5 Pieces Hardened Steel Nozzle 0.4 Mm/ 1.75 mm 3D Printer Mk8 Nozzles High Temperature Wear Resistant Compatible with Ender 3/ Ender3 Pro, Prusa I3, Makerbot Creality Cr-10 All Metal Hotend

Seem to work pretty good

The nozzles have been working great

I've been 3D printing for 4 years at this point and, until I got these, never had a clog. I've used brass nozzles on several occasions, and to my surprise, these ones clogged on me while printing some parts. I'm willing to give it the benefit of the doubt and say it's the filament I'm using, but I find it strange that I've used other brands very consistently with no issue, but as soon as I switch to this one, I'm getting issues. Asides from the clog, it's extremely robust and when I took it off I probably could've brushed the outside and have it look brand new again even after dozens of hours of printing

Was a little worried with some of the reviews about the nozzle tip sizes being inconsistent. My pack of tips came with a sticker to verify their authenticity, no issues they’re they are all uniform. Ran it through about 4 hours of printing no issues. I’m very pleased with the quality of the prints. The only weird thing is that it’s not flat on all sides like the factory tips so you’ll have to carefully use a set of pliers to install these steel tips. So far so good no complaints, definitely worth the $

I bought these for my glow in the dark filament, as it's a tad more abrasive than generic pla. However, I would recommend adjusting your printing temperature to compensate for the heat loss in your print. Overall, as long as you have the experience to work with different filaments, I definitely recommend keeping some of these handy for your ender 3 printer .

I got these for my ender 3 S1 pro, I run a glass bed also, I was experimenting with carbon fiber and wood pla, which requires a hardened steel nozzle, they work great, made great, and I use them for all types of PLA no matter if it's abrasive or not, a cheap upgrade that will save you in the future

Regardless of whether these print well is besides the point, not having standardized head for using normal tools, sockets makes it a complete failure of a product. I was unable to validate it's printing since i was unable to fit an adjustable wrench in the area to properly tighten it. Sure I could have found a work around but that is besides the point. It seems to me that the size of the head at 5.9mm is a tooling failure in manufacturing and complete lack of quality control. I won't trust any product that has that type of failure for printing high temp corrosive filaments which is exactly what Hardened steel is for.

I’ve printed about 1.5kg of high temp carbon pla blend (very abrasive), 1kg of Glow (slightly abrasive), and probably near 4-5kg of regular old PLA and it still looks/functions like brand new. They are a direct replacement for the stock ender nozzle. Some people complain about quality control, so maybe I lucked out, but I’m also going to order another 5 just to have on hand and see. I also did NOT have to adjust any hot end temps as some have mentioned, again maybe I’m just lucky, but all in all I really like these nozzles. I Have had very bad experience with some other brands that printed fine for a day and then just clogged and jammed and clogged and jammed but these have been mint! Was skeptical due to the low price, but like w many brand name items, half the cost is just the name.
