solidification rate was not uniform along the printed wall, as confirmed by the observation of fine cellular structure at the bottom zone and a columnar coarse grain structure at the topmost region. The hardness reduction from the bottom towards the top region also reflects this fact in terms of decrease in mechanical properties from the bottom to the top of the build.
