Print Quality Profiles
Three presets for common use cases with Carbon Fiber PLA on the Anycubic Kobra 2 Neo.
| 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
Carbon Fiber PLA adheres similarly to regular PLA. A clean PEI sheet works well. For glass beds, use glue stick. The carbon fibers reduce warping compared to regular PLA.
Temperature Tuning Guide
Nozzle: 215°C
Range: 200-230°C. Printer max: 260°C.
- Poor layer adhesion? Increase +5°C
- Stringing or oozing? Decrease -5°C
- Print a temperature tower to find your exact sweet spot
Bed: 58°C
Range: 50-65°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 Carbon Fiber PLA on Anycubic Kobra 2 Neo
Pro Tips for Carbon Fiber PLA
A hardened steel nozzle is mandatory -- do not print CF PLA with a brass nozzle
Use a 0.5mm or 0.6mm nozzle for the most reliable printing with carbon fibers
Print 25-50% slower than regular PLA to reduce stress on the extruder and improve quality
CF PLA excels in stiffness and rigidity -- ideal for structural parts, not impact-resistant ones
The matte finish looks professional and hides layer lines better than glossy filaments
Support Settings
For prints requiring supports with Carbon Fiber PLA, 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.
