The invention relates to a method for producing a metal foam body according , to which a molten material containing gas is prepared and said molten material is left to solidify, thus forming a metal foam body. The aim of the invention is to produce high-quality metal foam bodies with a desired shape without , requiring complex equipment and whilst reducing the safety risk for the operating personnel. To achieve this, the material used is fused under atmospheric pressure and gas is simultaneously and/or subsequently introduced into the molten metal. The latter is then poured into a mould and is left to solidify, whereby the ambient pressure is reduced at least temporarily.
