Research questionHow can multi-axis printers generate collision-free toolpaths directly from non-manifold and non-watertight models?Real-world models may combine shells and solids or contain non-manifold and non-watertight structures. Repairing them can be time-consuming and may alter the intended geometry, while the printer still needs a usable spatial toolpath and collision-free motion.
