X1 Carbon
DiscontinuedThe printer that put Bambu on the map. Lidar first-layer scanning, AI spaghetti detection, full enclosure: the X1C delivered the best quality Bambu could produce at the 300°C tier. Discontinued March 2026, its successor is the X2D ($649), which adds a dual nozzle and active chamber for far less money.

Bambu ended the X1 Carbon (and the whole X1 series) on 31 March 2026. It is no longer sold new. The successor is the X2D ($649), which adds a dual nozzle and active 65°C chamber for far less than the X1C cost.
Should I buy the X1 Carbon?
The X1 Carbon is discontinued. If you specifically want Lidar-based quality sensing, look for a used unit. For a new machine, the X2D ($649) is the direct successor and beats it on most specs; the P2S ($549) is sufficient for most printing, and the H2S ($1,199) gets you a larger volume and active chamber.

Known issues
- Discontinued March 31, 2026: Bambu promises firmware bug fixes and feature updates until May 31, 2027, security patches until May 31, 2029 and spare parts until March 31, 2031. (Bambu blog)
- Bambu Studio keeps the print height at 250 mm and blocks an 18 × 28 mm area in the front left corner for the filament cutter by default; the full 256 mm cube needs a stopper change and works only without the AMS. (Bambu wiki)

The X1 Carbon launched Bambu's reputation and remained capable right up to its discontinuation in March 2026: the Lidar first-layer calibration and AI failure detection were features you didn't find elsewhere in the P-series. At its $1,199 launch price it always sat awkwardly, though: the P2S at $549 produces comparable quality for most prints, and the H2S, which launched at $1,249 in August 2025 and now sells for $1,199, delivers better specs for about the same money (larger volume, faster speed, higher temp, active chamber).
Its differentiator was Lidar-based quality control: genuinely useful for complex multi-layer engineering parts or high-value multi-color models where catching failures early saves material and time. Now that it is discontinued, the X2D ($649) is the direct successor: it drops Lidar but adds a dual nozzle, active 65°C chamber, and a second AI camera for $550 less than the X1C's $1,199 launch price. Buy a new X1C only if you find one at a genuine clearance price and specifically want its Lidar.
Pros
- Lidar first-layer calibration: best in class
- AI spaghetti/failure detection
- Fully sealed enclosure with activated carbon
- AMS up to 16 colors
- Camera and remote monitoring included
- Proven, long-standing platform with excellent support
- Best Bambu print quality at the 300°C tier
Cons
- Discontinued March 2026. No longer sold new
- Successor X2D ($649) beats it on most specs for less
- $1,199 list price was hard to justify vs P2S ($549) for most prints
- H2S ($1,199) has more specs for the X1C's former list price
- 300°C hotend cap (X1E: 320°C, H-series: 350°C)
- Passive chamber only, no active heating
- Same 256mm build volume as much cheaper printers
- AMS sold separately in standalone version
| Material | Support | Notes |
|---|---|---|
| PLA / PLA+ | Excellent | Lidar calibration makes already good PLA prints even better. |
| PETG | Excellent | Lidar catches any first-layer adhesion issues early. |
| ABS / ASA | Excellent | Sealed enclosure with passive heating handles these well. |
| TPU | Supported | Works. Flexible filament handled well by direct drive. |
| PA / PA6-GF | Supported | Bambu rates PA and fiber-filled PA ideal on the X1C. Dry filament essential. |
| CF composites | Supported | Stock nozzle and extruder gears are hardened steel; Bambu rates CF/GF-filled filament ideal. |
| PC | Supported | Bambu rates PC ideal on the X1C. No active chamber heating; the X1E adds it (up to 60°C). |
| PPA-CF / PPA-GF | Compatible | Bambu's filament guide recommends PPA-CF/GF for enclosed printers including the X1 series. Use the hardened nozzle and dry filament. |
| PPS / PPS-CF | Not recommended | Bambu's filament guide clears PPS-CF/GF only for the H2 series and X1E and recommends a 310 to 340°C nozzle, above the X1C's 300°C. Bambu's older X1E comparison page still rates the X1C 'Compatible'. For regular PPS work, an H-series printer is the current option. |
Lidar calibration: Let the X1C run its full first-layer Lidar scan on every print. It adds 2–3 minutes but catches bed offset issues before you waste filament on a failed run.
ABS/ASA: Pre-heat the chamber for 15–20 minutes before starting. Set bed to 100°C and let the sealed enclosure warm up. The passive chamber is effective once pre-heated.
LAN mode: Enable LAN Only + Developer Mode in Settings for Orca Slicer. Connect via local IP and access code.
X1C or P2S? P2S at $549 if you want the best value enclosed printer. The X1C listed at $1,199 ($650 more) and is discontinued, so today it means a used unit; pick one only if Lidar quality sensing and AI failure detection matter to you.
X1C or H2S? The H2S ($1,199 in the Bambu US store) costs the same as the X1C's former $1,199 list price and gets you 1,000 mm/s, 350°C, active 65°C chamber, and a larger build volume. Choose X1C only if you specifically need Lidar quality sensing.
Does Lidar really matter? For most prints: you won't notice. For long, complex prints with fine features: you will. It's insurance more than a daily benefit, but when it catches a failure at layer 1 instead of hour 6, it pays for itself.
AMS with the X1C? Yes, the full AMS (not AMS Lite). Up to 16 colors. AMS is included in some combo packs or sold separately.
