Method and apparatus for manufacturing three-dimensional objects (W) consisting of superimposed layers (L) of a base material (M), liquid at ambient temperature and capable of solidifying permanently following a stimulating action. The method comprises the following operations: spreading a layer (L1) of the liquid base material (M) on the preceding layer (L), se-lectively exposing the layer (L1) to stimulation in one or more predefined areas (K), repeating the spreading operation and the ex-posure for each successive layer of the three-dimensional object (W), cooling the layers (L) to a predefined operating temperature below ambient temperature before the stimulation, in order to make the base material (M) solidify.
Linvention concerne un procédé de fabrication dobjets en trois dimensions (W) constitués de couches superposées (L) dun matériau de base (M), liquide à température ambiante et capable de se solidifier de façon permanente à la suite dune action de stimulation, et comprenant les opérations suivantes : application dune couche (L1) de matériau de base (M) liquide sur la couche précédente (L), exposition de manière sélective de la couche (L1) à la stimulation dans une ou plusieurs zones prédéterminées (K), répétition des opérations dapplication de couche et dexposition pour chaque couche successive de lobjet en trois dimensions (W), refroidissement des couches (L) jusquà une température opérationnelle prédéterminée, inférieure à la température ambiante avant la stimulation, afin dobtenir la solidification du matériau de base (M).
