cleaning 3D printer filament


Cleaning Filament - 3.00mm
Free Gift



This cleaning filament from eSUN is a thermoplastic purging compound safe for use in all 3D printers! Purge your extruder and remove residual material to maintain your 3D printer.

The cleaning filament is especially useful when changing from a high temperature filament (Like Nylon, Polycarbonate etc.) to a low temperature filament (Like PLA) or changing from a dark color filament to a light color filament.

It is also very useful to purge the extruder after using composite materials (Like Wood) to remove any remaining particles.

It is also good practice to use the cleaning filament before and after printing sessions so that when your printer is turned off and cooled down, no residual material hardens inside.

Cleaning filament is NOT designed to create any 3D objects, it is only designed to be used as a maintenance tool for your 3D printer.

The cleaning filament comes in 100 gram coils, but all you need is about a 100mm to 200mm piece each time. So each coil will last you for approximately 150 to 300 uses!

Can be used to clean between 150°C to 320°C which means that you can purge the extruder from any filament/material type that falls within that temperature range.

Cleaning Filament Instructions:

  1. Set your hot-end to the temperature you used for the last filament printed with.
  2. Unload any remaining filament from your extruder.
  3. Insert a short piece (100mm-200mm) of cleaning filament and extrude the full amount.
  4. Set your hot-end to required temperature for the new material you are going to print with and proceed as normal.
