Micro Swiss MK8 Plated A2 Tool Steel Wear Resistant Nozzle (MakerBot, CraftBot, Creality, CR10, Ender 3, Ender 5, Tevo Tornado) .4mm

I almost exclusive print with carbon fiber polycarbonate and this nozzle has now ran through two full spools and hundreds of amazing prints the only thing I wish they would do is add a non stick coating to the outside.

Used this with my Creality CR-6 SE. Re-leveled the bed with the nozzle installed. At the proper Z-offset, I had constant issues with prints not adhering to the bed. Lowered the nozzle and it would smash and roll around a glob of PLA. Raised the nozzle and, obviously, adhesion got worse. Tried several dozen prints and could never get past the skirt without issues. About half the time, the PLA would adhere to the side of the nozzle and drag a portion of the skirt off course. I also compared the nozzle diameter with one of the 0.6mm nozzles that came in a multi pack of generic brass nozzles and the diameter on the micro swiss was much larger. Compared to the 0.8mm in the same generic brass nozzle assortment and it seemed much closer to the 0.8mm. I really dont understand all the positive reviews, maybe I just got 1 in a million with terrible QC. But I definitely would avoid this nozzle.

Changed the hotend on my 3D printer and purchased .2, .4, .6 and .8

So I had the unfortunate opportunity to break my beloved M-S nozzle (my mistake, tried to remove it while cold after a PETG print and sheared it off) and because I was in a time crunch, replaced it and the heat block with a cheap backup I had lying around. The difference is night and day. I had nothing but globs and print failures until I bit the bullet and ponied up the $25 to get a new M-S nozzle and heat block. Problems entirely solved! Printing PETG and PLA like a champ again on my Ender-5 with M-S direct extrusion. I also use the 0.8mm nozzle from M-S for TPU in this setup, and it works flawlessly. (side note - I also got the Sunlu filament dryer and it solved my PETG stringing issues. It makes a great companion to this excellent nozzle system) Micro-Swisss sticker has earned its place on my tool cart!

A nice nozzel that will last quite awhile with regular filament and will hold its own with abrasive filament. No brainer to install, slightly larger than a standard brass, use appropriate wrench.

Excellent for PETG filament as it does not stick anywhere near as much as the brass nozzles.

Im not sure if I just never got the temperature right or what but this nozzle gave me nothing but endless clogs. Prints were always inconsistent. I tried 4 different brands of filament and ran temp towers on all of them. I could never get consistently from one print to the next. It really seemed like filament just stuck to the nozzle.

The quality of the nozzle and the quality of print is at the top. I am giving it 3 stars because this nozzle cannot print effectively unless at very slow speeds. I can only run at 20mm/s with it vs the brass nozzle it replaced. I was running 50mm/s on the original nozzle that came with printer. Going over 20mm/s will cause the extruder to eat through the filament because the nozzle cannot heat the plastic fast enough.. I can bump the speed to 25mm/s if I bump the temp to something like 20 degrees above the recommended for the filament but I am uncomfortable with that so I will not be using that as a way around this. Taking the nozzle off and inspecting it shows there are no clogs. Inspection also included that of the Heater block, break and heatsink. Extruder is clean with no visible signs of clogging or wear.

This nozzle replaced a standard brass nozzle on a CR-10S. I put it through the paces with several wood filament prints as well as PLA, ABS and HIPS and have so far not noticed any deterioration. I already ran my nozzle 10 - 20 degrees hotter than most recommended filament temperatures and did not need to make any adjustments to my print temperatures with this nozzle.

Worked great printing 14-4 stainless steel on an ender 3 pro
