*STLC is used to assign a different volume fraction for the interfaces between parts. This is used to improve the modeling of support structure failure, by allowing users to specify the volume fraction of the support structure teeth, which is where support structure failure is modeled. The volume fractions will follow the order set in *STLM. Component STL files must be given an interface fraction even though the values will not be used.
