Abstract

La présente invention concerne, selon un mode de réalisation, un appareil et un procédé de fabrication de film de formation 3D comprenant les étapes suivantes : le façonnage d'un film de formation est effectué à une pression uniforme à l'aide d'un corps à volume variable et, par conséquent, il est possible de façonner des parties en contre-dépouille ; l'écart d'épaisseur d'un film de formation est réduit et ainsi la qualité d'un film de formation façonné en 3D est améliorée ; et lorsqu'un film ou une matrice de formation non certifié(e) est utilisé(e), le film ou la matrice de formation non certifié(e) peut être identifié(e). L'appareil de fabrication de film de formation 3D ayant une fonction d'identification de film de formation selon un mode de réalisation de la présente invention comprend : une matrice pour façonner un film de formation ; une unité de tête de presse conçue pour correspondre à la matrice et disposée à une distance variable de la matrice ; un corps à volume variable accouplé à l'unité de tête de presse, ayant une élasticité telle que son volume peut être changé en fonction de l'écoulement de fluide dans ou hors du corps par l'unité de tête de presse, et changeant son volume de façon à entrer en contact avec un film de formation placé dans la matrice et à presser le film de formation, ce qui permet de façonner le film de formation en une forme 3D ; et une unité d'analyse ultrasonore fournissant des ultrasons à travers le film de formation de façon à analyser le film de formation.
