a printed roof, but rather than worry about overhangs what they did was printed a rounded roof separately and lowered it onto the top with a crane. The rounded design apparently helps the smaller home feel larger and allowed for more natural light to come in through skylights.
Late night 3dpn early release? whats this?
UA-cam now allows uploads to be set to members only THEN public at a certain time. Tried it out!
I'm surprised I missed this one until now!
I don't know that I could ever live in a place that didn't have an oven.
"You wouldn't download a house!"
Well, actually....
> *points up at video*
Yes, yes I would.
Jokes aside, I've seen some stuff about these before and it's good to see the costs normalizing somewhat and interest being brought up for the concept.
Should have said the x y and z of the house
I love the idea, but why not build the roof and/or second floor as a separate part similar to a smaller scale model and combine the parts. I would imagine with the right design it should work if it was printed on plywood or something and be able to separate it after transport.
Build volume is a problem. You need to print the house. Printing a roof flat and then lifting it in place would require a second setup of the printer. Also, this particular printer is quite a process to set up. Version 3 looks like it will be better.
It's a student-built house _in California_, in any other state it would cost half as much.
IF IT HAD 3 BEDROOMS IT WOULD BE WORTH $250,000
even 150k is too much this should be 30 k
$250,000? That house is like a 1/4 the size of my ranch house. And it costs over twice is much? The math isn't mathing. Jeez.
Knowing corporations and banks its hard to believe that we are going to have affordable good houses in future, but IDK I hope I`m wrong
I hope so too, my friend.
I think you should have added the time it took to 3d print the house
Id like to know how it handles shock.. in an earthquake for example
How do you keep mold and mildew from growing in the "layer lines"?
It's an interesting idea, but so far every 3D printed house I've seen has been just plain ugly. And only in California would a house that size be considered a $250,000 house. And I'm guessing that price didn't include the land.
Still, it'll be interesting to see where this idea leads, and it's good to see something other than printer reviews.
Good question
The layer lines cure as a single piece of concrete. No concern of mold between them.
150k for a little shack is considered affordable now.... damn im really never going to own a home am i?
100+ videos on my channel are all about 3D printed houses!

When will you build a printer to print houses?
Mit wenigen Worten: sehr schön gemacht! Also zum einen ist die Art wie du heran gehst gut aber das Haus finde ich zum Beispiel sehr Organisch. Ich muss das Video mir noch mal ansehen aber ich glaube, darauf bist du wenig eingegangen, dass damit natürlich Formen möglich sind, die auf dieser Art und weise durch traditionelles Mauern nicht beziehungsweise nur sehr schwer möglich gewesen wäre. Bei uns in Deutschland ist das auch gemacht worden des öfteren. Ich hätte dazu einen sehr guten Link auf ZDF (one of the 2 bigest news Sender in Germany) aber ich weis nicht ob du möchtest, dass ich ihn hier rein poste? Da sieht man in 100 Sekunden wie sie das gemacht haben. Vielleicht etwas für später wenn einige 10.000 dein Video gesehen haben. Das Thema ist mega spannend! Danke das du das aufgreifst!
Danke! I really appreciate your comment on this! I will look it up!
Das ist doch die Sache! Warum braucht ein Haus überhaupt organische Formen a la runde Ecken? Bei den 3D-Druck Häusern macht man es nur, um sich irgendwie vom "normalen" Hausbau abzusetzten. Aber es löst nur Probleme, die gar nicht da sind. Den 3D-Druck Teil hätte man auch mit 2x4" oder 2x6" Fachwerk ersetzten können.
Aber na klar hätte man das, doch wo wäre der Spaß daran? Es geht ja um Dinge die möglich sind. Ich sehe da so: Es wird in Zukunft sicher die einen oder anderen sehr unwirklichen Orte geben. An denen wird es einfacher seine eine Weiche Beton Mischung zu verdrucken und Trocknen zu lassen. Als das jemand anfängt zu Mauern. Ich gehe nicht davon aus, dass jetzt alle Häuser gedruckt werden aber etwas zu sehen und sich inspirieren zu lassen ist schon etwas. Ich Lebe in einer Stadt wie Berlin, hier ist sehr viel Beton und um es ehrlich zu sagen, auch mehr als nur Hässlicher Beton. Da wäre etwas neues vielleicht auch mal anziehend und vor allem in welche Geschwindigkeit die das hoch ziehen. Danke für deine Tolle Antwort, ich bin begeistert auch mal jemand in meiner Muttersprache anzutreffen *freu*@@Allmentux

Which problem does this house solve? Concrete uses more CO2 than bricks or wood. This house is not space efficient (in german cities you are no longer allowed to build 1-2 story buildings). Is there a reaseon why no furniture is placed on the outer walls? Maybe wet concrete from rain or condensation? How stable is concrete without steel reinforcement? I see a future in 3d printing houses, but this house is not it. How about using clay and wood or hemp fibre insulation?
may just apply to emergent, really friken into this tech and how it could sustainably end homelessness
I hate to be a downers but that price has to come down way past $150,000. Here in Houston I got a 3 bedroom, 2 bath, two car garage home for $120,000. True, there is a pricing bubble atm where on paper its worth more, but those cycles are every 10 years or so. For a starter home you want something closer to what a couple starting off in their careers can afford. $50-75,000 should be the price range.
$250,000? Does that include the cost of the land it sits on? That can be as much as the cost of the structure itself. Especially in urban areas where most homeless people are.
THEY SHOULD BUILD ROOMS EVEN AT LEAST ONE YOU CAN’T CALL IT A HOUSE WHEN THE BED IS IN THE LIVING ROOM
Does it also suffer the first layer adhesion problem? How is the bed leveled?
150k later on for a roof to be wood and no layer to cover it. Well guess you can clean the roof from spider webs easily
Look up ICON in states for 3d printed houses
Oh I know ICON. Hoping to work with them in the coming year!
To me it looks to be about 600 square. So please explain to me how $150,000 Ready to move in is affordable the whole point of 3D printing is to be affordable. This house should be $60,000 at most based of 600 square '
My only hope is that 3d printed houses stay as projects until they can figure out alternatives to concrete (and not fillers that reduce the harmful effects by 10%). Concrete is 2nd in line behind gas/diesel in greenhouse emissions, ask Bill Gates why he's investing in cement companies right now. Also even $150k still doesn't seem like a great price for what looks like maybe a 1200 square foot house. There are steel building kits you can buy right now for $20k that can be built as barndominiums for that price point already (and steel buildings go up very quickly too because they are pre-designed and pre-built in sections). ($128/sq foot x 1200 = $153k)
ua-cam.com/video/tSSjjMMKqV0/v-deo.html
Steel also won't crumble away in 20-30 years and can be recycled. Obviously every structure needs some sort of concrete base (whether it be foundations or cinder blocks) but making an entire building from concrete doesn't seem to be the answer either. This seems to be solving a problem that doesn't exist. It's like all the people wanting to terraform Mars, how about we terraform Earth instead?
Amazing video
That 150k doesn't sound affordable to me.
Great video though!
So where's the insulation?
More 3d printed houses? Heck yeah🤚🏻. Use your sexy nerd powers to get a concrete house printer!
