打印质量预设
Three presets for common use cases with PETG-CF on the Creality Ender 3 Pro.
| Profile | Layer Height | Speed | Infill | Best For |
|---|---|---|---|---|
| Draft | 0.28mm | 50 mm/s | 10-15% | Rapid prototyping, test fits |

| Quality | 0.12mm | 30 mm/s | 20-30% | Miniatures, display pieces, fine detail |
热床附着
PETG-CF 与标准 PETG 粘合类似。在光滑 PEI 上使用有纹理的 PEI 片或涂胶棒作为脱模剂。碳纤维与普通 PETG 相比减少翘曲,因此粘合通常更容易。移除打印件前让热床完全冷却。
温度调校指南
Nozzle: 245°C
Range: 230-260°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: 75°C
Range: 70-80°C. Printer max: 110°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting

PETG-CF 使用技巧
硬化钢喷嘴是强制的 -- 从不用黄铜做碳纤维耗材
使用 0.5mm 或 0.6mm 喷嘴以获得最佳可靠性和流量
每次使用前干燥 PETG-CF -- 水分导致起泡和削弱碳纤维粘合
比普通 PETG 慢 30-40% 打印以获得最佳表面质量和纤维排列
PETG-CF 在需要刚性而无尼龙-CF 高温的功能零件上表现出色
支撑设置
For prints requiring supports with PETG-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.
