Claim 18:
19. 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;
detecting a first upward-facing surface in the part model;
defining a first model volume:
in a first model layer in the set of model layers;
adjacent the first upward-facing surface; 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 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 model volume in the first model layer; and
storing the first print image in a print file for the part.
