PPA is the strongest filament type I’ve ever tested, and in this video, I’m pushing it to the limit! What makes this test unique is that Siraya Tech offers PPA in three different variants:
✅ Regular PPA – A high-performance polymer with excellent strength and durability.
✅ PPA-CF – Reinforced with carbon fibers for added stiffness and strength.
✅ PPA-CF Core – A unique version where carbon fibers are concentrated in the center of the filament, optimizing mechanical properties.

These filaments come at an affordable price compared to other high-performance materials, but how do they perform in real-world tests? I’ll go through print settings, annealing effects, mechanical testing, and more to see how they stack up.
