The results of experiments on the use of additive 3D printing technology by the method of selective laser melting for the manufacture of cellular structures for medical purposes are presented. With the help of electron microscopy, the architecture of the cellular material was revealed, and the geometrical parameters of the structure were measured. It is shown that increasing the radiation power when using selective laser melting leads to an increase in the density of the material, an excess of radiation power can lead to a violation of the product geometry, which should be avoided when making complex structural compositions.
