The Flashforge Creator 3 nozzle has been specially developed for the 3D printer of the same name and is made of stainless steel with a diameter of 0.4mm.
Ideal as a replacement nozzle or as a spare part so that you have your own nozzle for every type of filament. When replacing the nozzle, make sure that you mount it well against the heatbreak so that no space is created here. This can cause a build-up of filament and a leakage.
