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

Great for printing bigger items

Tried this nozzle on the Creality Ender-5 with the Micro-Swiss All Metal Hotend. The hot-end printed the parts, but this nozzle caused tiny hairs to be pulled across the part when the hot-end moved. Adjusted all sorts of retraction settings, but couldnt get past the tiny hairs. This wasnt too big of an issue as I could hit it with a hot air gun that I use with heat shrink and clean them off. The real problem came in with bed adhesion. Using this nozzle, the PLA+ would not adhere to the bed through the entire print and caused warning. I replaced it back to the standard nozzle, using the same gcode, same temperatures, same material, same bed surface and my PLA+ had no issues with adhering to the bed. In the pictures, the part on the left is printed with the standard nozzle and the part on the right is the Micro Swiss MK8 Plated A2 Tool Steel Wear Resistant Nozzle. Same gcode used for both prints. You can see the adhesion problem with this nozzle and PLA+ Whatever they used to coat this nozzle for wear resistance, drastically affects the materials.

I don’t understand how people are having problems with this nozzle. I will say that 99% of negative reviews on here are due to user error. I installed on stock Ender 3 hotend to print Carbon Fiber PLA. Installed the nozzle correctly, upped the temp in Cura about 5c (print a temp test tower to find your temp) and started printing. Been through at least 4kg of CF/PLA and 8kg+ of PLA and PETG without any clogs or other problems. The nozzle still looks great, stays clean, and prints beautifully.

I am on my second one of these nozzles. I dont think that the first one had to be replaced but I was doing some maintenance so I changed it. The first one lasted me at least 6 months with hundreds of hours of printing with no problems. They are a little pricey compared to regular brass nozzles but youre limited to what you can use with the micro Swiss hot ends. At least they last a while.

Ive got Microswiss nozzles on all my printers, they last forever even with abrasive materials and print beautifully. Highly recommended.

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.

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.

Works great on the Monoprice Ultimate 2 So first of... many review complaints state they have to increase the temperture settings to get good print... and that their old temperature settings worked great with cheap brass nozzles so why dont they work with this expensive nozzle... then they give this nozzle a bad rating. It PHYSICS! Brass conducts heat much faster than steel. The temperature sensor is in the heating block, not the tip. So the system doesnt know you changed to steel tip that does not conduct heat as fast as brass. As a result you will need to run tests with your favorite filaments to figure out what the best temperature setting is for the steel nozzle. Once you take the time to figure out the new temperture, it works great and last A LOT longer than the cheap brass nozzles. Its your choice, take the time to figure out settings for a nozzle that will last a long time, or keep buying cheap brass nozzles and throwing them away.

⚠️ WARNING!!!!! THIS DOES NOT FIT THE MICRO SWISS ALL METAL HOT END. I BOUGHT THIS TO REPLACE THE STOCK .4MM NOZZLE THAT CAME WITH MY MICRO SWISS HOTENED BECAUSE IT HAD FINNALY GIVEN OUT ON ME. NOT THE SAME LENGTH THREADS. WILL NOR FIT.

My general PLA/PETG temps wouldnt work well after replacing. Had to turn the heat and the nozzle up by about 10 degrees first week or so to get ok prints. After the first week, I was able to go back to the standard settings. Super strange and not documented.
