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.

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

Working good on my Neptune 3 pro.

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.

I wanted to print some large parts (about 1.2kg total), with no detailed features, in carbon fiber PLA, as fast as possible. I used this nozzle with a 0.4mm layer height, 0.8mm width and the results were good. No noticeable wear and tear on the nozzle. I normally run PLA at 200c with 0.4mm brass nozzles, but had to bump it up to 230c, and drop the print speed to about 25mm/s (overall print time is still way shorter than a 0.4mm nozzle at 60mm/s). If you do the math, 25mm/s at 0.8mm is about the max a normal V6 heater block can melt. If you want to go faster, youll need a higher power heater. Great nozzle.

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

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.

Microzwiss nozzles are great, the print quality is perfect, they are clearly labeled, and the M2 hardened steel eats abrasive filaments like its nothing. You might have to bump your hotend temp up a couple bits since the hardened steel doesnt transfer heat as efficiently as brass, but all it takes is one temp tower and you wont have to change your nozzle for a long time. 100% worth the price
