Replacement nozzles for E3D hot end available in 0.25-0.8mm orifice for 1.75mm filament. Note that we have moved the 3mm options here V6 nozzles are designed for use with the E3D V6 heater block. Modify your HotEnd to print with small nozzle orifices to achieve fine details or larger nozzle orifice sizes for more substantial, stronger 3D prints. 1.75mm Brass V6 nozzles are fully compatible with the Prusa 3D printers. Brass nozzles, featuring E3D’s signature internal geometry, have optimal thermal properties for everyday printing, providing smooth layers for standard non-abrasive applications. Rated to a max temperature of 300°C. Note that the standard hotend is brass. This is the best choice for most materials. However, for abrasive materials such as carbon fiber, glow in the dark, and stainless and iron filled materials, the stainless nozzle will provide a longer life. However, while the stainless is a longer life, it is lower thermal conductivity than brass so higher temps and/or slower speeds may be required. The large bore has been elongated to give a minimum small diameter nozzle length. This reduces the potential for clogs.

Sanjay did a perfect job of explaining it, so we’ll just repeat his words! From the E3D Blog: Nozzle Specificity and Identifiability. While we were in the process of going over the nozzle we thought we’d address making them easily identifiable on a per-size basis. It’s fairly obvious whether a nozzle is 1.75mm or 3mm, but telling the difference between a 0.35mm and a 0.40mm is incredibly hard, and that’s before they get covered in plastic. To that end we have added spots drilled onto the hex flats of the nozzles, the number of which corresponds to a specific size of nozzle. The more dots the bigger the nozzle. We did consider using a binary code, but decided that we didn’t need 64 different sizes of nozzles in the end – maybe one day. When a nozzle is printing it is not only outputting a stream of plastic, but also flattening it into its final stadium cross sectional shape. The width of this printed track is wider than that of the nozzles small diameter hole, as such the nozzle tip needs to have a flat on it that is at least as wide as the widest sensible track width. Because the widest sensible track width varies depending on the nozzle diameter it logically follows that the tip flat diameter should vary with the nozzle diameter. Phwwoooar look at that proportional orifice-tip-flat relationship! This means that with our larger 0.60mm and 0.80mm nozzles you can lay down fatter wider layers than ever before. This is great for large fast printing of super-strong objects, Nylons in particular benefit from being printed from big nozzles. Additionally you can create beautiful very glassy looking objects with big layers of PET type materials like _XT , T-Glase and Polycarbonate. **edit: A large diameter nozzle is also absolutely awesome for printing filled materials like woodfill and carbon fiber PLA. For our smaller nozzle this means you can get even greater resolution and print smaller details and features in your objects. The smaller tip flat allows you to put down those small features and details without an over sized tip flat smudging the tracks adjacent to what is being printed. These nozzles are also backward compatible with v5 and v4 so you can use them on existing hotends if you want to get some proportional orifice-tip-flat relationship goodness in your life without swapping out the whole hotend. Note: V6 style nozzles can be installed on the Original Prusa MK4/S, CORE and XL 3D printers with the Nextruder V6 Nozzle Adapter (sold separately).
