Batch Export - Complete Documentation¶

The DAMTools Batch Export tool allows exporting all selected objects as individual STL files to the last folder used for import, facilitating organization and workflow in 3D printing, engineering, and mass modeling projects.

What is Batch Export?¶

It allows exporting all selected objects as individual STL files, using the last import folder as the destination. Each object is exported with a safe and unique name, and the selection/active object are restored upon completion.

Workflow¶

Select the objects to export (MESH type).
Open the DAMTools sidebar panel (N Panel).
Go to the "Quick Export (STL)" section.
Press "Export Selection as STL".
Each object is exported as STL to the last import folder.

Options and Parameters¶

Destination folder: The last folder used for importing files is used.
Selection: Only selected MESH type objects are exported.
Safe filenames: STL files are automatically named safely.

Shortcuts and Access¶

DAMTools Sidebar Panel: "Quick Export (STL)" section.
DAMTools Pie Menu (Shift+W): "Export STL" option.
Operator: object.batch_export_stl_last_dir

Functionality Explanation¶

Individual Export per Object¶

Each selected object is exported as an independent STL file.
The filename is automatically generated from the object's name.

Selection and Active Restoration¶

After the export finishes, the original selection and active object are restored to avoid interrupting the workflow.

Safe Filenames¶

A sanitization function is used to prevent invalid characters in filenames.

Key Code Snippets¶

Exporting Each Object¶

for i, obj in enumerate(selected_objects):
    # ...
    clean_name = sanitize_filename(obj.name)
    filepath = os.path.join(output_directory, clean_name + ".stl")
    bpy.ops.export_mesh.stl(filepath=filepath, use_selection=True)

Selection and Active Restoration¶

# Restore original selection after exporting
bpy.ops.object.select_all(action='DESELECT')
for obj_name in original_selection_names:
    obj_in_scene = bpy.data.objects.get(obj_name)
    if obj_in_scene and obj_in_scene.name in context.view_layer.objects:
        obj_in_scene.select_set(True)
# Restore original active object
if original_active and original_active.name in context.view_layer.objects:
    context.view_layer.objects.active = original_active
