Long a standard in the industry, the 0.4mm diameter nozzle is fighting for its long standing crown as the diameter of choice for the majority of the FDM hobby.

Coming standard on machines going back to the beginning of consumer level machines (when using 1.75mm diameter filament), most people didnt even give a second thought as to why they should change to anything different.

Cue the entrance of the newest generation of printers. with printers such as the K1, K1 max, Bambu P1P, ender 3 KE and others, there seems to be a race to get the prints on the plate and off the plate faster than ever before.

Yes these printers still come stock with 0.4mm nozzles, however a simple change to a 0.6mm nozzle will flow almost double the filament with almost no depreciation in accuracy or definition of prints, allowing you to get the same print in 50% less time by a simple nozzle change.

Account for more Exotic materials dropping in price(Carbon fiber, wood infused, sparkly filaments) that require a larger diameter to extrude properly, the 0.4mm nozzle is on the ropes.

Yes it will always have a place with 0.1 and .2 mm nozzles as something for a bit finer definition but this hobbies believes, if you don't embrace the change, you will be left in the past.

The death of the 0.4mm nozzle
