Abstract: The invention concerns a method for additive manufacturing a component by repetitively superposing and solidifying material layers according to a 3D model of the component. The method comprises the steps of scan, by means of an eddy current sensing unit (20), of a new solidified cross section (15) obtained by selectively solidifying a material layer so as to provide an integrity data (VMM) of a sensed portion (23). A difference between the sensed integrity data (VMM) and an expected integrity data (VEE) is then executed for detecting a manufacturing anomaly within this portion. The expected integrity data (VEE) is determined based on collected integrity data of a solid basic structure likely matching or being identical to a geometrical structure (41) obtained from the 3D model (40) of a portion corresponding to said sensed portion (23), said solid basic structure being manufactured or simulated according to another 3D model.
