The Creality K2 Pro and Prusa Research MK4S are cross-brand rivals: both are prosumer-tier printers, listed $130 apart. The MK4S costs $130 more and gets you an open-source design and extra engineering materials (PC); the K2 Pro answers with 134% more build volume and an enclosed chamber (with PA-CF on its materials list).
Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Makers who need an enclosed printer capable of engineering filaments (PA, ABS, ASA) with optional multicolor, and want more build volume than the K2 or the Bambu X2D.
Full details →Late in cycle — but an upgrade kit is available. Existing owners can upgrade without buying new
🔧 Upgrade kit available — from MK4, MK3.5
Best for: Makers who value open-source hardware, community support, long-term repairability, and battle-tested reliability over raw speed or multicolor features.

The K2 Pro was released on Aug 25, 2025, 444 days ago. Its previous release cycle ran about 548 days, so it is 81% of the way through — roughly 104 days before a successor would be due at that pace.
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 K2 Pro is late in its cycle (81% through).
Cycle and deal status as of November 12, 2026. See the launch calendar →
The K2 Pro lists at $599 and the MK4S at $729 — $130 apart, so the MK4S costs 22% more.
Per litre of build volume, that works out to $22 for the K2 Pro versus $63 for the MK4S — the K2 Pro is both cheaper and roomier, so it wins on value outright.
Our pick for most buyers is the K2 Pro, for a lower price ($130 less) and 134% more build volume. Go for the MK4S instead if you want an open-source printer you can modify and repair yourself — the K2 Pro is not open source. One caveat: the K2 Pro is late in its cycle (81% through), so check the launch calendar before you buy.
How we judge timing and deals: read our methodology →
Unlike most budget enclosed printers that passively trap heat, the K2 Pro actively heats the chamber to 60°C — critical for reliable ABS, ASA, and PA-CF layer adhesion.
The K2 Pro's cubic build volume gives you nearly 60% more printable space than the Bambu X2D (256×256×260 mm) — ideal for large functional parts and prototypes.
The Combo version includes Creality's CFS (Creality Filament System) for 4-color filament switching. Works across the Creality K-series lineup.
MK4 and MK3.5 owners can upgrade to MK4S specs without purchasing a whole new printer. This is Prusa's commitment to owners and is unique in the industry at this level.
Firmware, PCB schematics, hardware designs, and slicing profiles are all published under open licenses. You own the printer completely.
Prusa's forum, knowledge base, and repair guides are unmatched. Parts are stocked and available for years after purchase.
