Bambu Studio 2.7.1.57

V2.7.1 Public Release is a new version based on 2.6.1 Public Beta ↗ and 2.7.0 Public Beta ↗. Compared to V2.6.0 Public Release, this version adds support for the Bambu Lab A2L ↗, introduces important new features such as Texture-to-Color Painting and the Filament Manager, along with various 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.

Known Issue: Startup lag on macOS 26.5 and later

Some users running macOS 26.5 or 26.5.1 may experience UI lag and steadily increasing memory usage after launching Bambu Studio. In some cases, this can lead to application crashes. The issue appears to be related to the initialization of the built-in WebView and is currently under investigation. See #11004 ↗ / #10968 ↗ for details.

Temporary workarounds

• Use the pre-release version ↗.
• Minimize and then restore/maximize the Bambu Studio window after launch using the window buttons in the top left.
• Open any subpage, such as Preferences.
• Roll back to Bambu Studio 2.6.0 Public Release ↗ .

We are actively working on a fix and will release it as soon as possible. Thank you for your patience.

⚠️ Notice for V2.7.0 Public Beta Users: Due to the addition of new machine preset configurations and related placeholders in this release, slicing with V2.7.0 may result in errors in certain scenarios. Please upgrade to V2.7.1 Public Release as soon as possible to avoid these issues.

Features

Gradient Color Curve Control for Multi-Color Printing

Gradient effects now support more flexible layer height control. A Color Curve Panel has been added for gradient colors, allowing users to freely add anchor points (left-click to add, right-click to remove) and drag the color curve to customize the blending ratio of two colors at different Z heights, enabling richer gradient effects.

Liveview Full-Screen Support

Liveview now supports full-screen display and playback. Thanks to @bdpdx for the contribution, we optimized some frontend interaction features based on his work.

💡 Tip: Press ESC to exit full-screen mode.

Alternate Extra Wall

When enabled, an extra wall is added to alternating layers while other layers retain the original wall count. This option is suitable for improving model structural strength without needing to add extra walls on every layer. Thanks to contributions from @igiannakas and @jomixlaf.

⚠️ Note: This option is mutually exclusive with Spiral Vase Mode (or 0% infill).

Improvements

Texture-to-Color Painting Feature Optimization

• Multi-texture model processing optimization: Improved color sampling stability when importing multi-texture models, including fixes to UV mapping for multi-texture atlases, improved base color material processing logic, and optimized color clustering algorithm and smoothing control.
• New mesh error detection and repair confirmation workflow: Automatically detects mesh errors when importing textured models, improves the built-in repair capability to ensure model watertightness, and can invoke the Windows mesh repair tool when necessary.
• FBX file import support.

Filament Manager Optimization

• Supports multi-selection for batch adding filaments.
• Added an overwrite confirmation prompt when the same spool of filament is added again (via RFID recognition).
• Other interaction and UI detail optimizations.

Improved PETG Prime Tower Stability with Filament Track Switch

This update improves the prime tower's stability during printing by disabling flat ironing (setting the ironing area to zero) while keeping line ironing, and by adding extra extrusion next to the prime tower.

LAN Mode Auto-Saves Connection Information

LAN connection information can now be saved locally, eliminating the need to re-bind LAN printers after restarting Studio. (#7891, #8270, #8409, #9042)

Other Improvements

1. Fixed GMP build issue with GCC15. Thanks to contributions from @hadess and @c2h5oh.
2. Added support for building with VS 2026 and CMake 4.2.
3. Updated the display and interaction effects of filament controls in the assembly view.
4. Changed the default Paint Fill mode to Edge Detection mode.

Bug Fixes

1. To address potential collapse issues caused by chamfers introduced at the bottom of supports in certain scenarios, the bottom 2mm of supports now defaults to 2 walls (this behavior is disabled when 0 or single wall is specified). (#10542, #10775)
2. Added a new "Order-independent overlap carving" option (disabled by default) to prevent the Object List sequence from affecting slice results of embedded models in certain scenarios.
