# Analysis of Building Platform Inhomogeneities in PBF-LB/M Process on Alloy 718
## Appendix A  
The appendix shows the data used for the paper; in particular, in Table A1 the data obtained as regards the track stability level as a function of Differential Pressure, Position and Exposed Area are reported; in Table A2, the data of Porosity and in Table A3 the analysis of the Melt Pool Depth and Width are given. \begin{table}
\begin{tabular}{c c c c} \hline \hline
