Update: Siraya PPA×3
Added 2025-03-07 22:19:48 +0000 UTCSpreadsheet is updated, new 3 lines: Siraya PPA, PPA-CF and PPA-CF Core (attached to this post).
What is in the progress (and I can see the end):
BambuLab PC-FR
Polymaker CoPE
Qidi PLUS 4
Just a reminder: Tomorrow, March 8th—don’t forget to print something special for your wife, girlfriend, or mother! 😉

Interesting. Looks like the core is the way to go. Almost stronger in every stat over bambu's offering of ppa cf. Looks like bambu's is a bit stiffer, but not sure if the stiffness alone outweighs the better stats overall along with the price.

2025-03-30 12:36:36 +0000 UTCWhile his video was a shamless clickbait, I think the concerns are legitimate. The analogy of wood is interesting, and could be popularized. But I would rather see more scientific comparison.

2025-03-12 15:00:12 +0000 UTCAh, again that video by NBR. If you rub it against your skin, the wood will leave more marks. Do with CF whanevery you would do with the wood. But for your question: Core is the best, then GF and then CF.

2025-03-12 12:23:42 +0000 UTCI already tested several hard TPU materials, and I mentioned few times that their advantage is not in flexibility but in toughness and wear resistancy. PP looks interesting, I will test some soon.

2025-03-12 12:19:03 +0000 UTCI would like to see comparison which material leaves more fiber splinters in the skin. GF vs CF vs CF/GF core - especially after printing.

2025-03-12 12:18:54 +0000 UTCYes in my testing 300c and zero part cooling seems to be as good as the layer adhesion gets with Bambu pa6cf. I tried up to 320 with a heated enclosure with no measurable improvement. The table and all the info you’ve given out is awesome btw! You have the best 3d printing channel on YouTube. I was just wanted to point that out because I bought the Sirya ppacf thinking the layer adhesion would be better than the pa6 and it wasn’t.

2025-03-11 04:27:43 +0000 UTCSince you are always looking for the next toughest material, I thought I'd point you to this video [https://youtu.be/GMxPsSA0pHc?feature=shared] about which filaments are good for small combat robots with a weight budget. PP seems to stand out as being tougher than TPU at the same weight. It could be really interesting to see a comparison of "tough" filaments normalized to have the same weight, probably best achieved by changing the infill densitiy and keeping the outside shape (part geometry) the same. Just and idea. :-)

2025-03-08 21:22:11 +0000 UTCYes, I expected it to be higher as well, but others have only been 5-15% higher than their unfilled twins. I wonder if it's the very long fibers Siraya uses that make such a big difference. It was also printed slightly hotter, another variable, I suppose.

2025-03-08 11:50:44 +0000 UTCNice review. It was handy to see the 2 CF options compared together. Thanks for the Hook test too, its appreciated. I'd love to see those 2 materials printed at higher temps, Its a pity there's not many consumer options for printing above 300° yet. Even the new Prusa is only 290°.

2025-03-08 09:21:26 +0000 UTCMy settings are always visible in the video (usually before 3D printing part). 300°C PA6CF? Definitely, something I want to try (together with nozzle diameter 0.4 vs 0.6mm)

2025-03-08 07:15:43 +0000 UTCI am not surprised about the temperature resistance. CF versions always have higher heat resistancy. I am surprised about some other properties, like layer adhesion or impact test.

2025-03-08 07:11:46 +0000 UTCIf you’re curious I got roughly double the strength in the z direction by printing pa6 cf at 300c with no part cooling vs the stock settings from Bambu.

2025-03-08 05:29:22 +0000 UTCI tested both Bambu lab pa6 cf and Sirya Tech ppa cf core filament a few weeks ago and didn’t seem to get the same results when comparing the two. I when both filaments were printed with part cooling off the Bambu pa6cf had far better layer adhesion. I’ve also noticed print quality on the pa6 wasn’t any worse than the ppa. When you tested the Sirya ppa was the fan off? If so the table is far less useful to compare materials. Maybe you could make a “zero part cooling layer adhesion” portion of the table (if the filament is capable of printing with ok quality) to get a better like for like comparison.

2025-03-08 05:26:30 +0000 UTCJust ordered the PPA-CF core after watching your video - I look forward to trying it out!

2025-03-08 01:50:28 +0000 UTCGreat video mate! I rolled the dice on the cf core stuff after you hinted at it a video ago. It prints really nicely, seems easier to work with than the bbl ppa-cf and is cheaper. I'm sold!

2025-03-07 22:46:11 +0000 UTCAnother great video that shows why real world testing trumps everything else. Makes the patreon all so very worth it.
Jim McPherson
2025-03-07 22:31:17 +0000 UTCWOW, the PPA-CF is impressive. I'm a bit shocked that the temperature resistance was so much higher than non-CF PPA. Any ideas why the CF was more than 2X higher? Did the CF make it self-anneal or something while printing? :)
