Granulometric Analysis of Powder Materials Used for Producing Samples by Method of Selective Laser Melting

摘要

The paper discusses the aspects of granulometric and morphological analysis of powders used in the technology of selective laser melting. Studies have been carried out to obtain statistical data concerning the particle size distribution, as well as their integral and differential distribution. The aspects of independent significance in this work had to do with identifying the morphological features of the particles. Experimental studies were carried out using certified and validated equipment. Conclusions were drawn about the specific features of the analyzed powders, and directions for further research were proposed, including the formation of databases of powder materials, which can be of value to process engineers who use additive technologies in practice.
