1. A method for additively manufacturing a structure, comprising:
slicing a virtual model of the structure into a plurality of layers;
applying at least one infill pattern to each of the plurality of layers;
distributing a plurality of points along lines of the at least one infill pattern;
sequentially grouping the plurality of points into at least one path;
validating the at least one path for fabrication by an additive manufacturing machine; and
causing the additive manufacturing machine to discharge material along the validated at least one path, wherein validating includes:
generating a vector normal to the at least one path at each of the plurality of points;
examining a rate of change between at least two of the vectors normal to the at least one path;
comparing the rate of change with a threshold rate of change; and
selectively filtering the plurality of points based on the comparison.
