METHOD AND MACHINE FOR PRODUCING AT LEAST ONE PART IN AT LEAST ONE CERAMIC AND/OR METAL MATERIAL BY ADDITIVE MANUFACTURING
A computer model of the at least one piece to be manufactured is built up by computer-aided design; on a working tray, the piece is formed from a ceramic or metallic photocurable composition. At least one sacrificial organic material different from the basic CPCb or MPCb is prepared; successive CPCb...

| description | A computer model of the at least one piece to be manufactured is built up by computer-aided design; on a working tray, the piece is formed from a ceramic or metallic photocurable composition. At least one sacrificial organic material different from the basic CPCb or MPCb is prepared; successive CPCb or MPCb layers are formed, the following steps being carried out to form hollow parts of the piece and/or to insert at least one part into another ceramic or metallic material: forming a recess in a cured CPCb or MPCb layer from the upper surface thereof; depositing in the recess a MOS or CPCa or MPCa to fill; curing the MOS or CPCa or MPCa in the recess to obtain a hard horizontal surface at the same level as the nearby CPCb or MPCb layer. |
