The Bambu Lab X1C (professional) and Qidi Tech Plus4 (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 both have been replaced — the X1C by the X2D and the Plus4 by the Plus5 — and neither is sold new. Both are enclosed CoreXY printers with 4-slot multicolor and automatic calibration. The X1C costs $500 more, without a hardware advantage on the specs we track; the Plus4 answers with 55% more build volume 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 It has been replaced by the Bambu Lab X2D.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.

Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale. Look for clearance deals — the Plus5 is the current model.

The X1C has been replaced by the X2D and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
Neither printer is sold new any more: the X1C has already been replaced by the X2D and the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Plus4 lists at $699 and the X1C at $1,199 — $500 apart, so the X1C costs 72% more.
Per litre of build volume, that works out to $71 for the X1C versus $27 for the Plus4 — the Plus4 is both cheaper and roomier, so it wins on value outright.
Neither is sold new any more, so we would not buy either at full price: the X1C has already been replaced by the X2D and the Plus4 has already been replaced by the Plus5. The fair comparison today is between their replacements.

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.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
