As can be seen in Fig. 10, there is a nominal G-code toolpath created by a slicing software (blue line) that represents the centerline of the nozzle trajectory. In addition to this, there is a oval rectangular shape that shows the actual filament cross section that has been verified geometrically.

Geometrical comparison The Python-based shape generator demonstrates efficient computational performance with linear scaling relative to geometric complexity. Benchmark testing on models of increasing complexity revealed that geometry generation time increases proportionally to the number of toolpath segments.
