Abstract
A method of generating a tool path for an additive manufacturing process, the tool path having an input polygon for a thick region, and an input path for a wire region. The method includes offsetting the input polygon by a minimum step over distance, creating a set of contour parallel offset lines, computing path segments from a medial axis transform of the input polygon, computing a dilation of the medial axis path by a radius approximately half the step over distance, producing a dilated medial axis, clipping the contour parallel offset paths by the medial axis path, producing, and recursively connect the medial axis paths with the clipped contour parallel paths.
