Industrial tomography (XCT) is a nondestructive test method that provides information
about spatial distribution of X-ray absorption in the analyzed structures. The aim of this
paper was to examine the possibility and accuracy of application of XCT method for
discontinuity and porosity detection in parts made of 316L stainless steel powder produced
by Selective Laser Melting technology. Analysis conducted on three produced test samples
showed that the application of XCT as a method of quality control of specimens produced
with an additive manufacturing technology offers a wide range of possibilities to detect
porosity within materials. Parameters such as the amount of porosity, pore size and
pore shape are presented. Accuracy of XCT method strongly depends on the size of the
samples analyzed, but the possibility of obtaining information in 3D nondestructively shows
considerable advantages of XCT method over traditional metallographic cross-sectional
analysis.
