热床附着
PHA(聚羟基烷酸酯)与 PLA 类似粘合。在 50-60°C 使用干净的 PEI 片或玻璃热床配胶棒。PHA 是生物可降解的,比 PLA 略微更柔性。
温度调校指南
Nozzle: 188°C
Range: 175-200°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: 50°C
Range: 40-60°C. Printer max: 90°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
在 Anycubic Kobra 2 Plus 上打印 PHA 的问题排查
PHA 使用技巧
PHA 完全生物可降解和可堆肥 -- PLA 的更绿色替代品
打印设置与 PLA 非常相似;从 PLA 设置开始并从那里调整
PHA 比 PLA 略微更柔性,冲击时脆性更少
储存在凉爽、干燥的地方;PHA 在湿度环境中生物降解更快
支撑设置
For prints requiring supports with PHA, 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.
