On the Development of a Universal Calculation Method for Assessing the Degradation of Recycled Metal Powder Materials, Depending on the Cyclicity of Use in the Selective Laser Melting Process

Abstract

This article analyses foreign articles on the influence of the frequency of use on the level of impurities, technological characteristics of the powder in the SLM (DMLS) process and on the mechanical properties of the synthesized materials. A solution to the problem of developing a universal calculation method for evaluating degradation in the SLM process of recycled metal powder materials has been proposed. The algorithm includes the automatic correlation of the contamination factors with the corresponding exposure mode elements of each type of cross-section (contour, upskin, downskin, core) during measurement of the longitude of the laser path or the exposure duration of all elements that form the cross-section of a part.
