Qidi PPS-CF is marketed as a high-performance carbon fiber filament with outstanding heat resistance and strength — but does it live up to that promise? In this video, I put it through my complete testing process: from slicing and printing to mechanical and thermal stress tests.

While it can handle extreme temperatures, getting good layer adhesion is not as simple as it seems. One small change in your print settings, and your part might look strong… but break apart under load.
Join me as I unbox the filament, explore its printing behavior, and reveal how it performs in real-world mechanical tests. Is it worth the hassle?
