“…Nowadays, with 3D printing one can replicate the diversified geometry encountered in a soil at a resolution of few micrometres. However, only a few studies have shown the potential of using 3D prints to better understand physical, mechanical or biological processes in soils (Dal Ferro & Morari, 2015; Otten et al, 2012; Ozelim & Cavalcante, 2019; Wang et al, 2017). X‐ray CT imaging of 3D printed structures using different printing techniques revealed imperfections, such as clogging of parts of the pore space by printing material residues or printing‐aid material, which would introduce artefacts into the physical functioning (Bacher, Schwen, & Koestel, 2015; Dal Ferro & Morari, 2015; Watson et al, 2019).…”
