Bambu Lab PPA CF Black Summary

This filament is demanding to print, strong and heat-resistant. Worth watching: it can be prone to warping and moisture-sensitive.

Skill level Expert

Expert. Best suited to experienced makers: enclosure, precise temps, and patience.

Print characteristics

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

Strengths

Strong parts that hold up under load
Stiff and rigid, resists flexing
Excellent heat resistance for hot environments
Resists oils, solvents, and chemicals
Layers bond strongly for clean, watertight prints
Prints clean with minimal stringing

Things to watch

Prone to warping, use a heated bed and ideally an enclosure
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
Can be brittle, may crack under sharp impact
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

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

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.

Heat ResistantWithstands elevated temperatures (hot car, warm electronics) without deforming. Printable on standard printers. HDT ~80-120°C.

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

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.

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

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

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.
