Working 3D-Printed Car Engine Models!

We meet Eric Harrell, who brought his collection of functional 3d-printed car engines and transmissions to this year's Maker Faire! Eric shows us his 1/3rd scale engines, which he designs from reference schematics and measurements to highlight how real engines work. Eric has also made his files available online for anyone to make their own replicas!

[@velocirock7421]

This guy is really impressive. You could tell how interested they were about how he did all of this.

[@devilsoffspring5519]

With a different camshaft design, you could probably run these on compressed air (for a little while.)

[@swankscabinet1625]

Now I think if you took each piece and cast it from aluminum or something, you could run it off of some low heat fuels

[@Ry_TSG]

You should look at Tom Scanton on yt, he did something similar

[@amshermansen]

This is seriously cool. Just imagine how much you could learn as an engineer or mechanic by taking a course where your ultimate goal would be to literally build an engine. You'd understand the entire process and know what all of the parts do.

[@crispybacon4240]

*"YOU WOULDN'T DOWNLOAD A CAR"* Wait... Hang on...

[@crispybacon4240]

+Puddin Tater What's Ancientreality?

[@crispybacon4240]

+Puddin Tater The "you wouldn't download a car" meme comes from the anti piracy clip that used to play before movies, this Ancientreality guy didn't come up with it.

[@crispybacon4240]

+Puddin Tater That'd mean they're violating the terms of service, being well under 13 years old.

[@AKindChap]

Aren't old enough? What are you talking about? DVD is still prevalent.

[@Boomken76]

Now if he said beta-max or laser disk that would be diff. XD

[@StevenMartinGuitar]

Talented dudes like this need more time/money/resources. He's obviously very clued up, some company needs to get behind him, the results (and furthering the limits of 3D printing) would be incredible!

[@TheSweeny99]

he seems pretty real, my guy

[@miyawkat8018]

yeah the look on his face that he wants to do more and try other stuff but he cant because of the resources he needs. i hope Tested (or frank) can collaborate with him.

[@d4rkhound388]

TJ-N do you know how hard it is to find certain engines, he could make a business based on designing engines, 3d printing them and then making a mold of said engines.

[@huggysocks]

Couldn't agree more, how is this not funded in some way this is incredibly complex and this guy has an icredible understanding of complex machinery

[@mau3304]

StevenMartinGuitar why should they people working on engines are all like him he‘s nothing special

[@k.k.hickey4624]

Frank seemed super into this, I'd love to see what he could do with one of these with his skill and enthusiasm.

[@Gerald5000]

Yeah Frank is a Motocross guy, so he knows engines, and you can tell he wants to recast some of the 3D printed stuff in clear resin.

[@ruprechtmudorc2115]

I never cease to be amazed at how many extraordinarily skilled people there are in this world and just what they could achieve together if their efforts were recognised and given free rein. There is very little they could not do.

[@batatinha408]

This is really revolutionary, engines that are rare or extinct can me more accessible to have or recreate in the future, that's just incredible.

[@shannonsisk]

I thought the engines were pretty neat. Then I saw the manual transmissions. That is amazing to see at that scale. Even the synchronizers appeared to be there. That's amazing. Very very very impressive

[@nwbackcountry5327]

AvE T-shirt! AvE needs a 3D printed clapped out Bridgeport.

[@oscarzt1652]

NWBackcountry keep yer slick some place nice

[@Praesesza]

AvE is slowly taking over the T-Shirt industry... :D

[@Schpoople]

This was really cool but it seems like they used a lot of the time to bust this guy's balls when he's got such a cool product to present. Lol

[@lanceduckworth4927]

Ya, he probably had little time to prepare to be interviewed and knows what he wants to do. They're being encouraging but I'm sure he's doing the best he can do with time and experience he has.

[@EddyKorgo]

I think they were just excited and they fled him with ideas and tips

[@lanceduckworth4927]

Eduard Šajgalik yeah, he was just a bit overwhelmed by it I guess. :)

[@vejymonsta3006]

lol they're not busting his balls. He just did a really good job and they want to see more stuff from him.

[@BGraves]

This guy has all the experience required to do anything they encouraged him to do.

[@carolinabeacher1558]

the transparent engines they were talking about from the 70s/80s were called the visible v8, i had one as a kid

[@markg7030]

I had the same one in the 60's, It looks like its from the 50's.

[@RinksRides]

still available online.

[@boonehouston]

It's funny how the new generations are bringing back so much from the first technological boom and calling it an invention.

[@briangibson325]

Building a high rpm engine now except i painted my block still have alot of work to do its a 1960s that i bought off an old man for 30 bucks he was 10 when he built it and the block wasnt straight an parallel like it should so i had to disassemble and rebuild block is done but still need to fill block and heads with epoxy and tap for screws and bolts

[@djshotokan]

Thank you! Been looking for the name, I want to get a 351 windsor model!

[@lastcaress509]

Nice AvE shirt!

[@spoonnz]

FUCK YEAH!

[@thomasgreen2170]

clapped out bridgeport milling machine

[@Andrewlang90]

lastcaress509 Lovin the shirt, gonna get my own dirty dick beaters on one soon!!

[@thomasgreen2170]

everyone enjoys uncle bumble f*cks videos

[@edrees3874]

Good catch, son. I call you son on account of me knowin' your mother so well.

[@andrewnprice]

Love Frank's AVE shirt. Good to see them supporting other KZbin channels.

[@DoctorZisIN]

Frank to the person who finds a cure for cancer: "Oh great! You cured cancer, but did you think of curing ebola, coronary disease and alzheimer's as well?"

[@janrodel3511]

Grafight23 thats another project. I'll get to that when i have the time

[@MEGASTRIX]

Grafight23 The cure has been found plenty of times. But theres no money in cure.

[@DoctorZisIN]

There's plenty of money in cure, the problem is that Cancer is a feature, not a bug. Your body can't tell the difference between normal cells and cancer cells. It's evolution's way of keeping human population in check. Looking for a cure for cancer is like looking for a cure for death.

[@Phoenixflame87]

People like to use the term "cure for cancer," but cancer is hundreds of diseases. Some forms are curable, others are treatable, but it's extremely difficult to find a catch-all cure because for how many different forms the diseases take.

[@DoctorZisIN]

Exactly, plus cancer also has many causes and many symptoms, which often mimic those of other illnesses so it's easily misdiagnosed, and not treated in time.

[@mckbalisong]

I love that someone took the time and effort to do this, I grew up rebuilding chevy 454 and 502 engines for boats, the only thing that I can criticize if the last engine in the video, he has the exhaust coming out of the block, not the heads where it's supposed to be, and the engine is a v8 and there's only 3 exhaust outlets , not 4... don't get me wrong, I have to give this guy credit for doing all of this, it takes a lot of time.

[@MrProzak06]

Sitting around on holiday, decided to start looking at new projects for when I get home. This is perfect! What a total legend!

[@bagassaputra8716]

7 years later and I definitely will do the lost pla casting. 😊 Thank you guys

[@jondoe141]

Theres something about an engine that has captivated me since i was a kid. Maybe its just the beauty in the engineering of all the parts noving. Just a true thing of beauty

[@mr.headcrab31]

You see? THIS is what we want. Neat stuff that's not just corporate brown nosing. The peeks into the behind the scenes of films is cool, don't get me wrong, but some of the other segments have felt a little too sponsored for our tastes. Please keep with this style of video, it feels much more genuine. Thanks,

[@UnderdogSMO]

but it doesn't pay the bills

[@pingushit]

& if they don't get their bills paid, how are they able to afford to bring these sort of awesome genuine content to us?

[@mr.headcrab31]

It's not that sponsored videos aren't important, especially with how the whole advertiser thing is going as of late, but a whole lot of vids as of late have felt really, REALLY fake. Transparency is the key, Fox letting Adam have access to the hero spacesuit from The Martian to promote the home release was cool, the last two mailbags, on the other hand, felt like ads for the prop auction house and the foam sword manufacturer disguised badly. Adam's PSAs from the NHTSA were fine, the last few Maker spotlights have been pushing it. Maker was always "The Amateur doing cool things (IN A CAVE) with a box of scraps." I'm sorry, but once you have an "Industrial Division" for your products, you've graduated from an Amateur "Maker", to a full blown Manufacturer. Don't get me wrong, as long as the content is fresh and interesting, we'll love it, but some aspects are getting stale. Also, sorry, that turned into a bit of a rant.

[@Antenox]

Turn off your adblocks and/or subscribe to KZbin Red

[@stevanz1]

Those projects pay for these videos.

[@DigiFrogMage]

I think i finally found a really good reason to visit the maker spaces with 3D printers near me. I want these!

[@spybot5000]

This makes me really happy because the 22RE was my very first engine that I took apart and put back together (which I did 3 times because I'm dumb)

[@bryanc1975]

I am currently working on building his Toyota engine. I gotta say, it's coming out pretty cool so far. Our printer is not an expensive, fancy one but the parts are fitting together perfectly. These designs are freaking awesome.

[@dpreetam]

I did a 427 engine block in AutoCAD my senior year in highschool, back in 2006. My 18 year old self really appreciates this.

[@rustythrottle5713]

Very cool!!!! The possibilities of these little engines are almost limitless. They are a fantastic way of showing a person with no automotive knowledge how something works. Great job, and please keep up the hard work!

[@DeliciousDeBlair]

I really appreciate his flat out honesty about what he will and will not do.

[@ookland81]

I love the honest views expressed. He is not claiming to be anything special and was smart enough to work with in his realistic ability. Nice guy. Nice work.

[@teredude]

Brilliant!!!!! These should be in Schools!!!! This is what I grew up on were the Monogram Visible V8/ everything else. Thank you. Do the Automatic Transmission and the magic goes away maybe not.

[@jaratt85]

Frank cracks me up, his mind works a lot like mine when it comes to mechanical stuff. You can definitely see he's the gearhead of the outfit. I hope he ends up making his own engine on here and getting it running, running a methanol flathead recreation would be really cool... you could even put a blower and mechanical fuel injection on it and... lol

[@pingushit]

But gotta remind him though, not to make it too efficient or too great of a viable alternative to currently used fuel, if not he might get shot in the head. Lmao

[@jaratt85]

it's a flathead, it will never be efficient, just cool. Their design isn't used for anything other than lawnmower engines anymore for a reason, they don't make much power and the don't get good economy.. They are just simple and cool to look at. A fully race built Flathead Ford V8 running a big supercharger, fuel injection and methanol typically makes maybe 400hp... you can easily do that with a low compression naturally aspirated 302 these days.

[@internettoughguy]

J.A.Ratt85 We're talking about a plastic model buddy. Calm down with the hp and efficiency stuff.

[@FrankIppolito]

dont worry! i'm on it!

[@d4rkhound388]

Internet tough guy, he is giving free info, hush and take the info in.

[@akshaypherwani7084]

The best thing I've seen so far

[@browndog9402]

That was so cool, he could print a body that would fit on the chassis and make it remote control, that would be so sick.

[@dunnyboy4]

I saw the flathead v8 and was very happy

[@geojake]

"What's your design process?" "I'm basically a mechanical engineering savant." OK

[@Xxxxxxxsx]

😂😂😂😂😂😂😂😂😂😂

[@kevinchamberlain7928]

Excellent educational model for budding mechanics and printers!

[@drad1537]

This guy is building all this with a cheap printer that everyone can afford or use...not the industrial printer for the big companies. Excellent work sir!! Hat is off too you!!

[@radwizard]

Always the ego trick pops out when jealous...... Thank You for taking the time to share your motor parts online. Really amazing work!

[@robkennedy3000]

i found these a couple months back and now im determined to get a printer to try these.. :D

[@longjohn526]

I actually made the Toyota motor with some user designed additions and it is simply brilliant. I also have all the hardware to make the transmission and the transfer box and I hope to get around to starting that in a couple of months ..... It still blows me away how well all the parts, especially the block, is modeled to be detailed but still easy to print. Highly recommended for a complex project that is just going to work.

[@FrankIppolito]

I cant wait to print one of these and build it!

[@hazysativa3045]

Interviewer excitement level = 100. Builders excitement level = 1

[@spagehttiboy990]

I'm so glad he mentioned rotaries! I was waiting for him to say that through the whole video

[@mraaaaaaa]

"Transmission.." *shows a differential...

[@thestonedraider8684]

First I thought what's the problem that's part of the transition(its transmitting power from the engine), then I remembered Americans call the gearbox the Transmission.

[@simplelifediy1772]

thank you for saying, "the engine is powered by the motor" lol

[@F22PilotArcile]

Hey hey, Frank is an AvE fan!

[@ah-ray]

F22_Pilot who isn't :)

[@F22PilotArcile]

One of the best KZbin channels ever.

[@Tasman_Ninja]

Frank is an asshole. (At least in this video to the guy)

[@groundmasterc]

I think he was just excited to get his hands on it and assumed the creator would be equally excited about the project.

[@qroconnor8812]

Good ol' uncle bumblefuck

[@freddybee4029]

You forgot the most important cool part. The distributor and spark plug lights. That is what set the original V8 plastic engines apart from the cheap competition.

[@danh5150]

I regret that I can only give this gentleman one thumbs up. Well done, sir!! * polite clap *

[@dwaynem8015]

They were fixing. Trying to figure out how they could do it. This is great. Very nice.

[@impulse_media]

This is amazing, in past years I had searched for scale models to visually look over to stir creative ideas. Watching this segment opened a can of worms thank you for sharing!

[@algostine]

The lowest temperature fuel is compressed air. It would be ideal as it cools as it expands. It would require no modification to your prints and help prevent the plastic pieces from melting at higher RPMs

[@algostine]

kzbin.info/www/bejne/n3XUnoOqgpynq6s

[@egoode3852]

Bravo on the Manual transmission

[@randycoolbaugh1408]

holly crap! that complete chassis is awesome! I would totally buy one in kit form!

[@BisdremisKostas]

wow... this dude after all this must ROCK @ solidworks

[@a7dad822]

To run them on their own power, you could go pneumatic, using a small air-compressor to provide some pressure. It would mean altering valve timing though (would basically mean becoming a two-stroke). Dig the subie motor.

[@charlietate3271]

Franks shirt is skookum as frig!

[@elvisjonesus]

That guy has some serious talent .

[@keithlucas6260]

I built two Prusa original Clones and bought the FlashForge Dreamer. So far since I'm a RC pilot and fly a 1938 Super Stearman with a Radial Engine, I have 3d printed a working five cylinder radial engine. They actually print stainless steel and other materials, even biometric strands. Amazing what they are doing. I have to admit that watching it reminds me of several scriptures where God created from the dust into a form, whereas up until now mankind has only been able to whittle material into a form. As a master machinist, this is awesome, and as a model builder just incredible.

[@keithlucas6260]

Ace Buck .....far from being a rich kid, I work for a living. I don't buy fashion designer clothes or Apple "i" products, nor do I spend money on cigarettes, weed, or gamer's software and pay to play websites. The money I do have went to pay off the mortgage and buy another house to rent out. I also am a machinist not a dishwasher.

[@jnuxca]

dude the gearbox is beautiful

[@91rickstar]

+Tested you should of asked for him to make a air powered motor or at least a single cylinder engine that works off compressed air

[@idkzero]

this guy did an amazing job -- I understand what he meant by the "lack of time".

[@MaxMakerChannel]

I can tell that this guy is totally exhausted. I bet he worked until the last minute to get ready for maker faire.

[@brandonbocklund]

Eric also has a KZbin channel if you want to see more footage!

[@jakebrang]

"can't explain how a transmission works, its impossible" I literally had to take a class that had me memorize every part in a transmission, then power flow between each gear and how the different mesh outputs power. its very possible, you just don't know how.

[@kencohagen4967]

They are already going 4 rotor style engines based on Mazdas 2 and Three rotor engines. There's another market to be had. I would consider that instead of the Poppet valve head for an overlooked engines that rocked when it go some attention, but could loose a little more refinement. Against, let me know! I've got three designes already in use and ideas for many more!

[@Yathuprem]

That's awesome. Especially transmissions

[@c.j.tonnes7648]

he is the most capable and pessimistic person I've ever seen on the internet

[@JDevine687]

I remember seeing that very first 22R, and then came the transmission and transfer case. It was super cool to see! Props of the AvE shirt! 8)

[@dougsmith8838]

Did anyone else notice both the intake and exhaust valves on at least one cylinder of his "Boxer" engine open and close at the same time? Very cool models though. I have never dealt with a 3d printer.

[@ThZuao]

The title makes it seem that they are actually burning fuel.

[@josewarren1441]

Thauã Aguirre how?

[@gasser5001]

working engine model...not running mini motor.

[@phatvortex]

So you're telling me when an internal combustion engine is "working" it isn't running on fuel? Interesting logic there..........

[@KrustyKlown]

Let's see someone make a plastic 3D printed gasoline engine that actually runs! ... it's possible .. with the right design and at a VERY low power output (i.e. runs very slow)... keeping part temps really low. Such an engine would have no practical use, but would be a fun project. Something like an occasionally firing "hit miss" type motor. The parts could be made hollow with water cooling channels, imagine a water cooled piston, with water hoses .. feasible at very low rpm.

[@laser69beam]

Nooooo....! Tested NEVER clickbaits..! Pfffft

[@nfssable]

I love these engines & the drivetrain model is pure AMAZING!!

[@ahmaddarwish1486]

working is running on its own power

[@TheRedSlead]

Not even a single word about that lovely LS right there 😓💔

[@rangedayvlogs814]

Wow good work on using files off of thingiverse

[@dawheele1]

I have a new design for an engine head that will work with a normal piston bottom end if your interested. Its not patented and can be crowd sourced by you if you want. Maybe we could make some money selling the models. Its a spring less valve head with removes most resistance from the engine and allows for extremely high ROMs and lots of power while being above 80% efficient. It won't be able to be patented once its shown to the public so the big companies won't have any control over it.

[@davebrittain9216]

These weird guys that take the time to do this kind of stuff are really the coolest guys ever!

[@FraktalPriest]

Right on!

[@gtb81.]

you guys should do an episode about making a fully functional one

[@romulas-cushmanproject3273]

1:19 that turbo flutter tho!!

[@MyBrothersMario]

casting a full functional small scale engine and transmission that runs on gas could be epic for a go kart if you could get the tolerances tight enough.

[@MrMartinSchou]

Since a combustion engine is really "just" an air engine working on the principle of phase change, you wouldn't necessarily need to run it with a combustible fuel. If the materials could handle it, you could use things like dry ice or liquid nitrogen and use their phase change into gas to power it. It's be trickier to get the fuel for it, but it's not going to end up melting the parts or burning things down if people get careless.

[@kurstinday]

Been inside a few transmissions, this is awesome!

[@jannowakowski2914]

Yay, Frank is wearing AvE shirt of awesomeness

[@billysgeo]

Cockford Ollie

[@thecentralscrutinizer5105]

I had the see-thru Wankel engine kit in 6th grade, very kewl to think ya can now make it at home 40 years later...

[@MaxPower_Designs]

Nice Flathead with a Edmunds intake!

[@JoelTGM]

that was done with a cheap 3d printer? it looks so sharp and smooth. that's really impressive.

[@bryanc1975]

It is. I'm making these parts on a printer that cost 400 bucks, and so far the fit has been almost perfect.

[@mohammadshahidkhan3048]

Very nice for new engineers

[@sinebar]

An 18 cylinder double row radial engine would be a nice challenge.

[@djmips]

This guy refuses to get sidetracked. That's how you get stuff done.

[@panamericaco]

Aweeeesome! Never cared for 3d Printers but as a car guy I think I have to buy one now!

[@Skyliner_369]

First thing I notice: A picture of the old clapped out Bridgeport milling machine with the text, "ENGAGE SAFETY SQUINTS!" Somebody is a fan of AvE lol

[@Nellosphere]

I would love to see magnetic pistons and magnetic headers to see if they can improve efficiency. I wonder if you could make a turbo fan that produces thrust due to vacuum instead of heat.

[@videoaccount5676]

Those are not working engines, those are moving models.

[@sinnison23]

Agreed, I had envisioned them actually producing work through combustion of some fashion, not mechanically operated by a separate source.

[@christianled5972]

ya but its a step in the right direction. more durable filament and some more robust designs can create something fully functional.

[@Daunlouded]

Actually, they are working engines. Instead of gas they use electricity to work.

[@abaelkassim8229]

the manufacture of a thermal engine requires more than an engineer is a story that lasted a hundred years, mastering the development of a single part would be an extraordinary success

[@SonofSethoitae]

Yeah, but in theory you could use these models, print full sized parts, cast them in metal via Lost PLA, and build and actual engine. It would take forever, and quality control would be a crapshoot though.

[@Chukijay]

I'm so glad Frank was there to chime in. I love Norm but auto stuff is too far out of his wheelhouse. I was waiting for rotaries to be mentioned THE WHOLE VIDEO and thought I was going to be let down, then BOOM Frank threw it out there.

[@joshsoorlin579]

J W whos the guy that theyre interviewing - does he have ig?

[@kimsylvester964]

Very cool, can't wait to see the rotary (13b with twin turbos) I hope. Good luck to you.

[@M3rVsT4H]

This is awesome, went and downloaded immediately.

[@KevinACarter]

Cool video. He's put a lot of work into these. I also dig the BP shirt.

[@fdr100100]

This I'd dope you could actually make a fully working car model with a working engine

[@MrNisaacs]

Props on the AvE shirt man!

[@mexicansuperman123]

That is cool as hell.

[@legostar55]

I think that guy should make an automatic transmission because that would be so cool.
