PROCÉDÉ DE FABRICATION, PAR STÉRÉOLITHOGRAPHIE, DE PIÈCES CRUES EN MATÉRIAU CÉRAMIQUE OU MÉTALLIQUE PAR VOIE PHOTO-THERMIQUE
Disclosed is a method for manufacturing, by stereolithography, a green part made of a ceramic or metallic material. Layers based on a curable composition including: the ceramic or metallic material formed by at least one ceramic or metallic powder, respectively, and an organic part including at least one monomer and/or oligomer and at least one initiator for the polymerization of the one or more monomers and/or oligomers, are successively cured by the polymerization according to a pattern defined for each layer. The first layer formed on a construction platform, each other layer being formed and then cured on the preceding layer. As an initiator, at least one thermal initiator is used capable of generating the initiation of a thermal polymerization by the thermal energy released by the ceramic or metallic material, respectively, during exposure to at least one irradiation source chosen from UV, visible or IR irradiation sources.
