The Bambu Lab X2D (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 MK4S costs $80 more and gets you an open-source design; the X2D answers with a top speed of 1,000 mm/s (vs 500) and an enclosed chamber (with PA-CF on its materials list).
Just released — full support runway ahead
Best for: Professional makers who want the X1C's footprint with true dual-material capability, an active heated chamber for engineering filaments, and improved filtration — without stepping up to the larger, pricier H2 series.
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 X2D was released on Apr 14, 2026, 212 days ago. Its previous release cycle ran about 1,359 days, so it is 16% of the way through — roughly 1,147 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 X2D is the safer buy right now — it is only 16% of the way through its expected cycle, while the MK4S is 91 days past its ~730-day cycle with no successor announced.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The X2D lists at $649 and the MK4S at $729 — $80 apart, so the MK4S costs 12% more.
Per litre of build volume, that works out to $38 for the X2D versus $63 for the MK4S — the X2D is both cheaper and roomier, so it wins on value outright.
If you are buying before Dec 5, 2026, the active sale tips value toward the X2D.
Our pick for most buyers is the X2D, for a top speed of 1,000 mm/s (vs 500) and an enclosed chamber (with PA-CF on its materials list), plus a higher editor score (9.1 vs 8.9) and better buy-now timing. Go for the MK4S instead if you want an open-source printer you can modify and repair yourself — the X2D is not open source. The X2D is also in a sale window right now (Bambu Black Friday 2026, until Dec 5, 2026).
How we judge timing and deals: read our methodology →
A second Bowden-fed nozzle enables two-material prints and soluble supports without a purge tower, in the same compact 256 mm class as the X1C it replaces.
Unlike the X1C's passive chamber warming, the X2D actively heats to 65°C — enough for the bulk of engineering filaments including ABS, ASA, and nylon.
Improved filtration and a toolhead-mounted camera add safety and monitoring over the X1C's chamber camera.
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.
