Official Creality K1/K1 Max/K1C Hotend Upgrades Kit, Unicorn K1 Series Ceramic Heating Block, 3D Printers Hotend Integrated Quick-Swap Nozzle, Supports 300°C High Temperature, 600mm/s High-Speed

This is a great upgrade from the stock hotend it’s build quality and fit and finish is great, went on very easily and works well, heats up significantly faster and has stable temperatures compared to the stock hotend while the stock one is completely fine it’s worth the money if you print often or print at higher temps because the nozzle pushes the teflon tube higher up away from the heating element so the teflon doesn’t deteriorate and cause clogs or release toxic fumes, print quality honestly seems about the same as stock but mainly bought for the teflon issue and the faster heating.

I was having trouble with my extruder skipping and getting very poor print quality. I replaced the extruder stepper motor and extruder, thinking that was the problem since my printer showed that my hot end was getting up to temp. After nothing worked, I figured I would replace the hot end since it was the original hot end from when I bought the printer 2 years ago. WOW! What a difference this hit end has made. Now I get better prints then when my printer was new!. About the product. It is an upgrade hotend for the Ender 3 V3SE and KE. It uses the unicorn nozzles, so don't try using the sprite nozzles, they won't work. The new hotend was an easy installation by just removing the shroud and extruder, the removing the 4 screws holding the fan. The new hot end attaches perfectly to where the original hot end mounted. The electrical connections fit precisely as it was the original hotend. It took me about 10 minutes to take off and replace. I ran the leveling program and then did a level test print. The test came out almost perfect. I did raise the Z offset up by 1. This hotend upgrade is producing fantastic prints. This has solved my extruder skipping problem. Sometimes I just get to tunneled vision and didn't realize how much I had printed with the original hotend and they do wear out after awhile. I am very happy with this hotend upgrade and recommend it to those of you who own an Ender 3 V3 SE or KE.

Very easy and cost effective way to get a normally very expensive upgrade for other printers, comparable to E3D Revo Obxidian nozzles. I'm really impressed with the various upgrade paths for the KE. Works perfectly and opens up opportunities for using advanced filaments like ABS-GF and PETG-CF. Without a heated chamber you probably won't get away with PA-CF...

Doesn't fit k1c, wrong wiring harness. Completely useless. Completely unable to contact tech support as they don't offer this type of problem as an issue that they resolve

I have had this for a few months now , the heat this can handle is great . Fits perfectly in place of the one I had to pull off . I have had some clogging with them but I would think that’s expected every now and then . For the price , I would say I get my moneys worth with all the printing I have done since swapping to this setup .

Quality is good. But this is the second one I’ve had to replace. AI mistake print watcher doesn’t seem to be working. Plastic occasionally backs up like crazy necessitating babysitting of the unit or replacement of this part more often than I’d like.

Please note, this upgrade does not use the standard OEM nozzles, but the Unicorn Quick swap nozzles. They use hardened steel, titanium, and copper on the nozzle with the upgraded heater really did help with the prints and I was able to bump the speed up on some prints. It really does heat up faster and seems easier to maintain temperature. I will be printing ASA CF and ABS, along with PLA CF and PETG, so I like the fact that this nozzle is ready for all of those materials without needing to swap nozzles out. Another benefit is that you don't have to worry about the nozzle being perpendicular to the bed like with the OEM one that needs adjust straight out of the box with the two alignment/securing screws. IMO, well worth the price and easy to swap out if you follow the instructions

Works well.
