FOAM SCAFFOLD MATERIALS

摘要

A foam structure comprising a scaffold material including a predetermined repeating arrangement of polyhedral modules may have shapes of truncated octahedra, Kelvin minimal surface tetrakaidecahedra, or other polyhedral shapes. The foam may be open-cell, in which the polyhedral modules are formed of elongated members defining their edges, or closed-cell, in which the polyhedral modules are formed of substantially planar members defining their faces. The foam can be formed by computer-aided manufacturing techniques, self-assembly techniques, or lost core molding techniques. With this arrangement, a variety of idealized foam material shapes and sizes can be provided, for use in a variety of applications. In addition, the foam material can be designed to be multi-functional and to provide mechanical load-bearing along with other desired properties as required.
