Bambu Studio V2.8.1 introduces Decompose Color, E3D nozzle support, and device-page filament management, along with a range of improvements and bug fixes.
You can download the Flathub version for Linux from Bambu Studio on Flathub
The Flathub version is maintained by @hadess ; thanks to him for his outstanding work.
Note: 3MF files saved in the Beta version are temporarily not supported for upload to MakerWorld. If you need to upload, please use the official release version.
Features
Color Prediction & Decompose Color
Updated the color prediction algorithm for the CMYW and RYBW combinations of Bambu PLA Basic, delivering more accurate layered-color results with these two combinations. Also introduced Decompose Color, which automatically breaks a target color down into the optimal filament combination.
- Decompose colors from the filament list, or into a specific color combination (currently only the CMYW and RYBW combinations of Bambu PLA Basic are supported).

- Automatic Decompose Color for textured models: after importing a colored model, the software automatically matches your filament library to generate a decomposition scheme, with no manual color setup required.
Device-Page Filament Management
- Bind filaments from the Filament Manager to editable slots.
- View each filament's presence (mount) status and the device it's currently on.
- When loading a Bambu Filament that hasn't been added yet, quickly create a new spool or bind it to an existing filament right from the device page.
E3D Hotend Integration
- Added a new "E3D High Flow" nozzle type, supported on H2D, H2S, H2C (left head only), X2D, and P2S.
- Shown in the sidebar only for 0.4 / 0.6 mm nozzle diameters.
Remaining Filament Reminder
Added remaining-filament reminder support for the H2D.
⚠️ Minimum supported firmware version: 01.03.50.00 (H2D)
- Prompts remaining filament status during print-related workflows.
- Makes it easier to prepare a filament change in advance, reducing the risk of print interruptions.
Improvements
Preferences Page Redesign
- Restructured the layout and presentation of the Preferences page.
- Makes it easier and faster to find and adjust commonly used options.
Assembly Guide Improvements
- Fixed an issue where splitting or merging objects in the Prepare view affected the tree structure in the Assembly view.
- Added support for adding parts to assembly steps from either the list or the canvas.
- Added "face-to-face" and "point-to-point" alignment, with Gizmo-based assembly.
- Improved large-text rendering for better label readability.
Filament Track Switch
- H2D now supports the Filament Track Switch.
⚠️ Minimum supported firmware version: 01.03.50.00 (H2D)
Other Improvements
- Mixing ratios for layered colors can now be entered manually, improving precision for two or three-color blends.
- Added a Wiki help link to the A2L Quick Mode interface.
- Improved flush time estimation for H2D: heating and cooling are now calculated separately, making multi-color flush duration more accurate.
- Generating a PA calibration tower no longer overrides the wall speed defined in the preset.
- Updated Ukrainian translation. Thanks to @Tarasovych for the contribution.
- Restored the --datadir argument, allowing a custom configuration directory (network paths supported). Thanks to @mpaperno for the contribution.
- Builds can now optionally use the system-provided GMP / MPFR libraries. Thanks to @hadess for the contribution.
- When the system temp directory is low on space, slicing temporary files are now stored in the data directory instead, reducing export failures for large models (especially on Linux systems with a small /tmp). Thanks to @BenJule for the contribution.
- When a project has unsaved changes, an "*" is now prepended to the window title and automatically removed after saving (all platforms). Thanks to @BenJule for the contribution.
- Added portable operation: when a local configuration folder is detected, it takes priority, making it easier to run multiple versions side by side. Thanks to @mpaperno for the contribution.
Bug Fixes
- Fixed first-layer sagging when using a single-layer raft, and fixed the object's first-layer infill incorrectly using the initial-layer speed. (#10897)
- Fixed a slicing crash after fully color-painting a modifier. (#11152)
- Fixed an issue where setting the language to Traditional Chinese (zh_TW) was reset to en_GB after restart. (#11188 )
- Fixed a startup crash caused by interacting with the setting recommendation popup after enabling Alternate extra wall. (#11236)
- Fixed max_bridge_length not taking effect, which caused supports to still be generated in the sacrificial-layer area of bridged counterbore holes. (#11317)
- Fixed sorting by filament name not working in the Filament Manager. ( #11042 )
- Fixed the Filament Manager tab content being incorrectly zoomed in when resizing the window on macOS. (#11267)
- Fixed spelling errors in UI text such as "paramters" and "overwriten". Thanks to @BenJule for the contribution. (#11248)
- Corrected the custom filament vendor name from "3Dgunius" to "3Dgenius". Thanks to @BenJule for the contribution. (#11250 )
- Fixed multiple spelling errors in UI text. Thanks to @BenJule for the contribution. (#11254)
- Fixed incorrect filament selection in multi-nozzle manual calibration. Thanks to @disaster123 for the contribution. (#11117)
- Fixed a download failure in the Homebrew release workflow when macOS assets were not yet available. Thanks to @BenJule for the contribution. (#11291)
- Fixed G-code export failures always reporting "disk full" instead of showing the actual system error. Thanks to @BenJule for the contribution. (#11066)
- Fixed file dialogs defaulting to the process working directory instead of a sensible path. Thanks to @BenJule for the contribution.(#11256)
