The Creality K2 Plus (professional) and Prusa Research MK4S (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. The K2 Plus costs $470 more and gets you 271% more build volume and an enclosed chamber (with PA-CF on its materials list); the MK4S answers with an open-source design and extra engineering materials (PC).
Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Professionals and studios who need large-format enclosed multicolor printing without the premium price of Bambu's or Prusa's flagship offerings.
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.

Cycle and deal status as of November 12, 2026. See the launch calendar →
The MK4S lists at $729 and the K2 Plus at $1,199 — $470 apart, so the K2 Plus costs 64% more.
Per litre of build volume, that works out to $28 for the K2 Plus versus $63 for the MK4S — so the pricier K2 Plus actually gives you more build space per dollar.
If you are buying before Dec 5, 2026, the active sale tips value toward the K2 Plus.
Our pick for most buyers is the MK4S, for a lower price ($470 less) and an open-source design, plus a higher editor score (8.9 vs 8.3) and better buy-now timing. Go for the K2 Plus instead if you print large parts — its 350 × 350 × 350 mm build volume holds 271% more than the MK4S's 250 × 210 × 220 mm.
