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

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.

Please note, this upgrade does not use the standard OEM nozzles, but the Unicorn Quick swap nozzles. They use hardened steel, titanium, and copper on the nozzle with the upgraded heater really did help with the prints and I was able to bump the speed up on some prints. It really does heat up faster and seems easier to maintain temperature. I will be printing ASA CF and ABS, along with PLA CF and PETG, so I like the fact that this nozzle is ready for all of those materials without needing to swap nozzles out. Another benefit is that you don't have to worry about the nozzle being perpendicular to the bed like with the OEM one that needs adjust straight out of the box with the two alignment/securing screws. IMO, well worth the price and easy to swap out if you follow the instructions

The heat sensing leads just disconnected after 2 prints. There is no way to reconnect them so the printing head is completely useless. I am incredibly disappointed. I wasn’t doing anything out of the ordinary, I just suddenly started getting error readings and found that the head was no longer connected to its leads. Whole assembly is a step in the wrong direction, extremely fragile without improving anything.

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 is my second review. In the first one I said it breaks filament inside and that is true and it's annoying, I can't deny it prints PETG WAY better than my original hotend on my other printer. Far better results for PETG.

It’s was very simple to install and works like a charm!

Let's start with the pros: This genuinely is an easy in/out swap between the old hotend and new one. Good thing too, because if you get a faulty unit (or are really lucky, like me, and got TWO faulty units), you're going to need to disassemble your print head multiple times. If you're printing with a 0.4mm nozzle and never need to change the nozzle, this may even be an upgrade. However, I am using a 0.2mm nozzle and bought this upgrade in hopes of reducing clogging issues - no luck for me on that front. Creality customer support was very quick to reach out when I indicated I had issues, and I am very thankful for that. Now for the cons: This hotend is genuinely awful. The first one I was sent broke almost immediately, the screws holding on the heat block literally fell out of the assembly. I was then sent a replacement directly by Creality. The second one at least didn't have the problem of falling apart for the first few days of print time. However, in the long run I've wasted about a quarter spool of filament just troubleshooting issues. Eventually, one of the wires to the heat sleeve dislodged, which I soldered back in place. The first three times I had to resolder it, I was sure it was something I was doing wrong. Now, the same thing has happened yet again, after a complete failure to print covered the entire nozzle assembly in burnt plastic, and I'm starting to think it is a design flaw or quality assurance issue. This "upgrade" is a side-grade at best. If you really want the K1 style nozzle, maybe it's worth it, but in spite of this being labeled as quick change at the time of purchase, Creality's own instructions tell you to preheat the nozzle before changing it out. There's nothing quick about that change, it's literally the same as the original experience with a V3 unit. I've seen mixed opinions on whether that initial preheat is even required, but considering the fragility of this I will not be risking it and don't recommend anyone reading this review for help try it either. I had really high hopes for this product, but months of troubleshooting with no solution has dulled my enthusiasm for Creality products. Maybe this unit needed to come with an upgraded fan, maybe I truly did receive two faulty units, maybe my 2-year-old printer is just worn out after two solid years of being my one and only workhorse printer, but next time I'm in the market for a printer, it'll probably be an A1.

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.

Works good

Es un producto maravilloso, literalmente plug and play para la Ender 3 V3 KE

Fixed my printer very lovely

Perfect replacement for the original hotend. Original hot end decided that it was a time for a change. Easy to replace, and works like a charm.
