Stereological transformation of pore size distributions with application to soft polymer and FDM‐printed specimens
Abstract: The presence of voids or cavities inside a material plays an important role in several applications. Recently, their investigation has gained attention to understand the effect of such inhomogeneities on 3D‐printed structures. Such structures could be already weakened due to the procedure of additive manufacturing. Voids can be visualized by computed tomography but practically a micrograph obtained by a planar cut through the material is simpler and cheaper. This requires, however, the reconstruction of the three‐dimensional distribution from statistical micrograph analyses. Here the reliability of such reconstruction is studied. To this end, spherical voids are considered whose size distribution can be characterized by one scalar number, e.g. the void radius. The corresponding distributions are typically positive right‐tailed, indicating more small than large voids. Following the work of S. D. Wicksell, the distributions of the observed planar cut are linked to the distribution of the spherical void size in space. The calculation of the stereological transformations is outlined in detail and several examples are provided to point on misleading conclusions. The presented analysis is applied to three typical soft‐polymer materials.
