ASA-CF Print Settings
Expert-recommended ASA-CF (ASA) settings for all Bambu Lab printers
Why use ASA-CF?
- Carbon fiber reinforced ASA for maximum outdoor structural rigidity
- UV-resistant AND stiff — ideal for drone frames, automotive parts
- Professional matte finish from carbon fibers
- Better dimensional stability than standard ASA
- Excellent strength-to-weight ratio for outdoor applications
What are the best ASA-CF print settings?
Use default Bambu Lab temperature profiles for ASA-CF. Recommended outer wall speed is 130 mm/s.
| Setting | Value | Note |
|---|---|---|
| quality.lineWidth.default | 0.44 | Wider for CF fiber flow |
| strength.walls.wallLoops | 3 | More walls for CF strength |
| speed.layers.outerWall | 130 | Slow for CF surface quality |
| speed.layers.innerWall | 200 | Moderate CF speed |
| speed.layers.sparseInfill | 350 | CF viscosity requires slower infill |
| support.filament.interface | HIPS | Dissolvable interface for ASA-CF |
| support.filament.base | Same as model | ASA-CF as bulk support |
| speed.initial.layer | 35 | Slow first layer |
| others.bed.brimType | Outer and inner brim | Brim for ASA-CF warping prevention |
| others.bed.brimWidth | 6 | Medium brim width |
What nozzle size should I use for ASA-CF?
fine — 0.4mm
0.4mm hardened steel REQUIRED
medium — 0.4mm
0.4mm hardened steel nozzle
coarse — 0.6mm
0.6mm hardened steel
How do I dry ASA-CF filament?
Dry ASA-CF at 70°C for 4-6 hours. Moderate moisture absorption — CF fibers increase sensitivity
What support material should I use with ASA-CF?
Recommended: ASA-CF base + HIPS interface
Base: Same as model (ASA-CF) | Interface: HIPS (dissolvable in limonene)
ASA-CF as bulk support with HIPS at interface. CF texture helps base supports break away; HIPS interface dissolves cleanly.
~30% less HIPS filament used
Expert Tips for ASA-CF
- Hardened steel nozzle is mandatory — carbon fibers are extremely abrasive.
- Enclosure strongly recommended for ASA-CF.
- The combination of UV resistance + CF stiffness makes this ideal for outdoor structural parts.
