(FR) PROCEDE ET APPAREIL POUR PRODUIRE UN CORPS FACONNE
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).
