Bambu Lab PAHT CF Black Summary

This filament is tricky to print, strong and heat-resistant. Worth watching: it can be moisture-sensitive and a bit smelly to print.

Print characteristics

Shrinkage 0.5-1.5 %

Strengths

Strong parts that hold up under load
Handles heat well

Things to watch

Soaks up moisture quickly, keep it sealed and dry before printing
Gives off noticeable fumes, print with ventilation or filtration
Shrinks as it cools, which can affect dimensional accuracy
Fussy about bed adhesion, use a brim, glue, or a textured plate

Drying

This material is very hygroscopic, it pulls moisture from the air quickly. When it needs drying, run it at 80-100 °C for 8-12 h. Keep it in a heated dry box while printing for the cleanest results.

Specialties

Water Resistant / HydrophobicResists absorbing water or moisture from the air. Maintains mechanical properties in humid or wet environments. For marine parts, outdoor components, or wet environment applications.

High TemperatureWithstands extreme heat (150°C+) for industrial, aerospace, and engine-adjacent applications. Requires specialized high-temp printers (300°C+ hotend, enclosure).

High StrengthResists bending or pulling apart under heavy load. Very stiff.

Wear ResistantResists surface wear from friction and sliding. Good for gears, bushings, conveyor parts, or any component that rubs against other surfaces.

Chemical ResistantResists damage from oils, fuels, acids, industrial chemicals or solvents. For laboratory equipment, fuel system components, or chemical storage.

Low ShrinkagePart holds its exact shape over time. No warping, sagging, or unexpected size changes. Essential for precision parts, press-fits, and mechanisms under constant load.

Fatigue ResistantWithstands repeated bending without cracking. For living hinges, snap-fits, and moving parts.

UV ResistantResists degradation from sunlight exposure (UV radiation) and outdoor weather conditions. For outdoor signage, garden equipment, automotive exterior parts, or marine components.
