Creality K1/K1C/K1 SE/K1 Max Hotend Kit, Official Upgrade Ceramic Heating Block Kit, Terminal Without Buckle New Version, Unicorn Quick Swap Nozzle, High Flow Heat for Creality K1 Series 3D Printers

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

Used to have slow heating and heat creep causing clogs and lots of frustration! Months later with this hot end, no clogs, heats super fast, and prints fantastic! Outside of updating to klipper, this is my favorite upgrade and well worth the money!

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.

works good

My K1 is a later model that already has the red cover hot end, it printed well but the nozzle was ready for replacement. When searching for a new nozzle I saw this kit which included the new unicorn nozzle for not much more cost than a replacement nozzle. Bit the bullet and bought this upgrade kit. Install took about 10 minutes, everything fit perfectly. Fired up the machine with a fresh roll of filament. Ran a self test (input shaper and auto level), max flow test, and a very fast temperature test. After about 3 hours of test prints and a couple very minor tweaks my K1 is printing better than it ever has. This new hot end and the new default profiles in the crealitu slicer are so much better than what the K1 shipped with. It's obviously very strongly inspired by the Bambu products but at a fraction of the cost and honesty better part and upgrade availability. Very happy with my K1 and this unicorn hot end.

Works great you have to recalibrate all flow and motion characteristics. Great hot end

Worked okay for 3or4 test prints, but the Teflon tubing formed a clog that melted into a balloon shaped mess and every new Teflon tubing I replaced does it ever since.since

I ordered this Creality hotend upgrade kit expecting the newer 2025 version with the updated K1C adapter clips, but what I received is clearly the older version shown in the listing photos. The main difference is the cap/clip design. The included clip did not properly fit the heater wire base, so I had to very carefully remove the heater wire from its base to make it work. After some gentle adjustment, I was able to install the heat wire clip and get everything running—so functionally it works, and my machine is back up and printing fine. That said, the listing is misleading. It should clearly state that this is the older version and does not include the updated K1C adapter clips introduced in newer models. Buyers expecting a drop-in upgrade for the latest K1C setup may run into the same issue I did. Overall: workable product, but be prepared for some modification if you’re expecting the newer clip design. Clearer product description would make this a much better buying experience.

Much better than the stock one. Haven’t had one issue with this in fact the original head clogged all the time. A great improvement over stock.

The part did not work. We are still trying to get the machine fixed

the upgrade kit was easy to install and is working better than I had expected. It is a plus for me as it has extended the life of my printer and the results are excellent. Good value.

Funciona de maravilla

No sirve para la K1 Max está un poco más chico lo que hace que la boquilla obstruya el cortador de filamento del extrusor.
