CAD problems and Swiss Cheese

Can anyone help

We are doing some research at Liverpool which involves the generation of a plastic structure made up from small interlinked balls. We have a CAD solid model of the geometry but we need to turn the geometry into the inverse of Swiss Cheese!!!! and subsequently manufacture it on out SLS machine. The route I have used so far is as follows

1. Create the geometry on UG
2. Create an array of interlinked spheres
3. Intersect the two solid models

Unfortunately because there are so many balls my machine (SG octane) keeps killing the application which is unfair to say the least. Can anyone help,does anyone know of a structure like Quick Cast for example which does not have the outer skin and can be automatically generated?

Thanks
