(a) Port opening with centered channel for a resistance component with 642.5 μm cross-sectional side length showing the precision in the print plane, xy, and the precision in the print axis, z. Due to the control mechanisms of stereolithography, precision in the xy and z plane are expected to be different. (b) Total component resistance was approximated by determining and adding together the resistance of segments respective to the xy-planes (yellow lines) and z-plane (purple lines). Both planes carry a particular fabrication error, determined by optically measuring the cross-sectional side length of components and creating distributions of precisions in both orientations (see Supplementary Figure 1).
