¶ Problem Description
Stringing, also known as oozing, is a common issue in 3D printing where fine strands of filament are left behind as the print head moves between different parts of a print.
¶ Possible Causes
- Filament has absorbed moisture.
- Improper slicer settings:
- Printing temperature is too high.
- Improper retraction settings.
- Travel speed is too low.
- Clogged or Worn Nozzle.
¶ Solutions
¶ 1. Dry the filament or replace it with a new one.
Filament that has absorbed moisture can become more fluid when heated, contributing to stringing. Try using a different spool of well-sealed filament or filament that has been properly dried in a drying box to see if the stringing issue is resolved.
¶ 2. Adjust slicer settings
- Lower the Printing Temperature: Reduce the temperature in small increments to find the optimal setting that prevents stringing while still ensuring good layer adhesion.
- Adjust Retraction Settings: Increase the retraction distance and speed to ensure that the filament is pulled back adequately to prevent oozing.
- Increase Travel Speed: Increasing the Travel Speed will reduce the time that the filament has to ooze out of the material, making a cleaner part overall with smaller blobs due to oozing.
Increase the travel speed according to your machine's capabilities, but be careful not to exceed the maximum speed. Exceeding this limit can lead to issues like missed steps or misalignment.

¶ 3. Unclog or replace hot end/nozzle
A clogged or worn nozzle can cause uneven material flow, resulting in stringing. Regularly check and clean the nozzle. Try using a new hot end or nozzle to see if the stringing issue is resolved.
Please refer to the below articles to unclog the hot end/nozzle if needed:
