Nozzle
Manufacturing Engineering · Aerospace Engineering · Last updated: July 30, 2026 · How this entry was written
Definition: A precision orifice at the tip of a 3D printer's hotend through which molten filament is extruded onto the build platform.
Example in context
“We swapped the 0.4 mm nozzle for a 0.8 mm one to speed up the infill printing of the large part.”
“Büyük parçanın dolgu baskısını hızlandırmak için 0.4 mm nozülü 0.8 mm ile değiştirdik.”
Where engineers use it
Nozzle diameter determines layer width and resolution; engineers select it based on desired print speed and detail requirements.
Synonyms: tip, orifice
In Aerospace Engineering
A shaped duct that converts pressure and thermal energy of a gas into high velocity directed flow. In propulsion it sets exhaust velocity and therefore the thrust produced by the engine.
“The converging diverging nozzle expands the exhaust gas to ambient pressure, converting thermal energy into useful exit velocity.”
Practice: can you use “Nozzle” at work?
A technician is troubleshooting under-extrusion on a production printer and needs to decide whether to clean or replace the nozzle. What steps would you recommend?
Show a model answer
“Inspect the nozzle regularly for wear or clogs to maintain print quality.”
