Abstract

A filling method for filling surface imperfections on a surface of a wing comprising a scanning step in which a control unit controls a movement of a scanner past the surface of the wing to scan the surface and transmit the collected data to the control unit, a computation step in which the control unit computes a digitized surface from the data, a determination step in which the control unit determines each surface imperfection by comparing the reference surface and the digitized surface, a generation step in which the control unit generates a digital model of the patch intended to fill the surface imperfection, and a printing step in which the control unit controls the movement of a 3D printer past each surface imperfection and commands the activation of the 3D printer in order to make it print the patch.
