(A) The planned (black line) and the measured Cerrobend outlines (blue line) have a mean deviation of 2.6±0.2 mm. Even after shifting, the Cerrobend outline (dashed line) shows a maximum deviation of 2 mm and a mean of 0.8 mm compared to the planned outline. (B) The 3D printed cutout (blue line) follows the planned outline (black line) more closely with maximum deviation of 1 mm and a mean of 0.4 mm. (C) Histogram of deviations between final and planned field shapes.
