METHOD AND MACHINE FOR MAKING AT LEAST ONE ARTICLE MADE FROM AT LEAST ONE CERAMIC AND / OR METAL MATERIAL BY ADDITIVE PRODUCTION TECHNOLOGY Russian patent published in 2019 - IPC B33Y10/00 C04B35/622 B33Y30/00 B29C67/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to additive production technology and can be used for making ceramic or metal articles. A computer model of the article is constructed. Said product is formed on working tray by means of additive production from ceramic or metal photocurable composition (CPCb or MPCb). In compliance with this invention, at least one material other than said CPCb or MPCb is prepared, which is an ablative organic material (MOS) capable of being destructed by heating during the binder removal process, or an additional ceramic or metal composition of CPCa or MPCa; successive layers of CPCb or MPCb are formed, which are each time hardened by irradiation in accordance with a sample pre-determined from the model for said layer. To form hollow parts of part and / or to insert part of at least one part of other ceramic or metallic material into cavity of part, the following stages are performed: formation by treatment of at least one recess in at least one cured layer CPCb or MPCb from its upper surface; placing said at least one recess MOS, or CPCa, or MPCa for filling thereof; curing MOS, or CPCa, or MPCa, located in said at least one recess to produce solid horizontal surface at the same level as adjacent layer CPCb or MPCb. Molded part is subjected to operations of cleaning, removal of binder and sintering.

EFFECT: fabrication of articles of complex shape with cavities with possible arrangement in cavities of structures from other ceramic or metal material.
