I am having a problem trying to remove a negative part from an object in “Prepare” mode and exporting it as an stl with the negative part removed. I can slice it and it removes the negative part but then you cannot export as an stl. The reason I want to do this is because I want to cut the hole (negative cylinder) through my object. Export it as an stl and then re-import it to make it a negative part so that I can extract it from a sliced casting block with connectors. Any ideas?
I’m a fan of Tinkercad for things like this. Import the original, have at it with negative parts (Tinkercad calls them holes) then export the results as a STL. It’s free but you do have to sign in. And I find it way more user friendly than the slicer for modifications.

Yep thanks for you idea. I use Fusion360 and Meshmixer but it was only because BL is so easy to use that I wondered if it was achievable. Evidently not. I have done it in Meshmixer as it is very simple when you have sussed it out.
Do not use negative part, as these are only reflected at slice time (as you experienced).
If you want to export an STL reflecting the minus part and to do that directly in Bambu Studio:
- Make an assembly of the parts you want to remove from each other.
- Select the assembly and click ‘Mesh Bolean’ from the top icon bar.
- Select ‘Difference’ and choose your part you want to delete from and the part you want to subtract with. Check ‘Delete Input’.
- Now you can export that part as STL.
You may experience STL errors with the exported STL sometimes, but usually recoverable.
See an example where I use the arc of a cylinder to be a negative part on a cube. See the assembly and the boolean mesh. Exported to cubediff.stl and imported again.
Hope this helps.
