$150 for 0.75kg versus $56/kg from others. Gram for gram, that’s nearly 4x as expensive! Am I overlooking something? Is there something special about it? What, if anything, makes it worth the price?

Yeah no clue why. I bought 1kg of Creality PPA-CF for $75
If you insist on bambu brand, wait for a sale like I did or buy it from aliexpress:
I love Sarayatech filaments but I bet thats just paht-cf. Bambu sells it for $50 for .5 kilo. So, double lol

Yeah, I hate the ambiguity of that listing. OK, how about this then?
Surely that would be PPA-CF, not PAHT-CF, right? So, that would put the Bambulab price at 2.32x as much, gram for gram, as compared to Syratech’s premium core version.
Are you outside the US? For some reason your aliexpress links never resolve for me. I always get:
and even weirder, when I do my own search on aliexpress for ppa-cf, it only shows me creality ppa-cf, no bambulab. Strange, isn’t it?
Ya im in Canada. Siraya PAHT is PPA. They used to call it PAHT (Nylon High Temp) before bambu came out with PPA, they renamed it after. You can check the TDS and its PPA based.

Well, as long as we’re on the topic, does PPA-CF print as nicely as PPS-CF does? For the most part, my PPS-CF prints have come out pristine. The only challenges I’ve encountered have been brittleness of the filament and a possible (intermittent?) firmware bug related to not heating the nozzle to a high enough temperature when loading PPS-CF. If PPA-CF prints as nicely and without the brittleness problem and without the firmware bug, that would be awesome.
If it’s made with Polyphthalamide it’s ppa, if it’s made with polyamide it’s pa or paht depending on which polyamide they use.
The siraya tech stuff is made with Polyphthalamide, so it is a true PPA. It’s very good stuff btw. No warping and really stiff, unlike pa-cf
Edit: just read your last comment. It is brittle, so don’t bent it too far. Maybe a little less brittle than pps-cf.

150 (with shipping) CAD vs 191 in the store was it cheaper before?

I havent ventured in the these high temp filaments yet as I havent needed to justify the prices yet, but can someone tell me which one is easiest to print with the lowest VOCs (and maybe the least hygroscope cuz humidity is getting up there currently. I was gonna grab that PAHT-CF when bambu did that one day sale thing, but I forgot and missed it lol.
It’s my understanding that all PPA-CF is a form of PAHT-CF, but not all PAHT-CF is PPA-CF. PAHT is basically a description for High Temperature Nylon.
I believe the only one where the main fume given off durning printing is not carcinogenic is nylon. Caprolactam is what it gives off.
PET-CF is a decent engineering material that doesn’t have all the nasty fumes like abs/asa/nylon/PC. Assume it’s still not healthy to breath, but it’s not exposing you to styrene, caprolactam, or BPA like the others will.
They’re all hygroscopic and need to be dry to print properly.
Cool, yeah i figured they all were I was just trying to figure out which one would give me the longest period of time before it was need a redry. My printer is also in my basement and i only have one small window (one of those block windows with the tiny vent slates) so as i’m assuming no of them are safe, i was hoping one was more manageable then say ASA. I can’t even print that in the same area without getting a headache from the smell
PET-CF prints really smooth and nice. At least the Polymaker one I used does. However the parts were pretty weak and split(not on layer lines) where I had bolts going through with no friction(bolts with nuts on the other side) once the screws were only finger tight. PET-CF is the only filament I HAVE to anneal to get good strength and then it is really strong. Others have mentioned the same issue.

Yea, don’t be printing ASA or ABS without ventilation. Lookup what styrene is and how it affects you. It’s nasty stuff.
I would personally switch to pet if you can’t get a solid ventilation setup. Nylon should be vented as well, but at least it’s not carcinogenic and can be filtered if needed.
As @MotoGP11991 said, it definitely benefits from annealing.
In a moist basement, you’re not going to get more than a day or 2 without needing to dry again. Your best bet is to dry what you have and store it in air tight containers with desiccant. Bags leak, so I wouldn’t even consider those. 4L cereal containers work well.
PAHT CF is “generally” a PA12 CF (with lower water absorption and normally weaker than PA6). PPA is more of a general term, “Performance” PolyAmide. Its not wrong to assume many PAHTs will also be PPAs, but its a slippery slope that doesn’t appear to be define cleanly. I think there are PPAs that are based on PA6s or PA11s (or some mix of any of the 3).
Crazy marketing going on in this space.
That was just the introductory pricing.
Thanks, I was thinking of PAHT CF, not PPA CF.
PPA is an acronym for Polyphthalamide, which is a specific type of Nylon.
It’s just confusing when they sell PAHT-CF filament, but the underlying nylon type used isn’t always made readily available. Sometimes you have to dig a bit to see what the manufacturer is calling PAHT-CF.
