Since the discovery of porous metallic materials numerous methods of production have been developed. Porous metallic materials can be made from liquid metal, from powdered metal, metal vapours, or from metal ions. The aim of the paper is to introduce casting methods of manufacturing of metallic foams with irregular cell structure. Metallic foams are materials with the broad applicability in many different areas (e.g. automotive industry, building industry, medicine, etc.). These metallic materials have specific properties, such as large rigidity at low density, high thermal conductivity, capability to absorb energy, etc.Keywords: casting, metallic foam, irregular cell structure, investment casting, precursor
