The invention relates to a material of a three-dimensional framework of supporting, trabecular structures encompassing cavities which are connected with one another and which can be predeterminedly adjusted. The material is obtainable by forming the framework around the shaped bodies serving as space retainers for the cavities and subsequently removing the shaped bodies. The material according to the invention can be used for example as a implant or as a filter.

[ I claim:] [1.] A process for preparing a homogenous material, said process comprising the steps of:connecting essentially spherical-shaped bodies at their points of contact to form a three-dimensional shaped body conglomerate;forming a three-dimensional framework by casting or injecting a generally incompressible liquid material different from the shaped bodies around said connected shaped bodies, the material of the framework being selected from a group consisting of polymers, ceramics and metals;compressing the three-dimensional framework together with the shaped bodies; andafter at least partial hardening of the three-dimensional framework, removing the connected shaped bodies so that merely the polymer, ceramic or metallic three-dimensional framework remains in the form of the homogenous material.
