some people saying its smaller than the original brass nozzles, thats incorrect. Used calipers and they are the same size. the shape is a little different which is why people probably think its smaller.Every little adjustment you do to ur printer is going to affect quality. when you unscrew ur old nozzle and put this one in theres a 99% chance you are going to unlevel ur nozzle. Loosen the two screws and relevel the nozzle so ur prints arent bad.

I've been printing with carbon fiber (CF) lately which requires hardened nozzles. Supposedly, if you print abrasive filaments (like CF or glow-in-the-dark) with brass nozzles, you risk ruining your nozzle, though I've never tried it. I have been using a plain steel nozzle, which has been working fine, but I'm willing to try anything to improve my prints!One thing to be aware of, this nozzle has an 7mm outer diameter which is larger than a standard 6mm one, so you'll need a different wrench to install/remove it. That's kind of annoying, as I didn't have one on hand. I ended up using a 9/32" socket wrench which worked well enough.I did some test prints with the old steel nozzle vs. this coated steel nozzle using a CF filament and then looked at the results under a microscope. It's a little hard to tell - it's not the best microscope, and the carbon fiber inclusions make the filament a little lumpy, but to me it does look like this nozzle prints more smoothly .If you're only printing with plain, non-abrasive filaments it's probably not worthwhile to get this nozzle. However, if you need to upgrade to a hardened nozzle anyway, I'd say it's worth it. It's not too much more expensive than an ordinary steel one, and there is some (minor) improvement in the print.

I recently installed the POLISI3D MK8 Hardened Steel Nozzle 0.4 on my Ender 2 Pro, and it has been performing admirably. My primary purpose for this upgrade was to print with glow-in-the-dark filament, a material known for its abrasiveness and potential to wear out standard nozzles.So far, this nozzle has handled the task with ease. The hardened steel and nano DLC coating seem to be holding up well against the demanding nature of the filament. I've gone through half a roll of filament and haven't observed any deterioration in the extrusion quality or changes in the nozzle diameter, which is often a concern with abrasive materials.While the true test of its durability will be over time, the initial performance is promising. For anyone looking to print with abrasive filaments like glow-in-the-dark, this nozzle seems to be a great choice. It's a straightforward upgrade that could potentially expand the capabilities of your printer's hardware for dealing with challenging materials.

Had a horrible smell and a nasty sticky goo that seeped out/out of it once it got heated up for the first time. It worked OK once it was installed and I cleaned up the goo, but wow it took days for that smell to dissipate. It is also much shorter than the original nozzle that came with my Ender3 V3 KE. I went back to my original nozzle since I really only use that printer for PLA and PETG.

I am doing some glow-in-the-dark filament and wanted a hardened steel MK8 nozzle to prevent wear. I got this coated .4 nozzle from Polisi3D.It has the .4 clearly stamped on the nozzle.I haven't used it a lot, but it seems good. I'm pleased with it.
