3D Printing Dictionary
The nozzle is the end of the hot end where the hot extruded plastic exits. Common nozzle sizes have orifices of 0.35mm, 0.4mm and 0.5mm. A smaller nozzle orifice will produce a finer extruded filament at the cost of a lengthier print time and potential errors during a print. A larger nozzle orifice is generally more reliable with a shorter print time while reducing overall quality.
