The connection between the introduction of new technology based on the additive processes of metallurgy and mechanical engineering and the digital design technologies of cellular structures is shown. Examples of calculations are given. It is noted that in relation to the testing of cellular media obtained by the additive method, it is necessary to take into account the direction of the loads, which leads to the need to create anisotropic materials. When designing cellular media in the form of a combination of nodes and connections, it is necessary to take into account the possible concentration of stresses and, if possible, smooth out sharp transitions in such combinations.
