When the print head didn't Z-hop during the non-print move @1:13, I nearly had a heart attack because that's the leading cause of print failures in my farm. Nice video, amazing machine!
@Dayne Littlewood Sure Dayne, and how many building sites have you worked on? So this machine will operate in freezing to tropical environments, steep slopes, muddy and boggy sites. Has self set up capability, self cleaning, maintenance. It's a refined version of a concrete pump, with 10 times the moving parts. If it's going to go and play on a building sites... time after time after time, it probably needs to be more resilient. I've seen some truly great innovations of tech and useful products introduced into the building game through the years. The trash heap though is way higher than the treasure heap..... Yet I spose, research and development is an important part. It doesn't matter if there is a viable outcome, or not. It keeps people employed and off the streets. And I just love all these 3D videos claiming houses built in days, hours, since when are just the walls a home?
Андрей, я ждал ваше видео много-много лет. Технологиям строительства, которым многие сотни и тысячи лет, пришли на смену новые, скоростные. Благодаря таким людям, как вы, проблема с дешёвым и доступным жильём практически решена. Спасибо за вашу работу!
Wow, all you haters, hating so much. This is a great technology and I'm sure it can be made to be as strong, probably stronger than any existing building technologies. This type of technology IS the future, like it or not.
That's a pretty thin wall with no internal lettuce. They are getting very very good with the concrete mixture and printing process for this not to fall or slump over! I just love innovation! Fill those walls with some foam crete and that could be a carbon-negative house. feeding energy back to the gride that it's creating but not using itself.
+MCGamingBrothers, yeah it was somewhat dishonest but still striking. It tells a clear story about the future of construction. Although it wont use cement.
How can this be hurricane and tornado resistant? Where is the structure of the house? The horizontally printed layers can be broken and demolished at one simple push! So, in what consists the resistance of this system? Thanks.
+Teodor Miroslav Muntean only reason I clicked on the link was to see that - the printing is way cool but I wouldn't want to be in one of these during a hail storm in Oklahoma
Yes, Jim, I guess so :) We have the same problem in Romania, where the earthquakes are very strong sometimes! However, I am looking for solutions. I came from Romania to Atlanta, GA, and doing some research in construction and real estate field, including 3D printed homes. I think there are solutions but all developers are only pioneering yet in this field.
For structural integrity, most 3d printed homes I've seen include: the outer wall; the inner wall; and a wave form between them, connecting the two outer shells, and providing lateral strength. Empty spaces between forms usually filled with PU foam insulation or structural PUSS foam. The foam is usually emplaced after utilities are installed, and before the top of the concrete form is capped. I've also seen some constructions that include a waterproofing layer placed on the form exterior, as an added protective measure in high rainfall/humidity areas.
Very impressive. You gotta admit though: The "traditional" approach is 8 guys working with no modern construction equipment at all, you can pour concrete directly from the truck at high speeds and you can get a decent crane in order to have all the bricks where you need them... You did pick an extreme case here ;)
The 3D concrete tehnology is at beginning ! At the moment it can be built very limited type of houses, like shelters for non seismic areas. There is a computerized concrete cast without bar reinforcement, so a real house, with a foundation and using reinforcement bars, cannot be built at this moment with this tehnology.
This isn't true anymore. I spoke to one of the people demoing a unit at a tradeshow here in Las Vegas and he said rebar reinforcing works almost the same way it does in normal homes. You build your slab and have your steel coming up. At various points during the print, you stop it, place your steel where it is needed and tie it in. Then resume the print. And, because walls are printed, you insert reinforcing ties all over the place to tie walls together. Really, the biggest thing lagging is permitting and appropriate testing for building codes.
I'm actually optimistic with the possibilities of this technology, and i'm miserable gloomy prick. Affordable housing is big issue in this day an age, this technology could begin to ease the problem. Subscribed.
+artie ny83 plus, once it becomes more common, the printer would cost less than 3000$ to build (for a 98ftx18ftx38ft or ~30mx6mx10m) , and you borrow the print head, control, and motor assembly for maybe another 1000-2000$ , add 1000-2000$ of concrete and 1000-1500$ of reinforcement steel, and you have a home for less than 10k$ in a few years.
I highly doubt your cost estimate for the print assembly. As it stands, from the website of the creator of this particular machine, the basic model is $300,000.
It would be so easy for those in this business to simply be able to supply a funnel with potable concrete and to push said funnel along rollers to guide it reducing the need to be computerized but just gently by human power keep the funnel supplied with concrete and follow the outline of the house and raising with each pass till you've reached the height one wished all the while another funnel building interior walls. We should call it the "funnel method" of building sturdy homes.
Что на счет многоэтажного строительства? за счет расширения несущих стен? возможно ли прорисовка своего рода перемычек внутри стен для закладки допустим арматуры?
that would all depend on how big the print was. How long it takes to print a single layer measured against standard concrete curing time and work ability.
I bet the cost for concrete would not be anywhere close to the cost for labor and all other waste materials involved in building rafters, supports, etc.
Apparently, we're already at 20% to 45% cheaper per square foot with 3D-printed housing for the same square feet, but they need to scale it up a lot concerning the size of their business operations before it can become commonplace.
думаю будет лучше, чем если стукнуть со всей дури по большинству частных домов в штатах. они там практически все из дерева. а тут все таки бетон.. плюс стенки полые которые также можно залить бетоном или еще чем. будет покрепче.
Hello Andrey, I would like to do a story about your 3D concrete printer, would you mind if I use some of your video footage as the backdrop to my narration, in return for promoting your channel & video in the credits of my video.
I want more info on this. Just to clarify, it took only 48 hours of printing to make that structure? That's impressive! What does the 3D printer structure itself look like? Is it really tornado/earthquake resistant? I really like this idea if it's this practical.
+JandCandO There is more info on his company website listed above, "Print speed: of a 100 sq. meter house with a height of 3 meters is 48 hours." This is about 1000sqft house with walls of 10ft.
Ben Lavallee: Forget it! This is not for those whose minds generate questions. This is advertising. It takes people who are already stupid and makes them stupider at the same time that it charges them for it!
У меня вопрос, а надежность такого дома? ведь там отсутствуют вроде как железные основы которые нужны для "крепкости" и устойчивости конструкции перед внешними факторами которые могут разрушить строение. Или в смесь добавляется, что то особое, укрепляющие.
+Алекс Миротворец Вроде как видно на фото закладку арматурной конструкции и заливки бетона в полость стен... По крайней мере это вполне возможно. 2 Андрей - в каких климатических зонах пробовали стороить? В "холодных" - как сделать стены "тёплыми"?
interesting and great technology but I suggest you either remove the "Comparison" near the end, OR add a construction TIME for the manual labor house like you did for the 3D printed house. It is extremely bad communication when you use the world's OLDEST technology (people carrying buckets of concrete) to show how great your new technology is. It gives the impression that your technology may be better than "BUCKETS" but could not compare to standard PUMPED concrete or SHOT-CRETE. (spray concrete). I think your cool looking setup would have a hard time beating Shot Crete.
Андрей, технология у вас будущего! Вопрос к материалу: какая толщина вашего материала для московского региона (газобетонные 300 мм блоки приходится утеплять).
+Bruce Lunde I would be more concerned about the complete lack of any kind of reinforcement in the grout. I could not call what they were pouring concrete in good conscience. As concrete implies substantial aggregate materials in the mix.
AlanRLight This is what a real concrete form looks like www.cfemn.com/images/steelply2.jpg Bit of a difference between that, and anything I saw in that video. People who like 3D printed concrete usually don't know the first thing about concrete work themselves.
The "traditional method" showed in video seems really traditional. It's not how we build houses in Sweden atleast 😜. Most houses here are premade blocks from factory, takes about one day to put together at construction site. Still really like the printing way, looks cheap! Whats the difference in costs?
I think it's way more expensive because this concrete block has no reinforcement so it's quite weak you have to add lots of stuff to make it tornado proof
по клипу сложно понять крепость стены. если можно , выложите видео удара по готовой стене кувалдой к примеру... также установка кровельных перекрытий интересна
Андрей, приветствую! Отличное дело, но смущает, то что конструкция выглядит не очень надёжно, при нагрузке перпендикулярно стене. Рассматривали ли вы вариант с структурным (возможно оптимально сотовым) заполнением пространства между стенами? Судя по всему сама головка вашего аппарата может выдать короткие порции раствора.
We all know that this day was coming that 3D Printing will replace a lot of men/women in construction, just as electric cars will put a lot of automotive technicians out of jobs. Do not blame technology people just must prepare for it, the warning signs are around many and they just wish not act upon them.

Господи, как же это круто!
I believe uses premixed concrete with an adhesive which keeps the mixture semi wet for a long period of time and printing speed kept lower 30 mm/s.
I know China has been experimenting with 3d printed housing (strictly in a utilitarian way) for a couple of years, But this is a huge leap forward!!
This is what should be built in places like Florida and the gulf areas!

If i owned one of these, my first priority would be to print an upside-down house :-)

+MCGamingBrothers, yeah it was somewhat dishonest but still striking.

czcams.com/video/nH-zpnoNLEU/video.html
They cant do that...it's twice the size of the house.
The whole printer is basically just a 2-axis gantry crane.
Also show the loading of materials - how does it convert dry mix into the extruded slurry?
can styrofoam beads and waterproofing platicisers be added to concrete mix?. this waterproofs mix and lightens concrete and makes it stronger
How do you slove problem of static forces...It seems rigid, how it acts in case of earthquaqes
How can this be hurricane and tornado resistant? Where is the structure of the house? The horizontally printed layers can be broken and demolished at one simple push! So, in what consists the resistance of this system? Thanks.

+Teodor Miroslav Muntean The walls are hollow. Simply pour concrete in there after the printing is done.
+altaroffire56 Is not that simple... we need to introduce rebars there, many of reinforced bars as calculated by the structure engineer...

Здравствуйте, Андрей! Восхищаюсь вашей работой! Скажите, какие программы используете для проектирования и расчета конструкций?
Could you have workers with trowels smooth out the concrete while it's being printed?
You just plaster over it after it drys.

What material are they using for construction 🧐 it's not clay right??
