boolean mesh does not work correctly #3508

Printer

Bambu LAB P1S

How to reproduce

I create objects in the Bambu LAB Studio that I want to combine using the "Boolean Mesh" function. This also usually works with the first objects (including negative objects). But as soon as I try to use this function more often, I get an error message.

Actual results

Error:

A Boolean operation cannot be performed on model meshes. Only positive parts are exported.

Expected results

All Boolean operations must be carried out because the printer converts the object correctly and the printer also prints the object correctly.

The 3mf file you uploaded has only one part and can't do boolean. Did you upload the wrong file?

Sorry, it was the wrong file. Now it should be the right one.

I added a little more message about the failure reason and here is the result. It seems your input mesh has self-intersection and can't do boolean. image

You can use MeshLab to view the self-intersected faces: image

Thanks for the help, I'll try it out.

Gentle-Camper commented 7 months ago

I tried it, but that's not the problem. I have a positive object and then want to subtract a negative object. Then combine these with a Boolean mesh. This works sometimes and not always. In the image you sent me, the negative object was simply left out.

@Gentle-Camper Mesh boolean has stronger requirements of object meshes than slicing. If one of your objects, either positive or negative, has self-intersection, boolean can't be done. In this case, the positive object has self-intersection - the fonts are just attached to the cylinder but not fused. Self-intersection is difficult to resolve. I'm not giving a solution - there is nothing we can do now. You'll need to re-design your object mesh.
