Siraya Tec PPA-CF - fine-tuning
Hello everyone.
I only came into contact with PPA-CF when I got my Bambu Lab X1C, and I was immediately impressed by this type of filament.
Most recently, I used Creality PPA-CF, but I wasn't convinced by the print quality.
Now I've discovered Siraya Tec PPA-CF here in the forum and have printed it according to the manufacturer's specifications.
I think I'll create a profile with a maximum of 10% cooling. Even though I only printed at 305 degrees at the nozzle and 100 degrees bed temperature, I think the filament was too hot in some places.
Tomorrow I'll take pictures to compare.

Classic Benchy smokestack issue you see with all "hot" filaments. For ascetic reasons you can insert this at the start of the smoke stack layer:
M220 S50 ; Set print speed to 50% M106 S102 ; Set fan to 40% (255 * 0.40 = 102)

Thank you. I'll test it out 🙂

There is a high chance that if you print two Benchies together the problem will go away as the hot-end will move to the other one for long enough at each layer to allow cooling to complete.
Cheerio,

I only took 15%, which was enough. This time at 310 degrees. I'm still loading 3MF files.

Can't wait to print this, been sitting in my amazon cart for weeks.

Just make sure you dry it at 80C+ (100 is better) for 12 or more hours before you print it.

Thanks, my sunlu only goes to 70, waiting for my West3D Filament Toaster to ship.

Hello, everyone.
The first real test with Siraya Tec PPA-CF was a two-hour print at 310°C to integrate the heat shield into the fan shroud.
The results, including the overhangs, are quite impressive.

My advice would be to anneal the part. I've noticed some part creep on unannealed PPA that essentially results in me having to periodically retighten screws. If I remember, Stefan at CNC Kitchen did a video on this awhile back.

That's what I plan to do with the hook from CNC Kitchen. I've already printed one that I didn't post-anneal, and I'm going to post-anneal the other one.
@Hyiger: What settings did you use? Online, you can find values ranging from 80 to 100 degrees and 4 to 8 hours. Does that mean 100 degrees for 4 hours and 80 degrees for 8 hours?

100 for 4 hrs. I'm using my solder reflow over for this.
