MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
That is the problem isn't it? How do I create a model and only print part of it to the STL or OBJ file? In my CAD program I suppose that I could create a whole model, then edit out... Hmm. I can see how that is done.
But, for the more creative models (like your frog) I don't have tools to render those, is that a "Blender" type of job? I have no exposure to those tool sets yet.
In some ways, Simplify3D can do this as well by creating two processes, one for each of the stl files. They print them at the same time.
Hmm. Fun! I have "normal" printing down, this is taking it to the next level.
