Systems of multilevel organized structures are proposed for examining ceramic products with a periodic topology. Structural changes on various scales were studied in corundum ceramics produced by 3D-printing during annealing at 1700°C. Changes of the body geometry, layer structure of the printed sample, material grain structure, and α-Al2O3 grain crystal lattice constants were characterized.
