Features

Supports designing and generating model assembly guides directly within Studio

Step-by-step assembly guide for complex models (new): Import a STEP file to automatically split it into assembly steps, with visual guidance to help you understand how parts fit together.

• Edit the objects/parts of each step through the object tree
• Two viewing modes — X-ray and "Show current step only" — for easier positioning
• Supports exploded-view animation and multiple annotation types (snap-fit / rectangle / text); generate an assembly walkthrough animation in one click, with a unified camera view and auto-layout
• One-click export to PDF / Markdown / MP4
  For details, see the wiki: https://e.bambulab.com/t?c=T0HuraoU2gH6ufRk

Added Counterbore Hole Bridging Support

A new "Counterbore hole bridging" option under Quality → Advanced. It lets you print counterbore/countersunk holes without supports, with three modes:

• None: Default behavior; no bridging is applied.

• Partially bridged: Bridges only the overhanging ring region while leaving the center open.

• Sacrificial layer: Generates a single full bridged layer over the entire hole as a sacrificial layer, providing a base for the layers above.

Improvements

Time-lapse Video Quality Improved Across All Printer Models

Optimized the tool head landing point to prevent camera shake caused by uncertain landing positions, and enhanced the viewing experience of time-lapse photography videos. Ensure that the tool head during time-lapse photography is as far away from the camera as possible to avoid any obstruction.

Other Improvements

1. For the H2D, this Beta adds a foreign object detection toggle and enhanced curve-planning support, and improves circular hole compensation.
   ⚠️ Minimum required firmware version: 01.03.50.00 (H2D)
2. Fixed an issue where dialogs popped up repeatedly in some not-logged-in scenarios.
3. Added a confirmation dialog when clicking to clear "Recent files."
4. Updated the price information for some filament presets.
5. When the flushing-volume matrix automatically calculates flushing volumes, it now accounts for switching between official material types: for example, switching between PLA and PETG automatically increases the flushing volume to prevent insufficient interlayer adhesion.
6. Added support for the 3Dconnexion SpaceMouse Pro Wireless Bluetooth Edition. Thanks to @mpaperno for the contribution.

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.

3. Fixed an issue where the collision detection algorithm in sequential printing did not correctly account for skirt spacing.
4. Fixed several errors in sequential printing and some issues during plate size switching. (#8770)
5. Fixed an issue where slicing was interrupted by empty or un-sliceable plates when slicing all plates. (#10296)
6. Fixed abnormal display of model collision risk zones in sequential printing scenarios. (#10434)
7. Fixed an issue where nozzle temperature was displayed incorrectly when importing filament presets in certain scenarios. (#10583)
8. Fixed an issue where PA value requests failed in certain scenarios. (#10351)
9. Fixed an issue where printing could not be initiated after slicing on the A1 mini in certain scenarios. (#10418)

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.

⚠️ 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)

⚠️ 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.

ℹ️ Note: Translations for some languages are still being refined; a small number of UI strings may temporarily appear in English.

4. Added PLA Pure filament presets.
5. Filament Manager now displays official filament color information, with support for multi-color and gradient filaments, as well as cloud sync.

Bug Fixes

1. Fixed a potential crash when modifying infill density in sequential printing mode. (#10350)
2. Fixed an issue where certain threshold angles in support generation were incorrectly clamped. (#10553)
3. Fixed an issue where the K value did not update in time in some scenarios. Thanks to @maziggy for the contribution. (#9984)
4. Fixed an issue in Filament Manager where some languages were not displayed correctly; untranslated strings now fall back to English. (#10428)
5. Fixed a potential crash when clicking "View all object settings". Thanks to @hadess for the contribution. (#10607)
6. Fixed an issue on Linux where the parent dropdown lost focus when a sub-dropdown was opened.(#10175)
7. The high-shrinkage filament warning is now shown as a daily tip instead of every time.
8. Fixed an issue where a customized plate type was ignored when sending a print job. (#10171)
9. Fixed an issue where official Bambu Lab filaments were misidentified as third-party filaments in AMS in certain scenarios. （#10279）
10. Fixed an issue in Flow Rate Calibration where the speed was adjusted instead of the flow rate.（#10005）
11. Fixed a crash when switching to the Device tab on multi-AMS printers.（#10364）

Bambu Studio V2.6.1 Beta is built on V2.6.0 Public Release, with the Filament Manager introduced as a key new feature, along with several improvements and bug fixes.

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)

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.

⚠️ Minimum supported firmware version: 01.08.00.00 (A1 / A1 mini)

Bug Fixes

1. Fixed an issue where the gradient color mixing order of the first layer and top layer in color mixing models was incorrect.
2. Fixed an issue where lowercase "e" could not be typed in the text tool under the specific keyboard layout. The shortcut for 'Show labels by Object' has also been updated from Ctrl+E to Ctrl/Command+Shift+E.
3. Added an import warning for non-closed STP models.
4. Fixed an issue where the print bed was abnormally filled with model copies in certain scenarios. (#8841)
5. Fixed an issue where the 0.6 mm nozzle could not be selected by scrolling on H2C when sync printer.(#10059)

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.

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.

V2.5.3 adds support for the Bambu Lab X2D, along with new features, improvements, and bug fixes. Please see the release logs of v2.5.1 Beta and v2.5.2 Beta 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 page.

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 printing efficiency.

ℹ️ Tip: The Filament Track Switch will only appear in printer presets and the Devices page after syncing a device with the Filament Track Switch installed via the Sync button. Smart assignment mode will also be enabled in slicing mode.
⚠ Minimum supported firmware version: 01.02.00.00(H2C)、01.01.00.00(X2D)

Linear Fan Speed Transition

Part cooling fan and auxiliary fan speeds now support more precise layer-by-layer control. Fan speed transitions linearly from the configured value at the starting layer to the target speed. This helps improve cooling conditions near the first layer, reducing the risk of warping or first-layer failures caused by sudden temperature drops.

"Enable Tower interface features" available in Developer Mode for H2D/H2C/X2D

When enabled, it applies dedicated temperature, pre-extrusion, and flushing parameters to the prime tower contact layer, improving print quality during multi-material transitions and significantly reducing the risk of prime tower collapse when printing with filaments of significantly different viscosities.

Assembly Overview Preview

Added an Assembly Overview preview feature that allows users to preview the overall assembly effect in real time after changing colors or painting. The preview angle can be adjusted using the viewpoint button in the View menu. This feature can be enabled or disabled in Preferences -> 3D Settings. View Bambu Wiki for more details.

ℹ️ Tip: For the best preview experience, it is recommended that 3MF creators import the complete assembled model file rather than individual separate parts.

Reduced Risk of Collapse During Printing

This update introduces optimizations from both support and prime tower perspectives to reduce the risk of collapse during printing:

• Wipe tower ironing is now enabled by default on P2S: In multi-material printing scenarios, this effectively improves adhesion between wipe tower layers, reducing the risk of wipe tower collapse.
• A chamfer has been added to the base of tree supports (expanding outward from a height of 2mm), effectively reducing the risk of support collapse. The radius calculation logic for support node merging has also been optimized, improving the consistency and accuracy of support structures.

Static Preview Frame on Liveview Connection or Switch

When Liveview is not auto-playing in Cloud or LAN mode, the Devices page now displays a static preview frame of the current device.

⚠ Minimum supported firmware version: 01.02.00.00（P2S)，01.01.00.00（X2D）

Fuzzy Skin: Additional Noise Types and Generator Modes

In addition to the Classic mode, Fuzzy Skin now supports 4 new noise types:

• Perlin
• Billow
• Ridged Multifractal
• Voronoi
  New generator modes have also been added:
• Displacement: Creates texture by offsetting the nozzle left and right relative to the original path.
• Extrusion: Pattern is formed by varying the amount of extruded plastic (nozzle path stays straight).
• Combined: Displacement + Extrusion. Similar look to Displacement but fills gaps between perimeters.

ℹ️ Tip: Extrusion and Combined modes only take effect when using Arachne (variable line width) mode with "Fuzzy skin thickness" not exceeding actual line width.

Thanks to @Arachnid for the contribution.
