Creality Official K1/K1 Max/K1C Hotend Upgrades Kit, K1 Series Ceramic Heating Block Kit, 3D Printers Hotend with Integrated Quick-Swap Nozzle, Supports 300°C High Temperature, 600mm/s High-Speed

No sirve para la K1 Max está un poco más chico lo que hace que la boquilla obstruya el cortador de filamento del extrusor.

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!!

​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

Pretty decent hot end for a good price. The extended tube is nice for filament to run through. Worked great when trying to print single color prints. Bought a CFS for multicolor but had no luck. But I would recommend for single color prints!
