The Bambu Lab X2D (professional) and Prusa Research CORE One+ (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. Both are enclosed CoreXY printers with automatic calibration. The CORE One+ costs $350 more and gets you an open-source design and 8 multicolor slots to the X2D's 4; the X2D answers with a top speed of 1,000 mm/s (vs 600) and 15% more build volume.
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.

🔧 Upgrade kit available — from CORE One+, MK4S
Best for: Makers who want CoreXY speed and precision with Prusa's open-source ethos, community support, and long-term repairability — without Bambu's closed ecosystem.

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 CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through — roughly 118 days before a successor would be due at that pace.
Both are early enough in their cycles that timing should not decide this one. The X2D has roughly 1,147 days of runway on past cadence and the CORE One+ has roughly 118 days of runway on past cadence. Pick on features and price.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The X2D lists at $649 and the CORE One+ at $999 — $350 apart, so the CORE One+ costs 54% more.
Per litre of build volume, that works out to $38 for the X2D versus $67 for the CORE One+ — 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 lower price ($350 less) and a top speed of 1,000 mm/s (vs 600). Go for the CORE One+ 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.
The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source — firmware, hardware, slicing profiles.
Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.
The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
