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

Easy to install and replacement of the old nozzle. My old nozzle got so clogged up that I had to use a Dremel cutting wheel to remove it. This was any easy replacement as it included all the extra pieces like the heat sink that I had to cut through. If you need a replacement, I found this one to be more than suitable but wouldn't have replaced a working nozzle just because this is a new version.

Solved my issues on k1 nax

Do not buy this if you have a newer K1C. They will not fit the K1C. I have seen other K series have this problem. The PCBA tool board that comes with the machine has a different. Upgrading isn’t fun because thecreality 400103014 Is this one that works mit had the clips. Seems like the line who put together the wrong JST male. The thermistor jst connections band they don’t fit. So now to find the correct you will need to find the connection board or you need to find hot tend with claws. I think the line decided to install the wrong connection board. Finding this hot end isn’t easily and finding the correct board is even more challening. They put the wrong jst and it doesn’t fit.

Do yourself a favor, after buying a new K1 Max dump the standard and switch it with this one!

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.

Well, doesn't fit the k1 SE I bought it for to replace a damaged hot end.Everything about it is compatible except for the thermocouple terminal. They used a different style that can't fit into the clip attachment female side on the SEs PCB.But not really the products fault. It's good quality, has all the tools needed and machined well. Very easy to install. If it actually fits.

Pretty good I like it but it's a pain In the butt with the disconnect and connections

Perfect fit and function.
