چکیده انگلیسی
This study focuses on the comparison of porosity testing methods for the quality assessment of selective laser melted parts. Porosity is regarded as important quality indicator in metal additive manufacturing. Various destructive and non-destructive testing methods are compared, ranging from global to local observation techniques and from quick low-cost to expensive time-consuming analyses. Forty test specimens were produced using five varying control factors. The experimental results show that Archimedes and CT methods compare well, Archimedes can be deployed to inspect parts in small series and CT pre- and post-cut analysis show that post-cut porosity results are systematically higher.
