1. A method comprising:
determining, using a processor, a representation of a model of a part as a plurality of discrete three-dimensional (3D) volume elements, the part including a first region and a second region, the second region surrounding a perimeter of the first region;
determining, using the processor, a first material property value to assign to a first one of the plurality of 3D volume elements in the first region and a second material property value to assign to a second one of the plurality of 3D volume elements in the second region, the second material property value different from the first material property value, wherein the first and second material property values are classified into a predetermined number of bins that correspond to a plurality of different additive manufacturing (AM) print parameter sets wherein at least one of dilation or smoothing is used to expand at least one of (a) the first one of the plurality of 3D volume elements in the first region or (b) the second one of the plurality of 3D volume elements in the second region;
generating, using the processor, a plurality of transfer functions to determine relationships between the first and second material property values and a plurality of desired AM print parameter sets;
automatically determining, using the processor and based on the plurality of transfer functions, an assignment of a first one of the plurality of different AM print parameter sets to the first one of the plurality of 3D volume elements and an assignment of a second one of the plurality of different AM print parameter sets to the second one of the plurality of 3D volume elements;
validating, using the processor, the determined assignments of the plurality of different AM print parameter sets for the plurality of 3D volume elements based on the plurality of transfer functions; and
transmitting, using the processor, a record of the determined assignments of the plurality of different AM print parameter sets to an AM controller, the AM controller to control an AM system to generate the part based on the model and the determined assignments of the plurality of different AM print parameters sets to each of the plurality of 3D volume elements.
