热床附着
PVA 用作支撑材料,应粘合到主要材料使用的任何热床表面。使用 50-60°C 的热床温度。
温度调校指南
Nozzle: 200°C
Range: 185-215°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: 55°C
Range: 50-60°C. Printer max: 110°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
在 Anycubic Kobra 3 Combo 上打印 PVA 的问题排查
PVA 使用技巧
始终将 PVA 储存在密闭容器中 -- 它实际上会在水分中溶解
从干燥盒打印并在打开后立即使用线轴
温水(40-45°C)配温和搅动可更快溶解 PVA;定期更换水
PVA 与 PLA 作为主要材料效果最好,因为打印温度相似
仅当支撑质量真正重要时使用 PVA -- 它昂贵且吸水性强
支撑设置
PVA is itself a support material. Dissolve in warm water (up to 45°C) after printing. Set support interface Z-distance to 0mm for water-soluble supports.
