This is the Anycubic official hotend for their FDM printers.
Please note since the Kobra 3 series the nozzles on Anycubic's official hotend are no longer replaceable. Anycubic has fixed the nozzle to the hotend to avoid leak of melted filaments between the nozzle and heatbreak. If you prefer to replace the nozzle instead of swap hotend, please checkout our 3rd party hotend for Anycubic printers.
