The article deals with casting methods of producing of metallic foams, it is focused on materials with a regular arrangement of internal cells. Currently, there are two areas dealing with metallic foams: optimization of already used casting technologies - manufacturing of metallic foams with a regular cell structure using sand cores and the possibility of the usage of this material. Cast metallic foams have a wide range of applications such as: construction, transport, heat exchangers etc. for their outstanding properties: reduced weight sufficient strength to absorb the impact energy or the possibility of heat conduction.Keywords: Metal foam, mechanical testing, energy absorption, 3D modelling, heat exchanger
