Fast printing PETG filament

As Bambu Lab are out of stock of their PETG-HF (High Flow) filament, worldwide, I have been forced to try other makes. I should point out, that apart from the odd specialist filament, like TPU, I now almost exclusively print using PETG. I mainly print functional parts and they are often for use inside cars, where the heat resistance of PETG is needed to avoid warping.

As mentioned in an earlier article, I want to be able to use an alternative filament as a direct replacement for the Bambu Labs version, without the need to change any settings on my Bambu Lab H2D.

These are my comments on the Bambu Labs filament:

==

Bambu Lab PETG-HF

• Print settings: Automatic defaults.
• Print Result: Good. Negligible stringing, few blobs.
• Surface: Satin to matt.
• Spool AMS compatibility: Good (OD 200mm, ID 55mm, Width 67mm)
• Print fails: None.

Having read some reviews I have tried out the following. These are in the order I tried them:

==

Sunlu Rapid PETG

• Print settings: Same as Bambu Lab PETG-HF.
• Print Result: Good. Negligible stringing, few blobs.
• Surface: Satin to matt.
• Spool AMS compatibility: Good. (OD 195mm, ID 63mm, Width 59mm)
• Print fails: After lots of hours of prints, one clogged nozzle.

Tinmorry Rapid PETG-eco

• Print settings: Same as Bambu Lab PETG-HF.
• Print Result: Good. No stringing, few blobs.
• Surface: Satin to gloss.
• Spool AMS compatibility: Good (OD 197mm, ID 53mm, Width 56mm)
• Print fails: None.

Eryone Hyper Speed PETG

• Print settings: Same as Bambu Lab PETG-HF.
• Print Result: Very Good. No stringing, no blobs.
• Surface: Gloss.

Subjective Views

The results above are my opinions after a relatively limited number of hours printing with each filament. This is not an organised review or test, this is just a reminder to myself of how well filaments have performed for me.

AMS Compatibility

Being easy to use in the Bambu Lab AMS 2 Pro and AMS HT is important for me. In my results above, I am referring to those two AMS's. I have no access to any other AMS's to try them with.

Cardboard Spools

Cardboard spools are not recommended by Bambu Labs for use in their AMS's. As the cardboard wears on the rollers, the dust formed is not conducive to the operation of the AMS over time. My solution is to use an overlay spool that sandwiches the entire cardboard spool. The running edge is then plastic. As long as the cardboard spool has an overall thickness of 60mm or less and an overall diameter of 200mm or less, the result easily fits in the AMS.

Conclusion

All the filaments that I have tried, so far, are good and can be used as direct alternatives to Bambu Lab PETG-HF.
