Hello Rob, FreeCAD is nice for modeling 3D shapes.
Not if you've ever used a commercial product that does the same job. ;)
For 3D printing, depending on the technology of 3D printer, you need to process original model to convert compact sections into hollow honeycomb structure, and add small plastic bars into empty volumes to support the model while it's printed. I'm not expert of this latter procedure and tools.
Dictating the infill pattern of a STL file is *never* the job of the drawing tool, it's the job of the slicer being used to turn the STL file into gcode.
