Siraya tech PPA-CF
300°c nozzle temp
0.4mm High Flow hot ends
I bought 0.6mm hot ends thinking I’d need them for filaments like this, we don’t lol. The 0.4mm hot ends work great. I thought it was a little risky with the HF hot ends considering HF nozzles are usually clog prone with filled filaments.
I foresee these 0.6mm hot ends being strictly reserved for soft tpu.
Printing KYZ designs H2D aux fan to air scrubber conversion. It’ll be done tomorrow sometime.
I print all my nylons and CF filaments with 0.4mm HF nozzles, never once had a clog on my X1/P1 and now H2D. I think they recommend the 0.6mm just to be on the safe side, although it is supposed to increase part strength a tiny bit due to the wider extrusions.
Yea, I guess I believed too much of the internet hype without just actually seeing for myself.
Could always just increase the line width of the walls for better strength. I already run my infill at 0.6mm.
Yes i do that as well sometimes on functional parts, 0.5-0.6mm extrusion width except on outer wall to keep them looking good.
I thought PA6-GF would be overkill for this application. I see you are talking precautions though - that’s a big brim, and gyroid too.
Siraya tech PPA-CF - that is so much cheaper than the Bambu one - and you even get a full kilo. What do you think so far?
Should be good as Siraya filament is good quality. I stocked up on some bambu PPA when they had a sale on it when they first released it but i did see the bambu PPA on aliexpress for pretty cheap, even after the expensive shipping.
How much was it on sale for? This doesn’t even make sense to buy with gift cards with such a big difference to the Siraya stuff. (I haven’t compared mechanical properties or anything though)
Its all the same stuff chemically might even be made at the same filament factory, so I would just buy whatever is the cheapest.
I think is was on sale for $90 when they first released it, so i grabbed 2 rolls, had some gift cards to burn.
Yea, I didn’t fully trust it to not warp, but so far there is zero warping at all. This is my first go about with ppa-cf so I wasn’t sure what to expect. 10mm brim to keep things planted and gyroid to use a less linear infill so it didn’t contribute to warping.
Much much cheaper than the Bambu stuff haha. So far it seems to print much better than the eSun pa-cf I was printing yesterday. That eSun warps as soon as you look at it wrong hahah. I’ve printed a lot of siraya tech pet-cf so I fully expected their ppa-cf to give me a good experience.
The esun PA-CF is the worst. It turns to rubber in like 2 days after printing and is useless!
