This article was prepared with AI assistance based on an analysis of the current Lumina Studio source code, existing Wiki content, and relevant workflows. It has been checked against the current version, but omissions or details that become outdated may remain as the software evolves. If you find an error or have a clearer explanation, example, or suggestion, please leave a comment on this page or propose an edit on GitHub.
Slicer and downloads
Lumina detects slicers it can launch and prioritises the application selected in Settings. The primary action depends on slicer availability, whether an artifact already exists, and Large Format state.
| State | Main-button action |
|---|---|
| Slicer detected, no artifact | Generate the 3MF, then open it in the selected slicer |
| Slicer detected, artifact ready | Open the current artifact directly |
| No slicer detected | Generate and download, or download the existing 3MF |
| Large Format | Generate or download a ZIP of tiled 3MF files; do not auto-open it |
The menu lists detected applications and provides a separate Download 3MF action. If the preferred application from Settings is missing, Lumina reports the mismatch instead of claiming a successful launch.
Final slicer checks
Verify the printer and nozzle, physical filament assignment, build-plate placement, display-face direction, and every fine feature or attachment in the sliced layers. A 3MF can carry model and material metadata, but the slicer makes the final machine-specific decisions.
