Abstract

The rapidly developing field of additive manufacturing requires quality control of finished products. In this regard, nondestructive testing methods, in particular X-ray computed microtomography, turned out to be in demand. The paper presents a study of the structure of the ZrO2–20%Al2O3 ceramic composite obtained by the fused deposition modeling method of a thermoplastic suspension consisting of nanostructured powders of the same composition, a binder, and carbon nanotubes. To obtain information about the structure, two-dimensional sections of reconstructed images were analyzed. The anisotropy of the structure was shown, and possible causes of the heterogeneity of the pore and grain structure were explained. The information about the structure obtained by X-ray computed tomography will be used in further work to optimize the parameters of the fused deposition modeling technology and optimize the compositions of thermoplastic suspensions.
