摘要
The present invention discloses a method of planning a 3D printing path based on Fermat's spiral. The method comprises generating a plurality of iso-contours for a given topological connected region, wherein adjacent iso-contours of the plurality of iso-contours have a set spacing therebetween. The method also comprises constructing a spiral connected graph according to the plurality of iso-contours and generating a spiral connected tree according to the spiral connected graph. The method further comprises connecting a subset of the plurality of iso-contours according to the spiral connected tree to form a connected Fermat spiral. The method additionally comprises smoothing the connected Fermat spiral through a global optimization method based on a width of the printing path being consistent.
