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

I am not an expert, but I bought this for printing wood PLA and it just does that.

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

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.

Yuk!! Great for glow in the dark filament. But using stander filaments started to clog. End up replace original nozzle.

Oozing out from the treads after after a more than adequate tightening. Ruined the last print by one of those bubble bombs growing large until it drop bombed the print while I wasnt even in the room. Going back to original brass tips.

Easily clogged. For my test run I printed Benchy and printed just fine. Second one I printed octopus for something a little bit bigger and 10 mins left on my timer that’s when I noticed a bad print and the nozzle started showing some goop around it. Third print was the octopi camera case and that’s when it totally clogged.

Perfect to use for harder materials that will eventually wear out your stock tips over time

I used on my ender3. Was a easy upgrade from the brass nozzles works fine good prints.

I put quite a bit of carbon fiber filament through this nozzle, and it still prints like the first time! Excellent nozzle I highly recommend it!

Took me a few days to dial this nozzle in, but once I did I had no issues whatsoever; I was actually able to get better print quality out of this than a brass nozzle (Managed to pull off some near-SLA quality details on a miniature with the 0.4 mm which is pretty astonishing). That being said, I had to bump my PLA from 205 up to 220, and had to go all the way to 260C for PETG. Works like a charm with the half-kilo or so of carbon fiber PLA Ive printed, however. Overall, this is definitely worth the $6 if youre looking to print something more abrasive; just be ready for a big temperature increase.
