Claim 14:
15. A method comprising:
accessing a part model comprising a three-dimensional representation of a part;
accessing a material profile of a material selected for the part, the material profile relating exposure energy and three-dimensional polymerization geometry of the material;
segmenting the part model into a set of model layers;
segmenting a first model layer, in the set of model layers, into a first set of model volumes;
segmenting a second model layer, in the set of model layers and above the first model layer, into a second set of model volumes;
detecting a first superficial model volume, in the second set of model volumes of the second model layer, intersecting a first upward-facing surface of the part model;
selecting a first interior model volume, in the first set of model volumes of the first model layer:
below the second superficial model volume; and
fully contained within the part model;

based on the material profile, calculating a first exposure energy predicted to yield a first three-dimensional polymerization geometry approximating a first contour of the first upward-facing surface contained within the first superficial model volume when projected onto the material during a build;
populating a first print image with the first exposure energy in a first image area corresponding to the first interior model volume in the first model layer; and
storing the first print image in a print file for the part.
