- In Heidelberg, Europe's biggest 3D-printed building is under construction: using additive concrete. The pros: fewer workers are needed and the procedure is supposed to be more climate-friendly. Are 3D printers the construction workers of the future?

#housing #3dprinting
I hope someday they invent accessible prices for housing 😢
3D printed homes were covered by “the build show” recently with a bunch of homes built in Austin Tx. Depending on you definition of affordable, these were OK and highly efficient.
Great invention. Now good luck getting it past the interests of the construction industry, and planning industry, and local planners. $$$$
Oh and the banks. Everyone with a share in the present system will want to be paid for any change.
Well, that’s one of the points about 3D printing buildings in the first place. With increased numbers will lower the prices.
@@tedcrilly46It’s actually being done right now for domestic houses and seems to be going quite well.
@@danielwhyatt3278 depends on the country. try it in Ireland.
The construction gatekeepers will want their fee.
Pouring concrete into rebar reinforced frames would be faster than setting up and tearing down this elaborate printer.
can you create such parametric shape with reinforced frames?? At waht cost??
@@ugwuchikaeze8751 what benefit is there to the shape? its a feature with zero benefit!
And it would be much stronger. Maybe I missed it but I didn't see that they used anything to reinforce to concrete.
Exactly, a 3D-printed building is only inferior.
@@thebabbler8867 - you assume technology doesn't evolve...or that processes or procedures won't improve.
I like the idea of 3D printing of buildings and housing, as it has a lot of potential. My questions are with long-term maintenance, plumbing, electrical, upgrades, etc.
The answer is cracks...
@@MikeTsBees you’re wrong, I know your type, you rather live in paper houses.
@@outtersteller I live in a brick shithouse
Where you live is a choice. @@MikeTsBees
The answer is, you frame the inside after the 3d foundation is printed
Concrete production is an important CO2 contributor. This method needs tons of it, way mare than traditional methods.
Better use prefabricated elements: faster, less impact, cheaper.
I like this and I suppose that for colder climates this could be used to print all the way from foundations to external wall with cavities that could be filled with insulation. I also suppose that the printer could work around inserted door jambs and window frames.
At 3:21 in the video, on the left side of the image, there is a huge vertical crack in the wall closest to the camera. 😂
Isn't that just a shadow of a wire or something?
@@Yutani_CrayvenIt's a crack in the wall. Increase your video quality if you can't tell.
A few years ago I saw a 3Dprinter which built a house. That was amazing, but this is a new scale. Hope it works well.
This tech is interesting, but adoption seems to be slow. I remember watching a video on this over 10 years ago and it has yet to take off.
That was my first thought. It's probably much like the oil/ petrol industry that held back or lobbied against any advancement in technology or alternatives that disrupted their profits.
Always is slow so they can make their billions first
Maybe its expensive?
It's a case of flying cars
Because the powers that be don't want housing prices to go down.
Municipal governments, builders and contractors lobbyists, politicians.
That amount of concrete looks expensive, especially for an industrial building.
Concrete is cheap. Probably no different to a building made from precast panels as the labour and transport costs would be cheaper.
@@AORD72
Precast panels for industrial buildings?
For what reason?
Is cheaper, faster and lighter to use steel components.
@@argotcalo5575 Strength, endurance, noise dampening to name a few. Many reasons. Plenty of buildings being built out of precast concrete everyday for many reasons.
@@AORD72
For sure there are reasons to prefer precast concrete as a material.
But for industrial buildings strength, endurance and noise dampening can be achieve cheaper with steel components.
Forget about printed concrete.
@@argotcalo5575 "For sure there are reasons to prefer precast concrete as a material", and printed concrete can have advantages to precast. Like no need to transport and no moulds needed. Whats is the life cycle of a steel building compared to concrete? Steel often required maintenance due to oxidation.
BTW: There is no need for the ripple effect. You could scrape this flat right off the nozzle.
It just goes to show how little viable this thing still is. It's mostly just artsy fartsy. It makes no sense over prefab slabs + robotic assembly on site. Especially given the stringent criteria for concrete delivery and hardening.
that's what I was thinking
This would be best for a subdivision where they could pre fab with less material
We can do it with false wall work by POP and Alumnium channels.
It's just strictly not necessary to flatten the ripples. It doesn't offer structural benefit to flatten them but it would add cost. Much cheaper to leave it as is, or deal with it after the fact when you install insulation and finish on your interior, etc., if it's deemed too much of an eyesore to be worth the additional spending for the owner.
I can see an Architectural potential of splendor. I think it is not too much to later plaster the walls smooth (if needed). But those 'ripple effects' are truly remarkable. We can now for the first time make beautiful shaped curves with perfection.
What they do in the USA at least if they want smooth walls is the 3D printed concrete is still wet for a time, so they smooth it out like they would with any other concrete. So, add a 4th person to the crew with standard concrete smoothing tools and you have a smooth finish to the structure.
Here here. I look forward to see how these building do going forward with their owners and see how well they age. I would love to live in a house like this.
@@ChaJ67 but you need to be careful because that may affect the stability of the wall. Also you may just completely collapse it because the concrete doesn't have the structural stability yet to resist the forces applied.
@@Andreas-gh6is the way this is currently done seems to be perfectly fine and stable. Just don't down too many beers before getting started.
Maybe you could add a breathalyzer test for the person doing the finishing work so they are not too far above the legal limit if it becomes a problem. Also, unfortunately people with a severe case of Parkinsons cannot do the finishing work.
@@Andreas-gh6is I am just saying everything I have seen shows this to be a solved problem. I would recommend looking up some TH-cam videos of this being done in the USA. Time and time again I see them doing this for 3D printed homes and it works out just fine and looks good. Nothing falls over or anything. They just smooth it out and it looks nice and smooth and a perfectly safe structure to be in. It is just a finishing feature they advertise and the USA does have building codes and inspections and such, so I don't think they would advertise it if it lead to anything unsafe happening.
They also drop window frames into these homes as they 3D print it and it comes out fine.
The thing seems to be these homes are a lot quicker and cheaper to make while at the same time being more sturdy than what is usually built in the USA. The problem in "the heartland" are tornadoes, especially with global climate change making these tornado storms so much more frequent and intense, so they really need to ramp this up to build homes that can better withstand the next tornado to come roaring through after the current homes get wiped out. Especially with the lower cost to construction, maybe they can start replacing some of these mobile home parks that always get blown or washed away with much more sturdy and wind resistant concrete homes.
MORE HEMP!
We have very similar in the US. I wonder how seismically durable these structure are.
They don't seem to resist shear stress a lot with all those layers.
Glad to see this tech progressing and becoming more efficient. Hoping one day for continual full frame extrusion designs, that will be a game changer.
We know 3d house printing is potentially the future, but it has to be standardized industrial wide and if the technology is reliable and fast then it could be the main standard for house construction and perhaps apartment complexes too.
@@adagioforstrings007It doesn't need wood, only steel.
@@adagioforstrings007 Sorry I misunderstood you, I thought you meant support material. However it has shown in the video that it uses cement mixtures not wood.
It will be a case by case basis, for some areas it's ideal, others, it's really not.
I live in a cold area. I would want to fill cavity once cement is cured with closed cell foam for insulation. I assume in stages with height of building this is possible.
Yea, you could surely pour closed cell expanding foam in the cavity.
Wow I am impressed by the African brother
Six months to build the shell of a mid size building is awful. They still need to do floors, roof, insulation, all the mechanicals and electrical, not to mention finishing work.
What about rebar. What's the structural engineering stats for this 3D building.
What is bearing capacity of such walls without rebars? What will they do if there is a need for big openings for windows and doors? What will happen with the walls if they start to pour the walls during rain? Overall I feel that those 3D-printers will work only for small constructions with weird/unusual geometry.
Windows are not even that hard to do with this, just stop when the height is reached, then like wait a day, place something on top of windows to hold new concrete and continue. Other things solvable too.
Windows will make it more expensive which is why they're doing it without any
As a Building Scientist I can say the above responses are correct. As for load bearing and rebar - take a close look at the video. My guess is that they literally print out an open box section where the future column will be located. Once dry, they insert rebar and fill the box section with a stronger concrete (ie the box section becomes a formwork of sorts).
Pretty terrible. The reason this is ultimately so expensive and isnt catching on like you might expect, is because like the monolithic dome fad, you still end up doing traditional construction inside, to hold it up and create livable spaces. All they're really doing here, is creating a shell; like bricking the exterior of a house.

"Chikaeze Ugwu" is an awesome name for someone! Sounds dope
Thanks
is it Really that STRONG????
No😂😂😂
3D-printed buildings might go up faster, but with how thin, irregular, and poorly constructed those walls are it looks like it will come down faster too…
Ya there's no rhubarb in those wall's and I fail to see why it's better to layer it like poop instead of forming it into a strait wall.
They are sturdier than normal buildings - and yes you can build with bars.
The issue is however right now that they are limited to 2-3 floors at most.
@metallic… “normal buildings”
Nicely done, nobody can refute a nonsense description. Best way to argue. Not a good faith way of arguing, but a good way to claim victory.
It’s concrete bud ain’t nothing thin about it
Fantastic technology.
I hope that is possible for less carbon intensive materials instead of concrete. For the climate, concrete is not the future.
Yeah, those Romans really f'd up the planet when they invented the stuff... Give me a break!
Concrete is carbon neutral. What needs a lot of energy is to get it from it's natural state into cement form. But once you do that with green energy, the problem is solved. The cement will re-absorb the CO2 that was released during production while it cures.
No windows. So it's a big printed box.
You can build with windows. They just didn’t need any like many industrial buildings.
Windows are highly inefficient spots of of the building - so if you can omit them, you do.
6 months to build, and enough contracts for the next 2 years. So depending on the climate that's between 1 and 4 more jobs.
High price good profit...that's it..
It might look alright when plastered, even a tile pattern on the plaster, and painted. It should also be better used for foundational work.
This is a terrific application for this large 3d printer -a big shell with no windows or doors that needs to look interesting.
Everyone keeps asking if this will make housiing affordable. The answer is NO! This does nothing to make the land more affordable in the places where people want to be but can’t afford. Three expensive irreplacable guys and a giant expensive machine are no cheaper than the ten cheap guys that do conventional framework.
This does nothing to reduce the expensive and slow union plumbers, electricians,... etc. and the many government code inspectors that eliminate alternatives and keep prices high.
how much material it require and i dont think current construction material will be convinent
So the ripple walling and curved ends is to help the structure stand up straight and resist wind pressures? I can see it functioning in this form of enclosing a large space but it seems that the internal arrangement would be quite similar on complex buildings internally with requirements for fire and public escape.
Considering a conventional house can go from foundation-> framed-> roofed-> windows/doors-> MEKs rough-in a month or less I don’t see what advantage this has other than replacing skilled workers with corporate robot. Concrete has little to no insulating value and is very much NOT sustainable/renewable friendly so I’m sure the “answer” will be foam foam and more foam which is hazardous and energy intensive to manufacturer. This is like a shiny toy to distract from housing unaffordability whose primary barrier is in no way “speed” to build but zoning, regulatory capture, lack of skilled workers, and competition with private equity and the neo-liberal financialization of any/every economic asset to create rentier-only corporate capitalism.
So much concrete mix is being wasted, where are the bricks, God knows what kind of saving they are getting, madness.
Pre fabricated houses will always beat this for sure! And it's also better, since wood that has catched CO2 is stored in it. The problem with how we have built houses is that it wasn't efficient, but it can be.
Wow, impressive!
Square peg (server) for a round hole.
How durable are these 3D printed constructions? Feels like it wouldn't meet the safety standard guidelines..
Beautiful
Engineers call out vertical & horizontal steel rebar.
even if they speed up the process. the concrete is all setting at different rates. MIT recently did a new form of Liquid metal 3D printing that essentially printed into sand... maybe if they did the same here, but then I think you have all those disadvantages again.
could you do an update on this topic
Fine, but what if a part breaks down?
Oh man - very cool!
if i ever build a house it will be using this.
How would you install the windows, plumbing, electrical? How would you finish the curved walls inside and out?
Durability?
impressive style🦺
It would be easier if they manufactured walls in a factory 🏭 and assemble them on site
The cost of installation would be very high. Onsite construction for such a big building is cheaper and more environmental friendly. Imagine the emission from trucks moving from the manufacturing factory to the construction site.
Apart from concrete..which other material(s) can bring up such a structure
moons regolith is 3x harder than concrete if heated and compacted
just three people and the 50 needed to get everything on site.
There's difference between needing a team to assemble and disassemble everything and then let it run, and the need of a team to be there at all times, constructing everything.
Most of the square footage is in the walls.
Where’s the rebar?
As long as we recognize the realistic costs and benefits to this method, it can take its place as another construction tool. I actually rather like the look of the finished layers, but you also wouldn't want that look on every house. Very cool!
This looks like a concrete bunker style construction with load bearing walls. You may need to touch-up the walls with concrete or similar material on both sides to fill the gaps & raise a false wall to hide all the wires and pipes going through the building. Unlike brick walls the repairing & altering process can be difficult & unfamiliar to many traditional masons. These construction methods must be put to real-time use for at least 10 years to understand their pro's & cons.
it wil go with 3D scaner
So, basically they 3d print decking for monolithic building and then put metal in between 3d-printed walls and fill it in with concrete?
Can put windows the print will turn back on the window area. This also faster
Where is the Rebar? What about siezmic concerns?
Germany is known for its strong earthquakes.
I still don't understand how they meet tensile strength requirements and building code. If that wall were solid concrete, it would be required to be full of rebar.
I often wander how long it will be before we are able to print entire skyscrapers.
5 years
The sky is the limit!
This construction method is interesting but there is one issue...
Will a house made by 3D printing withstand a seismic event better or worse than a traditionally built house?
This will eliminate so many construction workers.
Mayhe not a bad thing for some areas
You have to build a building around the building you are printing it is a waste of money and in practical unless you are looking at off world production take it from a engineer it works in the same field
I never said I wanted a hornets nest for a house.
Where the bricks??
Short on sand?
Opening line "This Machine does the work of several workers" there goes jobs
🤔 so either they are laying concrete on top of dry concrete and layers won't stick together properly or they are pilling up wet concrete resulting drying difficulties and countless other problems in the long run! Also, it is very clear that they are using at least 30% extra concrete to do the same job! But I guess seeing as you don't need any builders, they are saving a fortune on salaries!
Als to make those wall esthetic and cleanable They will spend a fortune or never be able to keep place clean!
Awesome
interesting. but hetting the walls in place is the easy part. foundarions, water, sewage, electrics, heating, cooling, roof etc all adds time and is not automated correspondingly. getting the walls in place havent been the hard part in a long time.
No subtitles for that guy?
House dont have iron bar.??
No rebar ,.. good luck your going to need it .
The future of housing is people piling up in the existing homes because they are unaffordable
Price of concrete will just go up
Those 3D building very expensive actually.
It's the past, not the future. Though it can produce unique designs, it's not very cost-effective in competing with other building means.
Concrete building with no windows...in america we call those prisons...🤔
Very interesting!
Getting windows is no big problem. You can cut the wall and build a window. Simple.
A strong wind could destroy the building
Have they fixed all negative effects of 3D print building? Windows systems, humidity, water in general, isolation, other housing (water, electricity, heat pipes). Dusting, wall strength etc?
I use to see it as the future untill I met somebody with experience..... It change my view on the problem
it's been a year, has the building been completed? what does it look like? Is it durable ?>
The building has been completed and handed over to the Tenant. Currently they are installing the servers.
This might help here where there is a shortage of brickies and carpenters.
I think we have been here before with prefab building, most are condemned with subsidence and have problems with damp, for Africa maybe it's ok
Print-n-chill bro
Seam lines are a problem at any scale lol
Yes Ugwo go on dear. ❤
*Nigeria to the World!* 🇳🇬
When I hear "it needs few workers", it doesn't sound like an improvement
It definitely is the future of building a lot of stuff. There's no tools or assembly required when an object is 3D printed.

If that dude was from Canada they would not have specified that he "studied in Germany"
This design is good for outer space in moon and if for housing market let for get about it😅😅😅
Someday, tall buildings will be 3d printed.
No rebar?
Not needed in such a small building that is almost all concrete.
3 people yeah right no labors who installed those beams behind you.. cost of labor down and the foam house still cost to much 🤭
2,620,412.50 us dollars
How much will a tiny house made like this cost? $500,000 probably more.
I guess it is ok if you don't want windows, doors, or rebar
