Two enclosed CoreXY printers, about $100 apart, sold to the same person. The single real difference: the P1S is the cheapest enclosed door into Bambu's multi-color ecosystem, and the K1C is built to chew through abrasive carbon-fiber filament without wearing itself out. Everything else between them is close enough to be a preference.
Start with what cancels. Both enclose the chamber, so ABS and ASA stop lifting at the corners. Both run hotends rated to 300°C. Both are quoted at speeds — 500 mm/s for the P1S, 600 mm/s for the K1C — that neither holds for long on a real part, since acceleration limits and cooling decide print time far more than the top number does. Both are loud enough that you will not want one in a bedroom.
The Bambu Lab P1S
At $550–700 the P1S is the value machine among Bambu's enclosed printers: the X1 Carbon's motion system and enclosure without the lidar, the touchscreen, or the premium price. Build volume is 256 x 256 x 256 mm, meaningfully more room than the K1C in every direction. Out of the box it is closer to an appliance than a project — auto bed leveling, vibration compensation, and profiles that mostly just work.
The reason people buy it, though, is the AMS. Bolt on the four-spool unit and you get genuine multi-color and multi-material printing, plus automatic spool switching when one runs out. That capability is also the recurring cost: every color change purges filament into a waste tower, and on a colorful model the purge can rival the part in weight. The AMS itself is a significant add-on purchase, not pocket change — and if multi-color is the only thing you want, Bambu's cheaper open-frame A1 line bundled with AMS Lite gets you there for less, just without the enclosure.
The other honest drawbacks: the ecosystem is more closed than Creality's, firmware and cloud policy are Bambu's to change, and the stock nozzle is stainless steel, which abrasive filament erodes. A hardened nozzle is a cheap swap, but it is a swap you have to make.

The Creality K1C
At $450–560 the K1C is the cheaper machine, and it spends its budget differently. Build volume is 220 x 220 x 250 mm — smaller, though large enough for the overwhelming majority of prints. The headline is the hardened extrusion path: a hardened steel nozzle and a direct-drive extruder specified for carbon-fiber and glass-filled blends, with a filament path meant to keep brittle CF from snapping on its way in. On the P1S, printing CF is something you prepare for. On the K1C it is the default configuration.
It also runs Klipper-based firmware, which matters if you like control. Input shaping, pressure advance, and macros are yours to tune, and the machine is far friendlier to third-party slicers and mods than a Bambu is.
The cost of that openness is work. Stock profiles are serviceable rather than excellent, and best-case surface quality means tuning rather than pressing print. Stock fans are loud. The K1C has no first-party multi-material unit, so multi-color is not a feature you can add later. And Creality's speed-printer community is smaller and less settled than the enormous Ender ecosystem the brand is known for, so answers at 11pm are harder to find.

How to choose
Want multi-color prints in an enclosed machine, or want to leave that door open? Buy the P1S. There is no path from the K1C to four-color printing, and adding an AMS later is a purchase, not a rebuild.
Printing functional parts in CF-nylon, CF-PETG, or glass-filled blends? Buy the K1C. Buying abrasion resistance as a factory default is cheaper and less fiddly than upgrading a P1S nozzle and accepting that its other wear parts were never specified for the job.
Two tiebreakers. If you want a machine that behaves like an appliance and you would rather spend evenings designing than tuning, the P1S wins on setup polish alone. If you resent closed ecosystems on principle and enjoy Klipper, the K1C is the only one of the two that will ever be fully yours.
Skip both if
You only print PLA and PETG decorative pieces. An enclosure and a 300°C hotend are solving problems you do not have, and a good open-frame printer costs half as much. Skip both, too, if the parts you need are genuinely large — both build volumes sit in the same modest class, and neither one fixes that.
Bottom line
Same category, opposite bets. The P1S costs about $100 more, prints in a bigger box, and buys you into color and a system that mostly manages itself. The K1C costs less, arrives ready for abrasive engineering filament, and hands you the firmware keys in exchange for tuning time. Color and convenience: P1S. Carbon fiber and control: K1C. The wrong answer is buying either one for the specialty you will never use.
