A MOLD FOR MAKING A THREE-DIMENSIONAL COMPLEX STRUCTURE, SAID MOLD COMPRISING AT LEAST THREE MOLD PORTIONS, METHOD OF MAKING SAID MOLD, AND USE OF SAID MOLD FOR MAKING THREE-DIMENSIONAL COMPLEX STRUCTURES

摘要

Molds, methods of forming the molds, and methods of using the molds to form complex unitary three-dimensional structures are provided. The complex unitary three-dimensional structures and its complement have a high degree of interlocking. The molds include at least three mold portions constructed and arranged to include a complement of complex three-dimensional unitary structure when in an assembled configuration, and a portion of the complement when in an unassembled configuration. The structure is not removable from the mold portions without destroying at least a portion of the mold. The method involves providing a mold that includes a complement of the complex unitary three-dimensional structure, introducing a fluid material into the mold, and removing the complex unitary three-dimensional structure from the mold.
