热床附着

PETG 与光滑 PEI 片粘合极强 -- 有时过强。使用有纹理的 PEI 片或在光滑 PEI 上涂薄层胶棒作为脱模剂以防损伤。在玻璃热床上,始终使用胶棒(PETG 会拉掉玻璃碎片)。移除打印件前让热床完全冷却。

温度调校指南

Nozzle: 240°C

Range: 230-250°C. Printer max: 350°C.

  • Poor layer adhesion? Increase +5°C
  • Stringing or oozing? Decrease -5°C
  • Print a temperature tower to find your exact sweet spot

Bed: 85°C

Range: 80-90°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 Bambu Lab H2D Pro 上打印 PETG 的问题排查

过度拉丝降低温度至 230-235°C,提高回抽速度至 60 mm/s,并干燥耗材
雾蒙或粗糙表面将风扇速度降至 30% 并略微提高温度
粘合过紧让热床完全冷却后再移除;在 PEI 上使用胶棒作为脱模剂
脆性打印件可能受潮;在 65°C 下干燥 6-8 小时

PETG 使用技巧

1

打印前干燥 PETG -- 即使是新线轴开放过夜也会吸收足够的水分影响质量

2

第一层放慢至 15-20 mm/s 以获得牢固粘合

3

使用较低的风扇速度(30-50%) -- 过度冷却会削弱 PETG 的层粘合

4

如果在光滑 PEI 上打印,使用胶棒作为脱模剂以防止热床损伤

5

PETG 是出色的多功能材料,一旦调试好设置

支撑设置

For prints requiring supports with 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.

PETG 速览

优势

  • Excellent all-around material for functional parts
  • Good impact resistance (much better than PLA)
  • Moderate heat resistance (softens ~80C)
  • FDA-approved for food contact in raw form
  • Good chemical resistance
  • Semi-flexible (bends before breaking)

劣势

  • Prone to stringing
  • Moderate moisture sensitivity
  • Can bond too strongly to glass beds
  • Lower fan speeds required (not great for overhangs)
这些参数是基于厂商规格和社区经验的推荐起点。请先做测试打印并按需调整。具体参数可能会因你的打印机状态、环境和耗材批次而有所不同。
