METHOD AND MACHINE FOR MANUFACTURING PIECES MADE OF CERAMIC OR METALLIC MATERIAL BY THE TECHNIQUE OF ADDITIVE MANUFACTURING
The disclosed method includes selecting a suspension ceramic or metal photocurable composition (CPC or MPC); preparing a sacrificial organic material (SOM) forming a photocurable layer destroyed by heating; for manufacturing pieces, on the working tray, forming successive layers of SOM cured by irradiation, the one or more CPC or MPC-based pieces being manufactured by machining a recess in a layer of cured SOM; depositing the CPC or MPC within the recesses; curing the CPC or MPC to obtain a hard horizontal surface level with the adjacent layer of cured SOM, when forming each recess, it is delimited by previously defined patterns, the depth(s) selected in order to ensure the continuity of the one or more pieces to be manufactured; and obtaining one or more green pieces inserted in the SOM, which are subjected to debinding by heating in order to destroy the SOM in which they are trapped.
