PA6-CF Print Settings
Expert-recommended PA6-CF (Nylon) settings for all Bambu Lab printers
Why use PA6-CF?
- Carbon fiber reinforced Nylon 6 for excellent stiffness
- Good chemical resistance for industrial environments
- Better layer adhesion than PAHT-CF in some applications
- Excellent for jigs, fixtures, and functional prototypes
- Lower printing temperature than PAHT-CF while retaining CF benefits
- Professional matte finish from carbon fiber texture
What are the best PA6-CF print settings?
Use default Bambu Lab temperature profiles for PA6-CF. Recommended outer wall speed is 130 mm/s.
| Setting | Value | Note |
|---|---|---|
| quality.lineWidth.default | 0.44 | Wider lines for CF flow |
| strength.walls.wallLoops | 3 | Extra walls for CF strength |
| strength.infill.density | 20 | Higher infill for nylon parts |
| strength.infill.pattern | Gyroid | Isotropic strength pattern |
| speed.layers.outerWall | 130 | Slower for PA6-CF surface quality |
| support.filament.interface | Support for PA/PET (Bambu Lab) | Dedicated PA/PET interface for nylon |
| support.filament.base | Same as model | PA6-CF as bulk support |
| speed.layers.innerWall | 220 | Moderate CF speed |
| speed.layers.sparseInfill | 350 | Reduced for CF viscosity |
| speed.initial.layer | 30 | Slow first layer for nylon adhesion |
| others.bed.brimType | Outer and inner brim | Nylon warping prevention |
| others.bed.brimWidth | 8 | Wide brim for nylon |
| support.thresholdAngle | 28 | Lower threshold for nylon droop |
What nozzle size should I use for PA6-CF?
0.4mm hardened steel REQUIRED
0.4mm hardened steel nozzle
0.6mm hardened steel
How do I dry PA6-CF filament?
Dry PA6-CF at 80°C for 8-12 hours. Critical — nylon absorbs moisture within hours
What support material should I use with PA6-CF?
Recommended: PA6-CF base + Support for PA/PET interface
Base: Same as model (PA6-CF) | Interface: Support for PA/PET (Bambu Lab)
PA6-CF as bulk support with PA/PET at interface. Saves expensive support filament while ensuring clean separation at model contact points.
~25% less support filament used
Expert Tips for PA6-CF
- Dry at 80°C for 8+ hours. Nylon is the most moisture-sensitive common filament.
- Enclosed printer mandatory — A1 is not suitable for nylon materials.
- Hardened nozzle required for all CF-reinforced materials.
- PA6-CF is easier to print than PAHT-CF while offering 80% of the performance.
Which Bambu Lab printers work with PA6-CF?
Use with caution on: P1P, A1, Ender 3 V3 SE
Alternatives to PA6-CF
If you want CF stiffness with dramatically easier printing (no enclosure, no drying)
Trade-offs: Much lower heat resistance (~55°C vs ~160°C). No chemical resistance. More brittle
If you need a middle-ground CF option that doesn't require an enclosure
Trade-offs: Lower stiffness than PA6-CF. Lower heat resistance
