METHOD OF MAKING PARTS MADE FROM CERAMIC MATERIAL BY ADDITIVE PRODUCTION TECHNOLOGY Russian patent published in 2019 - IPC C04B35/00 B29C64/10 B33Y10/00 

FIELD: ceramics.

SUBSTANCE: invention relates to production of parts from ceramic material using additive or stereolithographic techniques. Disclosed is a method of making a part, in which part is formed in a crude state from a photocurable ceramic composition. Method includes the following stages: on a working platform of a stereolithographic machine, is produced by means of an additive production technique simultaneously, but separately from the same paste-like photocurable ceramic composition: raw assembly consisting of support of raw part and raw part on support, free surface of latter has imprint of first surface of raw part; and a crude mold made of a part made from ceramic material, the free surface of which has an imprint of the second surface of the raw part opposite to the first surface; into the furnace on the raw mold, thus obtained, with an unfolded print, placing said raw assembly, obtained in this way with its raw part, turned down, so that it could fit into the imprint of the formatter, and a wet part, thus retained between the mold and the support, where the part is subjected to binder removal and sintering.

EFFECT: technical result is ensuring prevention of any deformation of parts during production, cleaning and firing.
