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

I got this to do some 3D projects for a friend that wanted to have the parts in wood PLA. It worked grate and was easily calibrated with my Ender 5 Plus set up.

I got it to work, and it work with about a half dozen prints. The fastest I could get the nozzle to work was 20mm/s at 260C using PETG, and the same speed at 240C using PLA. Up until this point I was using the cheap brass ones from china (the kind you can buy in a 30 pack for $10). They printed at 230C and 60mm/s for PETG, but needed to be replaced monthly. I desperately wanted this nozzle to be my forever nozzle. The one that I would put in and never need to replace again. Sadly this is not the case. I gave it 2 stars because it does work, its just energy and time inefficient. And after 2 saturdays of playing around with this, Im done. Im going back to the cheap ones and Ill try to recycle them so I dont feel so bad about the waste.

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.

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.

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.

Came as expected, works great! No issues no clogs. Clean print. Very happy!

Other than the price, you cannot beat Microswiss products. Their nozzles are great and last a very long time. But nozzle tech is catching up and is generally pretty good across the board as long as you match your wear coefficient with your filaments to get good life from them. Would be 5 stars except for the price. Ive started looking around more for alternatives at better prices and have found several.

7mm wrench for this guy. Stock mk8 on my creality was 6mm. This nozzle seems to have slightly slower ramp times for heating. Guess and check and it should work fine. I installed mine to spec, heated to 240, then torqued a second time to get it set in place before cooling and calibrating the rest as usual.

I used this on my Micro Swiss hot end installed on my Ender 5. I printed several multi hour prints without issue and no clogs. I also picked up their .04 nozzle as well. Great parts!

I thought the stock Ender 3 v2 was great on its own but these somehow made the PLA lines even nicer without any adjustment. Not sure how but Ill take it!
