Formfutura Galaxy clogging AA04

[aag 6]

I need to print optically-reflective material. I have tried to use the Formfutura Galaxy filament, which is spiked with aluminum flakes. However, after 300g of print, it clogged the AA04 printhead irreversibly. I cannot manage to unclog the printhead, not with a cleaning filament and not even by raising the temperature to >300°C. The Formfutura specs say that the filament is not abrasive and do not say anything about caution with nozzle size. Is this something that is known? Ruining printheads is a rather expensive side effect...

Well you can try to dissamble the nozzle, clean it and put it back. I've used guitar strings or bristtles from a metalic cleaning brush to save an clogged print core. On the next print I checked more often that there was no leakage at the nozzle.

 

I don't know that material but can a 0,8mm print core being a better solution?
