![Are Piston Coatings Worth Having AND Can Coatings Save Your Engine? [TECH TALK]](http://i.ytimg.com/vi/1MZZrCWqWm4/mqdefault.jpg)
Well....Mind. Blown. I had no idea we were so far down the road of 3D printing to be able to produce such high stress components!
Airbus wants to produce titanium landing gears in future with 3D printing, and other aircraft parts.
spacex rocket engines are 3d printed
The strength of SLM printed parts actually match or even go beyond that of cast metal. If done properly, and with proper post-processing, porosity in parts can be eliminated and crystal structures can be improved. The true benefits of 3D printing lies in geometries hard to produce using traditional techniques though. Like topology optimizations and internal cooling channels shown in the vid
Ralph111417 I study mechanical engineering and me neither 😅
@@cucumberworks I think the integrated oil channel in the piston would be impossible to construct using normal manufacturing. Very interesting to see them really take advantage of this technology.
So that's how one pronounces Mahle, thanks.
Lol I was thinking the same thing , Ive avoided saying their name before cause wasn't sure how to pronounce it properly
I am with you! I have been pronouncing it “maa lee”.
Just learn the language 😉
I always pronounced it same as Maler (painter)
Right?
Everyone around here pronounces it "Molly."
Now lets keep a complete inventory of all car parts so we can print them 50 years from now.
This man here speaking the truth
Not enough though, you only produce the blank by 3D printing which on it's own is kind of useless. It's not a finished part ready to install. The thing is, once a factory ends production of something, that thing can never be built exactly the same way again, that particular set of machinery and processes will never come together again. It's why more Saturn V rockets or Ford Model T cars can never be made again. You can dig up the design files and build a replica based on them, but that's all it will be, a replica, not continued production of the same thing. Because the manufacturing process will not be the same as it used to be, the tooling will not be the same, the work methods will not be the same. Heck even the materials might end up not being quite the same. For example, for sure somewhere there is a drawing of a Model T wheel and it might even say to make it out of wood, dimension it such and such, but I bet the decision on what kind of wood to use is left to the reader.
@@aleksandersuur9475 You have based your answer on making exact parts. What wrong with quality replica parts if it means putting your car back on the road? Better than not having the part at all.
@@dan__________________ Fair enough, if you want to make a replica then having the original design drawings or CAD files would be incredibly useful. But... well it's not like archives of these drawings and designs haven't existed for the past century and more, every manufacturer archives all the designs they have ever built, in many countries you are legally required to keep them in fact. Unfortunately them having the archives and you accessing them are two different things. In the end I think you'll just end up doing what everyone always does in this situation, take the dimensions of the broken parts you have and design your own generic replacements.
3D printing is taking over the manufacturing in every industry.
Great for efficiency.
I wouldn´t say taking over but it is added more and more into the development and production of all kinds of products.
@apSos.de it's actually not great for efficiency compared to casting, forging, billet machining, however it does enable features to be produced that might otherwise prove difficult or impossible, such as the cooling channel at 1:31
World produces about 90 million cars per year. And it takes 12h for a 3D printer to make a set of aluminum piston blanks for one car. So to make all the piston blanks by 3D printing, you need 123 288 of such 3D printers working round the clock just on that and nothing else. These 3D printers cost about a million, but I'm sure you can get a discount on such a volume, so lets say you can get away with about 100 billion investment in 3D printers and you got the piston blanks needed for world production of cars covered. You better not want any other part of the car to be 3D printed. The good, the bad and the ugly of 3D printing is that it does not do economies of scale, the first unit 3D printed costs just as much as the millionth. That's great if one is all you want, it's a complete deal breaker if you want million units.
It offers great opportunities to consumers to produce their own custom parts at home or in specialized Local Shops which specialize in 3D printing.
I have some obscure old Cars and Bikes, and 3D Prining would allow me to reproduce old Cast Parts that have been out of Production for years.
Amazing work. Opens up so many possibilities for the aftermarket and boutique OEMs.
I work for trumpf, so cool to see our tech working to make great cars even better!
Eye-catching designs. Lovely
Wow this is some impressive work 👏
Amazing technology. I gad no idea that Mahle could print high performance pistons like this.
They 3d print the pistons in Ferrari F1 engine
These are not high performance pistons they are used for prototyping, the title is a bit click bait.
@@Iseenoobpeoples well its not because its highly likely to be the way they produce low production volume pistons from now on. What would be the point in prototyping a cooling channel inside the 3d printed piston, when it cant be reproduced by any other means of piston manufacture?
There is a company in greece that makes real 3d printed High performance pistons that can withstand 2000 hp plus while also beeing 50% lighter than a normal piston
Up next, airframe and sensors integrated systems for aerospace...this is an exciting time for technology
It would be amazing if Porsche made a limited edition Porsche that would push the limits of 3d printer technology
Stunning
La più bella e affascinante di tutte❤❤❤💪
Best brand. That's what i use on my VW
bugs and buses. 1600cc and 1776cc.
That’s the same brand on my Stihl chainsaws!!
A lot of those Mahle piston sets are made in Brazil or Mexico, hard to find a good German set.
Wow , just wow
Exciting and amazing technology! Can’t wait for it to trickle down into a car I can afford 😅
Sweetness
Does the wrist pin journal have to be of equal dimemsion all around? It's only pulling a partial vacuum on intake, so could be thinner on the crank facing side.
very cool
Could the same technology be used to make sleeve valve pistons with the same efficiency as poppet valves?
Some informations about the manufacturing time of an 3D printed piston vs the manufacturing time of an conventional pistion would be interesting!
Is it possible for a volumen production?
Porsche only made 500 GT2 RS's globally, and they go for $294K apiece. Now Do you think they are concerned about Mass production?
12h For a batch of 5 pistons. One of those machines probably costs just as much as a GT2 RS if not more. I don't think we will be seeing these pistons in any mainstream vehicles any time soon.
@@treffle17 one of those machines costs just as much as a GT2 RS? Not even close, try 100 of them.
@@treffle17 honestly I could see VAG using this in their mainstream cars in the next ten years but that's only of they aren't forced to only produce electric vehicles before then. With how much 3D printing has improved over the past few years I don't see why they wouldn't, less material loss , better end product and 3D printing is getting faster everyday 12 hours for 5 today but 500 in less than 12 hours tomorrow kinda thing.
@@joshmac7245 Yeah but although topology and the cooling gallery are nice for high performance applications, by far the most engines aren't built for peak performance, therefore they'll still get cast pistons because they are way cheaper and faster to produce
@@FzudemB though I agree with you for now , down the road that will change. Just look at how far 3d printing has come in the past 5 years. I think the only real question is "will the combustion engine still be around when that happens?"
Imagine in a few decades when these are affordable like plastic 3D printers today 👀
Can you 3d print enigine and gearbox?
Good work germany I admire your engenniering, I would like to move stuttgart
Where would you move Stuttgart to? I kinda like it where it is...
@@Penguin_of_Death move to stuttgart sorry, or Múnich beatiful cities proper for study, and a little bit expensive, I would like to meet more the german culture, I was in germany 1 month and I love it
I loved short visiting Munich and Stuttgart. I really love this parts of Germany.
Stuttgart is hell of a ugly city. At least down in the cettle of the city. I would recommend munich, Freiburg, Karlsruhe or Konstanz way more.
@@sebastiancv4595 don't go to South Germany. The North is a way nicer place to be and people are more open
Titanium piston bearing ?
Very interesting! Just came across this video. We have developed new meta-technologies that could revolutionize this component and others. I will contact. Thanks to the OP for this video.
I’ll take a set for my SBC 383 in my UMP Dirt Modified 😋
Ferrari could need this at the moment 😂
They already do in their f1 engine
No. They need purchase the F1 car from Mercedes fews year ago.
Nico S. Won't keep them from catching on fire
i thought they were expirmenting with forged carbon pistons and rods
They need good aerodynamics.
now couple the 3d mechanics with artificial inteligence to make an ultimate piston that ran in an virtual engine to perfection via generations of test
That's basically what they are doing. It's called generative design. You give the computer the base parameters and it creates the perfect stucture iterativly
Any news about this?
These pistons would completely change how engines are made.
Super fantastic
Ill buy a set for my BMW
Hello Türkiye İstanbul video süper tankyou
Oil cooling has been used in pistons for about 20 years now. Why is this method better? Why not just CNC from a forged material?
You can't integrate it in the same way. When you look at the graphic, how should it be possible to machine a full circle which is enclosed.
@Flying RC how would you produce the cooling channel close to the piston crown? See 1:31
Oil cooling is even older than 20 years in gasoline engines. The Nissan 300ZXTT was introduced in 1989 and had it. I think the Nissan 300ZXT had it in 1984. Also, some diesels had it even earlier than that. I think some Benz diesels got it in the 1970s.
The difference mentioned is that 3d printing enables more flexibility in oil channel design when compared to existing methods.
@@skylinefever The RB engines in skylines also had them in 1989. My point is this 3d printing method adds no benefit when a 1000++bhp engine runs forged CNC pistons that's already proven technology.
What is the price for this position in Euro ? And where can I get it in Germany ?
3d printed pistons or forged pistons, which one's better? Both are quite different imo. Please lemme know.
That's an interesting question, I'd like to hear the answer too.
Based on pure speculation and my 'midwit' knowledge of materials, I imagine they'd be able to control the grain structure of the 3d printed piston and do some post-printing heat treatment etcetera to get the strength and where it needs to be. However, I would have still thought a forged piston would have a better grain structure as it's more homogeneous and therefore it'd be stronger?
@@zeroyon4562 yeah i was thinking the same thing, i was like maybe they could reinforce a piston with a 3d print manufacturing process cuz with a 3d printer arguably has say more flexibility in the process, make sense? Idk. But forging is a much more complex technique requires a metal to be beaten down repeatedly to cover any air pockets and usually results in a much more robust product.
I just cant pick a winner.😂
Now I just need to somehow get a job working for a co like that.... #Dreamjob
This piston and parts manufacturer is second to none in the automotive industry and also developed the coatings on rotors of the wankel rotary engine in 1965 ,pistons for all generation Duramax diesel, powerstroke diesel and LS, coyote and all your favorite engines car people love and many many more. Also makes some of the best high performance forged pistons money can buy ,I only use mahle gaskets when available i dont have to worry about them leaking months down the road like Felpro's made in china crap.
But only has 10.6k subscribers!!!!! :(
Actually... second to almost any electric motor
@Bernd DasBrot nah
... So I should use Mahle oil filters on my VW?... 😁
I have them in my cars for years.
yeah, theyre truly good filters and generally not that expensive
1:53 how the buttplug came in the printer?
wait on demand Hmmm I'll send ya a CAD file off my piston, would you mind optimizing it ?
I can, send me your cad file
Stuttgart facility?
I’m a bit lost. Isn’t this just a lathe? It seems there is a thin line between 3d printing and manufacturing.
The machining is just for the finishing touches like turning the outer surface and probably drilling the hole for the wrist pin. 3D printing can't achieve the tolerances needed here.
Seems like a very premium item for the time being with the amout of time it takes to make only one product. 3D printing has a waste potential for amazing products, but it's not cost effective for mass production yet sadly
Naja aber nacharbeiten muss man trotzdem noch. Die SLS sind leider noch nicht sehr genau. So groß sind die Vorteile folglich noch nicht
Make some 3D printed pistons for Forward Auto Drift Team 🔥
on the other hand the same group member vw still struggles in piston breaking issues by conventional production...
German Engineering at its best!!
Them German!
Amazing, but isn't this too late? Everyone is focusing on electric and alternative energy and Mahle is producing new concepts for old technology.
This is for high end performance cars. Battery electric vehicles are still way more expensive than a good old ICE, and even Tesla's charging network is not yet comparable with gas stations in capacity and charging speed. BEV does have a few specific advantages over ICE, but also several major drawbacks. With a plug-in hybrid you get most of the best of both worlds and you don't need to pay for that expensive battery. ICE is far from dead.
Самый важный параметр это Срок Службы!
Биалите на Поршето издържат 50 хилиляди километра на писта на 100% натоварване. Тези буталата са изчислени да издържат също толкова. Ако пистата е дълга ~5км това са ~10000 обиколки. За 10000 обиколки шасито отдавна вече ще става само за скрап заради умората на метала около заварките.
NE tut govoritsya chto eto prototype srok sluzbi nevazen oni testyat naskoko hrenovim mozno delaty porshni shtobi oni sgorali primerno posle garantii ))))))
They make the blanks in batches of 5. Awwwww crap. Gotta make another batch.
Their Ecoboost 2.0 Forged pistons need work. Wrist pin end play and oil ring design are troublesome.
Thats a failure from Ford. Mahle makes only the part from the dates of Ford. So tell that Ford.
@@Cupra317hp the factory pistons have good end play and the oil ring doesn't fold over when you're trying to install the piston. I was unable to install both c clips on the mahle forged piston. I had to shorten the mahle wrist pins. It's not an exact copy of the ford cast piece.
I love the new AI powered evolved machinery.
Can German engineers and scientists not look like Bond villains or is it genetic?
But metal printed one always be softer and more fragile no ?
I think the secret is in the sauce... AKA.. the powder they build with... Classic SLM printing is not good... but they said they have a special self developed powder.... interesting..
@@steinarne79 I was wondering about the long term durability of these pistons. I'd seen somewhere that 3d printed metal parts are more prone to failure because of material used. I think the process leaves parts with more impurities that can make the parts prone to micro fractures.
@@KhushbuMel How long term are you talking about? 2-3 years or 10-20 years.

So how much is 1 piston about. $10,000 a piece 🙄
These are not high performance pistons they are used for prototyping only, the title can be misleading.
true video don't say about flaws of that kind of piston it never be capable to compete whit solid build ones i bet its 3d manufactures want get some investors to justify having mega expensive 3d printed pistons )))
Are you suggesting 3d printed piston's can't produce high performance?
@@mrcat1991 Alternatives are much stronger/reliable, that's why they are used only for quick prototyping/testing.
@@salamdrik At least they mention prototyping in the video unlike HRE wheels that try to scam people by saying their printed wheels is just as strong.
@@mrcat1991 forging makes usually stronger parts than casting, and 3D printing is from the principle similar to a casted part.
On the other hand, you can produce parts which have a different structure inside the material than ouside (and imitate biological structures like bones) - this is something only 3D printing can do
Like nothing else
Basic engineering
Are those dish pistons, do you even know what you're doing, lol. Just playing.

What bs! Same design can be still be made by forging. This video is just a lame PR stunt 🤣
Could you do the water channel with forging. I'm betting you can do more with a 3d printer than forging.
electron Jarvs if anything that’s designed to flow through, it can be done via the casting/forging process. If any hollow space needs to made inside the structure then 3D printer can help. I personally design and work with 3D printers at work. The only key point is for 3D printers shown here is small batch manufacturing which wouldn’t be ideal for forging. The start of the video is just marketing BS.
Electric cars don't have pistons lol
Nice Paper weights. That looks like a very expensive toy.
6th cylinder, intermediate shaft, 3D printer without solving the problem? Don't make me laugh.
So, basically, stone age technology. Cool.
I'll stick with modern technology witj greater performance and efficiency, such as the electric motor/Tesla. Thanks.
That is modern technology you‘re seeing here and I’m sure it will be used in your beloved EVs very soon. Not for pistons, but there’s still a lot of classic engineering going on. Maybe not with Tesla, but other manufacturers. Be open for new inventions in every aspect of mobility and stop being a narrowminded Tesla-fanboy with no clue of rational evaluation. EVs and combustion engines each have their own advantages and disadvantages. But some might prefer a classic mechanical watch instead of some Apple-watch, if you understand what I mean.
@@ar_pe4012 lol. Name one advantage of a caveman combustion engine?
Haliotro range, especially when you live in Germany where you can easily go an average of 160km/h on the autobahn. Higher top speed efficiency. And where does your electricity come from? Love and Happiness? As long as it’s based on fossil energies, don’t say evs have zero emissions. Weight (sportiness). Less emissions in production, and no exploitation of rare earths in 3rd world countries. And for some enthusiast engine sound might be very important. I don’t doubt that electric motors are the future, but for know it’s not better without exception. Get your facts clear and stop thinking one way. And even if some inventions like combustion engines are not always up to date, they still are marvels of engineering and one should respect it. I wonder what amazing inventions you had...
@@ar_pe4012 I'm sorry, but EV using fossil produced electricity is still way more efficient and produces less carbon than a combustion engine
@@ar_pe4012 lmao i never said they weren't marvels of engineering. That doesn't make them favorable to electric engines though.
