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.

Skill level Advanced

Advanced. Wants careful tuning, strong bed adhesion, and usually an enclosure.

Print characteristics

Layer adhesion ExceptionalBed adhesion Requires Special PrepBridging & overhang GoodSpeed sensitivity ModerateWarping ModerateShrinkage 0.5-1.5 %Stringing LowOozing LowOdor Moderate

Strengths

Strong parts that hold up under load
Handles heat well
Resists oils, solvents, and chemicals
Layers bond strongly for clean, watertight prints
Prints clean with minimal stringing

Things to watch

Can warp on large or sharp-cornered prints
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

Color & finish

A solid Black filament. It reads as a near-black, close to midnight blue.

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.
