The Creality K1C and Prusa Research MK4S are cross-brand rivals: both are prosumer-tier printers, listed $230 apart. Note that the K1C has been replaced by the K2 and is no longer sold new. The MK4S costs $230 more and gets you extra engineering materials (PA and PC) and an open-source design; the K1C answers with an enclosed chamber (with PA-CF on its materials list) and 4-slot multicolor.
This printer is no longer sold new. It has been replaced by the Creality K2.
Best for: Makers who need enclosed CoreXY printing for PA-CF and ASA on a budget — and want a capable alternative to Bambu without the ecosystem lock-in.

The K1C has been replaced by the K2 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
The MK4S was released on Aug 13, 2024, 821 days ago. Its previous release cycle ran about 730 days; it is now 91 days past that point and no successor has been announced.
On timing alone, the MK4S is the safer buy right now — it is 91 days past its ~730-day cycle with no successor announced, while the K1C has already been replaced by the K2.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The K1C lists at $499 and the MK4S at $729 — $230 apart, so the MK4S costs 46% more.
Per litre of build volume, that works out to $41 for the K1C versus $63 for the MK4S — the K1C is the better value per litre as well.
Buy the MK4S. The K1C has already been replaced by the K2 and is no longer sold new, so it is only worth considering at a clearance price. If the K1C appealed to you, the fair comparison today is the MK4S against the K2.

How we judge timing and deals: read our methodology →
The K1C ships with a hardened steel nozzle rated for carbon-fiber filaments — a significant cost advantage over printers that require aftermarket nozzle upgrades.
Few printers under $500 offer genuine enclosure capability. The K1C delivers ABS and ASA-capable chamber temperatures.
Matches the Bambu P2S's 600 mm/s top speed for about $50 less.
