@@samward2162 Cause the laser makes the grain structure of the metal jumble. Casting nowadays is done efficiently and doesn't have the same problems that it did back in the day. Hopefully 3d printing metal gets better.
Yeah, well, kinda. Most shows on youtube that are supposedly scientific basically don't tell you shit. Steph at least shows you the whole process of the build, which is great, but he doesn't show you the designs process, calculations, tuning, etc. The good thing is that this kind of content is understandable for everyone (even outsiders to tuning) and it's still nice to watch even if you're into tuning yourself. This is valuable content, I like it. But still I think he isn't sharing a lot of knowledge with us in terms of specific details. Why? Because I have seen how generously Russian youtubers share their knowledge. _"So I have ported the intake to 26mm diameter, at the valve guides it's 27mm, where the ports come together it's ported to 37mm, I only polished the top side because the bottom side has will have slow separation and therefore a rough surface is preferred"_
@@kiyoponnn It depends on your business model. And sharing info actually makes a ton of sense in quite some cases. If you are open and honest about your setup, then most people will think: _"hey, looks like you know what ya doing, can you tune my car"._ Such a honest approach and open attitude can bring in a lot of customers. In practise it's the charlatans and noobs who don't want anyone to see how they get their job done, because they're bad at it. And then there is the difference between knowing what should be done and actually having talent doing it. Telling someone how it should be done doesn't mean he will succeed. One great example of this in autosports is "Gocha", from the beginning of his career he has been sharing info about his setup _(including precise camber angles)_ with anyone that's interested, dozens of engineers from Europe and Japan have examined and photographed his car; and guess what: he became drifting world champion *again* in 2019.
@Kevin Schmidt can be done with any metal. titanium especially, because its so hard to machine or form, and an expensive materia to waste so much during subtractive manufacturing. its getting to the point where its gonna be cheaper to 3d print titanium and other exotic metals, rather than create a part out of billet via subtractive manufacturing
There's MarkForged, they use a different system and seems way faster and simpler than this. @Kevin Schmidt yes, for example markforged can print in a lot of different metals. Crazy stuff! [And no, I'm in no way affiliated with markforged, just like what they do]
koenigsegg has been printing some of the more exotic metals for a while now but im pretty sure in a different process. its rad to see this shit evolve!
this is actually a great way to give an even more prolonged life to old cars, make 3d print parts and then cast them into iron or aluminum or even steel
G.M. has been 3D printing of prototype intake manifolds since the 1980s. At that time I was an instructor at a local college and G.M. donated what was then called a stereo - lithography machine to the college. The media was a resin compound but worked well for prototyping low stress components.
An hr is a bit short for a custom part... Though this is not going to be its typical application... some of the aerospace stuff with titanium is stupid strong and you can do much more complicated inner shapes that are hard to replicate otherwise...
Stereolithography. Been doing plastics like that since 1986. That was even more complex: The laser focus was fixed right above the pool of resin and a bed would break the surface and get lased wherever it needed a build up. then it would lower 2-3mm and rise up again (minus the height of 1 layer) with a fresh layer of resin on top of the last layer...lase that layer...on and on and the machine would have to wait for any waves to stop in the tank so it was an overnight process for a few inches but you could build a furnished doll house a layer at a time. Now they are doing it with aluminum powder. That is some one off stuff right there as the cost to 3D print a form for a custom AL casting would be cheaper and maybe just as fast if you had the production nearby waiting for the part.
Your content is fantastic. Thank you so much for always being so concise and to the point. I find myself rewatching portions rather than skipping ahead like so many other videos.
If they ever come up with a high-speed version of this idea, say ten minutes per part, it'll revolutionize manufacturing as well as make it possible to keep any antique vehicle on the road.
I am so amazed at this kind of technology and this whole build that by the time the video ends I realize my my jaw has dropped and I need to close my mouth! So awesome! One of the many professional paths I wish I would have chosen!
@Lassi Kinnunen your first paragraph negates your last paragraph. Replacing pla with aluminium via casting reproduces the EXACT same shape as the pla part. If you printed it, you can cast it.
@Lassi Kinnunen but unfortunately aluminum does odd things when being cast into large and/or complex shapes. Would probably take several attempts to get the venting, sprues, and runners right. It's not always as easy as one might think.

Fun fact: I’m currently working on a project at my university that’s looking at speeding up the build time of those 3D printers by increasing the thickness of each layer. The only issue is that increasing the layer thickness could introduce porosity which would lead to mechanical deficiencies. It’s really cool and I’m really happy with the exposure this kind of printing has been getting recently.
The other issue is that increasing the layer thickness reduces your Z-axis resolution. It also slows down the process because you need to scan the laser more slowly to melt the increased volume.
In ceramic shell , some times we got porosity . You have so much time in the part , you try and save it . You can paint the runners inside with Devcon Liquid Aluminum Epoxy , never had a problem with it coming off , if applied to a new part .
What are the advantages? You still have to mill it so 5 axis machining one would have been faster and repeatable so what advantages are here? Does it develop smoother ports? Less turbulent airflow? For the price I do not get it but pretty cool process.
Impressive! I once interviewed for a company in Michigan that build parts using ultrasonic welding. The base material was a metal tape, I forgot what alloy. Around 2007.
Not sure if this was just an Austin Powers reference or if you really knew and was being ultra clever, but the unit that lays down the medium (whether metal or ink) is referred to as a print HEAD.
In 1976 A genius was born. Wrote the screenplay for Star Wars A few months later. It included music, designs of things like the Death Star, Millennium Falcon Etc. Most of the popular movies/T.V. series since are his. Apple, Tesla, Microsoft, videogame industry, Lockheed Martin, Ford, Toyota, Honda, Mazda, GM, Ferrari, Lamborghini, Keoningsegg, Pagani, Bugatti and many other companies have received his help. Currently has an anti-knock prototype that lets you advance ignition timing to most I.C.E. Can make his own drugs/medicine with the greatest of ease. With many other projects not being mentioned, are in the works.
It was by 1980 - I remember because I was working in the business hub of Toronto for a mining company that makes fine metal powders like nickel and cobalt for tech leaders like GE's jet engine division. In our office tower there was an architectural firm that was modeling proposed projects, i.e. those miniatures of office towers you'd see in lobbies. They had something that would lay a non-metallic powder and follow that with an adhesive to bond it where desired, then go up a level and repeat, etc. I thought it was a nutty way to make a model but who's to judge. That would be the grand daddy inception of powder deposition. Early 90's I paid $625 for a Creative Labs 3X speed CD writer to be able to tell customers we could burn CDs for them. Slow as molasses but the first on the block. I paid over $300 for my first DVD burner a few years later (~1995) and it wasn't even 5X write speed.
Casting iron technology is about 2400 years old, so you could say it took quite a while to get to todays casting quality. So relative to that 3D metal printing technology and quality is developing/progressing pretteh fast!
The process is DMLS, Direct Metal Laser Sintering and there is a thermal post cure to reduce internal stresses you did not show before support removal. Most excellent creation of a custom intake manifold, thanks for sharing.
No, it's not sintering anymore. More than a decade ago or so, 3D powder metal printers would rely on SLS, Selective Laser Sintering. With the advance of optics and increase in laser power machines moved to SLM, selective Laser Melting. As mentioned elsewhere, modern machines can still do sintering when porous parts are required (say, filters). The difference between sintering and melting is that with the former you don't exceed the melting temperature of the powder, the particles just get hot enough to soften and stick/fuse together. You can get up to about 95% density this way. With SLM it is possible to truly melt the powder and get to 99.95% density.
I find this utterly fascinating from a technical perspective. The ability to produce parts in this way will only be improved and refined as time goes by. Likewise, I expect new processes will come into being as new machines are developed. Thank you for this highly interesting and informative insight into printing components. Subscribed.
What is your evidence that it's weaker? SLS metal parts are similar in strength to billet. They're weaker than forged, but the process is much cheaper than forging and allows for significantly higher design complexity without an increase in cost. Sounds like you're pulling things out your ass to me.
@@Tristor86 first off cast parts are way cheaper then 3d printed. like WAY cheaper. and billet is way strong then cast or 3d printed. do you get all of your knoledge from rediulous youtube videos like this one?
michael provost: I’m an engineer and I fabricate parts for race cars. I know a thing or two, as does Papadakis Racing. Where are you getting your information about the strength of SLS? It’s not as strong as billet, but very close, and allows significantly more complex designs to be produced which is an acceptable trade off to improve packaging and efficiency.
@@Tristor86 if i hit a piece of billet aluminum with a hammer its going to dent a little, if i hit a piece of that with a hammer it breaks. yea you can make complex designs with it. that is the only advantage. maybe another 10 or 20 years the technology will catch up to the hype.
michael provost: You’re making claims not in evidence. What you said is not an accurate statement. I don’t have anymore time to waste replying to you. You don’t know what you’re talking about.
I am amazed at the level of high tech engineering needed for this project. This is literally design rocket science and I know what I'm talking about : I am an aerospace engineer
@@mrred1012 they did not use direct injection so injectors had no fuel flow = no cooling so they just melt and burn out, thats why its hard to install a LPG to direct injected engines
@Clifton Green that's really besides the point. I merely meant that it could be spent on upgraded direct injection technology. Which is going to be the future anyways. The only current obstacle is cleaning of the valves that port injection offers.
Wow, I have huge respect for your knowledge and capabilities. You are right up my alley as far as the quest for engine building and design knowledge through all types of racing and all types of engines. 1000bhp is a very impressive number for a production based motor. The only itch I have is with the amount of money that is invested to obtain these results. I am sure that with the considerable resources put at your disposal, similar results could be had with a lot of other production based engines from different manufacturers which sort of takes away some of the glory that Toyota or BMW would like to earn as a result of this build. With that being said, I will continue watching your videos with great admiration. Thank you.
It's way cheaper to just produce a few 1000 extra parts, and sell them, rather than printing every replacement part. Plus, as you saw in this video, they aren't ready to go out of the printer, they still need some machining.
It's a great manufacturing technology, but it isn't going to replace all others. Yes, you can make some incredible shapes and parts that would otherwise not be possible to build with 3D printing, but if you design for "standard" methods, they are often just faster and cheaper. Yes, 3d printing will get better, but so will every other manufacturing method.
We live in a world where we can 3D print things out of metal, yet some people still feel the need to police what other people do with their own bodies. Mind boggling.
Its amazing all the time and effort you guys are putting into this Bseries engine. In such a short period of time you have proven to some of the keyboard warriors that as time goes on products improve and you cant get stuck in the past. 2J/RB time is over like the push rod V8
those engines will always be legendary in their own right. gotta appreciate all technology for what it was at the time, not what it competes with today
Thanks PR for sharing your awesome video. Your quality of work is superior, you guys have set the bar on 2020 GR supra to another level. Looking forward to your next video
Any advantages over a lost wax casting? There are a few variations where a part master can be directly 3D printed (rapid wax) or a mold for wax parts can be 3D printed.
In this application maybe not a significant gain. The fundamental benefits of 3D printing is the ability to print parts that are physically impossible to machine otherwise (think of a complex lattice internal structure). Another benefit is the weight savings without a loss in structural integrity (maybe even an increase in structural integrity) that can be made from using clever designs such as the lattice structure.
"a cast piece" not "a casted piece" it's called sintering not "welding the powder together" this technique is referred to as "SLS" Selective Laser Sintering. You forgot to mention that the sintered piece is "baked" to strenghten the bonds of the sintered material. very enjoyable to see this content. Thank you for bringing it to us.
This is not Selective Laser Sintering. SLS was something of about a decade ago. Laser power has increased over the years, and so has the quality of the optics. The result is machines that really do Selective Laser Melting (SLM) to 99.95% volume density. Modern machines can still do SLS, if the specific goal is to make porous parts (say, filters) but all modern machines do SLM now. And that's really melting the powder at microscopic level, no need to sinter afterwards. (As an aside, there are also modern 3D printing techniques that do need de-binding and sintering, but those are called binder jetting, where powder is mixed with a plastic/wax/binder and then printed with an extrusion nozzle. The resulting part does need de-binding and sintering. But that's not SLS.)
For this part I understand it if you leave it as be, but for more structural or high load parts you would ideally want to 'cure' the part by subjecting it to isostatic high pressure and heat to consolidate the metal grain and force out any cavities between the metal welding patterns, right? For heat subjected objects these cavities could provide more insulation?
They have one of these at my uni, but they have titanium powder instead of aluminium. They make custom parts for commercial aircraft and 3d modelled titanium bone prostheses.
I’m currently learning autodesk inventor in high school right now. Hope to get really good at it one day, I’d love to cad model and CNC a functioning engine.
For drill guides I usually design them with press in bearings, for harder metals sometimes the drill will eat into the steel sleeves making them less accurate, but awesome video! what do you guys use to design the manifolds? Is there any sort of CFD calculations that dictate how they should be designed?
Impressive. I was watching with great interest as you tightened the fuel rail to the manifold. I wanted to see just how tight you were willing to go on this experimental part! I see that you didn't push it too far.
I totally want like a dozen Parts made in this machine for my L28et but I'm sure they would want some ridiculous amount of money. Super exciting to see technology come along maybe someday normal people can afford them.
Great process for a one off part. But traditional casting seems much more cost/time effective than a 52hour print time. Expecially if you ever need replacement in the future. And at a cost of 8,000? I wish the video compared the cost and time frame of other processes, either cast or hand bent tube and welded. If you can drill a fuel injector mount, can it be welded on like an exhaust o2 bung? Edit: I know someone will say about flow, better flow always results in more power but the gains are much less on the boost side.
How much does it cost? About $800 per pound. So a 10 LB part would cost $8,000! What would you want to print out of metal?

Lol

The process is DMLS, Direct Metal Laser Sintering and there is a thermal post cure to reduce internal stresses you did not show before support removal. Most excellent creation of a custom intake manifold, thanks for sharing.
No, it's not sintering anymore. More than a decade ago or so, 3D powder metal printers would rely on SLS, Selective Laser Sintering. With the advance of optics and increase in laser power machines moved to SLM, selective Laser Melting. As mentioned elsewhere, modern machines can still do sintering when porous parts are required (say, filters).
The difference between sintering and melting is that with the former you don't exceed the melting temperature of the powder, the particles just get hot enough to soften and stick/fuse together. You can get up to about 95% density this way. With SLM it is possible to truly melt the powder and get to 99.95% density.
I can’t wait when Walmart sells that printer for 99$
Russian Bot why would you want a piece of shit printer when there would be better high end 4D printers available by that time?
Shity tool = shity job!
I find this utterly fascinating from a technical perspective.
The ability to produce parts in this way will only be improved and refined as time goes by.
Likewise, I expect new processes will come into being as new machines are developed.
Thank you for this highly interesting and informative insight into printing components. Subscribed.
Not only is it weaker it also cost 10x more. what an innovatoin.
What is your evidence that it's weaker? SLS metal parts are similar in strength to billet. They're weaker than forged, but the process is much cheaper than forging and allows for significantly higher design complexity without an increase in cost. Sounds like you're pulling things out your ass to me.
@@Tristor86 first off cast parts are way cheaper then 3d printed. like WAY cheaper. and billet is way strong then cast or 3d printed. do you get all of your knoledge from rediulous youtube videos like this one?
michael provost: I’m an engineer and I fabricate parts for race cars. I know a thing or two, as does Papadakis Racing. Where are you getting your information about the strength of SLS? It’s not as strong as billet, but very close, and allows significantly more complex designs to be produced which is an acceptable trade off to improve packaging and efficiency.
@@Tristor86 if i hit a piece of billet aluminum with a hammer its going to dent a little, if i hit a piece of that with a hammer it breaks. yea you can make complex designs with it. that is the only advantage. maybe another 10 or 20 years the technology will catch up to the hype.
michael provost: You’re making claims not in evidence. What you said is not an accurate statement. I don’t have anymore time to waste replying to you. You don’t know what you’re talking about.
This is one of those times when technology is absolutely amazing! Great stuff. Cheers fellas.
Pap the Aliens called, said they want their technology back.
I am amazed at the level of high tech engineering needed for this project.
This is literally design rocket science and I know what I'm talking about : I am an aerospace engineer
$10K later and we have a converted direct injection to port injection setup.
Hopefully they run both like newer Coyote engines
@@dhodg777 Looking at the dyno vid the direct injection didn't work out so well.
@@mrred1012 they did not use direct injection so injectors had no fuel flow = no cooling so they just melt and burn out, thats why its hard to install a LPG to direct injected engines
@Clifton Green that's really besides the point. I merely meant that it could be spent on upgraded direct injection technology. Which is going to be the future anyways. The only current obstacle is cleaning of the valves that port injection offers.
@Clifton Green he already dyno the engine with only port injection and direct injectors literally get burnt out, check he's other videos
Wow, I have huge respect for your knowledge and capabilities. You are right up my alley as far as the quest for engine building and design knowledge through all types of racing and all types of engines. 1000bhp is a very impressive number for a production based motor. The only itch I have is with the amount of money that is invested to obtain these results. I am sure that with the considerable resources put at your disposal, similar results could be had with a lot of other production based engines from different manufacturers which sort of takes away some of the glory that Toyota or BMW would like to earn as a result of this build. With that being said, I will continue watching your videos with great admiration. Thank you.
Technology is getting close to science fiction.
SiFy Up your GAME LOOL
The amount of technology used in this project is overwhelming.
I'm scratching my head on why supports were needed at all? SLS is inherently self-supporting.
SLS is not self-supporting for metal. Just another reason this should have been done with RapidNylon.com
It's not really, the wiper pushes the powder down as it travels and may dislodge bits of the build
Awesome.... Unlimited application... So we can literally make everything bespoke - if we have the money - now...
Advance Aliens: Hold my beer. Well mold material out of atoms and energy into the 5D
I feel so lucky to have insight into engine building this advanced.
I am missing the point as you could have made a STRONGER carbon fiber manifold for less money as saved a lot of weight. Who decided to do this?
Susan.
This is a very well-edited video. I really appreciate that you keep everything short, to the point, but still take the time to explain everything.
$8k for ten pounds! I wanna know how much it cost to build this 1000hp engine, amazing!
The manifold is a prototype, so it'll always be really expensive.
good of you to make this vid. it lets us keep up with this new technology
In the future, when something breaks, people will go to the printing Shop next to them and not the parts store.
Everyone will have one, just like a flat screen tv, or microwave.
It's way cheaper to just produce a few 1000 extra parts, and sell them, rather than printing every replacement part. Plus, as you saw in this video, they aren't ready to go out of the printer, they still need some machining.
Actually this will just decrease the cost of production. You will still be buying parts, they will just be cheaper.
Surely you're not suggesting that someone could blow the welds on an intake manifold?
Layer by layer. Very interesting. I was picturing liquified aluminum being squirted from a single tip. Now I see how it can work.
Yeah, there's no way having that printed in wax then doing a basic cast would be cheaper or quicker.
3d printing is the way of the future. Enging pats, body panels, interior bits. possibilities are endless.
Very true but the sad part is its going to put a lot of humans out of a job.
It's a great manufacturing technology, but it isn't going to replace all others. Yes, you can make some incredible shapes and parts that would otherwise not be possible to build with 3D printing, but if you design for "standard" methods, they are often just faster and cheaper. Yes, 3d printing will get better, but so will every other manufacturing method.
Welcome to the Future 😳
I see where this has already made parts for old radios and things that you cannot get anymore that's a plus
We live in a world where we can 3D print things out of metal, yet the jury is still out on what a woman is. Mind boggling.

We live in a world where we can 3D print things out of metal, yet some people still feel the need to police what other people do with their own bodies. Mind boggling.
Algunas personas quieren libertad absoluta para el uso de los cuerpos, hasta que alguien usa esa libertad absoluta para hacerles algo que no quieren
This channel is PHENOMENAL!!! So concise, easy to understand, and interesting content!
Careful you don't blow the welds on that intake manifold or you will owe me a 10second car.
God I love these videos! No waffling, no bullshit, just knowledge bombs.
Did anyone else at first glance think why would they 3D printed the welds? Haha
That was my question... since it was CAD designed, and printed in .002" layers, why are there obvious tig welded seams around it?
It was printed in separate pieces then welded together. Probably limited to size of printer or to guarantee perfect fitment.
This is just too cool, oldschool and state of the art tech working together to create something that did not exist before :)
"Typically they wear respirators because the aluminum is so small and dangerous"
JustWasted3HoursHere lmao I was seriously thinking the same thing aha.
Its amazing all the time and effort you guys are putting into this Bseries engine. In such a short period of time you have proven to some of the keyboard warriors that as time goes on products improve and you cant get stuck in the past. 2J/RB time is over like the push rod V8
those engines will always be legendary in their own right. gotta appreciate all technology for what it was at the time, not what it competes with today
Custom tools, drill guide! Awesome. I couldn't imagine having the capability to create my own tools
that's really UNIQUE content about autosport, please bring more of this!
Thanks PR for sharing your awesome video.
Your quality of work is superior, you guys have set the bar on 2020 GR supra to another level.
Looking forward to your next video
Any advantages over a lost wax casting? There are a few variations where a part master can be directly 3D printed (rapid wax) or a mold for wax parts can be 3D printed.
In this application maybe not a significant gain.
The fundamental benefits of 3D printing is the ability to print parts that are physically impossible to machine otherwise (think of a complex lattice internal structure). Another benefit is the weight savings without a loss in structural integrity (maybe even an increase in structural integrity) that can be made from using clever designs such as the lattice structure.
Awesomeness at its finest, keep up the wonderful work that you do extracting horsepower where there was limited or restricted. Have a great day.
That like to dislike ratio is insane! Keep up the good work Steph.
"a cast piece" not "a casted piece" it's called sintering not "welding the powder together" this technique is referred to as "SLS" Selective Laser Sintering. You forgot to mention that the sintered piece is "baked" to strenghten the bonds of the sintered material. very enjoyable to see this content. Thank you for bringing it to us.
This is not Selective Laser Sintering. SLS was something of about a decade ago. Laser power has increased over the years, and so has the quality of the optics. The result is machines that really do Selective Laser Melting (SLM) to 99.95% volume density.
Modern machines can still do SLS, if the specific goal is to make porous parts (say, filters) but all modern machines do SLM now. And that's really melting the powder at microscopic level, no need to sinter afterwards.
(As an aside, there are also modern 3D printing techniques that do need de-binding and sintering, but those are called binder jetting, where powder is mixed with a plastic/wax/binder and then printed with an extrusion nozzle. The resulting part does need de-binding and sintering. But that's not SLS.)
For this part I understand it if you leave it as be, but for more structural or high load parts you would ideally want to 'cure' the part by subjecting it to isostatic high pressure and heat to consolidate the metal grain and force out any cavities between the metal welding patterns, right?
For heat subjected objects these cavities could provide more insulation?
I would think the high temp plastic the oem intake manifolds use would suffice. That stuff can now be printed as well.
thanks for the no-nonsense approach to the video.
If you are not already the premier engineer pushing the limits of the BMW B58 then you are definitely on the way. 👍🏁❤️
They have one of these at my uni, but they have titanium powder instead of aluminium. They make custom parts for commercial aircraft and 3d modelled titanium bone prostheses.
I’m currently learning autodesk inventor in high school right now. Hope to get really good at it one day, I’d love to cad model and CNC a functioning engine.
For drill guides I usually design them with press in bearings, for harder metals sometimes the drill will eat into the steel sleeves making them less accurate, but awesome video! what do you guys use to design the manifolds? Is there any sort of CFD calculations that dictate how they should be designed?
I don't think there's a word in English to describe the awesomeness of this.
@notperfect give me one word.
The shape of this manifold is interesting. Looks like a really sharp angle for the air to get to cylinder 1?
I LOVE your videos - best technical car content on the Internet! 👍
Impressive. I was watching with great interest as you tightened the fuel rail to the manifold. I wanted to see just how tight you were willing to go on this experimental part! I see that you didn't push it too far.
I totally want like a dozen Parts made in this machine for my L28et but I'm sure they would want some ridiculous amount of money. Super exciting to see technology come along maybe someday normal people can afford them.
Great process for a one off part. But traditional casting seems much more cost/time effective than a 52hour print time. Expecially if you ever need replacement in the future. And at a cost of 8,000? I wish the video compared the cost and time frame of other processes, either cast or hand bent tube and welded. If you can drill a fuel injector mount, can it be welded on like an exhaust o2 bung?
Edit: I know someone will say about flow, better flow always results in more power but the gains are much less on the boost side.
Daaaamn! That 4 minutes went by like 40 seconds! I NEED MOOOOAAAR PLEASE!
hmmm you didn't talk about how the sintering process leaves the metal more brittle, and how you're overcoming it.
