Patent attributes
An article of manufacture is disclosed that includes an infill generated utilizing three dimensional (3D) printing. Infill is generated utilizing segments of filament, such as, but not limited to continuous carbon fiber-reinforced thermoplastic filament. Other materials may also be suitably employed. Approaches to tool path generation which accomplish the 3D printing desired are addressed in which material runs of filament are applied that distribute where cuts, beginning, or ends of segments occur or points where ends of segments are anchored to the article to form the desired infill. Aspects of one approach include first generating a meta tool path for the infill and then adapting that tool path to an actual infill tool path by pruning any segments in the meta tool path extending outside the perimeter of the article and identifying anchor points to the article from observed intersections of the meta tool path and said perimeter.
