Micro Swiss All Metal Hotend Kit for Creality CR-10 / CR10S / CR20 / Ender 2, 3, 5 Printers

This was the last thing I was going to try to get my CR-10s working properly again after trying to get rid of heat creep that kept melting the filament far too early and clogging the nozzle. It was a vast improvement and was finally solved by directing the air flow from the cooling fan directly over the fins. The all metal construction makes installation much easier. The PTFE tube only needs to be inserted into the top section of the assembly meaning it never comes into contact with any heated areas of the hot end - tube lasts longer without having to be replaced as often due to accumulated heat damage. It was so successful I ordered one for my Ender 6 as well simply because it is a design I trust. Couple it with the Solex nozzles also sold at Spool 3D to get a winning combo that makes printing much more reliable.

Nice kit, far better quality than the OE hotend that came with the printer. Simple install, no issues. My PETG filament is running much smoother now, no blockages so far and consistant extrusion.

Well built hot end. Titanium heat break does a good job keeping the heat localized at the hot end. No clogging or retractions issues. I have tuned my end gcode to retract more filament then what comes stock in most slicing software.

I really love it, prints incredibly well!!

works for about 3 months, then due to heat expansion and contraction, it starts to clog. Becomes useless quickly and makes messes not prints. I would not recommend nor will I ever buy this item again. I have gone back to the Creality hotend and it is working like a dream again.

I love it, had to make adjustments to my prints, but other than that, no regrets

The product works as expected. The user is required to have prior knowledge to be able to use this item to its full potential. Great product. 5 stars. #wouldbuyitagain.

since I started using this hotbed my prints just look better than before. Easy installation. Very happy

The hotend works well, but it's not with out it's quirks. First of all, it has issue maintaining temperatures over 225c or so, which isn't a deal breaker since I use PLA mostly. I've yet to try a different heater cartridge or upping the supply voltage, so that may help it. Second, it has a super defined and well working heatbreak, which can be a problem when changing filaments since you need to extrude just a little then pull it out quickly. Again, this is a bit of a non issue because you can write a g-code file for this. I'm still going to give this three stars though, since honestly it's a well made product and it hasn't jammed at all compared to the stock hotend.
