Aluminum foam sandwich panels were laser bent by means of a diode laser. Two panels different in thickness were used in bending tests; the effect of the main process parameters (laser power and scan velocity) on the bending efficiency was investigated as well as the contribution of the panel skin, and the protective gas. As a result, a very good formability was observed for the laser processed panels.
