Micro Swiss MK8 Plated M2 Hardened High Speed Steel Nozzle (.4mm)

I purchased this to replace the standard brass nozzle that came with the microswiss extruder. I have printed with the hotend for some time and started printing carbon fiber polycarbonate. This material wore down the standard brass nozzle pretty bad so I ordered the MK8 plated M2 nozzle due to its wear properties with carbon fiber and because it touted superior non-stick properties. Well these properties didnt exist. I couldnt get anything to not stick to the nozzle, no matter how low I started my prints onto the build plate. Any little amount of material that curled up stuck and then it snowballed as the nozzle just attracted more and more material until the nozzle was encased in a ball. I tried the carbon fiber PC, and PLA all with the same results. I then tried the A2 hardened tool steel MK8 nozzle and had none of the material sticking to the nozzle. I am not sure what I was doing wrong or if my nozzle has a coating defect. I did receive two nozzles due to a shipment error on Amazons side and both nozzles appear to look the same, so not sure if there is coating and its just not working, or if there is something else going on.

Its a nozzle that pees on your bed. Works fine.

Worse nozzle I have ever used. Worked OK for first print in a bowden setup with Micro Swiss hotend. I started having clogging issues after the 1st print. Cleared the clog and it would get about 1/4th way through the print and clogged again. I upgraded my setup to direct drive and reinstalled the nozzle and couldnt even start a print without clogging. I removed the nozzle and reinstalled the old A2 nozzle that came with the Micro Swiss hotend and everything is working as it should. I do NOT recommend this nozzle. Never had clogging issues with A2 nozzles. The Micro Swiss A2 has been the best cheap nozzle Ive ever used. I recommend the A2 Hardened tool steel nozzle. So much better then this High Speed Steel Nozzle.

I think for what this is it didn’t work I bought this for specifically printing carbon fiber and it just stuck to it like glue and every time I had to stop the print eventually I figured out it was the tip and switched to the original and it worked fine. I don’t recommend buying this at all maybe I got a defective one but I wouldn’t risk it.

The bar for Mk8 nozzles has been set. Its been a few months since I started using this nozzle. The coating is emaculate and the pictures do not do it justice. I literally did not need to adjust any settings to get this nozzle to work. I got well over 1000 hours on my A2 nozzle. I expect this to exceed that considerably. PLA and ABS flow great. If you have a Mk8 work horse like I do, this just adds to the consistency and reliability. Yes, its worth the money. The Chinese clones still dont make M2 with a coating. This is the benchmark. This is the gold standard. You will be hard pressed to find a Chinese clone that can match the manufacturing quality of this. If there exists one, I havent seen it.

Worked for a day. I used petg and after that it went down hill. Everything would get stuck to the side of the nozzle and nothing would stick to the bed. I switched back to the cheap nozzle and all my problems where gone. I did everything to get it to work.

just what you need when upgrading to micro swisss dirct drive/hot end combo

Works flawlessly. Wish I upgraded to .6mm nozzle sooner! Running Ender 5 Plus with Bowden Drive, Micro Swiss Hot End with this nozzle. The quality is great & improved print time.

Printing: CF PETG (260) PETG (245) and TPU (230) Smooth reliable prints. Expensive for just one nozzle but it is doing the job on my Micro Swiss Direct Drive. Extremely pleased how well it prints Atomic Filament Carbon Fiber PETG Extreme Pro (NOT shown in image). Yes I would recommend. Just wish the price was a little better.

works great, the only problem is you need a slightly bigger wrench than the stock creality nozzle
