The problems of creating three-dimensional structures with a prescribed architecture based on pyrophosphate ceramic by the consumable additive method are studied. The problems of filling with a powder precursor the polymer negative printed in a 3D printer as well as preserving the structure of the material in the process of removing the polymer were solved. The processes of sintering of ceramic materials as well as the mechanical characteristics of the obtained materials are studied.
