This growth is due to the many benefits offered by this process compared to the conventional manufacturing methods. However, LPBF, by its nature, causes the appearance of specific processing-induced flaws that affect the mechanical properties of parts produced, thus limiting their industrial use Among these defects, porosity is <\/span><span class=\"NormalTextRun AdvancedProofingIssueV2Themed SCXW84828080 BCX0\">particular since<\/span><span class=\"NormalTextRun SCXW84828080 BCX0\"> it cannot be completely <\/span><span class=\"NormalTextRun ContextualSpellingAndGrammarErrorV2Themed GrammarErrorHighlight SCXW84828080 BCX0\">eliminated<\/span><span class=\"NormalTextRun SCXW84828080 BCX0\"> and its detection is difficult and costly.
