A nozzle is consumables.
The replacement is recommended every six months for 3D
printer businesses and every one year for individual users.
However, the replacement cycle may vary depending on the
usage.
The additional nozzle is included in the toolbox as a
basic component when purchasing a printer.
An additional purchase is available at the Cubicon
website or retail stores.
