Design and development of equipment for post-processing of products manufactured using additive manufacturing technologies

The results of a study of the influence of the parameters of selective laser sintering of metal powders and cold isostatic pressing of samples from a high-chromium heat-resistant alloy on the size, number of pores, and microstructure of the alloy are shown. It is shown that, in SLS alloys, the use of cold isostatic pressing makes it possible to reduce the number and size of pores. The strengthening effect is found, which manifests itself in an increase in the hardness of the surface layer at room temperature of deformation.
