my easyArts printer 's nozzle was stuck,

my easyArts printer 's nozzle was stuck, which printer nozzle I could by on Aliexpress for replacement?

Thanks!

Mine came with a .5mm nozzle, and I use that number on all my Cura models and it works well. I guess they went with the .5mm over the standard .4mm because of the Bowden extruder- less resistance in the filament. Good luck

According to the manual (User Manual21051203.pdf - Google Drive), the original Ares 3D came with 0.4mm as default, although it accepts 0.3mm.

By stuck I assume you mean jammed with filament? I have always used 0.4mm nozzles with my Ares. They are pretty easy to find as they are super common.
