How to Avoid Stringing

Stringing is one of the most common and annoying problems with 3D printing - it leads to thin, unsightly plastic threads that give the print a hairy look.

What is the cause of stringing?

Basically, no plastic should come out of the nozzle if no force is applied to the filament. However, there may be times when material “oozes” out of the nozzle when the material is exposed to heat and melts.

When the nozzle of an FDM printer moves to get from one point to the next, that molten filament then pulls strings that solidify and adhere to the printed parts.

The thin plastic threads, which look like cobwebs or strands of hair, not only ruin the look of the print, they can also have a negative impact on the structure of the model.

What can you do to avoid stringing

In most cases, nozzle oozing can be prevented with a few simple steps such as setting the right retraction settings, selecting the appropriate print speed, and setting the correct nozzle temperature.

In our new YouTube video “How to avoid stringing” we show you exactly what you can do about stringing and how you can significantly improve your print quality with the right settings.
