The use of microCT of 10 mm coupon samples produced by AM has the potential to provide useful information of mean density and detailed porosity information of the interior of the samples. In addition. the same scan data can be used to provide surface roughness analysis of the as-built surfaces of the same coupon samples. This can be used to compare process parameters or new materials. https://www.roneverhart.com/1997-2005-BUICK-CENTURY-Engine-Starter-Motor-96K-Miles-3-1L-Sedan/
