Bambu Studio 2.5.0.65

This is the official public release of Bambu Studio v2.5.0.

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

Remote AMS drying support

It is now possible to start the drying operation for AMS 2 PRO and AMS HT connected to an H2D from Studio’s Devices page.

• Click the humidity button on the target AMS to open the control dialog to Start and Stop the drying feature.
• You can now dry filament while printing, but the drying temperature will be lowered during printing.

⚠ Minimum supported firmware version: 01.02.30.00（H2D）. Support for other models is under development.

Optimized prime tower strategy for PLA & PETG mixing print

Mixing PLA and PETG print is a common user scenario where one filament is used as support for the other one. We noticed that prime tower stability could be further improved under “low-adhesion” conditions. To address typical cases where bonding is difficult, we optimized the interface-layer temperature, extrusion, ironing, and flushing workflow:

• Interface-layer temperature boost for better adhesion: Added a new parameter to increase the interface-layer temperature. -1 means boosting it to the material’s maximum printing temperature.
• Extra pre-extrusion before printing the interface layer: Added new parameters for interface-layer pre-extrusion distance and length. Before printing the prime tower, the interface layer now performs a short pre-extrusion to build pressure and extend the extrusion path.
• Improved ironing strategy: Ironing is no longer applied to the interface layer. Added a configurable ironing area parameter for non-interface layers to preserve better flow behavior (especially for PETG).
• Reduced infill speed on the layer after the interface layer: By slowing down the infill of the next layer, the base becomes more stable, improving interface-layer adhesion.
• Additional flushing for the interface layer: Added flushing actions for the interface layer. Studio will do nozzle wiping before flushing rather than after flushing, and print the prime tower directly, reducing extrusion volume fluctuations and improving layer height consistency. Added a new parameter for interface-layer flushing length.
• Notch at the interface-layer starting point: Added a notch at the start of the interface layer to reduce extrusion pressure and prevent the nozzle from dragging due to an oversized blob.

With the above adjustments and validation tests, we confirmed this optimization effectively reduces prime tower collapse in scenarios such as PETG used as the support interface for PLA.

⚠️ Note: The above parameters are only visible in Developer Mode.

Ironing on the support interface

Introduce ironing capability for support interfaces. When printing without support materials, you can try this feature to achieve better support-surface quality. Thanks to @Noisyfox for the contribution.

Non-100% infill patterns for top/bottom surfaces

Top and bottom surfaces now support non-100% infill patterns, enabling more visual styles and creative effects. Thanks to @Buildasaurus for the contribution.

Standard 3MF color parsing support

Added support for importing standard 3MF files with color information. After import, the workflow is similar to multi-color OBJ: select the color data to map and apply colors.

ℹ️ Colored standard 3MF files are supported by tools such as Fusion 360/Meshmixer/OpenSCAD. Please refer to their documentation or the official 3MF standard site(3mf.io/) ↗ for details.

⚠ Note: Currently, only face color and vertex color data are supported. For texture-colored 3MF files, only face data will be imported.

Mesh subdivision

You can now right-click a part and choose Subdivide Part to apply Loop subdivision with multiple iterations. This is useful for models with low original mesh resolution.

⚠ Note:

1. Only meshes without non-manifold edges are supported.

2. Color attributes will be lost after subdivision. We recommend subdividing first, then painting and applying colors.

Scale to print volume

Right-click a selected part to scale it up to the maximum size supported by the current print volume, while keeping axis proportions unchanged.

Abort load/unload filament process

Studio now supports stopping the filament Load / Unload operations.

⚠ Note: Supported printers: A1/A1 mini/P1P/P1S. More models will be supported in future versions.
