PA6-GF Print Settings
Expert-recommended PA6-GF (Nylon) settings for all Bambu Lab printers
Why use PA6-GF?
- Glass fiber reinforced nylon for excellent stiffness at lower cost than CF
- Better impact resistance than CF-reinforced variants
- Good heat resistance for functional applications
- Less abrasive on nozzles than carbon fiber (but still needs hardened nozzle)
- Excellent for larger structural parts where CF cost is prohibitive
What are the best PA6-GF print settings?
Use default Bambu Lab temperature profiles for PA6-GF. Recommended outer wall speed is 140 mm/s.
| Setting | Value | Note |
|---|---|---|
| quality.lineWidth.default | 0.44 | Wider for GF flow |
| strength.walls.wallLoops | 3 | Extra walls for fiber-reinforced strength |
| speed.layers.outerWall | 140 | Moderate speed for GF |
| speed.layers.innerWall | 230 | Moderate inner wall speed |
| speed.layers.sparseInfill | 350 | Reduced for GF viscosity |
| support.filament.interface | Support for PA/PET (Bambu Lab) | PA/PET interface for glass fiber nylon |
| support.filament.base | Same as model | PA6-GF as bulk support |
| speed.initial.layer | 30 | Slow first layer |
| others.bed.brimType | Outer and inner brim | Nylon warping prevention |
| others.bed.brimWidth | 8 | Wide brim |
What nozzle size should I use for PA6-GF?
0.4mm hardened steel — GF is abrasive though less than CF
0.4mm hardened steel nozzle
0.6mm hardened steel for fast prints
How do I dry PA6-GF filament?
Dry PA6-GF at 80°C for 8-12 hours. Critical — nylon absorbs moisture within hours
What support material should I use with PA6-GF?
Recommended: PA6-GF base + Support for PA/PET interface
Base: Same as model (PA6-GF) | Interface: Support for PA/PET (Bambu Lab)
PA6-GF as bulk support with PA/PET at interface only. Glass fiber texture aids base support removal.
~25% less support filament used
Expert Tips for PA6-GF
- PA6-GF is less abrasive than CF variants but still requires a hardened nozzle.
- Glass fiber gives better impact resistance than carbon fiber at the cost of some stiffness.
- Dry thoroughly before printing — all nylon materials are moisture-sensitive.
Which Bambu Lab printers work with PA6-GF?
Alternatives to PA6-GF
If you want a glass fiber option at lower cost with easier availability
Trade-offs: Lower heat resistance than PA6-GF. Still requires enclosure
If you need maximum stiffness and can sacrifice some impact resistance
Trade-offs: Carbon fiber is stiffer but more brittle than glass fiber. Slightly higher cost
