eSUN 1.75mm, Cleaning Filament, Prevent Nozzles and Extruders Clogging, 100g Spool 3D Printing Filament for 3D Printers, Natural

Had some issues, this helped. I now use it fairly often. Works at many temps and has done well to clean out nozzles.

I use this about every other print. Helps keep extruders clean. Only need to use a little bit and it goes a long way. Great value for the money.

I had all sorts of clogging and adhesion issues when switching from 1 type of filament to another. Purging in between with this cleaner filament solved that majority of the issues. I purge all the time now, 200mm and never have issues.

I use this cleaning filament every time I change styles of filament and when changing from a higher print temp filament to a lower print temp filament, such as changing from PETG to PLA. Greatly reduces the chances of filament jams. You are missing out if this isn't in your 3D Printer toolbox, highly recommended!

Used only a foot (.3 m) and revived my all in one nozzle on my Flashforge adventure. Did as advertised. Little finicky. You might need to help it catch on the feeding gear.

The filament works just great for cleaning up 3D printing nozzles.Waste filament and residue adheres to cleaning filament and you can watch how that waste sticks to the cleaning filament once extruded.Works great, product is of great quality and is a must to keep the printing nozzle in good condition and prevent unnecessary clogging. Totally recommend the brand.

This helped me get my nozzle cleaned up

I was looking for solutions to my adhesion issues on my printer. A lot of prints had lines that lifted, or just would print spaghetti. After leveling my printer countless times, cleaning my build plate and checking my slicer settings, I came across coldpulling and nozzle clogs in my search for fixes. I ordered this filament, so that I could try coldpulling and feeding it. Fixed my problems instantly. 100gs is more than enough, as I'm yet to get to half of this spool.
