This paper aims at presenting the main processing routes that are used to produce foams in their general definition and the typical structure that can be obtained according to the process. We first describe the main classification of the foam according to the level of porosity (open cells, closed cells, partially open cells and mixed cells). We present briefly the main processes to obtain such structures (non-removable space holder stacking and impregnation, removable space holder, foaming from gas or from precursor and shortly additive manufacturing) with a specific focus on the metal foam processing. We finally indicate the main structure that can be obtained with these types of processes and the main characteristics that are necessary to quantify at the various scale of the structure.
