In this study, we propose a tool-path generation approach for material extrusion-based
additive manufacturing (AM) that considers the machining efficiency and fabrication
precision, which are inherent drawbacks of general AM techniques compared with
conventional manufacturing methods. The proposed approach aims to tackle the generation
of direction-parallel tool-paths for the interior filling of simple connected areas, which
comprises three main steps:(1) determining the inclination of reference lines;(2) generating …
