Product Review

Product Reviewed

Bambu Lab X2D (successor to the discontinued X1 Carbon) — evaluated after 200+ hours of use, with comparisons to the X1 Carbon and the Bambu Lab P2S.

Key Features Mentioned

Dual-Nozzle Setup (Multi-Color)

  • Designed for multi-color printing, described as “similar to H2D”.
  • Helps reduce waste for up to two colors.
  • For more than two colors, there is still significant purge waste.

Auxiliary / Secondary Nozzle System

  • The secondary nozzle uses a Bowden extruder mounted on the back.
  • Bowden is characterized as less precise than modern direct-drive systems.
    • Potentially worse retractions and pressure control.

Active Chamber Heater

  • Heats the chamber up to 65°C.
  • Target materials include ABS, ASA, and nylon.
  • Benefits reported:
    • Reduces warping with more uniform cooling
    • Improves layer adhesion and overall strength
  • Heating/cooling logic can prioritize heating vs cooling, auto-adjusting based on material.

Improved Enclosure Cooling + Exhaust

  • Exhaust port outputs out the back.
  • The exhaust system is positioned as an improvement/contrast to the P2S context:
    • On X2D it’s included, rather than a paid add-on for P2S.

AI / Automation Features

  • Active flow rate calibration
    • Claims compensation for damp filament and worn nozzles
  • Active vibration compensation
  • Detection tools mentioned:
    • Nozzle clump detection
    • Spaghetti detection
    • Others
  • Requires/uses a camera (included)
    • Described as usable, with good frame rate and lighting.

Chamber Lighting

  • Described as a “big step up” vs X1 Carbon.
  • Reduces the need for extra printed risers/LED mods.

General Print Quality

  • ASA prints “perfectly fine”.
  • PLA and PETG are described as “great”.

Pricing / Value Comparisons (As Stated)

  • X1 Carbon (combo): ~$1,500
  • X2D release price (combo): $899
  • X2D printer-only (no AMS 2 Pro): $649
  • Noted that X2D is “so close” in price to P2S:
    • $100 difference when not on sale
    • Reviewer suggests P2S is only slightly cheaper, despite X2D feeling more feature-rich.

Pros (User Experience Benefits)

  • Much cheaper than X1 Carbon, while feeling “newer” and “better” in multiple ways.
  • Dual-nozzle value is described as coming more from smarter support strategy than purely multi-color:
    • Uses PLA as an interface/support for PETG
    • Reported to improve support removal and surface finish
    • Example: a “perfect piece” after PLA/PETG interface removal
  • Active chamber heater works
    • ASA printed successfully with strong results
  • Consistent print quality
    • PLA and PETG perform well
  • Camera + lighting improvements
    • Easier monitoring without extra DIY lighting mods
  • AI diagnostics
    • Quality/fault detection features

Cons / Problems (Main Negatives)

PLA Cooling Limitation (Top Issue)

  • “One thing driving me nuts” is a cooling limitation for PLA.
  • X2D throws an error when chamber temps exceed 44°C while printing PLA.
  • Reviewer’s garage is about 40°C (104°F), leaving limited temperature headroom.
  • Workaround:
    • Remove the top lid completely
    • Open the front door wide
  • Reviewer finds this annoying because other printers don’t require it.
  • Additional side effect:
    • AMS placement causes Bowden tube rubbing after lid removal
    • Workaround mentioned: printing ASA glass risers

Bowden Extruder Issues

  • First print: filament tangled in the gears
  • Another case: filament broke between nozzle and extruder
    • Clearing required manually pushing filament through the hotend
    • Reviewer notes it wasn’t as easy as detaching a typical PTFE tube setup

Material / Usage Restrictions for the Aux Nozzle

  • Printer “only really wants” dual-color with PLA.
  • Other filaments can trigger warnings.
  • Avoid running normal TPU through the auxiliary nozzle
    • Can clog the extruder gear
  • TPU compatibility note:
    • Only TPU for AMS is compatible with the aux nozzle (per Bambu’s site).

Build Volume Reduction When Secondary Nozzle Is Enabled

  • Loses about 20 mm on the X-axis
  • Loses about 4 mm build height

Side-by-Side / Other Comparisons Mentioned

X1 Carbon vs X2D

  • X2D is cheaper and includes improved viewing via built-in lighting.
  • X1 Carbon price was much higher (~$1,500 combo), while X2D is dramatically lower.

X2D vs P2S

  • Reviewer says it’s confusing because they’re close in price ($100 difference).
  • Reviewer claims X2D seems like better value because it includes:
    • Active chamber heating
    • Exhaust port on the back
    • A more feature-packed overall feel
  • Reviewer recommends watching their P2S video for a full side-by-side.

Unique Points List (Distinct Claims / Actions / Issues)

  1. X1 Carbon was the reviewer’s second printer and changed their view of 3D printing.
  2. X1 Carbon is discontinued; X2D is newer and cheaper.
  3. X2D combo price: $899; printer-only $649 (no AMS 2 Pro).
  4. X2D dual-nozzle enables up to two-color printing with less waste.
  5. More than two colors still requires purging, creating waste piles.
  6. Dual-color works best with PLA; other filaments may trigger warnings.
  7. Secondary nozzle uses a back-mounted Bowden extruder.
  8. Bowden is less precise than direct drive; retraction/pressure control may be worse.
  9. Printing from the auxiliary nozzle alone works “pretty okay.”
  10. Best use-case: PLA interface supports for PETG, improving surface/support removal.
  11. Chamber heater supports ABS, ASA, nylon.
  12. Heater helps prevent warping and improves layer adhesion/strength.
  13. Cooling/heating settings can prioritize heat vs cool depending on material.
  14. Side intakes double as handles for easier moving.
  15. Exhaust port vents out the back; described as included (contrasted with P2S behavior).
  16. Cooling system struggles in a hot garage.
  17. Error occurs when chamber temps exceed 44°C while printing PLA.
  18. Workaround: remove top lid and open front door wide.
  19. AMS sits lower, causing Bowden tube rubbing, so the reviewer prints ASA glass risers.
  20. AI features include active flow calibration + compensation for damp filament/worn nozzles.
  21. AI includes active vibration compensation.
  22. Detection includes nozzle clump and spaghetti detection.
  23. Included camera is good (frame rate + lighting).
  24. Chamber lighting is improved over X1 Carbon; less need for DIY lighting mods.
  25. Print quality is good:
    • ASA prints “perfect”
    • PLA and PETG are “great”
    • PC blend mostly fine but some bottom warping
  26. Don’t run normal TPU through the auxiliary nozzle (can clog the gear).
  27. Only TPU for AMS is compatible with the aux nozzle.
  28. Multi-color demo: Gengar printed with Voxel PLA.
  29. Overall: excellent addition at current price, but the value comparison to P2S is confusing due to close pricing ($100).
  30. Reviewer suggests P2S may be an easier buy if you don’t need X2D’s extra features, but they lean toward X2D for built-in heating/exhaust.

Different Speaker Views / Contributors

  • Only one speaker: Adam (“Rad Dad’s Print Lab”). No other speakers were present in the subtitles.

Concise Verdict / Recommendation

The Bambu Lab X2D is presented as a strong upgrade and great value versus the old X1 Carbon, especially due to active chamber heating, improved camera/lighting, and its best-use advantage: PLA/PETG support interfaces.

However, the review’s biggest drawback is a cooling/heating limitation that causes errors above 44°C when printing PLA in hot ambient conditions—requiring lid removal and door opening.

If you mainly print ABS/ASA/nylon/PETG and can manage enclosure airflow, it’s recommended. If you frequently print PLA in warm rooms, the reviewer advises caution.
