I’d like to suggest an important improvement to the Cut tool in Bambu Studio.
Current limitation:
The cut operation is based on an infinite plane, which always affects the entire model.
This makes it impossible to cut only a specific part of an object.
Example (see attached image):
I have a cylindrical shape with decorative petals on the outside.
I want to cut only the inner rim of the cylinder, without affecting the outer elements.
At the moment, this is not possible because the cut applies globally.
Suggested solution:
Introduce a scalable / bounded cut area instead of a full infinite plane.
For example:
a circular cut region (like a cylinder with adjustable diameter)
or a rectangular bounded cut zone
optionally movable and scalable in X/Y/Z
Benefits:
precise local edits directly in Bambu Studio
no need to use external tools like Blender or Meshmixer
faster workflow for modular and decorative models
especially useful for MakerWorld creators
This would be a huge upgrade for modeling flexibility inside Bambu Studio.
You can already use negative parts as cutting tools. Cylindrical and rectangular cuts are easily made from primitive shapes, or you can load a complex mesh (.stl) file as a cutting tool. If multiple objects are merged into one assembly, you can also right-click an object to make it negative with Change type.
Keeping the parts on both sides of the split may require loading the original model multiple times and using complementary cutting shapes.
This type of editing is pushing the boundaries of a slicer’s purpose. Such work is usually much easier and more precise when done in a dedicated design program.
Thanks a lot for the detailed explanation — I’ll definitely put it into practice!
That said, I still wish there was a more intuitive built-in feature, like a scalable/local cut tool, to make this process easier and faster.
Hi, I don’t have anything to add, but I’m curious from a developer perspective. In what situation(s) do you find it easier/faster to do modeling operations in the slicer? Is it some one-time operation where all you have is the mesh of a model to work with? (Like to fit a published model to a smaller build plate, for example.) Or something else?
Think of the cut operation being based on an infinite sized box, not a plane. Everything inside the box is removed with a Boolean subtract operation.
In that context, a non-infinite cut operator is going to be a box primitive with a finite size. Same as the box primitive you’d make yourself to do a Boolean subtract to slice away a part of your model.
So you essentially already have exactly what you want. If BBL implemented a dedicated feature, it’d basically be the exact same thing - a finite sized box that takes a bite out of your STL.
