Print Quality Profiles
Three presets for common use cases with ABS-CF on the Anycubic Kobra 3 Combo.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 50 mm/s | 10-15% | Rapid prototyping, test fits |
| Standard | 0.20mm | 40 mm/s | 15-20% | General purpose, everyday prints |
| Quality | 0.12mm | 30 mm/s | 20-30% | Miniatures, display pieces, fine detail |
Bed Adhesion
ABS-CF uses the same adhesion methods as standard ABS. Use a PEI sheet at 90-110°C with ABS slurry or glue stick. A brim is strongly recommended. The carbon fibers reduce warping compared to plain ABS, but an enclosure is still essential.
Temperature Tuning Guide
Nozzle: 250°C
Range: 240-260°C. Printer max: 300°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 100°C
Range: 90-110°C. Printer max: 110°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
Troubleshooting ABS-CF on Anycubic Kobra 3 Combo
Pro Tips for ABS-CF
A hardened steel nozzle (0.5mm+) is mandatory for carbon fiber filaments
An enclosure is non-negotiable -- ABS-CF warps like ABS but the fibers help with dimensional stability
Dry filament at 77°C for 6+ hours before printing; moisture causes bubbling and weak layers
ABS-CF produces less warping than plain ABS due to the carbon fibers reducing shrinkage
For outdoor applications, consider ASA-based composites instead -- ABS-CF yellows in sunlight
Support Settings
For prints requiring supports with ABS-CF, use tree supports for easier removal and less scarring. Set a 0.15-0.2mm Z-distance between support and model. If you have a dual-extruder setup, consider PVA (for PLA/PETG) or HIPS (for ABS) as dedicated water/solvent-soluble support material.

ABS-CF at a Glance
Strengths
- Much stiffer than standard ABS with less warping
- Good heat resistance (similar to ABS, HDT ~100C)
- Professional matte black finish
- Better dimensional accuracy than plain ABS
- Ideal for functional parts needing rigidity and heat resistance
Weaknesses
- Requires hardened steel nozzle (carbon fibers destroy brass)
- Enclosure required (emits fumes like ABS)
- More brittle than standard ABS (reduced impact resistance)
- Use 0.5mm+ nozzle to avoid clogging from fibers
- Poor UV resistance (same as ABS, consider ASA-CF for outdoor use)
