Abstract

L’invention concerne une méthode et une installation de fabrication additive pour pouvoir produire des pièces ébauchées (26) aptes à être frittées. Elle comprend les étapes suivantes : a) on superpose une pluralité de couches de particules d’un matériau pulvérulent ; b) on imprime un liant sur chacune des couches de particules dudit matériau pulvérulent de manière à lier entre elles des particules destinées à former lesdites pièces ébauchées (26), tandis que les particules non liées s’agrègent autour des particules liées en formant ensemble un seul bloc stratifié (28) ; et, c) on sépare lesdites particules non liées et lesdites particules liées dudit seul bloc stratifié (28). A l’étape c) on porte ledit seul bloc stratifié (26) en appui sur une grille (38) et en on soumet ledit seul bloc stratifié (26) aux ondes ultrasonores pour pouvoir désagréger lesdites particules non liées. Figure à publier avec l’abrégé : Fig. 5The invention relates to an additive manufacturing method and installation for producing blank parts (26) suitable for sintering. It comprises the following steps: a) a plurality of layers of particles of a powdery material are superimposed; b) a binder is printed on each of the layers of particles of said pulverulent material so as to bind together particles intended to form said rough parts (26), while the unbound particles aggregate around the bound particles, together forming a single laminated block (28); and, c) separating said unbound particles and said bound particles from said single laminated block (28). In step c) said single laminated block (26) is supported on a grid (38) and said single laminated block (26) is subjected to ultrasonic waves in order to be able to disintegrate said unbound particles. Figure to be published with the abstract: Fig. 5
