Bambu Studio V2.8.4 Beta brings a series of user experience improvements. This version focuses on optimizing the UI and performance of texture import, adding prompts in model deletion scenarios to help prevent accidental operations, and improving the smoothness of both the Cut tool and Device page switching.

On the slicing engine side, this release optimizes the printing path for the top surface monotonic line infill pattern, reducing travel moves during printing. The more detailed the top surface of a model is, the more noticeable the improvement will be.

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.

Improvements

Optimized Texture Import with Improved UI Interaction and Stability

This version includes several improvements to the texture import workflow, enhancing import efficiency, user experience, and result stability:

1. Improved model repair speed during texture import.
2. Optimized UI interactions and improved the automatic filament matching logic.
3. The original model's rendering was changed from texture-map rendering to high-precision facet color rendering, so the preview now more closely matches the actual printed result.

Optimized Top Surface Monotonic Line Infill Path to Reduce Travel Moves

This version optimizes the printing path for the top surface monotonic line infill pattern, reducing travel moves during printing and improving print efficiency.

The improvement is more noticeable on models with more detailed and complex top surfaces.

Added a Prompt When Filament Shrinkage Compensation Is Not Applied to Painted Models

When slicing painted models, using different shrinkage compensation settings for different filaments may cause the final model dimensions to differ from expectations. Therefore, in this scenario, the slicing engine does not apply filament shrinkage compensation parameters by default.

When the shrinkage factor in the material settings is not the default value of 100%, and the current plate contains painted models, Bambu Studio will now display an informational prompt indicating that filament shrinkage compensation will not take effect in this scenario.

Other Improvements

1. Optimized the loading speed of the Device page, reducing the waiting time after entering the page.
2. Improved the UI interactions and visual design of the AMS settings area on the Device page.
3. Optimized the performance of the Cut tool, making dovetail cutting operations smoother.
4. When deleting a filament that is already used by a model, Bambu Studio will now show a prompt firstly to help prevent accidental deletion and unexpected filament reset on the model.
5. When sending a model imported from MakerWorld to the print, Bambu Studio will now use the user's current project name instead of the original configuration name.
6. Improved the text input experience in the Text tool, adding support for line breaks with Enter and line spacing control. (PR #12176). Thanks to @jeremykenedy.
7. Show a warning message when only non-printable objects are left on the plate (#11849).

Bug Fixes

1. Fixed a security issue caused by a stack buffer overflow in ADMesh stl_read. (PR #12153). Thanks to @MAVProxyUser.
2. Fixed an issue where the source code could not be built correctly in certain build environments. (PR #11895). Thanks to @hadess.
3. Fixed an issue where, in some cases, the first-layer print height was incorrect when printing with Raft enabled in Vase Mode. (PR #11965). Thanks to @mvanhorn.
4. Fixed "Open in Bambu Studio" not working on aarch64 and cURL 8.x (PR #11804). Thanks to @hadess.
5. Fixed a potential crash when painting colors (#12213).
6. Fixed a potential crash when importing OBJ files on macOS (#12169).
7. Fixed X2D Bowden extruder retraction length not being applied correctly in custom profiles (#10404).
8. Fixed incorrect popup windows for support material (#12165).
9. Fixed the issue where a popup could not be closed after syncing on macOS (#11983).
10. Fixed the issue where translucent filament was displayed as black in dark mode (#11376).
11. Fixed a potential crash during slicing (#10626).
12. Fixed a potential crash on macOS (#11265).

Bambu Studio V2.8.4 Beta 带来了一系列体验优化。本版本重点优化了纹理导入功能的 UI 交互与处理性能；新增模型删除场景下的提示，降低误操作风险；提升了切割工具与设备页切换的流畅度。

在切片引擎方面，本版本优化了顶面单调线填充图案的打印路径，减少打印过程中的空驶移动。对于顶面细节越复杂的模型，该优化带来的打印效率提升越明显。

您可以从 Bambu Studio on Flathub 上下载适用于 Linux 的 Flathub 版本。 Flathub 版本由 @hadess 维护。感谢他为此付出的出色工作

注意：使用 Beta 版本保存的 3MF 文件暂不支持上传至 MakerWorld。如有上传需求，请使用正式发布版本。

改进

优化纹理导入功能，改善界面交互与功能稳定性

本版本对纹理导入流程进行了多项优化，提升导入效率、界面体验和结果稳定性：

1. 提升纹理导入阶段的模型修复速度。
2. 优化 UI 交互体验，并改进耗材自动匹配逻辑。
3. 原始模型的渲染方式由纹理贴图渲染调整为高精度面片颜色渲染，使预览效果更加接近真实打印结果。

优化顶面单调线填充图案的打印路径，减少空驶

本版本优化了顶面单调线填充图案的打印路径，减少打印过程中的空驶移动，从而提升打印效率。

对于顶面细节越多、路径越复杂的模型，该优化效果越明显。

涂色模型场景下新增耗材收缩补偿不生效提示

在涂色模型切片场景中，如果不同耗材启用了不同的收缩补偿设置，可能会导致模型尺寸不符合预期。因此，切片引擎在该场景下默认不会使用耗材的收缩补偿参数。

当材料设置中的收缩系数不是默认的 100%，且当前盘中的模型为涂色模型时，Bambu Studio 现在会显示信息提示，告知用户该场景下耗材收缩补偿不会生效。

其他优化

1. 优化设备页加载速度，缩短点击进入设备页后的等待时间。
2. 优化设备页 AMS 设置区域的交互界面与视觉效果。
3. 优化切割工具性能，使燕尾榫切割操作更加流畅。
4. 删除已被模型使用的耗材时，软件会先显示提示，避免误删导致模型耗材被意外重置。
5. 从 MakerWorld 导入的模型在发送打印时，将使用用户当前的项目名称，不再使用原始配置名称。
6. 优化文本工具的输入体验，支持使用 Enter 换行，并新增行间距控制(PR #12176)。感谢@jeremykenedy
7. 优化无可打印件时的提示(#11849)。
