Title (EN) METHOD AND DEVICE FOR PRODUCING A SHAPED BODY
(FR) PROCEDE ET APPAREIL POUR PRODUIRE UN CORPS FAÇONNE
Abstract:
(EN) Method for producing a shaped body, which method comprises the following steps: (1) applying a layer of pulverulent material to a surface, (2) patternwise applying at least one liquid to the layer of pulverulent material, forming a layer of patternwise bound-together pulverulent material, (3) repeating steps (1) and (2) a predefined number of times, so that a number of successive layers of patternwise bound-together powder, is formed, the successive layers of bound-together pulverulent material together forming the shaped body, and (4) removing the unbound powder, in which the liquid comprises water and the pulverulent material comprises at least one component which forms a binder after contact with water in step (2).
(FR) On décrit un procédé de production d'un corps façonné qui consiste à: 1) appliquer une couche d'une matière pulvérulente sur une surface; 2) appliquer en motifs au moins un liquide sur une couche d'une matière pulvérulente pour former une couche de matière pulvérulente fixée en motifs; 3) répéter les étapes 1 et 2 un nombre préétabli de fois de manière à former un certain nombre de couches successives de poudre fixée en motifs, lesdites couches successives formant ensemble le corps façonné; et 4) éliminer la poudre non fixée, dans laquelle le liquide comprend de l'eau et la matière pulvérulente comprend au moins un élément formant un liant au contact de l'eau de l'étape 2.
