Fig. 11.9 Silicone mould, for subsequent casting of biomaterials. The different cavities reproduce
the geometry of scaffolds with fractal surface for promoting cell growth and differentiation
so as to avoid sudden solidifi cation upon contact of the wax with a cold surface,
what would prevent the different cavities from fi lling correctly. The level of detail
can be appreciated by having a look at the bottom image of Fig. 11.10 .
The possibility of obtaining wax replicas of different rapid prototypes, even
through the use of a second-phase process, is remarkable indeed, not just for
using wax parts in biomedical applications (as it is a biomaterial) but also for
obtaining metallic parts/prototypes. For improved production, a wax tree, to
