- Test of all 4 Extrudr TPU filaments: - Hard reinforced with carbon fibers (58D), - Flex Hard (58D), - Medium (98A) and - Semi soft (85A).

For the CF version I used 0.6mm hardened nozzle it is printed on Prusa MK3S. Other 3 TPU materials were printed on newly assembled Prusa MK4.
I noticed that it is very important to dry the filament (even if it is out of the box), but for this any cheap filament dryer is good enough (I used eSun eBox for this)

Yes please include the friction test in the future!
Thank you for that.
"pops" or "crackles" might be more widely understandable than "cracks". Thanks for another great video.
OK, thx for the lesson, I will try to remember this. And what about "crack sounds" ? :-)
@@MyTechFun Personally, “crack sounds” isn’t understandable either (at least to a native English speaker), but ‘crackling” or “popping” describes what you’re hearing pretty well. Also, great video, love your content!
A cracking sound would be like a gunshot or thunder. If your filament starts making one of those it might be a good idea to run away very fast!
Thanks for all the hard work.
the friction test is very interesting, I'd be interested in the puncture resistance of the material, similar to the isod impact test but just specializing the sample and method of impact to take into account TPUs properties
Yay, I've been waiting for this ever since I saw them in the other video :D
Thanks for all the thorough reviews you do!
I think the friction test is an interesting idea, especially since that's a common use case for TPU.
What I would like to see are the results you get with the same methodology with a standard PLA or PETG filament, for reference. (No need to include it in all tests for those types of materials, just once to see roughly how they compare to TPU in general)
It would be a great series if you would test less known type of filaments, esp because its really hard to find those on CZcams. For example PMMA which seems like have very good properties, does not require high temp (medium) almost as cheap like PLA. Probably closed chamber. Or POM, which is a really good choice for sliding parts
Good info, I use Extrudr filaments a lot, and like the Durapro ASA Carbon, and GreenTEC Pro filaments. I've not used Flex Hard yet. I did manage to use the CF with 0.4 but changed to 0.6 very quickly on my Bambu X1C.
There are two things, which are absolutely crucial to get good prints with TPU:
1.) Drying. Filament needs to be totally dry (
A good array of tests ... thank you.
Thank you for the tests. However, for our specific use, I would like to see abrasion resistance and impact resistance tests
Ohjeah!
I waited for this review! 😀
you should measure both static and dynamic friction
It looks like you need to speed up the bridging speed and maybe lower extrusion amount on first layer of bridge as well.
Can you do a test where you do a 1” or cube and then load with 20kg to see how much it squishes over time. Basically a compression test over time. And a compression test to failure would be good but I guess it would harder to accomplish at home easily..
Just curious as most test you do are tension tests not compression,
The washer test and one of ring tests are about compression too. Washer measured after 1 day compressed from 15 to 12 mm.
Blue pigments can do weird things to print quality. That might explain the lower quality of the medium hardness filament
Friction / Air Moisture (Humidity)
First of all, I'll let you know that it has nothing to do with the channel, it's just a rant about the world of 3D printing.
Today, I bring a different perspective on 3D printers, based on the research I carried out.
I came to a conclusion that I would like to share.
I have a comment about the world of 3D printing, which, contrary to what some say about accessibility, is still a world for few. Despite the criticism I may receive for this, I believe that although printers have become more affordable, there is still a long way to go before they become an achievable dream for many people, including myself.
It's not just the initial cost of the printer that must be considered. An often overlooked point is the ongoing cost of the filament. Just like in the early days of inkjet printers, where the price of ink was an obstacle, today we face similar challenges with filament. Even though printers have become a little cheaper, filament remains a considerable investment.
It is notable that over the years we have not seen a significant reduction in filament prices. There appears to be a lack of real competition, resulting in companies setting prices almost like a monopoly. Filament quality is also a concern, with reports of poor quality not justifying the investment.
Another aspect that is rarely addressed is the amount of material wasted due to unsuccessful prints, especially for beginners. Even though errors decrease over time, they do not disappear completely. This is a relevant point to consider, as it contributes to additional costs and not to mention environmental issues.
That's why I say it and I repeat, cast the first stone if anyone who has never been through this, even with vast experience, still continues to print with errors and has to do it all over again, no matter the printer or your knowledge, there will be errors and as a result waste of material and input costs. what do we need and start thinking about this issue, well the filament should be cheaper, it would help the person who bought it and nature thanks you.
antes de qualquer coisa ja aviso que não tem nada a ver com o canal é apenas um desabafo sobre o mudo das impressões 3d
Hoje, trago uma perspectiva diferente sobre impressoras 3D, baseada nas pesquisas que realizei.
Cheguei a uma conclusão que gostaria de compartilhar.
Tenho um comentário sobre o universo da impressão 3D, que, ao contrário do que alguns afirmam sobre a acessibilidade, ainda é um mundo para poucos. Apesar das críticas que posso receber por isso, acredito que, embora as impressoras tenham se tornado mais acessíveis, ainda há um longo caminho para que se tornem um sonho alcançável para muitas pessoas, incluindo eu mesmo.
Não é apenas o custo inicial da impressora que deve ser considerado. Um ponto muitas vezes negligenciado é o custo contínuo do filamento. Assim como no início das impressoras a jato de tinta, onde o preço da tinta era um obstáculo, hoje enfrentamos desafios semelhantes com o filamento. Mesmo que as impressoras tenham ficado um pouco mais baratas, o filamento continua sendo um investimento considerável.
É notável que, ao longo dos anos, não tenhamos visto uma redução significativa nos preços do filamento. Parece haver uma falta de concorrência real, resultando em empresas que estabelecem preços quase como um monopólio. A qualidade do filamento também é uma preocupação, com relatos de baixa qualidade que não justificam o investimento.
Outro aspecto pouco abordado é a quantidade de material desperdiçado devido a impressões mal sucedidas, especialmente para iniciantes. Mesmo que os erros diminuam com o tempo, não desaparecem completamente. Este é um ponto relevante a considerar, pois contribui para custos adicionais e sem falar das questões ambientais.
por isso falo e repito , atire a primeira pedra quem nunca passou por isso ,mesmo com uma vasta experiência, ainda continua imprimindo com falhas e teve que fazer tudo de novo , não importa a impressora ou seu conhecimento , vai haver erros e como consequência desperdício de material e gastos com insumos. o que precisamos e começar a pensar sobre esta questão , poxa bem que o filamento deveria ser mais barato , ajudaria a pessoa que comprou e a natureza agradece.
