Abstract

The component porosity is a quality attribute in additive manufacturing (AM). One way for a non-destructive
three-dimensional determination of the porosity or the shape of pores is X-ray computed tomography
(CT), which enables to investigate the influence of AM process parameters on the appearance
and characteristics of pores. Due to the lack of a porosity standard for CT, a traceable measurement
uncertainty determination is not possible. To investigate the capability of CT for porosity analysis,
measurements of an optically measurable glass specimen that contains highly spherical pores are used
to validate results from a digital twin of the CT system. The influence of a fixed gray value threshold for
the porosity analysis algorithm and the deviation of the surface determination are investigated.
