What You Need To Know On Nozzle Cleaning

What You Need To Know On Nozzle Cleaning

Today we are going to simply explain 3D printer cleaning filament (& Nozzle cleaning). We'll explain why in need (and what way properly) saver for you.

It's an article no authoritative but effective article on tips

First of all, do you know nozzle clog?


A nozzle clog is when an FDM 3D printer‘s nozzle is partially or totally blocked, preventing smooth extrusion and failed to print (or even machine stop) . To fix it, people have come up with scores of techniques, from using acupuncture needles to clear the nozzle to hot and cold pulls.

You don’t have to have used a 3D printer for long to realise that regular maintenance is a necessary evil.

The extruder and nozzle need the more maintenances– in fact they’re arguably the most sensitive parts to your printer.

They’re traditionally the hardest part to keep in top condition - often you can’t tell a blockage is lurking until it’s too late.

some think nozzle it's cheap then it waste of time to cleaning,they will replace it while it doesn't work any more(just what they though)

But we could say it is another good skill to save your money and ensure you aren't afraid of nozzle clog even it could save your money.

If improperly handled, copper will cause environmental pollution. Cleaning the nozzle with environmentally friendly filament and reducing discards is also an important way to protect the environment on the earth.

PCL Filament

Cleaning filament is an FDM material made specifically for nozzle cleaning. Usually sold in short sticks or coils.They help cleanly push out stuck particles and carbonized plastic without damaging your nozzle. In many cases, cleaning filaments are actually more thorough and efficient in their cleaning than traditional hot and cold pulls.

Here we mention cleaning filament it's PCL,exactly that one your think no useful and not popular as filament printing ,you may know 3D pen often using this food.

PCL has good biodegradability, biocompatibility and non-toxicity. This is an uncommon material. Its unique properties not only limit its application range, but also enable it to be used for some very special purposes.

It PCL has some excellent properties that are very suitable for 3D printing, such as layer adhesion, which will reduce delamination caused by stress along the layer boundary. In addition, it also has excellent impact strength and durability.

However, another major feature of PCL is that its melting temperature is only 60 degrees Celsius,which is much lower than commonly used 3D printing materials such as PLA and ABS.

So, how do you use this seemingly magical material? As it turns out, it’s rather simple.

To use cleaning filament, you must first decide if it’s really the best approach for your clog. Cleaning filament only works with partial clogs, as it requires that the filament can still extrude. For full clogs, you may have to perform some hot or cold pulls, or break up the blockage with a needle before proceeding.

If you’re ready to continue,heat the nozzle up to the last temperature at which you were printing, and either manually feed the cleaning filament through or set the printer to extrude automatically. You should see the old filament getting pushed out and the cleaning filament coming out of the nozzle (pictured above). Keep extruding until no black specks or residue comes out with the cleaning filament.

By the way,a PCL can be softened in water 60℃ ,you could immersing it in a bucket of boiling water then it separates out

That’s it! Once you’re done, just unload the cleaning filament and continue printing with your usual filament!
