[Trommelschlumpf 1]

Hi,

I would like to print this parts:

FreeCad shows this parts as they should be:

 

But Cura places an infill:

 

 

Which setting might I want to change?

 

Also Id like to print one single of those parts. Is there an option I can cut the rest away?

The part is defective.  I know it looks fine in freecad but it's not fine.  Since it isn't your part I recommend you try netfabb repair.

 

netfabb free repair service is here (you have to create a free account first):

As far as splitting it up - Cura did that back in version 16.X but not anymore.  Freecad should be able to do that but I don't know freecad very well.  meshmixer (also free) might be easier.  Try googling this subject.  meshmixer might also have some model repair features.

I finally found "mesh fixes" "remove all holes" in cure - disabling this everything looks fine 😉

If that's all it takes then it's probably just the "normals" are backwards in a portion of the print.   STL file contains unordered triangles and each triangle has "normal" with it to say which side of the triangle faces air and which side faces plastic.

No, if the "Remove all holes" option was enabled, then Cura did exactly what it was instructed to do, and the model was likely just fine.

Exactly, slicing works fine now 😉
