@Nat Filer noo way man, I literally said to myself after he said “Beautiful! Look at this cylinder head” I said bro that looks like a ball sack... no way someone didn’t point this out in the comments and he first comment I see is yours. That made my day lmaoo
yes that stuff may last and its easy to mould, ive had an idea for a while for PF about a desert island special, thing you could make from it to get your escape engine running! his bottle carburettor gave me the idea, thus a carb made from bamboo and pipes made from natural rubber tree, clay head, maybe ferment alcohol from coconut milk for fuel! lol, make some kind of oil for the engine from (something!, fish or veggie oil ?)
Not all plastic. There are “thermoplastics” which are designed to withstand very high temperatures. Those don’t melt. They are used in products such as fireplace doors, intake manifolds, and BBQ grill parts. However, when they sustain higher temperatures than they are rated to handle, they become brittle and burn.
I love that your videos almost always feel like they are your first few videos. I have been following since the beginning, so it is really nice seeing you stay true to quality and seeking new ways to make interesting and relevant content. All the best!
Your vids are fun and educational. Injection molded ABS parts soften between 90 and 100 deg. C so I expected these results, but they were still fun. ABS is the most commonly plated plastic for exterior automotive applications. Presently, after several steps, the first metal layer is electroless copper, but before stable electroless copper baths were developed, low temperature (alkaline) electroless nickel-phosphorous baths were used. The acidic Ni-P baths have numerous advantages over the low temp ones, but they operate around 95 deg. C and distort the parts, so the alkaline baths were used (25-40 deg. C). I'm going to add one more thing. At one time one of the automotive manufactures looked into using thermoset polymeric composites (not ABS) as a replacement for rotating and reciprocating (but not exposed to flame) engine components. However, the team was small and when the leader left the company, the project died. That was over 30 years ago.
I wish I could say more, but the information is proprietary (and probably forgotten entirely by the corporation) so I can't give the details on the engine parts. But I'll say that the project was discontinued because the key person left, not because it ran into technical road blocks.
Lassi Kinnunen Yes, there are. But the parts that they were examining were a lot more difficult to replace than what you listed and I don't want to say what they were. They're the kind of things that you'd say "I never thought that they could use plastics there."
I found your channel about a year ago when I was stuck in bed for months because of my illness and ever since then I’ve been a religious subscriber to your channel. I just gotta say that I absolutely love your videos and I want to do videos like this so bad. But anyways thank you for all these entertaining experiments keep it up!🤘🏻
Your videos pull me in like the tractor beam on the Death Star. I was searching for something else on TH-cam, but when I saw you trying out a 3D printed cylinder head, I just couldn't resist..
If I could get my hands on that STL file or the part, I would be happy to send you that same part printed in a more temperature resistant material, such as carbon fiber nylon or polycarbonate.
The problem is that fused filament disposition relies on using materials that melt at low temperatures, a 3d printed plastic cylinder head would either need a temperature resistant coating or some better cooling system, maybe running oil through the head. Or an upgraded printer and some very high temperature plastic. Or maybe water injection into the cylinder during the exhaust cycle to take the heat out before it builds up.
Polycarbonate has a 66psi tensile strength at 260F ish after hardening. It will break under pressure. Nylon X will survive the pressure but temperature beyond 320F will melt it. Depends as pressure and temperature at the same time and increase stress in the material to crack and blow out if the material isn't able to cure or set properly during printing and curing stage.
Question: Carburetor before or after the turbo? Btw. I think it would be easier to test with a 3D-Printed adaptor for a 120mm PC-Fan to the intake before going all the way with a real turbo.
5:06 made me go back and watch for pink color by warm spots throughout the video. Like when he taps the spark plug threads in, or where he was holding it before. Cool!
This is a real issue. ABS vs. PLA - because ABS is a plastic derived from petroleum, so it can make toxic fumes. PLA is made from organic materials, so it is not toxic, but, as the video showed, not as strong and much more sensitive to heat.
I'd love to see a collab with you and CNC Kitchen, he has access to a lot of high tech filaments, and has even made some more high temp resistant stuff including annealed PLA!
@@ProjectFarm you can also try annealing pla, that can bump the heat resistance from 60°C to ~150°C However there is a problem with shrinking that needs to be accounted for, or look in to various high temp versions of printer plastics. CNC kitchen channel has a temperature test of common plastics for 3D printing.
Well, I'm now addicted to your videos!!! So applicable for my line of work. Have you ever run straight Sea Foam in a 2 stroke engine. I've heard that that's what it was used to be for marine applications. Would it run an Echo or Stihl?
DO NOT DO THAT. It is used to fog engines not be used as a fuel source! I'd be very concerned about your bearings and rings. Take my word for it or not but I'm ASE certified and also an Engineer. Bad idea.
I wonder if the green plastic head (forgot the material) would last longer if it had some sort of non-conductive seat for the spark plug. Like some sort of alloy that would dissipate heat enough for it to last longer. You could tap the plastic cylinder head and then add that alloy collar to it and the spark plug could screw into the collar. I'm having a hard time trying to convey what I mean and it might be outside of the scope of your experiment. Maybe bushing is a better word. 1911 pistols have this feature for the grips. It's a little grommet that screws into the frame so you can change screws without risking damage to the frame of the firearm.
Just an FYI for anyone that's interested. I just did a 5 page report on 3D printing/additive manufacturing last night for my engineering class, so I'm feeling especially knowledgeable for a few days until I forget it all... ABS vs PLA is a common decision to make when doing 'extruded material' 3D printing. ABS is a plastic made from petroleum, so it toxic (fumes). PLA is made from organic materials, so it is not toxic, but, as the video shows, it is not as strong and is more sensitive to heat.
WOW, I never would have guessed plastic fouling to be the reason it would have shut down. I would have guessed it would warp and blow out, great video!
Well, I assume everyone knew that the plastic would melt, no brainer. However, I wonder what would happen it you coated the plastic with heavy duty Epoxy first & then performed the test? Thanks again for a great video..........................
Ive been down this road with intake boots on a motorcycle engine. a thin layer is not enough to hold up to the heat and it ends up deforming anyways. Maybe a solid epoxy resin head would do ok? perhaps with some fiberglass mixed in
this has been done many times by the clueless in the world. The engine either wont start or if it does blows massive amounts of white smoke aka burnt oil out the muffler and spits oil out the carb and breather tube. u know for obvious reasons. until the oil is burned down to tolerable levels. or the exhaust valve carbons up and cant close causing it to stall and backfire out the carb.
My 200cc enduro did this when the carburetor float failed and filled the combustion chamber and crank case with gasoline. It was hydrolocked and would not turn over. I found this out when I opened the crank case and found a gallon of gas pouring out.
That is what my lawn mower started doing this year. the float was sticking I cleaned it but didn't work. kept filling the crank with gas causing hydro lock. I put a shut off valve on the gas line to fix it.
Aluminum heads survive even though the melting point for that metal is also much lower than the peak temperatures inside the cylinder. They last because they are actively cooled and have a high thermal conductivity (TC). So the internal surface never reaches its melting temperature. Plastic could probably hold up for much longer if you can find one with a much much higher TC and add active cooling. The problem is that (pure) aluminum's TC is 237 W/(mK) and that is more than 500 times higher than the TC of most plastics. Carbon fiber is supposedly 24 W/(mK), which is only off by a factor of 10, but that value may be for the fibers themselves and not for a bulk material which has them embedded. (Apologies if this point was made previously, currently 7636 comments, too many to read.)
"A light red"... I have to make this reference now... "Your armor is freaking pink." "It's not pink, it's a light red" "They already have a name for light red, know what it's called... PINK" One of my favorite lines from Red vs Blue...
Are used to work at a plastic injection molding facility for a good couple of years, and we would make these carbon fiber/polycarbonate gas pump regulators used in nearly all gas pumps produced in the midwest. They would be sent off to a cryogenic facility to remove excess flashing around the small openings in the center of the parts (one for intake of gasoline, another for distribution to the pump after being registered in the pumps). A box of 500 was $150,000!!! Insane! But, if there’d be any way to get a cylinder head made out of that material, that would be insane :D (which was primarily proprietary but I can say it was at least 70% carbon fiber, 25% polycarbonate, and 5% proprietary materials). The craziest part was, when they’d drop and hit a concrete floor, it would sound exactly like if you just took a handful of pocket change and dropped it on the concrete floor - no joke at all there! Thank you and the 3D printed part provider for making this video possible!
Being a 3D designer myself and working with these materials often, those are exactly the results I was expecting. PLA is usually printed at 210 Celcius, while ABS is typically printed at 250ish C. They do make HTPLA (high temp PLA) that might work a little better. What if you wrapped it in aluminum foil to keep it from melting.
Okay so I got it now! 3d printers are good for AR-15 lowers, soap dishes, little figures, and making parts for 3d printers. Not good at making cylinder heads. Got it. Thanks for laying this out for me!
Love your videos ...I now wait for them like I do my Farm Show magazine ! .....I offer this suggestion as a logical extension to your series of project videos ... A 3D Metal (many metals are available...from the super expensive to the common production engine manufacturing materials ) -Printed Cylinder head ....the capabilities of these additive emergent technologies is improving daily ...I can think of none better to test this challenge ...Thank you again for an engaging Channel !
You are correct, metal was used long before the industrial revolution but it was only possible to produce small quantities. The industrial revolution only happened after they discovered how to mass produce iron. That is the basis of what we now call the "Industrial Revolution."
I too would like to see the lubricity of fuels tested. I've heard it claimed that gasoline acts as a lubricant in the upper cylinder and that the addition of ethanol to gasoline robs it of its lubricity. Also some additives (ex. Lucas upper cylinder lubricant) claim to improve the lubricity of fuel to the end of improving gas mileage. I'd love to see those claims tested. But please don't set your workbench on fire in the process.
I personally have seen an increase of about 2 MPG in my 2004 Grand Caravan with the 3.3L in it using the Lucas. So its obviously doing something. It also increased the responsiveness of it as well. I run it every fill up.
5:51 "I'm going to start with a new sparkplug, and I'm going to go ahead and create a large gap just to avoid plastic causing it to fail on us." 6:21 The plastic melts, causing the sparkplug to blowout and fail on us. I just found it kind of funny that an extra step was taken to avoid the sparkplug getting plastic stuck on the electrode and causing it to not to function, but instead, it failed on us in a different way.
I do not think 3/4" thick Bakelite would be as brittle as you guys are thinking, I witnessed an old Bakelite phone handset which is far thinner, stand up to an amazing amount of impacts and blows without cracking or shattering. Also, I wonder if newly made Bakelite has different properties than aged as I would imagine it does.
Hi, I work on mopeds and two stroke scooters. One thing I heard is that you can take off the head gasket and run the engine with out it. I’ve never done this, but people say that this improves compression and bumps up performance. Would you be willing to debunk this?
Project Farm No problem. I’d recommend wet sanding the bottom of the cylinder head on a slab of granite so you can get a flat and even contact on the cylinder jug.
if the faces fit very well you can use a thin layer of gasket sealant (blue hylomar we used to use) some engines were indeed a precision fit with no gaskets
The performance increase is mainly due to having a tighter squish band, and not the modest bump in compression. A better way to achieve the same result is to have your head machined down, and still use the gasket. You have to measure your squish band and tell your machinist how much needs to be taken off the head.
You gotta try having another plastic cylinder head made and drill water jackets into it and cool the head and see how long it cant last then! That would be cool!
sounds like a good idea at first...but you'd probably have to make so many water channels that the structural integrity of the piece would be lost for a high-pressure application like this??
You could 3d print the water jacket. Base off of how much plastic is melted there the water jacket would have to be very close to the surface. Probably won't hold up to the combination then.
As far as I know, PLA fumes are not toxic (it's actually an organic compound if I'm not horribly mistaken), but ABS fumes definitely are. Tho, that is considering the pure plastic burning, not combined with fuel and/or oil.
Kalvinjj there's research suggesting some of the VOCs (volatile organic compounds) generated by heating PLA are toxic. There are countless organic compounds that are toxic, i.e. dioxin. Organic within chemistry is not the same as "organic" on a food label, it simply involves carbon atoms.
Nice insight John Ratko, not that I would be sniffing burnt PLA for fun but now I know it's a nice idea to ventilate enough the area around if I get to print with it. EDIT: yes I was familiar with the classification chemically about organic compounds, but funny enough, in this specific case, the compound itself may be organic even on the food sense, as it may be done from corn starch, sugar cane and other renewable sources
SRT8 MadMan when I was a kid we ran an old 2 horse tecumseh with peanut oil in it. Governor wide open & no load. It would sieze & free up as soon as she cooled down. Ran that way for maybe 3/4 tank of fuel until the rod let go & put a nice hole in the block.
You know, I wonder how one of these plastic cylinder heads would perform if the guy who sent them to you engineered them where the spark plug could still be screwed in with a recessed area while the cylinder head itself was much fatter and had cooling pipes running through it, connected to one of those PC water cooling systems or something that could cool down the plastic. Just makes you wonder. Seems the only reason the heads failed was due to heat.
TLDR - It would probably work if they made a high temperature plastic that could be printed, but that would probably be expensive! Love the train of thought on that, I'm a PC tech so I kinda wonder the same thing. Though I feel like a big issue would be if the car overheated and either boiled the liquid in those lines or melted them leaking it out. The design would probably either be expensive due to the amount of materials needed to be efficie t or really cheap due to failure rate becauseit how hot the normal operating temperature is and other systems could cause the engine to run hotter than normal too. So it would probably just require a better material.
I can’t see it working. Plastic doesn’t conduct heat very well, so the cooling system wouldn’t really cool the combustion chamber enough... which is where the failures are happening.
You could make it with some high temperature plastics. It'd be more expensive than just going and buying the best lawn mower money can buy. And retarded when I could make it out of aluminum for a hundred bucks.
TPU 95A makes really good gaskets and O-rings. Would like to see one of these heads made from CF nylon, I prefer SainSmart 25/75 black CF nylon. Polycarbonate would be cool too. Or maybe do a collab video with Vision Miner and have them print some heads out of PEEK and PEKK. My Ender 3 Pro is running Marlin 2.0 firmware on a 32 bit silent motherboard, Micro Swiss direct drive and all metal hot end kit, BLtouch auto bed leveling probe, textured glass bed that is hard mounted with solid bed mounts. It'll print anything from PLA, TPU, and all the way up to CF nylon and Polycarbonate. Also, ASA is easier and better than ABS. PCTG will be replacing PETG soon too.
do NOT lend a lawnmower to this man.
lol
I'd trust this man with any mechanical equipment as it is clear that he is very adept at fixing them.
Lmao
Ill give him a few just so he can keep doing these awsome videos
If you lend it, I assume he'll return it functioning.
Now, if you give him one, it's fair game.
How this guy gets his mower started with these heads is amazing, I can't get mine started with stock components, new spark plug and fresh gas.
Thank you for the feedback!
check the air filter
Your cylinder head might be made of a material too hard
My guess would be he starts it regularly and doesn't have it sitting for extended periods of time.

That's the recipe for refractory. Would definitely hold the heat but I think it might crack and start to flake out.

Interesting, so plastic melts when exposed to extreme temperatures.

Terry, Great job making those cylinder heads and thank you for making a video showing us how you made them!
PLA and ABS are 3d printed at less than 250*, 300+ from those small engines is just too much for those materials.
That kind of plastic intentionally melts at a low temperature so it can be printed. So it makes sense it would melt in the engine
you'd definitely need some extremely high temperature plastics. all though they're very hard to print

@@ProjectFarm you can also try annealing pla, that can bump the heat resistance from 60°C to ~150°C

The engine either wont start or if it does blows massive amounts of white smoke aka burnt oil out the muffler and spits oil out the carb and breather tube. u know for obvious reasons. until the oil is burned down to tolerable levels. or the exhaust valve carbons up and cant close causing it to stall and backfire out the carb.
My 200cc enduro did this when the carburetor float failed and filled the combustion chamber and crank case with gasoline. It was hydrolocked and would not turn over. I found this out when I opened the crank case and found a gallon of gas pouring out.
Yeah, generally the engine will just hydrolock, depending on how air-tight the crankcase is and how over full you fill it.
That is what my lawn mower started doing this year. the float was sticking I cleaned it but didn't work. kept filling the crank with gas causing hydro lock. I put a shut off valve on the gas line to fix it.
Does anybody else click "like" before one of his videos starts because you already know that you will ?? I do !
Thank you!!
Aluminum heads survive even though the melting point for that metal is also much lower than the peak temperatures inside the cylinder. They last because they are actively cooled and have a high thermal conductivity (TC). So the internal surface never reaches its melting temperature. Plastic could probably hold up for much longer if you can find one with a much much higher TC and add active cooling. The problem is that (pure) aluminum's TC is 237 W/(mK) and that is more than 500 times higher than the TC of most plastics. Carbon fiber is supposedly 24 W/(mK), which is only off by a factor of 10, but that value may be for the fibers themselves and not for a bulk material which has them embedded. (Apologies if this point was made previously, currently 7636 comments, too many to read.)
I could see that these cylinder heads would work on a compressor where they’re not exposed to the extremes of heat.

Are used to work at a plastic injection molding facility for a good couple of years, and we would make these carbon fiber/polycarbonate gas pump regulators used in nearly all gas pumps produced in the midwest. They would be sent off to a cryogenic facility to remove excess flashing around the small openings in the center of the parts (one for intake of gasoline, another for distribution to the pump after being registered in the pumps). A box of 500 was $150,000!!! Insane! But, if there’d be any way to get a cylinder head made out of that material, that would be insane :D (which was primarily proprietary but I can say it was at least 70% carbon fiber, 25% polycarbonate, and 5% proprietary materials). The craziest part was, when they’d drop and hit a concrete floor, it would sound exactly like if you just took a handful of pocket change and dropped it on the concrete floor - no joke at all there! Thank you and the 3D printed part provider for making this video possible!
You are welcome!
Being a 3D designer myself and working with these materials often, those are exactly the results I was expecting. PLA is usually printed at 210 Celcius, while ABS is typically printed at 250ish C. They do make HTPLA (high temp PLA) that might work a little better.
What if you wrapped it in aluminum foil to keep it from melting.
Great test idea! Thank you
Project Farm if you can provide me with the file or at least dimensions I'll print new parts for you
You know somethings not right when your cylinder head melts onto your spark plug.
lol!
bro when this guy holds back his smile at the start of every video I just cannot
Thank you! I'm having a lot of fun and it shows!
Okay so I got it now! 3d printers are good for AR-15 lowers, soap dishes, little figures, and making parts for 3d printers. Not good at making cylinder heads. Got it. Thanks for laying this out for me!
Fun video
Great video! Honestly exepcted better than I was thinking especially that ABS
Appreciate it!
a 3d printed piston would be interesting 🤔
Great recommendation!
I'm certain it would fail in seconds.
Ferrari is trying to do that with thier f1 engine!
Meh....2 second and it will blow up
piston would melt faster than the head, however a connecting rod would be cool to see.
wonder if glass could make a functional cylinder head!
Great recommendation.
zachary roach dew it
zachary roach probably not. I think it would shatter from thermal shock.
zachary roach but hey worth a try
borosilicate glass not affected by thermal shock
Love your videos ...I now wait for them like I do my Farm Show magazine ! .....I offer this suggestion as a logical extension to your series of project videos ... A 3D Metal (many metals are available...from the super expensive to the common production engine manufacturing materials ) -Printed Cylinder head ....the capabilities of these additive emergent technologies is improving daily ...I can think of none better to test this challenge ...Thank you again for an engaging Channel !
Thank you!
let's all acknowledge the fact the each 3d printed cylinder head probably took over 36 hours to print. lol. great video!
Thank you!
I think this shows how much we owe the industrial revolution. We take iron and steel for granted but they are truly wonder products.
Great point!
You are correct, metal was used long before the industrial revolution but it was only possible to produce small quantities.
The industrial revolution only happened after they discovered how to mass produce iron.
That is the basis of what we now call the "Industrial Revolution."
The plastic melted? Who woulda thought!?
lol. It was a fun experiment.
Project Farm is it possible to make a engine block out of carbon fiber
Lasted 17 seconds that's quite a bit longer then I last
Perhaps you need something 3D printed that will last a bit longer
TH-cam Admin that’s what she said.
NO bullshit. Straight to the point. Great presentation
Thank you very much!
*can you do the lubricity tester on fuels? Like petrol, 2stroke and most importantly JET1A fuel if possible?*
Thank you for the recommendation!
JET 1A is actually Diesel fuel, just as Kerosene is. JET is certified to be water and particulate free, but its just Diesel.
I too would like to see the lubricity of fuels tested. I've heard it claimed that gasoline acts as a lubricant in the upper cylinder and that the addition of ethanol to gasoline robs it of its lubricity. Also some additives (ex. Lucas upper cylinder lubricant) claim to improve the lubricity of fuel to the end of improving gas mileage. I'd love to see those claims tested. But please don't set your workbench on fire in the process.
I personally have seen an increase of about 2 MPG in my 2004 Grand Caravan with the 3.3L in it using the Lucas. So its obviously doing something. It also increased the responsiveness of it as well. I run it every fill up.
opossom1968
But does it have the same Lubricity? 🤔
4:47 that s a lot of damage!
lol. I agree!

Alec Marshall now that’s a lot of damage!
Terry needs to send you a 3D printed (metal) cylinder head.
Thank you for the video idea!
5:51 "I'm going to start with a new sparkplug, and I'm going to go ahead and create a large gap just to avoid plastic causing it to fail on us."
6:21 The plastic melts, causing the sparkplug to blowout and fail on us.
I just found it kind of funny that an extra step was taken to avoid the sparkplug getting plastic stuck on the electrode and causing it to not to function, but instead, it failed on us in a different way.
Thank you
*Project Farm* It's probably out of your viewers realm to manufacture, however I think a Bakelite cylinder head would be an interesting test.
Thanks for the video idea!
In my experience bakelite would just fracture. It's extremely hard and tough, but it doesn't stand up to sharp blows such as a combustion event.
Lefty eh ... Similar to what I was thinking. Figured its brittleness would cause it to crumble rather quickly.
I do not think 3/4" thick Bakelite would be as brittle as you guys are thinking, I witnessed an old Bakelite phone handset which is far thinner, stand up to an amazing amount of impacts and blows without cracking or shattering. Also, I wonder if newly made Bakelite has different properties than aged as I would imagine it does.
I love when people assume everyone else is either stupid or 17 years old. This isn't the Justin Beiber channel, Prolific...
Hi, I work on mopeds and two stroke scooters. One thing I heard is that you can take off the head gasket and run the engine with out it. I’ve never done this, but people say that this improves compression and bumps up performance. Would you be willing to debunk this?
Thanks for the video idea!
Project Farm No problem. I’d recommend wet sanding the bottom of the cylinder head on a slab of granite so you can get a flat and even contact on the cylinder jug.
if the faces fit very well you can use a thin layer of gasket sealant (blue hylomar we used to use) some engines were indeed a precision fit with no gaskets
You still need a gasket but get one with less thickness. You just don’t want anything to hit once you shorten the length.
The performance increase is mainly due to having a tighter squish band, and not the modest bump in compression. A better way to achieve the same result is to have your head machined down, and still use the gasket. You have to measure your squish band and tell your machinist how much needs to be taken off the head.
If you haven't already, you should do a revisit of this idea with higher end materials. I bet that glass filled nylon would last a lot longer.
So, the plastic used in hot-melt, additive layer 3D printing melts? Who knew?
You gotta try having another plastic cylinder head made and drill water jackets into it and cool the head and see how long it cant last then! That would be cool!
Great recommendation.
sounds like a good idea at first...but you'd probably have to make so many water channels that the structural integrity of the piece would be lost for a high-pressure application like this??
You could 3d print the water jacket. Base off of how much plastic is melted there the water jacket would have to be very close to the surface. Probably won't hold up to the combination then.
Very true from both of you. Good point
I don't know guys, would you need to sacrifice much strength?
th-cam.com/video/xV2gsWHhDhY/w-d-xo.html
Bet those special plastic exhaust fumes are a tad toxic.
I agree. I always wear a respirator during the videos involving smokey exhaust.
As far as I know, PLA fumes are not toxic (it's actually an organic compound if I'm not horribly mistaken), but ABS fumes definitely are.
Tho, that is considering the pure plastic burning, not combined with fuel and/or oil.
Kalvinjj there's research suggesting some of the VOCs (volatile organic compounds) generated by heating PLA are toxic. There are countless organic compounds that are toxic, i.e. dioxin. Organic within chemistry is not the same as "organic" on a food label, it simply involves carbon atoms.
All exhaust is a tad toxic, even natural gas.
Nice insight John Ratko, not that I would be sniffing burnt PLA for fun but now I know it's a nice idea to ventilate enough the area around if I get to print with it.
EDIT: yes I was familiar with the classification chemically about organic compounds, but funny enough, in this specific case, the compound itself may be organic even on the food sense, as it may be done from corn starch, sugar cane and other renewable sources
A guy that’s crafty enough to make those is probly from winkler, them boys are legit.
3d printing technology is still a work in progress. 40 seconds was actually beyond my expectations!
Great point! Thank you!
That was really interesting I never would have thought of that idea. I really want to see an engine with butter instead of oil.
Great video idea!
Ghee, I would too!
Watch Life OD they run cars on crazy things all the time. Baby oil, WD-40..
SRT8 MadMan when I was a kid we ran an old 2 horse tecumseh with peanut oil in it. Governor wide open & no load. It would sieze & free up as soon as she cooled down. Ran that way for maybe 3/4 tank of fuel until the rod let go & put a nice hole in the block.
Love engine parts made out of silly materials. More please!
Thank you!
Love to see strength test between various 2x8 woods and the new composition joist types they make today
Great video idea! Thank you
I made a head gasket out of oil soaked cardboard for an old Yamaha 90 dirt bike , it worked for a couple of years last I heard.
Thanks for sharing.
4:46 but flex seal can fix it
Great video idea!
*T H A T S A L O T O F D A M A G E*
You know, I wonder how one of these plastic cylinder heads would perform if the guy who sent them to you engineered them where the spark plug could still be screwed in with a recessed area while the cylinder head itself was much fatter and had cooling pipes running through it, connected to one of those PC water cooling systems or something that could cool down the plastic. Just makes you wonder. Seems the only reason the heads failed was due to heat.
TLDR - It would probably work if they made a high temperature plastic that could be printed, but that would probably be expensive!
Love the train of thought on that, I'm a PC tech so I kinda wonder the same thing. Though I feel like a big issue would be if the car overheated and either boiled the liquid in those lines or melted them leaking it out. The design would probably either be expensive due to the amount of materials needed to be efficie t or really cheap due to failure rate becauseit how hot the normal operating temperature is and other systems could cause the engine to run hotter than normal too. So it would probably just require a better material.
PLA melts with a hairdryer. It ain't gonna last regardless.
I can’t see it working. Plastic doesn’t conduct heat very well, so the cooling system wouldn’t really cool the combustion chamber enough... which is where the failures are happening.
You could make it with some high temperature plastics. It'd be more expensive than just going and buying the best lawn mower money can buy. And retarded when I could make it out of aluminum for a hundred bucks.
@@ebouwman034 I was thinking he should have put cooling fins on it, but then I thought of the heat conduction issue
TPU 95A makes really good gaskets and O-rings.
Would like to see one of these heads made from CF nylon, I prefer SainSmart 25/75 black CF nylon. Polycarbonate would be cool too.
Or maybe do a collab video with Vision Miner and have them print some heads out of PEEK and PEKK.
My Ender 3 Pro is running Marlin 2.0 firmware on a 32 bit silent motherboard, Micro Swiss direct drive and all metal hot end kit, BLtouch auto bed leveling probe, textured glass bed that is hard mounted with solid bed mounts. It'll print anything from PLA, TPU, and all the way up to CF nylon and Polycarbonate. Also, ASA is easier and better than ABS. PCTG will be replacing PETG soon too.
Thanks for the suggestion.
“That’s a lotta damage!”
Where have I heard that phrase before? 😂😂
