Great video as usual Igor! Love how scientific you are in all your testing. If I could afford it I would gladly support your work monetarily, but being unemployed I can not justify the spentiture at this moment. What you are doing for the community is very important. Keep the great work up and keep growing your awesome channel! Love from Sweden
Are there even printers for home users that can print PEEK without modifications? I mean just by the maximum temperature for the hotend, not even with the other things you mentioned. Apart from that a comparison between multiple high end materials for home users like nylon, PC, PVC, carbon fiber, glass fiber and maybe even PEI or PEEK would be really interesting to see
thanks for the test, should’ve tested the strongest and cheapest material of them all - steel (even mild steel)! seriously in that thickness I think it would outperform any aluminium, we use it a lot for boatbuilding in NZ
Pure PEEK is extremely difficult to work with. PEKK is expensive, but is easier to work with and has similar properties. Carbon fiber PEKK is even easier to print and stiffer too.
Some CF PEKKs can even be printed, inefficiently and poorly at the lowest recommended specs, on a Qidi Q1 Pro, a 450$ machine. You can, quite literally, print a single spool of 1kg filament more expensive than the actual printer.
An idea: creep depends on the strength of the material (loading aluminium and plastic with the same weight is clearly not equivalent), so what don't you always start doing creep tests using weights which resultin an instantaneous stretching of a predefined amount?
Yes, I was thinking about that too. But when I started this creep test, I was curious what material to use for one specific load which is the same independent of the material.
Yes, I checked the prices too now. PEKK is easier for printing but even more expensive. I will stay with ABS, PC, PA (+CF) if I will need something stronger :-)
Have you tested any Nylon 12? Everyone seems to just make Nylon 6/6.6, but a couple of companies make Nylon 12, it's supposed to be a lot less moisture sensitive, I'm wondering how it's mechanical properties compare to the more common 6/6.6.
You are right, N12 is less sensitive to moisture, but very expensive. I think I will get the whole PolyMide line for testing from Polymaker. I also have N12 from AzureFilm here, waiting for the review..
@@MyTechFun Yeah, it can be a bit pricy sometimes, Polymaker's is so expensive because they only make fiber reinforced N12, I really with they offered a regular one too.
Hi, Can you please help? I have designed a part in TinkerCad, exported as STL and with FreeCad I converted the part to a solid object and exported it as a .step file. I uploaded the file to PCBWay, paid them and after a day they told me that my part has many triangles and that I would have to re upload a file with no triangles... I am not sure what I should do. Any ideas? Thanks!
The first one is cumulative table, in earlier videos only this was presented. But smart suggestion from visitors was to calculate the creeping for each day (0=no creeping for certain day), and to present that (second table).
@@NicksStuff Theoretically they all start from 12mm gap (with no load). Anyway, excel table is given, so you are free to modify and recreate the table for own needs. But in future videos the absolute daily creep will be presented in graphs (the second table)

Kind words like this are also great support. Thank you very much!
Thanks for running this test! The Funmat HT is quiete famous for printing high temp. It is "cheap" among those types of machines
I have this printer at my workspace. it is really good for the price and the prints are very good. you can print pekk peek and pei
I love how you used your foot as an engineered safety device, LOL.
Great contribution. Thanks!
great video!
Just the video I was looking for, love it!
Thank you for your testing 👍
Great video as always
Interesting material test
Thanks for sharing your experiences with all of us :-)

Looks like no, just with some serious modifications.
thats some nice scaling on the tests! finally a peek & pom!
Very, very interesting. Surprised PEEK wasn't stronger. Wonder if PEEK w/ CF would do any better? Thanks.
I will test some CF filaments in near future, but not PEEK.
The peek is very stong but not stiff. The hook just bent open and then launched into space.
The CREATBOT F160 - PEEK VERSION is the only „affordable“ low entry printer I know to print peek.

Seems you didn't use the more premium versions of PEEK, which at least I intend to use. Some maybe don't need those requirements, sure.
Отличное видео!

Thank you Mark! It is good to see, that I was not the only one who was so curious about these materials :-)
@@MyTechFun Yeah I mainly focus on printing functional parts, so I find these types of videos the most interesting.

If you can get a sample of 7075 T6 Aluminum it will be significantly stronger than regular aluminum, close to double the the strength
can POM replce carbon fiber for drone frame?
Even if I could print PEEK, I would rather not because it is too expensive

Pretty sure teaching tech printed peek on a basic printer as a test. But probably not worth it because peek is like 500€/kg.
Good to know. If you will find the link, please post it here. Thx.
@@MyTechFun ruclips.net/video/OJGf-c0bzhQ/видео.html Must have been makers muse too who had one on peek
11:24 A CUMULATIVE creeping table would have been meaningful here

@@MyTechFun The first one shows, the gap, not the creep since they don't start with the same gap
