Abstract
A process for direct fabrication of a part at a predetermined structural position. The process comprises: a) scanning, via a three-dimensional scanner, the structure in the region of the predetermined position; b) comparing a virtual surface mesh of the predetermined position with a real surface mesh of the predetermined position, the real surface mesh calculated based on data obtained from the scanning; c) determining the gaps between the two meshes; d) calculating the data for modeling an inserted part, the dimensions of which fill up the determined gaps, to obtain an inserted part model; e) merging of a virtual model of a part, linked with the predetermined position, with the inserted part model, to obtain a model adjusted to the geometry of the structure in the region of the predetermined position; f) fabricating, by material deposition, an adjusted part at the predetermined position based on the adjusted model.
