Abstract: This study was focused on laser forming of metal foam sandwich panels into non-Euclidean (3D) geometries. It was investigated whether the knowledge about the 2D bending mechanisms translates to 3D deformation, and whether the combination of process parameters that were identified for 2D laser forming are still appropriate. Moreover, the impact of the laser scan length was determined by comparing different scan patterns that achieve the same 3D geometries. It was shown that a significant amount of 3D deformation could be induced for both the bowl and saddle shapes, the two most fundamental non-Euclidean geometries. Furthermore, it was demonstrated that knowledge regarding the process parameter combinations and the bending mechanisms translates from 2D to 3D laser forming. The amount of bending deformation was shown to increase with the laser spot size, since in-plane strains start to be induced in the top facesheet.
