change filling factor in some regions

Hi everybody, how do you solve this type of problems:
I have a pedestal and a thin object coming out on sharp angle (for example a leg). I am printing with low infill.
Simplify3D algorithm makes the interface between pedestal and object using infill. Which is correct, but very weak and frequently broken.
So it would be cool to say to software to make solid fill around the area. But such an option does not exist - what would you do ?
Thanx!

The most common way to have different infill densities for different parts is to differentiate by layer. I don't think any current slicer allows you to set arbitrary densitives for different 3D areas.

Slic3r will allow you to set arbitrary settings for specified areas. you do this by applying a Mesh Modifier.
-take your STL into a CAD software
-add an accompaning volume that describes the region that would follow a different set of rules
-in slicer, double click on the STL in question, load the modifier mesh and set the specific settings.

and finally the result:
- End result of applying the modifier mesh

I think you can do that in S3D as well, by portioning the design into parts before printing, and then assigning different Processes to each part. (No I've never tried it....jin could probably walk you through it.)
