##### Features
###### Texture-to-Color Painting
Convert textured models directly into multicolor painting on the model surface. Ideal for applying colored artwork (logos, decorative patterns) to 3D models in multicolor printing. Currently supports OBJ, glTF, and GLB textured model imports.
<img width=)
> ⚠️ Notes:
> - Single-textured models are recommended for now: conversion quality for multi-texture models will be improved in upcoming versions.
> - Loading multiple textured models for conversion at the same time is not yet supported. Please import them one at a time.
> - Draco-compressed glTF / GLB is not yet supported: support will be added in a future release.
> - For models with significant mesh defects, we recommend repairing them before import. This feature provides limited mesh auto-repair, but cannot guarantee a watertight result.
> - Due to a third-party library depended on, import errors may occur in some scenarios on macOS and Linux. We will continue to improve this in upcoming versions.
##### Improvements
###### Mesh Defect Diagnostics Improvements
Refined parts of the mesh defect detection algorithm:
- Improved detection accuracy for non-manifold edges.
- Open edges are now counted as a separate category.
> ℹ️ Note: Non-manifold edges are reported as Error, and open edges are reported as Info.
###### Gradient Effect Supported Per-Part Gradient
A new "Enable per-part gradient effect" option has been added to the Mixed Filament gradient settings:
- On: each part within a combined object receives its own gradient, transitioning smoothly from its own bottom layer to its own top layer.
- Off (default): preserves the existing behavior, applying a single gradient across the entire object's Z range.
Particularly useful when printing combined objects made up of parts with different heights — each small part can now show a complete, self-contained gradient.
###### Painted Color Information Preserved After Plane Cut
Painted color information is now preserved after a Plane Cut, so there's no need to repaint the model after cutting. Special thanks to @solidblu for the contribution. (#[10613](https://github.com/bambulab/BambuStudio/pull/10613))
> ⚠️ Note: Minor alignment differences may appear on painted facets near the cut surface.
##### Other Improvements
1. Migrated to WebKitGTK 4.1 for better compatibility with modern Linux distributions. Thanks to @jijinbei for the contribution.
2. 3D view preset shortcuts (Ctrl + [0–7]) now work even when the canvas doesn't have focus. Thanks to @mpaperno for the contribution.
3. Traditional Chinese language entry added: Traditional Chinese option is now available under Preferences → Language, allowing Traditional Chinese users to use Bambu Studio in their preferred language. Thanks to @hezhen0816 for the contribution.

##### Features
###### Filament Manager
The Filament Manager is designed to manage users' filament information and usage status. The current version supports:
- Viewing, editing, and deleting filaments, with support for search, grouping, and filtering.
- Automatically reading filament information from AMS, or entering it manually.
> ⚠️ Note:
> 1. Filament modifications (adding / editing / deleting) and remaining amount sync in the Filament Manager are currently only supported when the device is connected to the internet.
> 2. Filament Manager data is stored in Bambu Cloud and synchronized between Bambu Studio and Bambu Handy.
##### Improvements
###### Optimized Filament Track Switcher Retraction Logic for H2C
To improve printing efficiency, the retraction target for printers equipped with a Filament Track Switcher has been changed from the AMS to the Filament Track Switcher itself, reducing the retraction distance and saving time during filament loading and unloading.
> ⚠️ Minimum supported firmware version: 01.02.00.00 (H2C)
###### Improved Post-Processing Script Slicing Reminder
When a project file contains post-processing scripts, a pop-up reminder will appear before slicing, prompting users to review the script content again for improved safety.([#10256](https://github.com/bambulab/BambuStudio/issues/10256))
###### Added Auxiliary Fan(AUX Fan) Display in GCodeViewer
###### Other Improvements
1. Updated the color prediction method for color mixing printing. Thanks to @ratdoux for the contribution.
2. For multi-nozzle printers printing with only a single nozzle, the 'nozzle offset calibration' is now automatically disabled.
3. The filament mapping limit for A1 / A1 mini has been increased from 16 to 32.

### v02.06.00.51 — 2.6.0 Public Release（Hotfix）
- Date: 2026-04-17
- Version: v02.06.00.51
- Original notes: https://github.com/bambulab/BambuStudio/releases/tag/v02.06.00.51
- Permalink: https://whatsnew.fyi/product/bambu-studio/releases/v02.06.00.51
- Labels: Platforms: Desktop
- **fixed** — Fixed an issue where an incorrect End G-code caused the P2S nozzle temperature to not cool down properly after printing
- **fixed** — Fixed an issue where A1 sliced files could not start printing in some scenarios
- **fixed** — Fixed an issue where H2C slices always assigned to the left nozzle in filament-saving mode
- **changed** — Clarified that the current code repository contains Full Spectrum color prediction code
This release is a hotfix based on the V2.5.3 Public Release, primarily addressing an issue in which the **P2S nozzle temperature would not cool down properly after printing**. Since delivering this fix through a preset update could affect existing presets for some users on **V2.5.0**, it is instead released as **V2.6.0** to minimize the impact on existing users.
If you are using a **P2S** and your current Studio version is **V2.5.3**, we recommend upgrading to this version as soon as possible to avoid this issue.
You can download the flathub version for linux from [bambustudio on flathub](https://flathub.org/apps/com.bambulab.BambuStudio)
The Flathub version is maintained by @hadess and thanks to him for his outstanding work.
##### Statement on the Color Mixing Feature
After receiving feedback from the community, we re-examined the implementation and code paths of the current version. During development of this feature, we evaluated multiple color-mixing prediction approaches, including the **RGB mixing approach** and **Full Spectrum’s prediction implementation**. Under the validation conditions at the time, we chose the **RGB mixing approach that is currently used in v2.5.3**.
During development, to facilitate side-by-side evaluation of different approaches, we retained implementation code under evaluation. However, we did not clearly indicate its runtime status in our previous notes. This omission caused confusion for users and the community, and we sincerely apologize.
Next, we will do two things:
1. Correct the relevant wording in this release and clearly state that the **current code repository contains Full Spectrum color prediction code.**
2. Based on further validation and more real-world feedback, move forward with formally integrating Full Spectrum’s color prediction implementation.
We thank @justinh-rahb and @ratdoux for their contributions in this area, and we also appreciate the open-source community for identifying and monitoring this issue.
##### Bug Fixes
1. Fixed an issue where an incorrect End G-code caused the P2S nozzle temperature to not cool down properly after printing.
2. Fixed an issue where A1 sliced files could not start printing in some scenarios.
3. Removed several unnecessary prompts.
4. Fixed an issue where H2C slices always assigned to the left nozzle in filament-saving mode.
### v02.05.03.62 — 2.5.3 Public Release
- Date: 2026-04-14
- Version: v02.05.03.62
- Original notes: https://github.com/bambulab/BambuStudio/releases/tag/v02.05.03.62
- Permalink: https://whatsnew.fyi/product/bambu-studio/releases/v02.05.03.62
- Labels: Platforms: Desktop
- **added** — Support for the Bambu Lab X2D printer
- **added** — Color Mixing experimental feature allowing mixing of 2 or 3 filaments of the same type with Normal and Gradient modes
- **added** — Filament Track Switch support enabling filament from the AMS to be fed into both left and right nozzles of multi-extruder printers
- **added** — Linear Fan Speed Transition for part cooling and auxiliary fans with layer-by-layer control
V2.5.3 adds support for the [Bambu Lab X2D](https://bambulab.com/en-us), along with new features, improvements, and bug fixes. Please see the release logs of [v2.5.1 Beta](https://github.com/bambulab/BambuStudio/releases/tag/v02.05.01.52) and [v2.5.2 Beta](https://github.com/bambulab/BambuStudio/releases/tag/v02.05.02.51) for the complete list of changes with respect to v2.5.3.The full release notes of v2.5.3 can be found on the Bambu Lab Wiki under the [Bambu Studio Changelog](https://wiki.bambulab.com/en/software/bambu-studio/release/release-note-2-5-3) page.
You can download the flathub version for linux from [bambustudio on flathub](https://flathub.org/apps/com.bambulab.BambuStudio)
The Flathub version is maintained by @hadess and thanks to him for his outstanding work.
##### Features
###### Color Mixing (Experimental feature)
The Color Mixing feature allows you to mix multiple filaments in the same print to create new colors by adjusting the ratio. To use it, click "Add Mixed Filament" at the bottom of the filament list to configure them in the pop-up dialog.
- Supports mixing **2** or **3** filaments of the same type.
- Mixing modes:
- **Normal mode**: Adjust the ratio of two or three colors using the color bar or color triangle in the ratio panel, or select directly from the recommended colors below. With the Bambu Lab CMYK filament kit, a wide range of colors can be achieved — for example, all the boats shown in the left image were printed using the CMYK filament kit on a single plate.
- **Gradient mode**: Create gradient color transitions between two colors for rich transitional effects, as shown in the right image.
The color prediction part was based on @ratdoux’s approach in OrcaSlicer-FullSpectrum. We thank him for his outstanding work. All other parts were independently developed by the Bambu Studio team.
> ⚠ Note:
> 1. This feature is experimental. Uploading 3MF files that include mixed filaments to MakerWorld is not currently supported.
> 2. This feature is only suitable for near-vertical walls. It is not recommended for sloped surfaces or top/bottom surface color layering.
> 3. Single-nozzle printers are not recommended for this feature due to frequent color changes and increased filament consumption. A multi-nozzle printer is recommended for better results.
> 4. With a 0.4mm nozzle, a base layer height of 0.12mm and a mixed layer height of 0.2mm are recommended for more uniform color mixing results. Avoid extreme layer height ratios, as excessively small layer heights may trigger melt fracture and degrade print quality.
> 5. The color preview model for layered colors is not yet fully accurate. Users with high color requirements are advised to print a small test piece first and fine-tune the settings based on the observed results.
###### Filament Track Switch Support
The Filament Track Switch enables filament from the AMS to be fed into both the left and right nozzles of multi-extruder printers (H2C/X2D). Slicing allows a single filament to be printed using different nozzles in this mode, which effectively reduces unnecessary flushing and significantly improves multi-color
