Watch out for
- The K1C's spec table says hardened steel and its FAQ says tri-metal; think of it as a hardened steel tip, not an all-steel nozzle.
- Creality keeps separate wiki pages for the K1C ('Integrated Nozzle Replacement') and the K1 series ('Replace Nozzle'). Follow the one for your model.
- Creality gives no board-revision note with its firmware; match the image to your own mainboard and CFS setup.
What fits
Product details below are the seller's own description unless a source is shown. Pick the variant named for each item.
Hotend
Micro Swiss FlowTech hotend for Creality K1 / K1 Max / K1C / K1 SE (M3101)Choose the FlowTech for K1 / K1 Max / K1C / K1 SE (M3101).
Micro Swiss names the K1C. Its hardware kits differ for older and newer K1-series printers, and newer breakout boards need a separately sold adapter cable.
Replacement heating block
Creality K1 Series ceramic heating block kit (quick-swap nozzle kit)Choose the 'For K1/K1 Max/K1C' style, and match the terminal version (with or without buckle) to your printer.
Creality lists its K1 Series ceramic heating block kit for the K1, K1 Max and K1C, but does not say whether it covers every revision the same way.
Questions
Does the Creality Unicorn nozzle kit fit the K1C?
Yes, Creality lists its Unicorn quick-swap nozzle kit for the K1C, along with the Ender-3 V3 and Ender-3 V3 Plus. See K1 nozzles: integrated vs quick-swap.[2]
Is the K1C nozzle hardened steel?
Creality's spec table says hardened steel, and its FAQ calls it a quick-swap tri-metal nozzle. So the tip is hardened steel; we do not describe the whole nozzle body that way.[1]
Which firmware does Creality list for the K1C?
On 2026-10-08 Creality's support page listed V1.1.0.27, dated Mar 11, 2026. Creality gives no board-revision note, so match the firmware to your own mainboard.[1]
