eSun Cleaning Filament
eSUN eClean is a cleaning filament designed to keep your 3D printer nozzle and extruder free of build-up. With a recommended operating temperature between 160-300°C, it can remove residue from various filament types. The filament is vacuum sealed to protect against moisture and contamination. Ideal for improving filament feed smoothness and reducing clogging.
Important features
- Cleans accumulated filament residue in the hot end
- Helps prevent nozzle clogging
- Wide temperature range (160-300 °C)
- Suitable for many filament materials
- Ensures smoother filament feeding
- Vacuum-sealed packaging protects against moisture and dust
- 100g in the package
What it is
eSUN eClean is a specialized filament designed solely for cleaning the hotend and extruder of your FDM/FFF 3D printer. Rather than building parts, it acts as a maintenance tool: when run through the system, it helps loosen residue from previous prints as well as any leaked or burned filament that can degrade performance.
Important benefits
Since filament debris (such as charred plastic, burnt particles, or old material) can accumulate in the printer's heating zone, it can impede flow, cause under-extrusion, or even clog the nozzle completely. Regular use of cleaning filament like eClean maintains stable extrusion, better print quality, and a lower risk of failed prints due to clogs.

Weight: 100g
Recommended working temperature: 160-300 °C
Color: Natural (undyed)
Usage tips
-
Heat the nozzle to a temperature within the recommended range corresponding to the material last used (or slightly higher).
-
Insert the eClean filament and slowly extrude until a clean, stable flow is observed.
-
If residue is particularly stubborn, leave the filament in the nozzle for a short time at a higher temperature, then extrude.
-
After cleaning, continue with your normal filament and make sure it is inserted correctly.
Packaging & storage
The eClean coil is vacuum sealed to protect against moisture, dust and other environmental contaminants before use. This helps maintain cleaning efficiency and ensures reliability when you need it. Store in a dry place after opening.
