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

If you print anything thats abrasive like glow in the dark or wood then this is a must. I havent had an issue since switching from brass. Only change I made was I raised my print temp by about 5 degrees.

I bought this after reading some reviews i wanted a nozzle for future prints with abrasive filament but it didnt even make it to that! Originally i received what appeared to be a used/returned nozzle, no big deal i contacted the seller and they promptly sent me a new replacement. So when i set up the first print with PLA, filament instantly started to just curl out onto the nozzle and clogging. I tried cleaning it, switching filament, adjusting temperatures but nothing. Opening of the nozzle seems to not be fully circular , not drilled out properly.

Was going to use to print carbon fiber filament but this item was shipped with other items and pretty sure it got thrown away because you can’t see it that’s how small it is. Ordered another one and almost lost that one until I ripped the box down!

Didn’t fit the CR10S-Pro at all

This thing just caused all sorts of problems for me. There’s something about the plating that just loves to hold onto filament. Inside and out. I’ve never had issues with clogging til I switched to this and it would clog constantly. Save yourself the trouble.

It greatly reduced print time when detail is not needed. I dont know about the abrasive resistance.

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.

It seems to clean up easier than the OEM brass nozzle. Smooth printing and good print quality. Expensive, but it does improve things. Im sure others work just as well, but this is a good choice.

Must

It is a quality nozzle. I havent run anything abrasive through it to know if it would last longer then a none hardened nozzle. The 8mm tip is great for prints that dont have a bunch of small details, cuts the time to print in half.
