热床附着
回收 PETG 与标准 PETG 粘合 -- 有时过度粘合。在光滑 PEI 上使用有纹理的 PEI 片或涂胶棒作为脱模剂。移除打印件前让热床完全冷却。
温度调校指南
Nozzle: 238°C
Range: 225-250°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: 83°C
Range: 75-90°C. Printer max: 100°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
在 Bambu Lab A1 上打印 Recycled PETG 的问题排查
Recycled PETG 使用技巧
以与标准 PETG 相同的方式处理回收 PETG -- 使用前干燥,30-50% 风扇,光滑 PEI 上胶棒
质量在品牌间变化;找到可靠的供应商并坚持使用
回收 PETG 更环保,与原生 PETG 具有几乎相同的机械特性
某些批次可能有更多拉丝;根据线轴调整回抽
支撑设置
For prints requiring supports with Recycled PETG, 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.
