Embodiments provide for partially cured, preformed pieces of PVA capable of later being formed into more specific models. The partially cured, pre-made pieces of PVA can take on many forms and shapes. For example, the shape may be a flat, tubular, cone, spherical, or other similar shape. In fact, more complex shapes such as full organs are also contemplated herein. Nevertheless, such pre-molded components are considered common or general shaped in that the particular shape is produced using standard or common molds, and then later formed into a more specific or desired shape. As such, the preformed pieces of PVA are only partially cured or cross-linked such that they can later be formed into the more specific models that then have additional processing (e.g., freeze-thaw cycle) to retain the new shape.
