The Bambu Lab X1C (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. Note that the X1C has been replaced by the X2D and is no longer sold new. Both are enclosed CoreXY printers with automatic calibration. The X1C costs $200 more and gets you extra engineering materials (PA-CF) and 13% more build volume; the CORE One+ answers with an open-source design and a top speed of 600 mm/s (vs 500).
This printer is no longer sold new. It has been replaced by the Bambu Lab X2D.
Best for: Professional makers seeking the X1C should now consider the X2D (its direct successor) or P2S (prosumer enclosed). Clearance X1C units offer the LiDAR and AI monitoring features at a reduced price.

The X1C has been replaced by the X2D and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.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 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.
On timing alone, the CORE One+ is the safer buy right now — it is only 44% of the way through its expected cycle, while the X1C has already been replaced by the X2D.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The CORE One+ lists at $999 and the X1C at $1,199 — $200 apart, so the X1C costs 20% more.
Per litre of build volume, that works out to $71 for the X1C versus $67 for the CORE One+ — the CORE One+ is the better value per litre as well.
Buy the CORE One+. The X1C has already been replaced by the X2D and is no longer sold new, so it is only worth considering at a clearance price. If the X1C appealed to you, the fair comparison today is the CORE One+ against the X2D.

How we judge timing and deals: read our methodology →
The X1C's LiDAR sensor maps bed surface deviation and adjusts in real time — the most reliable first-layer consistency in its class.
The built-in camera with spaghetti detection pauses prints automatically when failures are detected — critical for unattended production runs.
The X1C uses a die-cast metal frame and carbon-fiber-reinforced structure for rigidity at high speeds.
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.
