Creality Official Ender 3 V3 SE KE Hotend Upgrades Kit, 3D Printers Ceramic Heating Block with Quick-Swap Nozzle, Supports 300°C High Temperature, 600mm/s High-Speed for Ender 3 V3 SE/Ender 3 V3 KE

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.

Bought this to replace the our broken original one that came with our Ender V3 KE. There is a noticeable difference in quality of the builds with this newer nozzle. I only bought it because the other one broke, but knowing what I know now, I would recommend it as an upgrade. It was relatively easy to install and a great value.

This Official Creality K1/K1 Max/K1C Hotend Upgrades Kit is a masterclass in disappointment. Supposed “quick-swap” turns into a fiddly mess that feels way more fragile than it should, so you’re constantly unthreading and rethreading parts like you’re tuning a vintage radio. The ceramic heating block doesn’t deliver the advertised heat consistency, making prints unreliable and sloppy. “300 °C capable”? More like don’t try it, because it’s sketchy at best and prone to overheating/clogging. The whole kit feels like it was cobbled together with corner-cut parts, and honestly — you’d get better performance upgrading with literally anything else. Skip it and save your sanity (and prints!!

Works great

​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

Excellent hotend, heats up extremely fast, nice clean prints, and easy to swap the nozels .

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
