1piece High Temperature Sharp Hardened Tool Steel MK8 Nozzles 0.4mm for 1.75mm Makerbot, Creality CR-10 All Metal Hotend, Ender 3/ Ender3 pro, CraftBot, Prusa i3 3D Printer

Worked great but after 30 hours of print started to act like a stock tip does with carbon fiber going through it

very good !!!

I could not get this nozzle to work well on my Ender 3 Pro. Please keep in mind maybe i am doing it wrong. However i used other nozzles on my printers perfectly fine. But this one would not print right, I think I got the wrong size! It looks smaller than my usual 0.4 Nozzles. Perhaps this is why. It also leaked on me alot.

Really last long and is good for materials that are rough, but it needs to run at higher temps.

The nozzle is too short. It sits too deep into the nozzle assembly, and you cant get the wrench on it to tighten down.

Fit my Bibo 2 printer perfectly

so i ordered the .6 nozzle for a carbon fiber project im starting. for the last week ive been scratching my head trying to figure out why i cant get a good first layer print. ive had so many problems with adhesion and lines being to far apart and for the life of me i couldnt figure out why. i changed every setting i could think of. from line width first layer width and layer heights. nothing worked perfect like it used to. i had problems with my extruder skipping and took it all apart cleaning and checking it. and today i finally was about to give up on it and throw the printer out the window till i thought maybe ill check to see if i ordered the right size nozzle. which i did. i ordered the .6 like i thought i did. and here is my main reason for only giving 1 stars. there is no size markings on the nozzle. no way of telling if you got the right one. so in a last ditch effort i changed all my settings to the usual and put the nozzle size to .4 and what would you know. perfect prints. there is no doubt in my mind this nozzle is a .4 nozzle even if the bag says its .6. ive waisted about 5 days and a bunch of filament trying to get the settings right. im printing something right now and it is near perfect with .4 nozzle settings. highly disapointed it took me this long to figure it out. wont be ordering any nozzles without the size marked on the nozzle.

I bought this less than a week ago, I got through 4ish prints and started getting all messed up on every job, thought the bed wasnt level, re-leveled, did everything else, then I changed the nozzle to a brass one and have had 0 issues

Ive had this nozzle a while its held up perfectly but an issue Im running into is now is that the size of the nozzle isnt on the nozzle anywhere. I had to come to my Amazon order history to confirm that I ordered a .4mm. Maybe I could eyeball it against another .4mm brass nozzle but thats not great. Currently this is the only hardened nozzle I own but that will be changing soon. Ill have to be sure that my next nozzle has the size on it so I can at least use process of elimination to identify this one as the .4

Works great. Wish I had tried 0.8 mm earlier. Such a time saver. Using it for carbon fiber infused. No clogging at all. Works great for all filaments though
