Fast prototyping process for the production of industrial parts by transformation of successive volumes of raw material from a first status to a second status by means of a transformation inducing device, said transformation being followed by a covering phase using at least one scraper, the scraper or scrapers (12a-12e) impeding, at a given time, the device from producing transformations in at least one of the portions of a working field (11) by generating a shadow effect, characterized in that at least at a given time t of a given cycle, the device is caused to produce a transformation in at least one zone of the working field (11) inside its portion delimited by the continuous, close and smaller contour containing all of its points concerned by the shadow effect at the time considered, the displacement of the scraper or scrapers being such that the shadow effect frees at least partially the shadow zone at the considered time t, a succession of transformations and displacements of the scraper or scrapers taking place in order to achieve the considered cycle.
