E3D V6 Hardened Steel Nozzle – 1.75mm

The V6 hardened steel nozzle is abrasion-resistant and developed to last a lifetime. 3D printing with abrasives such as carbon fiber, glow-in-the-dark PLA or even filled filaments like wood fill all take their toll on a standard nozzle, where V6 hardened steel nozzle will last and last. These nozzles are fully integrated into the E3D Ecosystem and will fit V6, Lite6, and Titan Aero hot ends, and are compatible with Prusa 3D printers. E3D nozzle sizes are easily identifiable by dots drilled onto their hex flats.

Paying a little extra for a V6 hardened steel nozzle, wear-resistant nozzle makes both practical and economic sense. By the time you’ve printed a single spool of abrasive filament, you’re saving money. It also saves a lot of time as you won’t be constantly replacing worn out nozzles. And you’ll be future-proofed for upcoming materials; E3D is sure that these nozzles should be able to handle just about anything that material manufacturers think of next. Because of the thermal and chemical treatment applied to the nozzle, they do have a bit of a dark, sometimes uneven looking coloration and surface finish, and there can be a small amount of residue on the nozzles despite our final cleaning process. The coloration variance is normal and doesn’t affect function. Any residue left on the nozzle will quickly be flushed in the first few millimeters of extrusion, especially if you flush it out with an abrasive filled material! All nozzles in the series are now individually identifiable with markings on the flats of the hex head making them even more convenient to work with. See table for identification.

Fine Details
If you are looking for the ultimate nozzle in terms of precision, the V6 0.15mm High Precision Nozzles are sure to deliver. It is not as easy to use as our other standard nozzles so we do not recommend them to first time users. If you are looking to try your hand at highly detailed prints but still want an easy to use nozzle, then 0.25mm and to some extent, 0.3mm nozzles will allow you to get a feel of the particular requirements of high detail printing.

General Use
Our V6 hot ends usually come with a 0.4 nozzle as standard, and the range from 0.3 to 0.6 has become the industry standard over the years. This is a good general-purpose nozzle, which will give you a good compromise between resolution and print speed. We find that the V6 works best with a 0.4mm nozzle and 0.25mm layer heights, while the Volcano achieves very good results with a 0.6mm nozzle and 0.4mm layer heights.

High Strength and High Printing Speed
The wider the nozzle, the wider the track, and the wider the track, the stronger the print. Parts printed with large nozzles (0.8mm and above) tend to have incredible strength compared to regular prints. Having a wide nozzle also allows you to print much thicker layers, reducing the total print time drastically (more info on our Volcano Blog Post). If speed is your #1 priority, we recommend using the Volcano with 1.75mm filament, as the filament has a lower thermal mass (due to a lower cross-sectional area) and therefore heats up quicker when in the melt zone. The question here is: will your extruder keep up? Volcano comes with a 0.8mm nozzle as standard but goes all the way up to 1.2mm for very large and noticeable layers. At this size, the layers have a certain aesthetic appeal to them, we think.
