Floss™ cleaning filament is designed to save you time. 

The price you see above will get you between 70-100 full purges of your extruder. A small investment will keep your nozzle blockage free for thousands of printing hours. 

If you’ve been 3D printing for any length of time, it’s likely you’ve experienced at least one clogged extruder nozzle. And if you have, you’ll know unblocking one can be a pain in the neck (and often doesn’t completely solve the issue).

No need for a nozzle cleaning kit. A better solution is to ensure you take the necessary precautions to ensure the nozzle doesn’t block in the first place. One of course is to use good quality filament, the second is to ensure you clean the nozzle frequently.

You see every time you change a material in your 3D printer, you need to ensure the nozzle is perfectly clean. When changing from a low temperature material like PLA, to a medium temperature like ABS, usually the lower temp filament will be flushed out once the hotter material has run through. However, this isn’t always the case, and you can find some residue of the other material coming out later and embedding in your print.

You also run the risk of cooking the lower temperature filament in the nozzle, building up carbon or risking clogging it up while you print with the higher temperature material. You may have noticed different colours or black specks in your prints after changing materials in the past.

An even riskier problem is changing from a higher temperature material, down to a lower temp filament. Here you have the real risk of residue of the previous material not melting correctly, and lodging in the extruder. It’s then only a matter of time before it will clog up, as the new lower nozzle temperature will not be able to flush out the previous higher temperature material.

It’s therefore essential that your nozzles are kept clean. If you change materials frequently, using a good quality cleaning filament is essential. If you print using the same material overtime and never change, you won’t need to use cleaning filament as often, but it’s still important to use occasionally to ensure everything is clean. Especially if you’re running nozzles thinner than the standard 0.4mm.

Our cleaning filament Floss™ is specifically designed to flush out all other materials, residue and carbon deposits from inside your extruder nozzle. It does this by being a complex blend of a high adhesive quality, to absorb and remove residual filament, yet very smooth flowing to ensure it never clogs your nozzle.


How about cleaning filament instructions?

It couldn't be simpler. Load the filament just like any other into your 3D printer, and extrude (don't print with it onto your bed, it won't stick!) into thin air. You'll often see the built up carbon and material deposits from inside your extruder being pulled out with the Floss™

Floss™ is designed to work well with stubborn high temperature filaments, and demonstrates excellent heat stability; operating over a resilient wide range of temperatures. Cleaning filament temperature to print at is from around 200C up to 280C+.

We suggest using approximately 10-20cm (on 1.75mm machines) or around 5-10cm (on 3mm and 2.85mm machines) of Floss™ each time you change material in your printer. Although often just a few inches will clear everything out that it needs to.

This ensures no build up or left over material can be left behind. Alternatively if you don’t often change materials run the same amount of Floss™ through periodically, around once every 200-300 printing hours depending on the quality of filament you usually print with.

We sell Floss™ 3D Printer Cleaning Filament in 50g amounts, which should easily clean your nozzles 70-100 times, often far more. If you require Floss™ in larger spools, please contact us.

Doesn’t seem to work

Did not help to prevent or solve a blocked nozzle.

Hi Anthony, Thanks for leaving a review and I apologise for any issues you're experiencing. We are not used to hear negatives about our Floss, so I would like to get to the bottom of this issue. Would you be able to send me an email to customerdelight@rigid.ink explaining what is happening? There can be a few different reasons for blocked nozzle, so I can have a look into it and prevent it for the future. I look forward to hearing from you soon, so I can get this resolved All the best Monica
Clean as a whistle

I inserted the filament into the extruder firstly cutting a 45 degree on the end to facilitate loading and selected load filament. The printer only loads about 50mm at a time so I loaded four times to enable me to load the next filament I intended to use. The next object printed perfectly. This filament makes the whole cleaning process so much easier. Will certainly purchase again and again. thanks, rigid.ink


I was not to sure about this but could just be a gimmick.....but no it works and you need to use so little to give your printer a good clean thank you Rigidink well work its money

As Clean As A ******

You know how the saying goes and this cleaning filament does just that, getting rid of all that unwanted stuff. I really didn't think that I needed this but now I won't be without it, also it's so easy to use.

Probably the best method for keeping your Nozzle clean between changes

Absolutely amazing stuff - If Calsberg made cleaning filament it would make this - Prob the best cleaning method I have seen. Will be using this for our new printer when I get back from the TCT show in September. One point of Note- I have never tried it on the CEL ROBOX, due to the needle system, but works fantastic on the Raise, and UP printers. If there was a 10 star rating - thats what I would give it.

Hi Tom, Thank you very much for such a positive feedback! I will be looking forward to meet you at the TCT show as well :) All the best Monica rigid.ink
