Bambu Studio 2.8.0 Beta Adds Assembly Guides and Counterbore Bridging
Bambu Studio 2.8.0 Public Beta adds STEP-based Assembly Guide tools and counterbore hole bridging, with a MakerWorld upload caveat for beta-saved 3MF files.
Checked July 11, 2026: Bambu Studio 2.8.0 is a public beta that adds STEP-based Assembly Guide views and counterbore hole bridging. Its release notes also warn that 3MF files saved in the beta cannot currently be uploaded to MakerWorld. Bambu Lab has not published a stable-release date.

Bambu Studio 2.8.0 Beta adds STEP assembly guides and counterbore bridging
Bambu Lab released Bambu Studio 2.8.0 Public Beta on GitHub on June 25, 2026. Its new Assembly Guide accepts a STEP file and organizes the model into ordered build steps. The release notes list X-ray and show-current-step-only views, exploded-view animation, annotations, and one-click export to PDF, Markdown, or MP4. A separate counterbore hole bridging setting adds partially bridged and sacrificial-layer options for counterbore or countersunk holes. One firm caveat remains: 3MF files saved in the beta are temporarily not supported for upload to MakerWorld. Bambu Lab has not published a stable-release date. Checked July 11, 2026.
The Assembly Guide is most relevant to makers documenting multi-part builds from STEP files. Counterbore bridging is a narrower but practical slicer option for functional parts. For a production workflow, the current stable build remains the lower-risk choice until the beta reaches a stable tag; the MakerWorld caveat is decisive if you publish 3MF projects there.

Source notes
The official release notes confirm STEP-based Assembly Guide steps, X-ray and current-step views, exploded-view animation, annotations, PDF/Markdown/MP4 export, and three counterbore bridging modes. They also warn that beta-saved 3MF files cannot currently be uploaded to MakerWorld. Confirm printer- and workflow-specific behavior against the current release notes before adopting the beta.
Decision context: This is a slicer beta, not a printer hardware release. Its clearest value is documenting complex assemblies and testing unsupported-hole strategies without manually building every instruction view. Stable-workflow reliability and MakerWorld publishing remain the reasons to wait.
- When will Bambu Studio 2.8.0 reach a stable tag and when will MakerWorld upload support be restored?
- How does the Assembly Guide handle assemblies with non-standard build order requirements or flexible components?
Stay on stable if: You publish designs to MakerWorld — stay on the stable release until the 3MF upload issue is resolved
Test the beta if: You design functional multi-part assemblies in STEP and want to test the assembly guide now

Frequently Asked Questions
Is Bambu Studio 2.8.0 a stable release?▼
No. It is a Public Beta available on GitHub. The stable release date has not been published. Use it to test the Assembly Guide and counterbore features, but do not save 3MF projects in the beta if you need to upload them to MakerWorld — that upload path is temporarily blocked in the beta version.
What is the Bambu Studio 2.8.0 Assembly Guide and who is it for?▼
It accepts STEP files and organizes a model into assembly steps, with X-ray and current-step-only views plus annotations and export options. It is most useful for makers documenting multi-part builds. The release notes do not describe STL support for this feature.
What should I check before installing Bambu Studio 2.8.0 Beta?▼
Confirm that your printer and workflow are covered by the current release notes, keep critical projects on the stable build, and avoid the beta if you need to upload beta-saved 3MF files to MakerWorld.
