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

Used this after a clogging issue. Cleaned the extruder just fine. would recommend this one!

This has quietly proven its worth in my 3D printing endeavors. Since encountered many issues related to the hotend with constant blockages, and partial clogging. I though it best to give this filament a shot!While it might not seem 'essential' it plays a crucial role behind the scenes, in reality.It excels at eliminating any and all residue stock inside the hotend, and it keeps my printer's nozzle in top shape. It's fixed so many issues, and has saved me a bunch of money on replacement parts!Its super convenience, it's easy to feed in the printer, and to do a cold pull. It's totally changed my maintenance routine, allowing me to focus more on the discovery of 3d printing.A truly underrated tool, I would recommend to anyone who owns a 3d printer!

When you have been using colours like black it needs something to help remove the residue. This does seem to work. This does seem to be the only affordable one avaliable on amazon. This brand of filament is not one I would normally buy because in my experience its basically unusable. But as this is not being used to print anything I thought it would probably be OK. Apart from being overpriced it's basically good.

Use a bit every time when changing from hot to cooler filament (e.g. ABS back to PLA). Allows purging at the higher temperature but then will be purged out itself when loading the new filament at the cooler temperature. Saves on blocked nozzles.

I was a bit skeptical but this cleans out the residue of previous filament. You can actually see the colour change. It doesn't need much at all so a spool will last a long time. I don't cold pull it, I just feed it through at the temperature of the previous filament and works ok.

Recently my Prusa MK2S started clunking when trying to pull filament, and then noticed it was not printing. I cleaned the nozzle with a needle, but then purchased this as well so could run through. I only ran this through until clear but got rid of a load rubbish in the nozzle/heat element. I would do a cold pull through with this, but I am not that brave and don't wont it to snap.This cleaning filament as a slight sticky texture to it, and feels softer than PLA/PETG, hence do not want to do a cold pull.Will continue to use this between different filament types and then every so often to ensure get no more blockages.This was alot more reasonably priced than other stuff had seen. Am glad I managed to get some and run some through.Would definelty recommend if you want to maintain printer in good condition.Only negative would be no instructions, but you can find how to use this stuff online. So still giving 5 stars, as does what is meant to.Now to try there PLA filament as well.

This will last a while, it doesn't take much to clean a nozzle. I don't use it every time I change filaments, but for massively different types with different temperatures, it's a reassuring way to possibly make expensive nozzles last longer. Only time will tell, but for all the time and cost of this product, I think it's good practice, and the visible results of the old filament being cleaned out make it satisfying, if not ultimately necessary.

Did the job well and cleaned out my nozzle as I would have liked. However, it would have been a good idea to put the temps needed on the pack? Surely one little sticky label would not have broken the bank?
