Internal "negative" object slicing?

Posted · Internal "negative" object slicing?

Hi all,

Ive modelled a hollow cylinder, and internally, I have a negative tube spiral  running inside the walls within the cylinder.

 

I cant seem to get Cura to slice the negative spiral. I have tried changing the wall thicknesses and infill density... all to no success.

I would like to know if there is a way that I can set cura to recognise an internal negative shape? Ideally printing completely solid and not printing the cut out tubed spiral within the walls?

 

Im hoping the screenshots of the blender file will help explain what Im hoping to achieve

Any help with this would be awesome!

Thanks with your help

    Hi @wez,

    most probably there's something wrong with the model. It is either not a solid body or it's a "non-manifold" mesh.

    One example: The protruding pipes seem to have no thickness at all? And there may be intersecting surfaces and such things...
    How was it modeled?
