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.

@@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!
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,
It would be a great series if you would test less known type of filaments, esp because its really hard to find those on RUclips. 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.
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)
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
Amazing video!
Thank you for the tests. However, for our specific use, I would like to see abrasion resistance and impact resistance tests
Friction / Air Moisture (Humidity)

you should measure both static and dynamic friction
"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!
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.
It would be a great series if you would test less known type of filaments, esp because its really hard to find those on RUclips. 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
It looks like you need to speed up the bridging speed and maybe lower extrusion amount on first layer of bridge as well.
There are two things, which are absolutely crucial to get good prints with TPU:
1.) Drying. Filament needs to be totally dry (
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.
Blue pigments can do weird things to print quality. That might explain the lower quality of the medium hardness filament
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)

A good array of tests ... thank you.
Ohjeah!
I waited for this review! 😀
Yes please include the friction test in the future!
Thank you for that.
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!
Thanks for all the hard work.
