We set the task of developing tools for operational control and diagnostics of the instability parameters of structurally heterogeneous properties of materials obtained by using discrete form-building technologies. Using the method of expert-analytical evaluation, we formulated functional-essential criteria characterizing the potential of various diagnostic methods.

We proposed a phased algorithm for realizing ultrasonic diagnostics in determining the variable anisotropy of the physical and mechanical properties of materials. The results of research of information-diagnostic possibilities of application of the expert-analytical analysis in the early stages of the life cycle of promising products are presented. As a result of the analysis, some results obtained by various technologies are presented, including discrete-additive laser sintering. And from the analysis of these data, a close correlation with the results of the performed EAA is seen, which confirms the scientific and applied significance of the study.
