I am looking for advice on 3D color printing using a Prusa (Slic3r). I’m able to make 3D models and print them just fine. No problem.
But I am struggling with Sketchup to produce color 3D printable models.
With Prusa you design separate STL files for each individual color. Basically it is a set of nested 3D models with each assigned to a separate extruder/tool/filament.
The difficulty with Sketchup that I am having is shared surfaces. A surface can be assigned to only ONE layer or be in only ONE group. So if two colored sections are adjacent, the shared wall can only be assigned to one of them. That leaves the other color without a surface on that side.
So what is the solution to this?
How can I create a model where the surface belongs to both colors?
