PPS-CF Print Settings
Expert-recommended PPS-CF (High Performance) settings for all Bambu Lab printers
Why use PPS-CF?
- Highest continuous service temperature of any Bambu filament (~220°C)
- Exceptional chemical resistance — resistant to almost all solvents
- Self-extinguishing flame resistance (UL94 V-0)
- Aerospace and medical-grade material quality
- Carbon fiber reinforcement for extreme stiffness
- Near-metal replacement capability for specialized applications
What are the best PPS-CF print settings?
Use default Bambu Lab temperature profiles for PPS-CF. Recommended outer wall speed is 80 mm/s.
| Setting | Value | Note |
|---|---|---|
| quality.lineWidth.default | 0.46 | Wider lines for extreme-temp CF flow |
| strength.walls.wallLoops | 4 | Maximum walls for aerospace-grade parts |
| strength.infill.density | 30 | High infill for structural applications |
| strength.infill.pattern | Gyroid | Isotropic strength |
| speed.layers.outerWall | 80 | Very slow for high-temp material |
| support.filament.interface | Support for PA/PET (Bambu Lab) | Verify compatibility at PPS-CF temps |
| support.filament.base | Same as model | PPS-CF as bulk support |
| speed.layers.innerWall | 150 | Slow inner walls |
| speed.layers.sparseInfill | 200 | Very slow infill for PPS-CF |
| speed.initial.layer | 20 | Extremely slow first layer |
| others.bed.brimType | Outer and inner brim | Maximum adhesion |
| others.bed.brimWidth | 12 | Maximum brim width |
| support.thresholdAngle | 20 | Very conservative support threshold |
What nozzle size should I use for PPS-CF?
0.4mm hardened steel — PPS-CF is very abrasive
0.4mm hardened steel nozzle — H2D required
0.6mm hardened steel for practical PPS-CF prints
How do I dry PPS-CF filament?
Dry PPS-CF at 80°C for 12+ hours. Critical — must be bone-dry for extreme-temp printing
What support material should I use with PPS-CF?
Recommended: PPS-CF base + Support for PA/PET interface
Base: Same as model (PPS-CF) | Interface: Support for PA/PET (Bambu Lab)
Limited support options at PPS-CF temperatures. Interface-only approach conserves expensive support filament. Design parts to minimize support needs.
~25% less support filament used
Expert Tips for PPS-CF
- PPS-CF is the most extreme material Bambu offers — treat it with respect.
- Requires H2D at maximum nozzle temperature (~350°C). No other printer can handle it.
- Extremely thorough drying required — 80°C for 12+ hours.
- At $129.99/spool, plan and prototype with cheaper materials first.
- Chemical resistance is unmatched — resists almost every solvent and acid.
Which Bambu Lab printers work with PPS-CF?
Use with caution on: X1, H2D, H2S, H2C, P1S, P2S, A1, Ender 3 V3 KE, Ender 3 S1 Pro, J1, Artisan
Alternatives to PPS-CF
If you need extreme performance but PPS-CF is overkill for your application
Trade-offs: Lower chemical resistance than PPS-CF. Lower max service temperature (~200°C vs ~220°C)
If you want to start with a more accessible high-performance nylon before committing to PPS
Trade-offs: Significantly lower heat and chemical resistance. Not flame-retardant
