Export

All models on the print bed and PrusaSlicer settings can be saved as a single 3MF Project file via the File -> Save Project as.

Alternatively, all models on the print bed can be exported as a single STL via File -> Export -> Export Plate as STL/OBJ.

You can also export individual models as an STL file. Right-click on any of the models in the 3D view and select Export as STL... This can be useful if you make changes to the model inside PrusaSlicer, such as cutting it. Note that depending on the modifications you made to the object, the other menu options might differ from the image below.

In the SLA mode, it’s also possible to include tree supports (as non-editable STL) via the  File -> Export -> Export Plate as STL/OBJ Including Supports.
