PPA-CF Print Settings
Expert-recommended PPA-CF (High Performance) settings for all Bambu Lab printers
Why use PPA-CF?
- Ultra-high heat resistance (HDT up to 200°C)
- Superior to PA6-CF and PAHT-CF for extreme temperature applications
- Excellent chemical resistance for harsh industrial environments
- Professional-grade material for aerospace and automotive
- Carbon fiber reinforcement for maximum stiffness-to-weight ratio
- Maintains mechanical properties at elevated temperatures
What are the best PPA-CF print settings?
Use default Bambu Lab temperature profiles for PPA-CF. Recommended outer wall speed is 100 mm/s.
| Setting | Value | Note |
|---|---|---|
| quality.lineWidth.default | 0.46 | Wider lines for high-temp CF flow |
| strength.walls.wallLoops | 4 | Maximum walls for extreme applications |
| strength.infill.density | 30 | High infill for structural integrity |
| strength.infill.pattern | Gyroid | Isotropic strength for demanding applications |
| speed.layers.outerWall | 100 | Slow for high-performance surface quality |
| support.filament.interface | Support for PA/PET (Bambu Lab) | PA/PET interface for high-temp PPA-CF |
| support.filament.base | Same as model | PPA-CF as bulk support |
| speed.layers.innerWall | 180 | Moderate speed for PPA-CF |
| speed.layers.sparseInfill | 250 | Slow infill for viscous high-temp CF |
| speed.initial.layer | 20 | Very slow first layer |
| others.bed.brimType | Outer and inner brim | Maximum adhesion for warping prevention |
| others.bed.brimWidth | 12 | Extra-wide brim |
| support.thresholdAngle | 25 | Conservative support threshold |
What nozzle size should I use for PPA-CF?
0.4mm hardened steel — extremely abrasive
0.4mm hardened steel nozzle
0.6mm hardened steel
How do I dry PPA-CF filament?
Dry PPA-CF at 80°C for 12+ hours. Critical — must be bone-dry for high-temp printing
What support material should I use with PPA-CF?
Recommended: PPA-CF base + Support for PA/PET interface
Base: Same as model (PPA-CF) | Interface: Support for PA/PET (Bambu Lab)
PPA-CF as bulk support with PA/PET at interface. Complex geometries may still need design modifications to reduce support needs.
~25% less support filament used
Expert Tips for PPA-CF
- The most demanding material Bambu offers — requires perfect drying (80°C, 12h+).
- H2D with hardened nozzle only. No other Bambu printer can handle PPA-CF temperatures.
- Print in a well-ventilated area — high-temp nylon fumes can be irritating.
- Cost is $149.99/spool — plan prints carefully to minimize waste.
Which Bambu Lab printers work with PPA-CF?
Use with caution on: X1, H2S, H2C, P1S, P2S, A1, Ender 3 V3 KE, Ender 3 S1 Pro, J1, Artisan
Alternatives to PPA-CF
If you can accept ~170°C HDT instead of ~200°C at significantly lower cost
Trade-offs: Lower maximum service temperature. Slightly lower chemical resistance
If your budget is limited and you need a good nylon-CF at the lowest price point
Trade-offs: Significantly lower heat resistance. Lower overall performance
