Why are my prints coming out stringy?

Stringing (otherwise known as oozing, whiskers, or “hairy” prints) occurs when small strings of plastic are left behind on a 3D printed model. This is typically due to plastic oozing out of the nozzle while the extruder is moving to a new location.

How to make 3D print less stringy?

To reduce the amount of stringing temperature is key. A high temperature means that the material will be more liquid, through which it can easily drip from the nozzle (even though retracted). By using a lower temperature the material is less liquid and thus less likely to string.

Why is my PLA so stringy?

A common cause of persistent PLA stringing, or other materials; is a print temperature that is too high. When the temperature in the print head is too high for the material being used, the filament becomes too viscous and watery and leaks out the print nozzle.

How do I stop PLA stringing?

Tips to Avoid Stringing

1. Tip 1: Dry PLA.
2. Tip 2: Clean the Nozzle.
3. Tip 3: Lower the Print Temperature.
4. Tip 4: Activate Retraction.
5. Tip 5: Optimize Retraction Settings.
6. Tip 6: Raise Travel Speed.
7. Tip 7: Deactivate Z-Hop.
8. Tip 8: Activate Wipe.

Can a bad nozzle cause stringing?

If, for example, your nozzle takes too long to move between two points, stringing is likely to occur because molten plastic has more time to ooze out of the nozzle. But if the extruder can travel faster, the short moves may be quick enough that the filament will not have enough time to ooze.

Can Z hop cause stringing?

Both of these adjustments happened gradually, making sure there was no change in stringing between adjustments. I do have rafts and Z hops enabled in Cura, as previous prints of this model were knocked off the base even after leveling the bed properly, and almost every time a “hop” is performed, some stringing occurs.

Does wet filament cause stringing?

Underextrusion, Stringing, Bubbles, and Oozing are issues related to the presence of moisture in your filament. If your spool is not dry, you can expect low print quality and weak prints.

How can I reduce my retraction time?

Combing Mode We recommend going for Within Infill. It will reduce your number of retractions by keeping the nozzle within the infill areas when moving from one point to another. This can increase your print time but will protect your filament.
