In 3D printing (and modeling, animation and more), objects are represented by their outer shell. This shell is represented as a triangle mesh. It’s possible to have several meshes inside a single file.
Sometimes this is done on purpose, for example, when you export the entire platter as a single STL or when you export a multi-material model. You may want to separate the shells in order to transform individual objects independently of each other or set different print settings for different models. PrusaSlicer can automatically identify multiple shells inside a single file and split them into separate models.
Select the model you wish to split and click either on Split to objects or Split to parts in the top toolbar.
Split to objects
- Creates an individual object for each shell
- Places each newly created object on the print bed
Split to parts
- Keeps a single model object in the scene, but creates multiple parts
- Parts stay in their original location, even if they’re floating in mid-air above the print bed
- Usually used to split MMU models without misaligning individual parts

In some figures you can see the holes where the loose parts should go but on smooth surfaces it is not easy to glue parts at the right spot.
I have a follow-up question though. This function creates an object with the name "Merged" that has unnamed parts in it. Is there a way to make it keep the names that the parts originally had? If not, perhaps it should be added in a future update. I like to have all my parts named in the 3mf files I publish, and it's pretty annoying to redo that manually every time, even though the files come from cad already named.
Did they remove it?
