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

Seems to work better than other harden nozzles, for me at least. Prints are sticking good and smooth. Stays sharp for a while, at least 1 week continuous printing with various PLAs like wood, carbon fiber, pla+. Have not tried other materials yet, but will soon. Overall this is good priced and works great

Nice price

Building a fully dynamic F-18E Super Hornet cockpit, wanted to use Carbon Fiber PLA on some of the parts, specifically parts for the landing gear lever. I was having problems pushing it through a .4 nozzle, got the .6 and the .8, they were clearly labeled on the packaging for size, and marked on the nozzle itself. Used the .6, it has worked flawlessly, I cant express what a fantastic nozzle this is, put it on the hotend, leveled the bed, and it laid that carbon fiber PLA down perfectly, and really does still maintain the detail. Couldnt be happier with this nozzle, kudos to them for a fantastic product, I will be stocking up on more from them.

works great

really good

Good clean prints so far with initial testing. Bump your temps up 5-7 degrees across the board though. I had multiple prints fail after the 3rd or 4th layer due to filament backing up in the nozzle. Higher temps were an easy fix.

Pretty good, just sucks you cant tell what size it is bc there no ingrained on it

With the original ender 3d printer ....its a must have upgrade

I will need to update. Havent tried to print anything yet. Looked under microscope and seems less round than free nozzle that came with some filament. Could be a brass vs steel thing but seems very rough. Maybe performance will be fine. Ive attached a photo of each.

Terrible product for the price do not waste you time thinking your buying a nozzle that will last and be high quality beads layed down... You wont this product lines were not consistent looks to be a bur on the inside opening of the nozzle crap you guys sold me metal rabbit turd
