1. A system for automated metrology, measurement, and model correction of a three dimensional (3D) model for 3D printability, said system comprising: at least one processor configured to: receive or generate slices of the 3D model, the slices representing two dimensional (2D) solids of the 3D model to be printed in corresponding print layers; calculate medial axis transforms of the slices, the medial axis transforms representing the slices in terms of corresponding medial axes; and determine a local feature size at any point along a boundary of the slices as the shortest distance from the point to a corresponding medial axis.
