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

Works great. Wish it was cheaper

I bought this nozzle because I was tired of blowing through brass ones. I mostly print PLA, and while the occasional PLA print isnt enough to burn out a brass nozzle very quickly, printing for a few hundred hours every month certainly can, in my experience. Fit and finish seems very consistent, and the nozzle lets a high E string from a guitar slip through clean, though those run smaller than the 0.4mm the nozzle is supposed to be, so I cant verify the internal diameter. I had to raise my printing temp for PLA from 195C to 215C (an increase of 20C) to get PLA to extrude properly. An alternative may be allowing the hotend to pre-heat for 10-15 minutes prior to running a print, but many of my prints only take that long in general. Also, while I was previously able to use 6mm retraction with the brass nozzle, the steel one seems more temperamental about retractions beyond 4-5mm (which, to be fair, is the maximum suggested retraction rate from E3D themselves). It is worth noting that, if your print quality is absolute garbage after using this nozzle, your unit is defective. This happens at a certain rate in precision machining. If this is the case for you, request a replacement immediately. In the past, E3D has allowed me to return one of their products with the same fault 5 times in a row until I got a working one. It happens and is unfortunately just part of mass production of precision equipment. Overall, its working fine so far. Ill update this review if any serious issues arise. Follow-up: After having a few patchy prints arise after changing to another spool of filament, I found that the E-steps and flow rate needed to be adjusted. This makes me think that either the nozzle diameter isnt quite right, or the pocket inside of the nozzle is larger than in the brass ones. In any case, simply updating your E-steps and adjusting the flow rate accordingly got rid of the problem. Im also getting prints on par as with my brass nozzle, so people who are saying this nozzle ruins their print quality either received defective units or didnt re-calibrate their printer to support the new nozzle.

I do a lot of printing and I tried this as an attempt to reduce consumption of brass nozzles. The result was a reduction in print quality that I couldnt tune out. Not to blame the manufacturer, I just think hardened steel nozzles should be reserved for abrasive materials ONLY.

This Nozzle has worked very well for me. Prints clean and reliably. Handles everything I put through it including abrasive CF material. Occasionally had to retighten, and had to add an extra 5° C to print settings to compensate for heat conduction being slightly less than brass.

Likely received a defective nozzle. Nozzle is either extremely poor at conducting heat or inner diameter is far smaller than advertised. Underextrusion perpetually to the point where extruder motor is clicking from gears slipping due to too much resistance. Though it improved the higher the temp got ( up to 260* c for PLA!) I found no way to compensate in order to make this functional for any print.

it works just like it should. so i bought more hardened nozzles for other printers that i own.

Perfect fit with high performance and long lasting wear. A must for abrasive filaments like luminous and metal compounds.

I have a Prusa MK3 and decided to grab a steel nozzle for more abrasive filaments. So far this steel nozzle has been working great. It was a quick install from my .4 brass stock nozzle. But ive had no issue with extrusion or clogging at all. The only issue ive had was operating temps. I have to go up as much as 20c to get this to print as well as my brass one. But other than that, its been a great nozzle. I highly recommend it for your E3D hotend.

I can swap a nozzle in less than 30 seconds. Ive never had a new brass nozzle wear out mid-print with carbon fibre. I dont know anyone who has. Yes, brass wears out... eventually. So will hardened steel...eventually. I can buy 24 brass .4mm nozzles for $8, delivered tomorrow. Thats 34 cents a piece. The cheapest decent hardened steel runs $23. Ergo, 74 brass nozzles for 1 steel. Stick with brass, and I dont have to worry about temp variations or anything, really. So, why bother? Out.

I bought 2 for my 2 prusa mk3s. One clogged immediately, which could have been the glow in the dark pla and the nozzle being too hot. But the second one worked for about a week then made uneven extrusions that couldnt get passed a 3rd or 4the layer. I changed the nozzle back and everything is working fine. Pretty annoyed that both nozzles had issues. *Update I returned the problem nozzle a month ago to get a replacement and still have not received a refund or replacement. *Its been two months. The second nozzles bore is also not straight. Very displeased with the amount of headache this has caused me. I straight up want a refund for both nozzles. The return on the first nozzle has still not been processed
