التصاق بالمنصة
PETG bonds extremely well to smooth PEI sheets -- sometimes too well. Use a textured PEI sheet or apply a thin layer of glue stick as a release agent on smooth PEI to prevent damage. On glass beds, always use glue stick (PETG can pull glass chips off). Let the bed cool completely before removing prints.

Nozzle: 245°C
Range: 230-250°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: 80°C
Range: 80-90°C. Printer max: 100°C.
- First layer lifting? Increase +5°C
- Elephant's foot? Decrease -5°C
- Let the bed fully preheat before starting
استكشاف أخطاء PETG على Bambu Lab A1
نصائح احترافية لـ PETG
Dry your PETG before printing -- even a new spool left open overnight can absorb enough moisture to affect quality
Slow down the first layer to 15-20 mm/s for solid adhesion
Use a lower fan speed (30-50%) -- too much cooling weakens layer adhesion with PETG
If printing on smooth PEI, use glue stick as a release agent to prevent bed damage
PETG is an excellent all-around material once you dial in the settings

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.
