Abstract

La présente invention décrit un appareil et un procédé d'usinage assisté par laser (LAM) d'un matériau osseux composite non monolithique. Un faisceau laser focalisé de haute intensité conduit l'élimination du matériau osseux sur une durée extrêmement courte sans provoquer de quelconque détérioration thermique (nécrose) ni mécanique au matériau entourant la région d'interaction os-laser. Un ordinateur associé à l'appareil d'usinage de l'os utilise préférablement une approche de modélisation informatisée Multiphysics qui prend en compte le phénomène physique tel que le transfert de chaleur, l'écoulement de liquide, le mélange par convection, et la tension superficielle lors de la détermination du volume cible de l'os, le calcul des propriétés du matériau osseux composite multicomposant et multicomposition, la détermination des paramètres d'usinage assisté par laser sur la base des propriétés du matériau, et l'exécution de la découpe/mise en forme/usinage assistés par laser de l'os.
