(in lingua inglese)
It has been shown that a very specific type of layered defect can be formed in laser AM metal parts, most likely due to imperfect melting in specific layers. These defects are present in a part with as little as 0.005% porosity, but can still be a problem if localized in a thin walled section and is hence of importance in material studies and non-destructive testing of high-performance parts. X-ray microCT seems to be the ideal tool to characterize this type of defect due to the defect size and geometry, though X-ray microCT could also be used to indicate where to physically section a sample for further analysis.
