Back to the old days, there were several applications of this feature.
1. Molecular models. Identifying different atom types by different shapes
and sizes of the fillers (wax voids trapped in the plastic spheres
["atoms"]).
2. Grey level. A grid of voids, uniformly positioned but varying in void sizes
was used for generating a grey-level "picture" on the boundary of the model.
3. Business cards. Flat plastic "business cards" contained the owner's name
and details written in engraved voids filled with wax. (The "font" however
was quite ugly.)
4. Assembly marks. Huge models were broken into several pieces with wax-filled
voids serving as assembly marks.
5. Blood. There was a blood-vessels model (data obtained by an MRI scanner),
where the (blue) wax indicated the blood and the (light-yellow) plastic
formed the vessels.
Etc. Etc.
Cubital also organized a workshop on heterogeneous models during March 1993.
Proceedings are available (so I assume; at least I have a copy) from their
p.r. people.
