1. A method of planning a 3D printing path for controlling a 3D printer to print an object, the method comprising:

  • 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;

    constructing a spiral connected graph according to the plurality of iso-contours;

    generating a spiral connected tree according to the spiral connected graph;

    generating the 3D printing path based on connecting a subset of the plurality of iso-contours according to the spiral connected tree to form a connected Fermat spiral; and

    smoothing the 3D printing path through a global optimization method based on a width of the printing path being consistent; and

    controlling a path of a print head of the 3D printer according to the 3D printing path to print the object.
