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!
