How bad is it to print Nylon in a standard AA 0.4 nozzle?

Hi everyone!

 

Just bought a filament from the Smartfil brand called "NylonStrong" and I was wondering how bad can the filament affect a standard AA 0.4 nozzle.

This filament is intended to print between 250 / 260ºC and the printing bed should be at 90 / 100ºC.

 

The brand even advises:

Due to glass loads, this material is highly abrasive so to avoid wear in brass nozzles it is necessary to use hardened steel nozzles.

 

What are your thoughts? Should I definitely not print using a standard AA 0.4 nozzle?

    Normal Nylon is no problem to print with AA cores but glass or carbon filled Nylon can quickly wear out your nozzle. Depending on the material one spool could be enough for that.

     

    I would not try it, buy a CC core and you are one the safe side.

     

    But if you just need to print something once, then print it with the AA core but be prepared that you should replace it. But the AA is much cheaper than the CC.

    Oh no.. I tried to print on PLA a simple object right after tried a small Nylon object and now the extruder is clogged and I can't unclogged it, even with clean filament..

    What do you suggest to unclog the extruder??

    Try to heat up the nozzle to the nylon print temperature and try again the clean filament. If it doesn't help, you can try to push gently with a small needle through the nozzle. It could be that the glass fibers are clocking your nozzle. Thats also the reason why most abrasive materials should be printed with 0.6 nozzle.

    Yes, will try with a needle with 0.4mm or less! Thanks!

      • 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
