Yes, a Creality K1C (often nicknamed "Cap" in some communities because of its speed or just as a fun shorthand) can 3D print carbon-fiber reinforced filaments very well — in fact, it’s one of the best stock budget printers for doing so.

Here’s why the K1C is particularly good for “cap” (carbon-fiber filled) materials:

a.Fully enclosed chamber (helps with ABS, ASA, and carbon-fiber variants that can warp or release fumes)  

b.All-metal “unicorn” direct-drive extruder with hardened steel nozzle (stock nozzle can handle carbon-fiber PLA, PETG-CF, PA-CF, etc. without wearing out quickly)  

c.300 °C hotend capability (needed for nylon-carbon fiber and some PC-CF filaments)  

d.Good active carbon filter in the chamber (reduces fumes from abrasive or stinky filaments)

People regularly print these on the K1C with great results (no upgrades usually needed):

PLA-CF (e.g., Bambu Lab, Polymaker, Elegoo)  

PETG-CF  

ABS-CF  

PA6-CF / PA12-CF (nylon-carbon)  

PC-CF (polycarbonate-carbon)
