2:33 It's crazy when you set the part down it sounds like metal, hahaha. Wow drying the filaments makes a big difference in the updated spreadsheet. Strange the lowest temperature printed PPS-CF has the best layer adhesion. The Polymaker prices are actually pretty reasonable, so I may try some of these, especially for future automotive projects.
By the numbers, these exotic filaments often hardly look better than PLA. But man, print kids toys in them and you quickly see the difference in durability. I printed pirate ships for my kids in two sizes using PA6-CF. Haven't broken yet. One has been out in the yard for like 6 months and I saw them ride over it on the power wheels. The sails broke immediately on the PLA ones the second they were dropped.
On the surface with just the limited testing I have done, yes, the numbers indicate that there isn't much better about them. However, there are multitudes more parameters that I do not have the lab equipment to test that show where each of these excel. As for being tough, exactly right, the limited testing might say X is only marginally better or in some cases not as good as Y but in RW applications X is superior and Y isn't then another RW scenario where Y is the only one that will work and so on. You want tough, print toys in a hard TPU and watch kids try to break it.
Hello! Thank you for providing this strength testing data for us, as you seem to be one of the only youtubers I see with access to this material at the moment. For both PPS-cf and PET-CF, this main source of popularity is their heat resistance AFTER being annealed. Would you be able to conduct a basic HDT test regarding this after annealing the samples? As I stated before, the flexibility of filament concerns me in that the base resin (ignoring the cf for a second) could be blended with other lower temp/more flexible materials that will affect the pet's ability to crystalize. This would lead to a lower HDT than other PET-CF filaments already on the market, making polymaker's PET-CF and PPS-CF pointless for applications requiring higher temps. Thank you :)
I'm working on that at this time to get some solid testing done with regards to annealing and heat testing. Mind you, I am a content creator and not an engineer/scientist, so these tests are largely subjective and by no means meant to be lab quality testing. I take the approach of designing my own test equipment and going at it from a hobbyist/maker approach and not an engineer or scientific. And, yes, I am extremely fortunate that Polymaker trusts in me enough to supply me with pre-market samples to work with. I hope to have a bunch more results to share before the 25JULY public sales launch.
Well done on testing these out. That PET-CF is surprising! I will say that your peace sign has the right vibe, though if you did it in the UK, you might get yourself in trouble. 😂
It's actually my adaptation of the Scissor gesture I learned while I was in China except I do it palms in not out because supposedly people can steal your fingerprints according to Chinese government.
Great video with good results. Love the test rig you put together. I hoping to find the video of how you put this together but didn't see it on your channel. Possible future vid????
Yes, there will eventually be a video. Getting the testing started ahead of the public sales launch was higher on the priority list than the how-to for the tester. It's all custom designed/printed so I have some work to do before releasing that video because everyone will want the files and they are not in any kind of shape to release.
Many people are interested in glass and carbon fiber filaments not because of material properties but because of the print finish. Please include many closeup shots of printed items in your future videos. This will only help.
I'm making more videos where I will show print quality. Right now, I'm focused on materials testing as most people are not going to spend $140 kg for a material just based on print appearance.
Interesting that PET-CF actually beat the PPS on layer adhesion and came close to it horizontal, plus has a lower printing temp. Judging from the “clink” the PPS-CF makes when it hits a hard surface though, I’m guessing that it’s _way_ more rigid. (Very high bending modulus.) I guess another plus is that it has such a high temperature tolerance. I just wish my X1C could go to 340C 😕
If you watch in the video's where they break, most of them bend a little (or lot) then just kind tear then snap but the PPS-CF does not "give" at all then when it does fail, it's explosive in nature. It also breaks leaving VERY sharp edges, much like shattered glass. I had a part fly off the tester and sliced my arm open like a razor blade.
More testing underway, currently building a Izod testing station for Impact strength and working on a couple other things like a pullout test for heat set inserts and for longer term, some weighted pullout tests and deflection to test for "creep".
@@EDGEOF3D Some temperature resistance testing would also be great! Usually that's why I anneal parts, for the resulting higher resistance to deformation in high heat.
Working on that right now, the PA12CF just finished printing with a RH of 12%, the PET-CF is printing right now showing a RH of 18% (currently on the dryer, once I remove it, it will drop to 10-12% after it cools).
Do you know if Polymaker bought out XYPolyer's PPS? The timing is very coincidental. I used to buy their PPS-TF (nobody knows what the "TF" stands for) but they pulled it from their page shortly before Fiberon PPS-CF dropped. Cool stuff but now the price is insanely expensive now😔
I doubt Polymaker bought out anyone's line, they are one of the very few real filament manufacturers in China. Polymaker is not the only thing they make; they produce filament for a large number of companies.
There are pretty solid guides on modding Prusa machines to print at higher temperatures. I believe PT1000 temperature probes are readily available for it and you may want to upgrade your heating element so it doesn't struggle to maintain temperature. I believe the hotend and heatbreak are all metal, so you're good to go there. Will probably need software mods as well, though I'm not familiar with the procedure on Prusa. Either way, a few $10 bills and some time and you'll be able to, I believe.
"We" are not doing anything, however, this is my channel and as such I can do whatever I choose within YT terms of service and last time I checked, thier TOS makes no mention of wet filament.

I'm glad you said they weren't available yet when I searched the metrial I would get errors

@@EDGEOF3D Printing toys is my test-n-tune for when I print my own "toys". ;) CF Nylon seems to be a sweet spot between stiff and tough.
Great video Scott, thanks for the info.

@@EDGEOF3D Def excited for that! The PA6-GF is very interesting to me at the $30 price point. Would love it if you could test that at some point.
I have a roll coming and will add it to the testing.
I only use the cf version of this or that for appearances is when I still need all of its other properties

Temperature testing is in the works.
What printer are you using for these temps ?
Trident with Rapido hot end.
Good vid. After you dry all the filament and run the tests again can you put all the result in a chart?

Is the PPS-CF as difficult to stick to print beds as Polypropylene (PP) ?
I've not had any issues with it sticking.

Why are we even doing this video with so many wet filament prints and missing filament tests because the roll was wet?
