Dual Extrusion Slicing without manually created depth possible?

[Spark908 0]

Hello Makers. I'm having some issues slicing an object for dual extrusion. I am relatively new to dual extrusion and I'm trying to nail down the process for creating detailed meshes for 3d printing. I'm wondering if it is possible to slice an object for dual extrusion without solidifying or creating depth to the object. Is there a way for Cura to automatically create depth for an object like this? Every time I slice it, more than half  of the object is missing. It has many holes, many empty layers, and in general is just a mess. The objects are made using a separate by color, at the intersection of faces. They are near perfect opposites of each other to my knowledge. I'm not quite sure where I'm going wrong, but I'm hoping that I can create models like this without an extensive amount of manual editing.

In general I'm just looking to be able to import objects like this to Cura and have it recognize that infill should be printed on the inside of the object. Solidifying the object makes the shape successfully slice, but then the inside is hollow, and it prints it as a shell with no infill inside. Support as infill is a half baked solution for me. If I have sturdy supports inside, the supports created on the outside are difficult to remove. If I make the supports thinner and easy to remove, the supports on the inside might not hold up as well.

 

Thanks for your time, any and all help is appreciated. Dual extruding has been such a fun learning curve, I can't wait to nail the pipeline from imagination to reality with this stuff!
