Вставка
- Опубліковано 9 лип 2024
- In this video all Polymaker TPU filaments are tested and compared with each other: TPU90 is the softest. TPU95 is hardest and HF means high flow, it can be printed on higher speeds. This is first detailed TPU test on Mytechfun channel, and suggestions about testing methods are welcome.

Honestly they are truly appreciated
Not many of us want to know such detail but those who do truly appreciate you.
Keep up the great work Doc 👍😉
Good lord the testing was exhaustive and beautiful! Thank you for the hard work!
There is a lot of great data there. Thanks for doing these. For soft rubbers, especially when designing vibration mounts and shock absorbing systems (dynamic systems), the vertical rebound test will test the material resilience (ASTM D3574-17 or D2632-14 or DIN 53512-2000 all test the same thing). You may even be able to use your Charpy impact tester to do this test but I just do the ball drop test because it is so simple. The resilience gives you a good indication of the internal losses during vibration which helps to damp out vibration. It also tells you how well a ball will bounce when you drop it.
I really liked the washer test and I agree with you Igor, it needs more revolutions; possibly even past 2-3X the turns you've made (6-10 turns). That was a great idea for testing.
For soft/elastic materials, I would also like to see the squish and spring-back of the materials, in Sudden Force (Shock). Like bump-stops in suspension, at the end of travel. You can do this by printing a disc of the material, dropping a known mass object onto it; and as a backdrop of you filming it, you can have a lined chart with distances to measure (like you do for the hammer swing test). Measuring how high the dropped object bounces back -> how much of that shock is Absorbed into the material.
I have no interest in 3D printing, but I can't stop watching your videos You're doing Great Work. 👍
I love these comprehensive comparisons and tests. Thank you for all the information!
Great video as always
Great test and giving an idea of the problems with the Flex filaments
Thanks for sharing your experiences with all of us 🙂
Another great video man!
🔥 great video!
Killer review! TY for sharing. :)
Love the title. I clicked on it before even knowing who it was. :)
Great video! very creative way to test TPU! One test that occurs to me is to stretch a sample a given amount and see how much it recovers, independently of the load needed to stretch it... lets say a 100mm sample you stretch it to 200mm and release and see if goes back to 100... maybe 130 and such. I am super eager to see the PA tests!! keep it up! :)
Needed this one.. Thank you
Thanks for the video! Interesting indeed.
great review ! thanks
thanks! very good job!
thanks for doing that ! :) good video
HF seems interesting since normal TPU needs to be printed so slowly, even my Bambu Lab X1C feels slow if I want nice results. I recently bought a very interesting flexible filament: Extrudr TPU Hard with a shore-rate of 58D, which is far stiffer than 95A and even 98A which they call 'medium'. It really delivered what I was expecting: Almost as structural solid as normal filaments even with low infill, but still TPU and flexible. I needed grips for my sim-racing wheel and TPU 95A was too soft with 40%% infill and several layers, but with more infill it prints forever and adds quite some weight. I choosed PETG with low infill, but want more dampening. I think there is a bigger market for this kind of hybrid-filaments, but only Extrudr seems to offer this shore-rates. But despite the hardness it didn't like to be printed fast on the surface.
Can you run that 58D through the AMS?
@@Eric_Wolfe-Schulte Not really. First it works without hassle, but than it got stucked after a few prints. The filament itself doesn't feel hard before printing, so not that different to 95A, that also doesn't work. I bought a dry box that stays next to the Bambu to print TPU and no problem feeding it directly. But seems it's necessary to unplug the AMS before.
Amazing testing as always! Very interesting to see :) I do have a suggestion for another test that could be very useful for TPU, the friction. These filaments could be useful for printing wheels or phone cases and in both of those scenarios it's useful to know how much effort it will take for them to slide.
Hm, yes, this is second very interesting tip for testing I got in comments (somebody suggested to test bouncing). If I will figure out some repeatable and measurable experiments, I will include it in testing.
Looking forward to the Nylon experiment. Love yr comparisons. That got me to eSuns ABS+ and I love this filament.
Nylon uploaded few minutes ago. ua-cam.com/video/cQb-hbr1KYY/v-deo.html
Thansk again Igor for such in depth material reviews. Eagerly wating for the PA tests. Please, can you ad to that video a brief description on what are the main diferrences between PA6, PA 6.6 Pa12 ans its uses in the industry. Thanks in advaned!
I will try, but not going to details. But I would suggest you this 3 minutes video, they explain it very good. ua-cam.com/video/dTWAJmWeGHc/v-deo.html
why didnt they include hardness scale in the name. i get my filament from manufacturer that labels them accordingly to scale. so at home i have 40D and 90A TPU. and i print them both at 100mm\s on my NF Sunrise
Thanks for tests! They are great!
Could you add oil resistance tests also? They can include size change measurements and tensile tests after some time of keeping details in oil. And some time after drying. Or some other tests. I'm not professional in this question.
Lol it is 41C here this week again, think I'm going to give it a shot on my unheated bed.
Could you perform tensile and shear strength tests on the filaments itself?
If these tests are possible, could they be related to the testing that you have presented today?
Thank you.
Here’s an idea. Cheetah in my experience has perfect layer adhesion. Why not make a CF/GF TPU? Better bridging and probably as stiff as PETG. But applications where your part needs to be semi-stiff and withstand constant shock May find some use for it.
I just got all Extrudr TPU filaments, which include carbon version too (introduced in this video at the beginning ua-cam.com/video/MjllKSVLY1s/v-deo.html
There is a fabricator from Spain called Leon3D that has "hard semiflex", TPU that they promote as better than ABS
Do you think that 93A Shore can be used for industrial anti vibration mounts?
HF was uv resistant right? I thought that was an important property. Good video. I subscribed to the channel after having seen a popular short.
Do you think TPU would beable to be printed clean (without much stringing etc. and after work), when thinking about doing serial prints with fdm printer?
Fan!
You never mentioned fan, did you pay attendtion for it? For better stringing And expecially for bridging is setting fan heigher very helpful.
However, Thank You for setting up this new Series "TPU"! Looking forward to see more of this.
I mentioned it at the beginning, when talking about specs which I followed. FAN ON (100% or 255).
Excellent review! Which of them is better for timing belt usage?
From these TPU95-HF. But I got several suggestions to test timing belts from nylon. Test comming soon.. (few weeks)
Sorry Dr., my questions correspond to the video,
16 PLA Brand Comparison Test - Which is the Strongest? Part 3/3
Can you please ad the link to the durometer?

Hi! Do You speak hungarian also? If yes why not annotating Your video in an other version
I have a Hungarian channel too, but not too popular, most of new videos are published there too: www.youtube.com/@3dnyomtatas
I heard the Ender S1 pro is excellent at printing TPU, maybe try it out, I think you will see a big improvement.
It would be better if there was a test for friction, since TPU material will be used for tires and such.
Yes, I prepared one, I will be presented in my next TPU review (and I will re-do with these polymakers too)
Strange how much stringing you have. I have Ender 3v2 metal extruder, bowden, all metal hotend. Tried 3 brands of TPU. Minimal stringing. You have a lot of stringing...
Yes, I noticed that too when I reviewed SV06 using same filaments (can be seen in video). I have to investigate the problem..
