I teach a small engine high school class that uses donated junk equipment. Most of the donations are out dated and in some cases parts aren't available anymore. I'm using a 3D printer to make all sorts of parts for students. In most cases, our parts only need to last about 30 minutes. If they last longer, then all the better. I'm using TPU to make a variety of carb and carb bowel gaskets. The big key is just what you said about another tool in the toolboxes. We can make a gasket faster and cheaper than seeing if we have a budget left, then trying to order parts, and finally hoping to get them in time. The 3D printed gaskets and parts are made quickly, teach kids design, and cover an enormous range of equipment, making our program more successful. I'm with you.
Good to see you again Eddie . Deepest condolences mate , you know he'll always be proud of you.
Thank you my friend!
I appreciate your recognition of printing casting molds. Most people don't realize that printing opens doors other than just printing plastic parts; molds, cutting and bending jigs, and even negatives for ceramic molds for high-temperature metal casting are all possibilities for home manufacturing of various tools.
Hello, thanks for watching and hearing, lol. Moulds are something that I have not messed with much yet but plan to. They are definitely a much better option for some applications.
Hi Eddie. I'm a mechanical engineer in New Zealand and am looking into additive manufacturing options for producing gaskets internally with my company. Your videos are informative, and I've learned a lot from them as I've only printed with PLA and ABS before. Thanks for the great video, its well-produced and written, and you're making a great contribution to learning with videos like these. All the best with your future workshop endeavors. Cheers mate
Cheers! Brody. Thanks, much appreciated.
These type of real world test in my opinion are much more valuable than many "scientific" tests. Thank you for your videos on this. I've been thinking about using these as gaskets. (hence finding your channel) I've made a couple gaskets for the wife's wine type bottles that get put in the refrigerator and work wonderful. Keep up the great work and sorry about whatever happened. Have a good day.
Yes that is something I have not even touched on but the uses around the house for TPU are endless. I made some lids for open cat food cans for my wife. Much better than the cheap ones bought at the store. They seal well and are easier to take off an on. I have used it for a bunch of little things like that. All the best!
@the_eddies I agree, I've also used it for these aluminum "solo cups" that we have, it works great, just have to remember to put a little vent hole if you're using it for anything hot and/or carbonated. Lol.
And I've also used it for gaskets on some custom windshield brakes on my side by side. There's so many uses, we're just touching the surface.
@@paulm1835 "just touching the surface." agree completely.
Great video. I just had to print a gas cap for a lawnmower out of pla but did not build in the vent. I like your vent idea. Thanks for sharing. Glad to see another GA creator.
Thanks!
I don't know what you are going through, but may God give you peace and be with you through your days. I'm very glad to have run across your channel. I just received my first printer today and what you have on your channel is exactly the type of things I had in mind when purchasing it. So, thank you for your great videos and inspiration and know that you have been very helpful, at least to this guy.
Thank you!
I love blokes like you mate. And things like this is exactly why I got into 3D printing. You are an absolute champion and an inspiration. Thanks for all your time and I loved your findings.
Pete from Australia.
Thanks Peter! I really appreciate that man. Cheers! Eddie
Gday Eddie, sorry to hear of your loss mate, I was only thinking I haven’t seen a video from you in a while not long back, I’m impressed with how the gaskets have held up over the year, there brilliant results I believe, hope to see you back again soon mate, cheers
Thank you Matty! I am slowly getting my feet back under me. Getting back into it would be good for me I think and it is what dad would want, he loved watching. We even watched a few of yours in hospice. Despite my gravel voice this felt good to do.
Stumbled across your YT videos on TPU. Great work man, forget the haters. You did a lot of solid work on this and really gave me a lot of good information on your annealing of TPU. Thanks!
Thanks! Your arc welder video is one I have saved for reference and made a big difference in my regular prints. Thank you!
Thank you for the great videos. Appreciate all the effort you put into testing these TPU gaskets
Thanks!
That's a very interesting experiment. Always good to know. Thanks for doing this.
Hello Rusti, thanks for dropping by. Hope everything is well with you.
Excellent content and good job making really useful parts with 3D printing! So much nicer than looking at how fast someone can print a benchy boat. Keep up the good work!
Thanks! Much appreciated.
Sorry for your loss buddy! Absolutely fantastic testing and results.
Thank you! and thanks for watching.
thanks for this research, i have some TPU and never thought of using it this way.. great use case for it..
Love the follow up thanks for doing this. I'll be using TPU in the future for throttle body gaskets since it gets pulled for valve adjustments in the hotrod often enough that the regular gaskets get brittle and fall apart!!
Sounds like a great use. Thanks!
I learned a lot with this series on TPU gaskets, thank you.
Thanks! All the best!
Thanks for this! Glad you took the time. I had been wondering about applications on engines.
Thanks! Glad you got something out of it.
Condolences on your loss brother, great video follow up! good conclusions! thank you.
Thank you!
Great vid, thanks for the follow up!
Thanks for watching!
That’s really cool. I love to see the one year latter update. Yes, my friend, life is too short for things that don’t make a positive difference.also, too short to keep repeating things as you said. Thanks for the informative video
Thanks so much. Glad you enjoyed it. All the best my friend!
Great test, it answers a lot of questions that I had myself. I have found data sheets that also state that TPUt works well with gasoline. thanks again for your time and effort!
Thanks!
Awesome video. I was curious how reliable TPU would be. This video exactly answered my questions.
thank you for the video and information
You gave me good ideas with 3D printing the mold and use high temp silicone 🎉
Thank you for the lovely video with real life testing! Eddie
Thanks for watching!
Great info and testing! Thanks so much! So far my TPU gaskets haven't been liquid-tight, but I think it's due to my settings and I will check out your other videos for answers there.
Hello, thanks! Might try increasing flow a little and or smaller layers. Best!
Loved the video, loved your comment! 😀 Getting ready to print some parts for myself now!
Thanks!
nice work...just seen the original gasket video you referenced and love the follow up! I had already thought about making my own gaskets and thought they wont work it gonna be too hot and all but i didn't think about carb and other lower heat uses especially the gas jug lid.
Thanks! They are all still in use. All the best!
Thanks for the highly useful information!
Thanks for watching;
Wow I'm really surprised it held up so well and especially with direct contact with petrol thanks for the video it was very educational for me as I was interested about real world use of TPU for these types of applications 👍.
Thanks!
Hi Ed, good to see you again, regards Del.
Thanks Del! Good to hear from you. Hope you all are well.
As an added data point, I printed thermostat gaskets for my boat out of tpu. I printed 2 (twin engined boat). It’s been over a year with no signs of leaks. I just replaced the thermostats and reused the same gaskets. They were perfect when I removed them and they’re still leak free.
I've found it useful and thought about its different uses, in my case I did a sim for a bearing on a rocking chair which gets a lot of use e.g weight load and rotational load. yea it'll never be as good as an original piece but if needed I just print another off. got a few niro RC cars which need gaskets which I might try.
TPU is extremely tough, it might be as good or better than the original. I would be curious how it holds up against constant use with variable loads. Another video maybe, lol.
Just found you gonna go back and catch up hope the content continues
I have recently wondered about this so it's great to see someone doing live tests. It would be amazing if they held up to higher temps because it seems that's one of it's main downfalls. Which would be my thoughts given it's glass temp being around 100c
How ever it's great to know, as i own a lot of tpu, a few 3d printers and a few things with engines in them.
Keep up the great content!
Thanks!
people on the internet are the most toxic ya ever meet. I'm sorry for your loss. great to see you back, and hope to see more experiments with tpu in the future, you're the guy who got me into working with tpu and I've been finding excuses to use tpu when I can haha. best wishes to you mate.
Hey thanks Kevin that means a lot. For every one of the trolls there are more good people like yourself. All the best!
On the engineerig side of things, TPU is a high performing material for a gasoline exposed gasket.
TPU also has good oil resistance. So, these results do indeed follow the engineering and chemical reaistance charts.
The largest complications are printability, UV stability, temperature resistance, and porosity.
Great job proving this out in the real world!
Thanks! Even with all the data out there on TPU, I think there is also a lot of misinformation. That combined with the amount of filament manufacturers that do not provide enough information on their product's specifications made these tests necessary, at least in my head, lol.
Great to see.
Hey Dan, good to hear from you.
Thanks for sharing. Good to know some more uses for TPU. One test I'm curious to find out is low temp performance. Typically the majority of plastic parts fail at -50C but many fail way before that. Too many ppl try to use structured cores instead of solid infill for structural parts and wonder why they fail... ROFL
Hmmm.... Interesting idea now where to get liquid nitrogen???
Thanks for continuing this and sharing the results/observations.
Has the fuel in the jar been refreshed/added to?
I'm wondering if there is a very small fraction that may have an effect has already saturated or evaporated.
Hello, the jar was not added to since the time it was sealed. I opened it once a few months ago for a few seconds just to check the parts, but other than that was never opened. I considered a frequent changing to fresh gas, oxidation factors, etc. but really do not have a way to control for those factors with any precision. The use in the gas tank is the best I can introducing environmental and normal use factors. Thanks!
Hey bud, love this video so much! I was wondering what brnad of TPU this is?
Man I hope you’re alright. And thanks for the video!
I am ok, thanks for asking.
This is the first video I have seen from this channel. I'm sorry for your loss!
I was honestly just wondering if any one had made seals or gaskets using a 3d printer before. I'd probably be too sketched out to do it on a motor, despite your positive findings. Pretty cool though!
Thank you! I still would be hesitant to use these on anything critical but there is some uses out there. All the best!
What's impressive is that you have replacement gaskets in less time than it takes for them to ship. This is just the beginning, I'm sure there'll be ways to 3d print without using heat.
Just came to your channel, and love it, i got a 3D printer and it never dawned on me that i could print things like that…
Thanks! All the best!
You should look into some nylon based filaments. Polymaker and Taulman are two that I would recommend. Taulman has a lot more nylon offerings than Polymaker.
Thanks a lot for taking the time to share your experience with TPU after a year of use. I see you dont recommend it for applications where temp surpasses 90C. Although i would like to make some gaskets for the radiator of my car. Do you think there is a small chance of success?
You are going to be right at or just over the 90C, probably not going to last long. Once it reaches deformation temp it is going to stay deformed. I would not on my daily driver. On a test vehicle I was just having some fun playing with I might try it. There are better alternatives though like silcone gasket material or 3D printing a mold to form a silicone gasket.
thank you so much for these videos i am currently making my own gaskets for my motorcycles carb bowl and was wondering how it would hold in the long term and having a year of use with little deformationb or damage is a great sign. most gaskets come in a rebuild kit and i build a collection of rubber, printing the exact gasket in 5-10 minutes for insanly cheap is incredible for me.
Still going strong after 2 years now btw.
@@theeddies great to hear
So, as I understand, I could safely use a TPU gasket as a seal for something way less demanding application: a gasket-frame mounted around a little LCD display to avoid rain/humidity passing into the case and damaging the electronics.
Also the outdoor temperature range in winter/summer should not be a problem (let's say from -15 Celsius to +40 Celsius). I'm right?
(My condolences for your loss.)
Yes, normal weather temperatures are not going to effect it. That sounds like a great use. Thank you!
Well time to 3d print tpu clutch shoes liner experiment
Thanks very much for sharing your results specifically about the OHV cover gasket. Can you share the cad file for the gas cap gasket? I don't think I need one but I'm interested in the design of it since I like to repair mowers of a types. Take care.
Sure, give me day or so and I will upload it to Thingiverse and Printables. I will send you a link when I upload it. All the best!
I am sending you a link in another comment. Sometimes links do not work in the YT comments. If you do not get it, send me an email. My address is on the ABOUT page of my channel.

@@theeddies got it!
That lawnmower valve cover! Is that Honda GXV 160engine? Last time I was trying to unstick a sticky valve, I had to use silicone...blah I hate this stuff, since the service (where it was just few hours before) used a ton of this and made everything smeared by it...
It is a Briggs but Honda would be about the same. The printed gasket makes it so easy to do valve adjustments. No cleaning and getting a new gasket every year.
@@theeddies that is the exact reason, why I love 3D printing... It can help keeping things running!
How do you think this would work for an intake manifold gasket on a V8? It would have coolant which may reach 240-250 degrees F, up to 200 degree oil, and fuel to deal with.
If it is an engine to experiment on and you don't care if it blows up, go for it. At 240-250 I think it would get too soft and lose the ability to hold torque. Maybe with some stiffeners like a two part gasket. Still that heat is way over my personal rule of thumb temp of 90C. Best!
Whoa! This one got camouflaued in my feed. There should be a name for that effect of a video blending in among others and kind of hiding in plain sight.
The thumbnail is too dull. It took longer to edit than I thought and I got lazy at the end. I will likely change the thumb soon.
@@theeddies Eye catchiness could certainly have a lot to do with it, but I think there is a natural blind spot (for me personally) which is the left side second row of my feed. Not surprising that is exactly where yours was sitting too. I tend to look left to right across the top for newest vids, and I guess by the second row I'm plumb tuckered out visually lol - Better kick that cold!
@@johnstrange6799 So I now I need to not only try to increase CTR, Homepage impressions, etc. etc. but also the fight for row position, lol.
@@theeddies lol yep Pole Position. I think people actually do do something to that effect by changing the video title and thumb a few times during the video's cycle of being new.
@@johnstrange6799 If you have enough subs (like 10's of thousands) you can do things like A/B a couple thumbs because you can get enough meaningful data pretty quick about which one is being clicked more.
I've been thinking about you, hoping the new job you had going was keeping you busy, but fearing what was. Sent a prayer your way every once in a while. It's been almost 50 years since my dad passed and I still miss him. Still hear his voice in my head, usually saying "get to work you lazy cull".
Looks to me like your tests are a complete success, swelling and distortion of the gasket soaked in fuel would have been obvious after a couple of months, if you've ever tried rtv in a fuel system it fails faster than it takes to clean-up the mess. I wouldn't consider the valve cover gasket a failure, cork and fiber gaskets take a hard set after a short time and eventually leak. Neither are re-usable without some kind of sealer.
I've started using silicon gaskets for the rockerbox covers on the airplane, they're re-usable several time, but even they fail after while.
Look forward to more of your posts, it's good therapy.
Hello Carl. I appreciate it. Job is still ongoing. I have actually grown their YT channel over a 1000 subs in less than a year. And yes I can hear dad telling me to "get off my lazy..." everyday, lol. This was good therapy, I agree. I have not seen anything from you in a while. Figured you must be busy flying and building. All the best!
@@theeddies Spent a little over a month playing with my new grandson in Florida, been home for a couple of weeks but the shock of going from 90degs back to 35 degrees took it's toll and I've been down with a cold/flu. Feeling better now so back at it as soon as I get my taxes done. Start flying Thursday
@@psgflier I am just getting over the sick as well. I am sure you could hear it in the video. We did not get much winter in the southeast this year. I am not sure it got as low as 35 at all. I guess that new engine is doing ok?
@@theeddies Funny how the weather was well above normal below a certain line and well below normal just above that line. Florida was much warmer and drier than normal.
Engine is working great, I can tell the difference, stronger and smoother, hardly wait to get back in the air again
I may be here be for the gaskets but hope you're doing ok, life sure can suck sometimes.
I am ok, getting my foothold more everyday, this is part of that process. Thank you! And yes life can really suck but it is all we have.
Try TPE which is a bit more flexible
I would like to try some TPE, but 95A is plenty flexible for these gaskets. Would be nice to make custom o-ring type squish gasket though.
My only comment is I would not consider the valve cover gasket a failure. Premade "rubber" gaskets do the same thing over time. I agree with a solid print being better, but consider the one you used as a good version, just not the best version you could make.
Thanks!, yeah "failure" was probably not the right word. Maybe, "less than satisfactory iteration". The reprint has been on there since without issue. All the best!
@@theeddies Thanks, and thank you for doing this post. I use an old commercial Honda mower that getting gaskets for is a pain. I pull the carb and clean it every year. Couldn't get a gasket in time last year and they are paper. I re-used it and it held up fine, but now I can go with something better. I appreciate the testing and the videos very much.
I also work in industry and we've had some rubber seals deteriorate on some enclosures that are in harsh environments, and the manufacturers do not sell replacement seals/. So I'm going to give TPU a try in those applications.
nice, thanks!@@swdw973
Nah man life punches you in the gut, kick you in the nuts, and smacks you in the face, all while asking you. . . . "why are you so upset bro?!?" . . . . I get it.
Thanks man!
@@theeddies Nobody warned us that getting older sucks a**!!!!! Take care man!
Thanks for the update. Seems like geriatricide to me, not to be rude, though I have to be on the defense with advocacy of the concealed wireless assault weapons issues where many shy away from or completely ignore. Thankfully, with my work the "Havana Syndrome" and "Health Attacks" situation came out and with way more bs controversy than needed since prior generations of men wanted the tech to be know way back who knows when like at least the 50's and 60's when started rolling out and maybe earlier when looking at the not steam rolled Navy. All the best and thanks for sharing and keeping up on this. Neat stuff.
Thanks! Best to you as well.
Has someone who is posted a a tonne of stuff on 3D printing on places like Reddit, it really is a situation where you know that the internet is going to pick apart your project or print down to the atoms and say that it is absolutely going to fail. They do this every single time and I would say around 98% of the things don't fail. 😅 I can't how big are pain in the ass people probably were
That sounds about right. I appreciate constructive criticism and I got a lot of that along the way as well. But yeah, there are a lot of people who never try because they believe something they read at some point in the past and never researched it farther or don't understand the point of doing it in the first place. It is ok though, because there were a lot of people that enjoyed it and many that were inspired to try some new things with the extra knowledge. Thanks for the comment!
@@theeddies yeah the big thing for me that I decided was that I would take what they say as useful, but because I had already created the part I would just run with the part until it fails. Often I think that they are correct about something, but that the severity of the problem isn't right. 😅 I do try to keep their criticisms in mind when it does fail though.
You think peek could work?
Never used it but isn't it hard?
Can’t you make a gasket out of anything as long as the material can handle the environment and the tolerances are within spec?
@@Dragondezznuts Yes, but the point of a gasket is to conform to uneven mating service and seal them. There are hard gaskets for certain situations but most will require at least some amount of flexibility to be effective.
@@theeddies your right.
