K1(Max) Ceramic Heating Block Kit, 2023 Original Heater Sensor for Creality 3D Printer, High Thermal Conductivity, High Flow Printing, and High Temperature Resistance, Exclusively for K1 & K1 Max

Was a perfect fit

I got the K1 & K1 Max Ceramic Heating Block Kit to have a spare for a backup. I have used and changed out plenty of hotends and this one seems to be a direct drop-in replacement. I have not used it yet as I am keeping it for when I need a replacement, but I can tell that it appears to be the same as the original.I would recommend taking your time as the hotend ceramics are round and as another reviewer said, if you do not have a good grip on the original it will spin around, and you can damage the wires. I do recommend the K1 & K1 Max Ceramic Heating Block Kit.

I ordered this and a day after it arrived my current hotend failed on me (Filament cloged the hotend and destroyed the thermistor). This was the perfect fix. It allowed me to quickly get my K1 back up and running in no time!

My big issue with this hot end is that the whole deal is round, meaning that if you want to just change a nozzle, you’d better be real certain you have a hold on the ceramic sleeve part, or you’ll spin the whole unit and rip your thermistor wires, killing the assembly. (Yes, I did that). I’ve heard from others that the nozzle design is kind of an issue as well, particularly if you want high speed printing with generic filament. A potential solution is a CHT nozzle- a nozzle with a three bore kind of interior that help generic filament heat faster and support higher speed flow. You *can* retrofit this hot end with such a nozzle, as the leveling process is based on bed pressure sensors, not the nozzle dimensions, but you may also consider some other third party hot end that has a square body so the spinning isn’t a risk.
