热床附着
BVOH 是类似 PVA 的水溶性支撑材料。它粘合到你的主要材料使用的任何热床表面。使用 50-70°C 的热床温度。BVOH 在温水中溶解比 PVA 更快。
温度调校指南
Nozzle: 205°C
Range: 190-220°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: 120°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
在 QIDI i-Fast 上打印 BVOH 的问题排查
BVOH 使用技巧
始终使用干燥剂密闭储存 BVOH -- 它实际上在空气水分中溶解
从干燥盒打印并在打开后立即使用线轴
温水(40-50°C)配温和搅动比 PVA 更快溶解 BVOH;定期更换水
与 PLA 或 PETG 作为主要材料使用 BVOH;温度相容性很重要
支撑设置
For prints requiring supports with BVOH, 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.
