ABS-GF Print Settings
Expert-recommended ABS-GF (ABS) settings for all Bambu Lab printers
Why use ABS-GF?
- Glass fiber reinforced ABS for improved stiffness and heat resistance
- Lower cost than CF-reinforced engineering materials
- Better dimensional stability than standard ABS
- Reduced warping compared to standard ABS
- Good for jigs, fixtures, and functional prototypes
- Can still be acetone-smoothed for finish
What are the best ABS-GF print settings?
Use default Bambu Lab temperature profiles for ABS-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 GF strength |
| speed.layers.outerWall | 140 | Moderate speed for ABS-GF |
| speed.layers.innerWall | 230 | Moderate inner wall speed |
| speed.layers.sparseInfill | 350 | Reduced for GF viscosity |
| support.filament.interface | HIPS | Dissolvable interface for ABS-GF |
| support.filament.base | Same as model | ABS-GF as bulk support |
| speed.initial.layer | 30 | Slow first layer |
| others.bed.brimType | Outer and inner brim | ABS warping prevention |
| others.bed.brimWidth | 8 | Wide brim |
What nozzle size should I use for ABS-GF?
0.4mm hardened steel — GF is abrasive
0.4mm hardened steel nozzle
0.6mm hardened steel for fast prints
How do I dry ABS-GF filament?
Dry ABS-GF at 70°C for 4-6 hours. Moderate moisture absorption — GF variant
What support material should I use with ABS-GF?
Recommended: ABS-GF base + HIPS interface
Base: Same as model (ABS-GF) | Interface: HIPS (dissolvable in limonene)
ABS-GF as bulk support with HIPS at interface only. GF texture helps base break away; HIPS dissolves for clean model separation.
~30% less HIPS filament used
Expert Tips for ABS-GF
- Enclosure mandatory for ABS-GF — same warping concerns as standard ABS.
- Hardened nozzle recommended even for glass fiber reinforcement.
- ABS-GF warps less than standard ABS due to fiber reinforcement.
Which Bambu Lab printers work with ABS-GF?
Alternatives to ABS-GF
If you want fiber-reinforced parts without needing an enclosure
Trade-offs: Carbon fiber instead of glass fiber — stiffer but more brittle. Different surface finish
If you need higher stiffness and heat resistance from the nylon GF family
Trade-offs: Higher cost. Requires thorough drying. Harder to print
