Three Major Characteristics Are Integral to a Nozzle's Design
Dec 31, 2021
Stainless Steel Nozzle
The nozzle is the mechanical part of the 3D printer that extrudes the filament. It conducts the thermal energy provided by the heating cartridge and block to the filament, melting it. Based on this information, one could assume that three major characteristics are integral to a nozzle’s design: its size, material, and inner diameter.
The bigger the nozzle, the more mass and surface area available for transferring heat to the filament, making this process more effective and capable of higher extrusion speeds. Thermal conduction also relates to the nozzle material, as each material conducts energy differently based on its properties.
Lastly, the inner diameter of the nozzle affects the amount of plastic extruded per second, a property known as flow, which also determines the maximum extrusion speed. The inner diameter also relates to final part accuracy: Smaller diameters allow for thinner layers and walls to be printed.
In summary, all three nozzle characteristics can have a large impact on how long your part takes to print as well as the quality of the final object. Usually, a compromise between these two factors must be reached. In the next sections, we’ll detail each of these aspects separately and present a few designs available on the market.
The nozzles manufactured by Etone Technology are utilized in various industries, such as in 3D printer, automotive fuel injection systems, EGR valves, and more.
