There are so many things to consider when 3D printing; it\u2019s almost overwhelming. We could go on and on listing the multitude of settings that need to be reviewed even before starting a print, not to mention the settings needed to achieve the best quality prints possible.One part setting that\u2019s often overlooked is the nozzle. Yet, as the last part to be in contact with the filament, it has a significant impact on print time and quality. Selecting the correct nozzle is therefore an important next step in improving your 3D printing skills.<\/p>\n

Knowledge of different nozzles\u2019 impacts on the overall 3D printing process is enough to send most of us makers off to the races. In this article, we\u2019ll review the different nozzle options on the market and help you figure out which options are best for you.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

The Importance of Nozzles<\/h3>\n<\/div>\n<\/div>\n

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, it\u2019s clear that three major characteristics are integral to a nozzle\u2019s design: its size, material, and inner diameter.<\/p>\n

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.<\/p>\n

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.<\/p>\n

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 outcomes must be reached. In the next sections, we\u2019ll detail each of these aspects separately and present a few designs available on the market.<\/p>\n

Size<\/h3>\n

The overall size of a nozzle will determine how well it can heat up the filament during extrusion. By nozzle size, we mean the physical mass and length of the part. This should not be mistaken for the bore diameter, which is a measure of the inner space through which the filament is fed.<\/p>\n

STANDARD<\/strong><\/h4>\n

There aren\u2019t that many different nozzle sizes available on the market, as the shaft length of the nozzle is dictated by the block type and size. The current standard dimensions for these parts comply with V6 hot ends and MK8 extruders, with a total length of 12 to 13 mm from the tip to the end of the M6x1 thread.<\/p>\n

VOLCANO<\/strong><\/h4>\n

The so-called\u00a0Volcano hot ends<\/span>\u00a0are specifically designed for higher speeds and temperatures, with claims of processing at least three times more plastic than the regular V6 hot ends. For such reasons, Volcanos require a lengthier nozzle, usually 21 mm from end to end to promote better thermal conduction.<\/p>\n

SUPERVOLCANO<\/strong><\/h4>\n

The third size option, although rarely seen in stock 3D printers, is the\u00a0SuperVolcano<\/a>. As the name implies, it is an even longer version of the Volcano nozzle, measuring an almost ridiculous 50 mm in length. To handle such enormous dimensions, the heater cartridge is rated for 80W and can reach temperatures of 500 \u00b0C.<\/p>\n

MATERIAL<\/h3>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Moving on, the next nozzle property on the list is the material. All nozzles produced today are made of some kind of metal due to its relatively high thermal conductivity and tight fabrication tolerances. With that said, different metals are used in nozzle fabrication. Each has unique properties, which influence the 3D printing process in different ways. Let\u2019s talk about some of the most popular materials.<\/p>\n<\/div>\n

Brass<\/h3>\n

Brass is by far the most common metal used for 3D printer nozzles. This copper-zinc alloy offers great heat transfer at a relatively low cost. However, while these nozzles tend to be inexpensive, brass isn\u2019t the most resistant material and is highly vulnerable to wear.<\/p>\n

Brass nozzles can deteriorate externally from every bump or scrape that might happen during the 3D printing process. Even though this is not immediately noticeable, the wear and tear builds up slowly over time, which can truly compromise important external dimensions of the nozzle.<\/p>\n

Special 3D printing materials like carbon fiber and metal-filled filaments contain abrasive particles that can ruin the nozzle\u2019s internal surfaces if used regularly. A damaged internal bore can compromise print quality, and the catch is, this erosion is virtually impossible to spot and diagnose. For this reason, brass nozzles are better used for printing non-abrasive materials.<\/p>\n
