Bambu Studio 2.4.0.70

V2.4.0 adds support for Bambu Lab H2C ↗, along with several new features and bug fixes.

Support for Bambu Lab H2C

The right extruder of Bambu Lab H2C supports up to 6 nozzles. Its slicing workflow is generally aligned with Bambu Lab H2D, with the following adaptations and optimizations for H2C-specific features. View Bambu Wiki ↗ for more information.

• Slicing setting sync with printer capabilities: Supports Hybrid Mode slicing with both high-flow and standard nozzles.

⚠ Note: Slicing with mixed nozzle diameters is not supported.

• Purge mode options:Allows switching between Standard mode and Purge Saving mode for flushing.View Bambu Wiki ↗ for more information to get.

• Map prints to a specific nozzle: In addition to mapping AMS slots, the right extruder supports printing specific filament with designated nozzles.

• Nozzle details on the device page: The Device page now shows detailed nozzle information and supports reading all nozzle data automatically.

New Features

Use different filaments for different features (Developer Mode)

In Developer Mode, under Object List → Others → Advanced, you can now assign walls, solid infill, and sparse infill of a single Object to different filaments. This feature helps unlock the full potential of multi-extruder printers such as H2D and H2C, enabling more advanced multi-material printing strategies. The feature is inspired by the corresponding implementation of PrusaSlicer and OrcaSlicer, with a series of related issues fixed on top of that. Thanks to @SoftFever and @ianalexis for their contributions.

⚠ Note:

- This option is only visible in Developer Mode.

- It is available per Object only, and not as a global setting.

Sparse infill line multiplier

You can now multiply the number of sparse infill lines. This can be configured under Process presets → Strength → Sparse infill. It can improve part strength and thanks to @RF47 for the great contribution.(#1041 ↗)

⚠ Note: This feature is currently not supported for the following infill patterns: Concentric, Line, Hilbert Curve, Archimedean Chords, Octagram Spiral, Crosshatch, Zig Zag, Cross Zag, Locked Zag.

Align & distribute objects or parts

You can now align and distribute multiple selected Objects / Parts along the X, Y and Z axes. After selecting multiple objects or parts, you can access these tools via the Move gizmo, or via the right-click menu → Align/Distribute.

💡Tip: Ctrl + left-click to multi-select objects, and Alt + left-click to multi-select parts.

Move plate

You can now move an entire plate at once: Right-click the selected plate and choose “Move plate” to translate that plate as a whole to a specified position. Thanks to @Azio-Pantheon for the contribution.

Editable Project page

We have refreshed the project page ui and added support for editing project page content(#4546 ↗, #2111 ↗):

• Click the Edit button in the top-right corner of the project page to enter edit mode.
• After editing, click Save to apply your changes.

⚠ Note: When your 3MF is uploaded to MakerWorld, the original project page content inside the 3MF will be overwritten by the content filled in on MakerWorld.

Outer wall & infill interlocking

Shoe models expose sparse infill that is only weakly bonded to the walls (as in the picture), making the connection between walls and infill fragile. To address this, we have added an “Outer wall & infill interlocking” feature under Process → Strength → Walls.

When enabled, an interlocking region is added to the inner side of the walls (non-visible surface) and additional Z-direction staggering is introduced. This feature helps improve the model’s strength in both the horizontal and Z directions.

Improvements

1. E3D nozzles now support high-flow slicing on X/P series printers.

💡Tip: Users can purchase an E3D high-flow nozzle and switch to high-flow slicing in Studio.

1. GCodeViewer update: The advanced GCodeViewer may provide better performance on some PCs especially those with dGPU(discrete GPUs).

• On Windows / Linux with OpenGL ≥ 3.2, the new G-code Viewer is enabled automatically(you can disable it under Preferences → 3D Settings).
• Other platforms will continue to use the legacy viewer for now.

1. Improved the interaction for extruder parameter settings: Improve visual cues to prevent cases where users modify parameters without switching to the correct nozzle type, causing the changes to have no effect.

1. Optimized remaining-filament display for white filament in AMS: When the estimated remaining amount is below 10%, it will now be uniformly shown as 10%.
2. G-code Viewer state persistence: After slicing, the G-code Viewer now remembers whether it was expanded or collapsed.
3. Updated parts of the Helio optimization UI. Thanks to @HelioPri for the support.
4. Boolean operations list select-all: In the Boolean operations panel, a “Select All” button has been added to the list for faster selection.
