Abstract
Functionally graded materials can be prepared through additive manufacturing by determining the path that a head of 3D printer can follow while extruding a material mix of a required composition at required points of a layer of an FGM. Each point within the layer is evaluated regarding the directions within which the printing head can move into from that point while extruding the material mix of a required composition. Based on the evaluation, a multitude of polygons are defined within the polygonal shape that are guaranteed to be printable. A path can be designed for the printing head to follow to print all of the defined polygons, and consequently, to print the entire polygonal layer. Material extrusion commands are generated for the printing head.
