Official Creality Ender 3 V3 SE KE Upgrade Hotend Kit, 3D Printer Ceramic Heating Block with Quick-swap Nozzle Kit, Supports 300°C High Temperature, 600mm/s High-Speed Printing

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.

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!

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

i usually dont give out reviews but i had to this time. what is this nonsense. They sent the wrong wire size which ruined the port for the attachment for the hotend. It has been a atrocious experience using the printer and its attachments ever since i got it. WASTE OF MONEY.

Great upgrade for ender 3v3se

​Why did you pick this product vs others?:​ I have been waiting to see how this nozzle system would be adopted, as there have been so many systems over the years that go nowhere. After seeing other manufacturers adopting the same nozzle system I decided to try this upgrade. Clogs and extruder issues are extremely difficult to clear when using the original K1 Max hotend system, which uses Volcano nozzles. With this Unicorn system, clogs and extruder issues are very easy to clear. PLUS, I can swap nozzles in seconds now. ​Fit:​ The new parts fit really well, though you may have trouble removing the original components. Creality used a HUGE amount of hot glue to glue in connectors, making the removal extremely difficult. Try using isopropyl alcohol to remove the glue. It may take a bit of time to do this, but it will prevent you from destroying the PCB while trying to remove the connectors. ​Value for money:​ Just like the original extruder had to be replaced, which Creality provided free of charge, the original hotends also need to be replaced. However, I had to pay $137.92 in total to upgrade both of my K1 Max printers to this new system, which includes replacing the replacement nozzles. Fixing manufacturing defects should be free, as I have been dealing with these issues for 2 years. If you need to repair an existing Unicorn system due to some failure or accident, I think the price point is good. I did find that 1 claim in the description is false. There is absolutely no difference in the maximum flow rate of this Unicorn system and the original Volcano system. I had a maximum volumetric flow rate of 22cm^3/s before, and a test after the installation I have a maximum volumetric flow rate of 22cm^3/s now. No difference at all. What I did gain is the ability to clear issues much faster, and easier, while also being able to hot-swap nozzles in less than 30 seconds. These plusses are more than enough reason to upgrade, but I did remove 1 star for the false claim of the maximum volumetric extrusion increasing to 32cm^3/s. BEST

Works as intended, easy to swap for my Ender V3 KE.

Perfecto repuesto para la crealyti ender 3 v3 se

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.
