Release-note preview

A plain-text excerpt from the publisher’s release notes. Open the official release for the complete and current text.

Publisher notes are shown in their original source language. This excerpt is not machine-translated.

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.

You can download the flathub version for linux from bambustudio on flathub ↗ 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 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.
