Abstract
In in-process inspection or calibration of a print bed or 3D printed part with a 3D printer, toolpaths defining printing material shells for deposition by a 3D printer are compared to surface profile scans from a range scanner to identify differences between the print bed, instructed deposition and the measured result, permitting pausing or alteration of the toolpaths or printing process.
