Creality Official Upgrade Ender 3 V3 KE Hotend Kit with 2 Pack 0.4mm Nozzles, 300°C High Temperature Heating Block, 3D Printer Parts All Metal High Thermal Conductivity Extruder Hot End

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.

Quick and easy replacement, worked perfectly. Got the K1 Max running again.

To be blunt I bought like three of these and all of them burnt out or quite literally fell apart during a print… upon dismantling my assembly I noticed that the small screws the hold the heating elect to the heat sink didn’t even reach the intended position when fully assembled… bought the basic assembly and haven’t had a issue since

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

Easy to install and replacement of the old nozzle. My old nozzle got so clogged up that I had to use a Dremel cutting wheel to remove it. This was any easy replacement as it included all the extra pieces like the heat sink that I had to cut through. If you need a replacement, I found this one to be more than suitable but wouldn't have replaced a working nozzle just because this is a new version.

Well, doesn't fit the k1 SE I bought it for to replace a damaged hot end.Everything about it is compatible except for the thermocouple terminal. They used a different style that can't fit into the clip attachment female side on the SEs PCB.But not really the products fault. It's good quality, has all the tools needed and machined well. Very easy to install. If it actually fits.

Ok I have to say I love this it works great does 300c and has never closed but it does not state it has to have unicorn tips which are much more expensive than normal extruder tips but it prints beautifully and has not clogged and even prints nylon filament great and it does it fast faster than normal tips as unicorn tips are all metal and has larger area for melting so can print and feed faster so if you don't mind paying $12 for 1 tip or I found 3 different a .04+.06+.08 for $19 but it works great I gave 4 because it only says quick swap tips not where other post state requires unicorn tips

Works great I still use it to this day
