Testing BambuLab PAHT-CF: A PA12-Based Carbon Fiber Filament

In this video, I’m testing BambuLab’s PAHT-CF filament, which is a high-temperature nylon reinforced with carbon fiber and based on PA12. I go through its specifications, print settings, how it behaves during printing, and then run a full set of mechanical tests—including tensile, shear, torsion, impact, bending, creep, and heat resistance.

Let’s find out! 👉 Patreon supporters get early access to videos like this, and a downloadable summary spreadsheet with all test results for easier comparison across different materials.
