METHOD AND MACHINE FOR PRODUCTION OF RAW ARTICLES FROM CERAMIC AND/OR METAL MATERIAL BY ADDITIVE PRODUCTION TECHNOLOGY Russian patent published in 2019 - IPC C04B35/622 B33Y30/00 B28B13/00 

FIELD: chemistry.

SUBSTANCE: invention relates to production of raw articles from ceramic or metal material from photocurable composition by additive production. According to the invention, before the first layer is produced, working tray (3) is coated with support sheet (9), which is pressed to it, forming a rigid and fixed surface for receiving successive layers, and which is capable of retaining successive applied layers, which form raw article (10) by additive production technology. After application of all layers, pressing is stopped to separate said support sheet (9) from said tray (3), on which raw article (10) is located with part of photocurable composition which has not been cured. Uncured part of the photocurable composition is removed and the crude article is removed from support sheet (9). Support plate clamp to the tray is performed by means of vacuum suction or magnetic force.

EFFECT: technical result of invention is reliable retention of article on rigid tray during layer laying and removal of molded article from tray without damages.
