3D Printed Concrete House, Printed in 48 hours 

The speed is incredible! It seems less like "building" and more like "growing" a house.

This is most definitely one of the futures in home building. Lumber prices and labor cost is astronomical so like anything else, automation is a huge benefit. Combined with computer perfection, its how I would choose to build and develop.

That's simply amazing. At the beginning I thought it was going to be a scale model, but it's the real thing - a full size house.

I obviously need to read more about these, but can’t believe these would be approved by code without a steel skeleton for structural integrity! Especially in an area prone to earthquakes!

This is extremely cool tech, but realistically all that I see being done here is framing and interior walls. Is it also installing electrical, plumbing, heating/cooling, insulation, roofing, doors, windows, cabinets and finishing walls and floors? Anyone that has ever built a house knows that this is where 90%+ of the final cost comes from. That is also the part that takes months and months to do. I also don't see any rebar put in that concrete. Concrete without rebar is extremely brittle and can be easily broken. Like I said, very cool tech. I would personally let this one sit in the oven for a decade or so before I would look into it for my home.

Would it kill them to add a scraper wheel that smooths out the layerlines?

I can’t wait to build my cheap house on my $2 million dollar block of land in Sydney🙄

Just stacking layers of concrete on top of each other without steel reinforcement, I dont know how sturdy the walls are going to be !!!

In 1980s in Soviet Union countries when there were not enough apartments for people, they started casting walls, ceilings and floors in dedicated "house factories", then they transported them to the building site and they were building block of flats like house of cards. There are still a lot of these buildings, they are easily recognizable by the fact that they are identical to each other. The approach was different, but the goal was the same: build faster and cheaper.

Fast and cheap. Will probably fall apart due to lack of flexibility, crack and wither during winter times even faster. Wood, metal or even plastics are necessary in order for the house to flex, it needs to have some give, otherwise it'll just break. The concrete doesn't even have steel reinforcements for crying out loud. Plus, you still have to do all the wiring, plumbing, insulation, flooring, finishing, on and on. The skeleton of a home makes up a very small percentage of the total labor and materials.

What about plumbing and electrical? I’m curious on how that would take place without interior wood framing

Please bring this to South Africa Our need it asap

The foundations are good (even tho I think there should be something like pillars in the ground for more stability) but after that it'll be good to just use the concrete as bones and apply electrical wiring, outer isolation (since in winters this will be like living in a concrete (litteraly) box) and on the inner side it's better to make the walls or use drywall. Other than that the idea is awesome

Making houses cheaper to build won't lower the price; it will just make it more profitable for the people who CAN afford to buy houses.

I hope this catches on and makes housing more affordable in the future.

Something like that but with a flat concrete roof that’s also a balcony space could also be extremely resistant to most natural disasters! :)

This is amazingly beautiful. I'm now going to open a construction company. Building a house never been so easy.

Looks like a nice bungalow, and the speed is impressive. An issue is the massive land cost of bungalows, but I can see logistical problems with trying to engineer the system to produce three storey houses with a smaller footprint.

For those wondering about electricity installation, it's not a big problem. Walls are "empty". All you need to do is drill a small hole and install wires.

Fantastic idea! Rodent proof,insect proof all the insulation protected from external elements. No rebar is awesome. rebar has been shown to actually weaken because they rust and cause water channels. Many finishing possibilities great for tornado prone areas. Wiring and plumbing in the insulated cavity. Those who don’t see the advantages will soon be weened out of the building industry. Weenies as we call them. I have 30 years building with all types of construction materials in harsh winter climates and humid hot summers, concrete with fiber reinforcement (chopped up windmill blades and fiberglass boat hulls) is an extremely good material for residential and light commercial buildings. Plus i would get away from straight walls to improve air film and wind resistance. I see no problems.

Nowhere in this process did I see any rebar being installed, especially in the foundation where it is needed the most (That footing looked completely inadequate). You can't build a concrete structure without reinforcing it with rebar and expect it to last. Also you might be able to print the walls in 48 hours that's it, not the entire house. The rest of the house has to be built the traditional way, framing the roof, installing the electrical, etc. The concrete will also have to cure before installing a lot of these elements. A wood framing crew could easily stand the walls up on this house in one work day, that's in approximately 15% of the time it takes this machine to do it out of concrete. Concrete is also very unfriendly to the environment and is being phased out as a construction material. These machines will also be very unreliable and require a team of technicians to fix and maintain it constantly. They are also not including the time it takes to transport and set up machine which I would imagine would take quite a while. What do you do when you have to build multiple floors? Is the machine capable of this? What do you do with the machine while you are forming or framing the floors which take considerable time? Do you leave it there idle or bring it somewhere else and then bring it back? That seems like a huge waste of time. Can this machine work on a sloped/irregular surface? What happens if the house you want to build as larger than the machine is capable of? What happens when the elements affect the working conditions? If it is raining, too hot or too cold can this machine continue to work? If someone like me can find this many flaws (Give me a bit of time and I could find many more) in the system while having my morning coffee this system has a LONG way to go before it comes anywhere nearly as effective as traditional construction methods. This is nothing but a novelty and will end up costing far more and taking far longer than traditional construction methods. You might be able to make this system work on a subdivision where all of the houses are on flat ground and are all similar in design, that's it. Just my two cents:)

A great company I have even contacted them regarding investments. The demo house featured here in NY looks fabulous. With a Texas company ICON you should start really seeing these homes proliferate very soon.

Finally, they are using technology. It's amazing what a little push from nature can do to species of all kinds. Humanity has spent way too much time in a stagnant phase. Evolution doesn't happen unless our existence is at risk. Push forward, overcome obstacles with the tools you are given and in time you too will give back as well.

3d printing sure does have a future in this world.

Great video Wonder world! ☺️☺️

This is a great idea and will get people and there families off the street and into a substantial and Good standardized living environment

The problem is not the cost of building a home, but the cost of the land. For example, in Seattle, WA, a house can be sold for over a million dollars, but to rebuild the house from the ground up will be $400k. So the cost of labor is a fraction of the cost of land.

Concrete built houses have been around for decades. Icf is the most common and is capable of amazing architecture designs along with outstanding insulation.

Don't forget that after the 48 hours, it has to cure which takes 30-40 days and then you have to do all of the other stuff like plumbing, electrical, painting, windows etc.

3D printing affordable homes is awesome!! Now we need to include hempcrete to use us less sand etc

Imagine if you had 10 of these and you were in the uk building smaller homes that would be so cool to see a 3D printed terrace block

I like the utilitarian look, I want one.

Doesn't matter how easy it is to make it. That only means more profit for the developers.

I’d just use more concrete to mud-plaster the outside and you won’t be able to tell it was 3D printed! 🔥🔥 I love this!

Having a simple house is a dream these days for the middle and poor class. It used to be an achievable goal a while back. Not anymore. Enjoy your rented, room, apartments and cheap homes in bad neighborhoods.

I like it but just wonder about composite plastics instead of concrete ? It would be less apt to crack , flexible and would be warmer feeling in the winters. I have never been a big fan of concrete.

That beautifully inspiring music and all the jobs this will take when it comes around. Thus creating more ppl who have to look for more affordable housing bc they can't afford what's in the current market. Literally creating its own customers. Hope you all enjoy trying to run coax or electrical in the walls later on when you want to change something. Also hope you all enjoy the lack of rebar and it collapsing on your during an earthquake or hurricane. All very possible without proper structural designs not existing within it. This will not last and thankfully it won't. We need more jobs to fix poverty... Not less jobs and more affordable items that will become out of reach for those that lost their jobs. These companies are just looking to monopolize as many aspects of a home as possible and aren't concerned with the lives they hinder along the way.

I'm all for supporting this if it helps reduce house prices!

The print might take 48 hours but to set up and install everything it needs to live in is the true time it takes to build the house

That’s gonna be a strong house lol really strong

Its cool and all but concrete is not flexible i will se cracks in the walls in less than a month

My aunt LOST HER HOUSE IN THE FLOOD IN CANOAS/RS😢 she was so desperate, like so many other families in the south of Rio Grande do Sul! I wonder why the state and government don't partner with companies in the field, this type of house is ready in 48 hours. A revolutionary system! Please donate a house to my aunt. She's from Mathias Velho. At this moment, all companies in this segment can show this modernity and be the solution for the reconstruction of the state of southern Brazil. 🇧🇷 help her please 🙏🏻

Thats pretty cool tbh. Can be ran 24hrs a day too. And as for it looking layered on the outside you can always clad it to hide that or even render it. Inside will be plastered like you would now. Cracking idea tbh

I'm so impressed with this whole idea .

Sooo.. you're just not going to insulate it? Or.. install any electrics or water? When and how will that be installed?

This is awesome. Almost all of the things you feature I have never heard of before

Incredible they can do finish with Sanding and sculpting 🙂💔!

3D Printing has a bright future ahead

Well I'll be damned. I pass that first "shipping container home" daily.

This is going to crack and crumble in on itself without some sort of inner reinforcement like rebar. Very dangerous. Concrete is very strong but it is it's own worst enemy and needs a little help.

This head is ok but i have advice . Under the nozzle i would set material boundaries on both sides with small metal plates. These two plates must be raised by a relay when the robot deviates from a straight path. I have idea to upgrade this nozzle and results be a flat structures from both sides. Now the Layers have a uneven surface , not flat

The problem of those prices you mentioned is not high cost of the materials, but really high demand

Next up: A space-based 3D printer to print planets and moons! How cool is that?

Great just 48 hours, it took me 35 years

Cement needs sand, and the world is already facing a sand shortage. I think what we need to do is change our mind sets into not thinking we need such a large house on a large piece of land. Most of us just need 1/10th of an average house lot and use half that for a practical house.

I would be more impressed if you could get the building permits in 48 hours.

This is super cool. I wonder how much the concrete would affect chill in places like Pacific Northwest? Would it be like tile? I see how they kind of address it. Does drywall also act as an insulator?Instead of cool carpet on the floor, you could have cool carpet on the walls!

One could have a mixture of recycled materials and mixed with self insulating aircrete. Aircrete uses only half the cement even.

I like ur vids

holy crap, it's true, a fricking ROBOT BUILT MY CAR!!! (yours too, probably!)

Hopefully this will change the real estate market in the US soon. And people will stop living in cardboard boxes without soundproofing.

🤯 mind blown!!!

Wow this is really amazing

Looks like a game changer but I’m interested In the insulation. In terms of staying hot and cold how would that work with no extra wall layer? Also what’s the endurance like during hurricanes and tornadoes or big natural disasters

Kinda wish I had one of these printers at the moment :)

They just finished one right here in Williamsburg Virginia . I'm frantically searching for it's location , that how I ended up here ! Lol .

Yeah? What happens if there's any settling or the foundation shifts? I can't imagine that this will be any good in the long run. Have you ever had to deal with cracks in cement? It's like a crack in glass. It just keeps on spreading.

This could be a serious game changer for places that are prone to hurricanes and other disasters.

Maybe we can try another material, like the wooden powder or Agricultural waste to crash to the powder +glues

Literally I've been waiting for this since the day 3d printing came out, this is so cool that we're becoming so much stronger and smarter of a species by thinking like this (mattpatt's theory on tv food from Willie Wonka will be given form soon!!😂😂)

How about the electric wires , outlets, plumbing, lights ?

3D printers can build hurricane proof, fireproof, and flood proof homes for less than than the cost to build traditional homes. Plus they can doing it using local dirt/sand so it is leaving a low carbon imprint. Build enough of them and the cost keeps coming down, which means more affordable housing and less need for insurance. I don't know why the 3D printer business isn't booming?

When you're 23, trying to find a career path. Decide on becoming a builder and then see this video lol

Because of LYME mixed with water . HEMPCREAT is FIRE RESISTANT MOLD RESISTANT Good insulation and durable natural fiber.

Is there any Rebar in this entire place? there are 2 kinds of concrete, cracked and will crack.

Very cool 👍

Wonder what the environmental objection would be around the amount of concrete use (carbon footprint per job vs conventional methods)

half the price of regular house? I'd like to see the cost breakdown. This price tag would imply that building the walls accounts for more than half cost of the construction which is very doubtful. There's foundations (maybe these are not needed here?), roof, floors, plumbing, electrical wirings, windows, interior... I'm sure I didn't mention it all.

So the one rule of concrete is concrete cracks. How do you combat this in a 3D printed home?

I saw on the news that Habit Tat For Humanity had just finished a 3-D Printed Concrete House up in Virginia. I am wondering if a Mansion can be built using 3-D Printing?

It saves the BUILDERS MONEY. Not the buyers. There were several of these homes made in community in California and the starting price for the homes was well over $500,000 each. It's a real disappointment that this technology won't actually help families save money.

Hi There! Thanks for the cool video! 👍

be nice if they could print the roof , but theyd need supports , thats quite the overhang

No rebar or thermal break....

I love that it's concrete. Down with wooden houses.

That is very cool! I'm chuckling about the fascination with the flag though ;-)

Just think this could actually put a end to HOMELESSNESS !!!

houses do grow on trees! I told you mom!! Now please let me back in the house inthink I’m gonna have a heatstroke

If we make wooden molds and make a house from it and fill the molds with concrete, then what will that house look like?

I'm new to all of this and i'm confused about something. Why wouldn't these houses be 1/4th of the cost of a normal home? There is hardly any man hours, it just seems like he overhead would be WAY less. Are they charging for the convenience of speed? Why is it so expensive? Thanks

This would only be practical for arid locations. Concrete is such a porous material that it holds far too much water to be used for a home anywhere it rains heavily.

While I love this technology, it sure as hell isn't going to bring house prices down. The company that builds them will just make a larger profit when it sells. I live in Denver Colorado and the housing market is out of control, it's a sad state of affairs.

How do they put in rebar for horizontal wind loads?

Well the big bad wolf ain’t blowing that house down.

What about rebar?

What is it's thermal efficiency? "Ribbed look" looks nice when it's new and freshly painted but will be a nightmare to clean outside and will be a dust storage inside. What else...? Do you have any solution for reinforcing this construction? Is there any way of repairing or modifying the structure without compromising the integrity of the remaining walls? What's the cost analysis compared to traditional brick/airblock construction? What about the electrical installation and plumbing? Is it laid out when printing, is it easy to modify or does it lay outside of the construction? Is it only possible to have a single story or can it support multiple? Probably way more other questions left to address.

3d printed house : $2 million Regular house : $2.1 million Wow look at those savings

Interesting idea.

Like so many house building systems this concentrates on the walls of the building envelope but the walls of the building envelope aren't that expensive or time consuming or even complicated. I volunteered for a Habitat For Humanity project in high school and we propped up the walls of a house before lunch. 3d printers still don't do the electrical, plumbing, hvac, the roof or windows or site work. It's not going to print those beautiful epoxy floors. Wake me when it does the whole thing.
