Annealing of PLA-CF early access
Added 2025-02-19 11:04:46 +0000 UTCHello everyone,
I barely managed to finish my latest video—watch it here: https://youtu.be/5XOqUfmWhig (public on Friday). Unfortunately, I’ve had the flu for over a week now and have almost completely lost my voice. That’s why my voice will sound weird in the next few videos (including this one). I tried AI voice cloning, but it sounded too different, so you’ll hear my sick voice instead.
In the meantime, I’ve been working on projects that don’t require talking, like 3D printing and testing. I found the Siraya PPA-CF Core filament very interesting—it has a nylon exterior with a 25% carbon fiber core. The flow remains laminar, meaning the core stays inside (I confirmed this under a microscope). This design protects the nozzle (and our hands! 😅) and improves layer adhesion. That video should be ready in about 10 days.
I’m also testing a few other materials:
Tinmorry PETG-GF (glass fiber)
BambuLab PC-FR
Sunlu PC-ABS
And soon, I’ll be reviewing the Qidi PLUS4 along with all three PPS-CF filaments.
Now, a question for you: Sunlu PC-ABS officially requires a 90-100°C chamber temperature, but I’ve found that the Qidi PLUS4 can print it. The BambuLab X1C can as well, with some simple hacks—like preheating the bed and waiting at least half an hour.
Which printer would you like me to test it on: Qidi PLUS4 or BambuLab X1C?
Comments
On a K1 Max, I could reach 70 °C with a blanket and a bed temperature of 120 °C, so it should also be possible with a X1C. Now I have a Qidi Q1 Pro with mods for 65 °C chamber heating, therefore I would still prefer the Qidi PLUS4.
