热床附着
PC-ABS 需要外罩和高热床温度(100-110°C)。使用 PEI 片配胶棒或 ABS/PC 浆液。裙边对大型零件至关重要。粘合方法与 ABS 类似但翘曲倾向中等。
温度调校指南
Nozzle: 265°C
Range: 250-280°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: 100-115°C. Printer max: 100°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting

PC-ABS 使用技巧
外罩至关重要 -- PC-ABS 翘曲比纯 PC 更少,但比纯 ABS 更多
在 250-270°C 喷嘴和 100-110°C 热床打印以获得最佳效果
PC-ABS 结合 PC 的抗冲击性与 ABS 的可打印性 -- 功能零件的好选择
通风很重要 -- PC-ABS 在打印时释放烟气
支撑设置
For prints requiring supports with PC-ABS, 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.
