Effect of three different smoothing levels and slice thickness on the DEE. The heat maps indicate the deviation be-tween direct segmentation results and print-STLs according to the legend on the right. first row: effect of different smoothing levels for a given slice thickness of the underlying DICOM data set and software 3D Slicer. Second and third row: effect of different slice thicknesses of the underlying DICOM data set on the DEE for a given smoothing level (medium). Note that in D2P only a low level of smoothing with a minimal effect is available
