Does My Filament Need Tip Shaping?

If your filament is in this list, then it likely won't need tip shaping, and you can use the No Tip Shaping feature:

  • PLA (not Silk, Matte, or glitter variants)
  • PLA+ (including PLA Pro, Tough PLA)
  • PETG

If you filament wasn't in that list, continue reading this page.

Blobby Tips

If your filament tip has a thicker tip after unloading, you can do two things:

  1. Print hotter
  2. Decrease cooling moves

Stringy Tips

If your filament tip has a stringy tip after unloading, you can do two things:

  1. Print colder
  2. Increase cooling moves

You may also be able to use the No Tip Shaping feature.

Hook of Death

If you filament tip can't unload out of your extruder and forms a hook shape, you may need to replace the PTFE tube between your printer's extruder and hotend. You may also want to follow the recommendations for Blobby tips.
