“…Considering the five types of structures (SP1 to SP5), on average, the open-cell sizes are ≈105 μm lower and the wall sizes are ≈99 μm higher comparing to the model CAD dimensions. In fact, it is important to highlight that these deviations were found for all the investigated structures indicating that these dissimilarities are inherent to SLM technique, as reported in several studies (Arabnejad et al, 2016;Bartolomeu et al, 2017bBartolomeu et al, , 2019bBartolomeu et al, , 2020aRan et al, 2018). In literature several studies can be found indicating that the fabrication of sub-millimetric porous structures by SLM leads to ≈100 μm smaller open-cells and ≈100 μm thicker walls (Bagheri et al, 2017;Yan et al, 2012;Arabnejad et al, 2016;Dallago et al, 2019b).…”
