Genuine E3D Hardened Steel Nozzle V6 (1.75mm) 0.40mm (V6-NOZZLE-HS-175-400)

Quite a bit more than brass but well worth it. Lasts much longer and doesnt clog like the brass ones do.

PETG just sticks and then ruins the print. I like to print things for the outdoors and I must use PETG so this does not work for me or PETG.

If you are printing abrasive materials like wood or glow in the dark stuff often then this nozzle is great for the situation. If you only print with them now and again then I don’t think you ‘need’ this over the stock nozzle.

The nozzle prints quite nice at slow speeds under 80 mm/s. Unfortunately due to my specific setup (LDO 2504AC) I get some massive VFA when I print less than 200 mm/s and a ton of resonance at 60-110 mm/s (I normally push 228 with nickel plated copper). This has led me to raising abs temps from 265 to 290 to compensate but it just doesn’t want to flow right and adhere at those speeds due to it being steel and me now just learning about this (oops). A better fit for me would be a tungsten nozzle. Not really the nozzle’s fault because it is tough as nails and survived a slow bed crash and the blob of death along with a ton of brass brushing. I’ll just keep it around as a spare because it’s part of the funny history of my printer now.

I used to go through copper nozzles like mad. This hardened steel nozzle might be more pricey, but I havent had to worry about it as a point of failure since installing it. Highly recommended, especially if youre printing composites and carbon fiber materials.

If you need a .4mm E3D hardened steel nozzle then this will do.

Originally got this to print glow-in-the-dark filament. Initially it appeared to be causing jams, but after some troubleshooting I noticed that the filament was getting caught in a step in the middle of my heatbreak shortly after installing the nozzle, what a wild coincidence. After replacing with a new heatbreak, the nozzle prints great. I understand as a general rule, you should print at slightly higher temperature with a steel nozzle, but I noticed in my case that isnt necessary.. maybe because Im using the silicone sock? YMMV, Ill probably just leave this nozzle installed forever.

Installed on my Prusa MK3, and kept getting periodic filament jams. No amount of tuning could seem to guarantee consistent printing with this nozzle; I was afraid to leave any print unattended with it. I might try it again when I have to use an abrasive fiber in it and I can babysit the print, but until then its back to the stock head.

NO idea whats wrong with this nozzle but NOTHING comes out without curling back to it and getting stuck in a blob of crap.. ABSOLUTELY EVERYTHING attempted to print turns into a blob on the nozzle. Re calibration of the bed.. changing speeds.. different adhesion with tape hairspray or varying heat NOTHING helps... This is such a HORRENDOUS price for either A: CRAP quality control or B: a GARBAGE nozzle.. Returning it ASAP... AVOID unless you like to gamble!

Good product.
