Five years ago Fraunhofer-IWU started research in open cellular structures as the market is growing caused by their large surface. Heat exchangers, filters and battery electrodes are examples for potential applications. Casted Aluminum foams are in serial production and we cooperate with the manufacturer but for prototyping of individual foams especially in combination with solid regions for fixing, encasing or sub-division new parameters and technological processes were developed. Advantageous, limitations and potentials will be shown. Alternatively, galvanic coating of PUR foams with Copper, Nickel and other metals is common, again buyable and state of the art. R&D activities related to application development and adapted geometries not yet realizable by conventional mass production will be shown. Investigations for graded strut-structures and cylindrical tube-like parts were intensified to reach serial production level. The lecture represents investigations, results, dropped and new approaches of all routes.
