Detecting and Compensating for an Anomaly in Three-Dimensional Object Fabrication

Described herein is a system and method for detecting and compensating for an anomaly in three-dimensional object fabrication. A wall thickness computation component computes a wall thickness of a three-dimensional object to be fabricated. An edge map generation component generates an edge map for one or more portions of the three-dimensional object to be fabricated satisfying one or more wall thickness criteria. The wall thickness criteria includes, for example, a computed wall thickness less than an extrusion width of a fabrication apparatus, a computed wall thickness greater than an extrusion width and less than twice the extrusion width and/or a computed wall thickness not an integer multiple of the extrusion width. A tool path generation component generates a tool path based on the generated edge map.
