How to clean a nozzle with melted filament around it.

Posted · How to clean a nozzle with melted filament around it.

What is the best way to clean a nozzle. I am not talking about a "clogged" nozzle but a nozzle that has a bunch of melted PLA around the top. Do you use soap and water? Other chemicals? Do I need to heat it up first before cleaning?

Any advice would help!

thanks

    You only need to heat it up a bit and then you can pick it all off.  100C or even only 80C is plenty.  boiling water or just a hair dryer.  Not too hot to touch or maybe just a little too hot to touch.

    You can also do this:

    Heat up to lets say 180°c and take a piece of filament, put it against your nozzle and make it melt on the areas you want to clean then cool it down like you do for atomics and continue pressing it on the nozzle, when it cools down the burned plastics will be caught by the melted plastic.

    Then pull the filament gently and it should peel off the residues.

    This can probably also work if you only heat up to 140°c and "brush" your nozzle with some filaments

    I usually heat it up to about 200°C and then wipe it with a thick (!!!) paper tissue. If I am around when the printer finishes printing, I immediately wipe the outside before it is cooled down.

    Heating the nozzle up to about 120°C (depending on the material) and then wiping it with a piece of scrap filament also works.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
