In this video, I test BIQU CarbonCore25 filament in four different base materials: PLA, PETG, ABS, and PA.
The goal is to see how the same carbon-core concept behaves when the surrounding polymer changes — from printability and brittleness to mechanical performance.
All filaments were printed using the same test methodology I use across my channel, so the results are directly comparable to many earlier filament tests.
