CrealityOfficial 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.

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...

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.

My K1 clogged up and had a massive build up of leaked out filament from the hotend which ruined my extruder and the hotend. I struggled to remove the old one but once I got that out I got this screwed in and up and running in a few minutes so the installation was easy.printed good so far!

Very durable hot end, improved my print quality in my v3se. The value for what you get is insane. It’s very easy to install and fit perfectly. Hasn’t clogged yet in a couple Months of use.

​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

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

A lot easier to swap out than expected. Had a blob of death and decided to replace hot end. Glad I chose the one with heat fins
