Claim 12:
13. The method of claim 1:
wherein selecting the first interior model volume comprises:
based on the first superficial model volume intersecting the first upward-facing surface defining a concave profile characterized by an effective tangent inclined from a horizontal plane, parallel to the first model layer, by greater than a threshold angle:
selecting the first interior model volume, in the first model layer, adjacent the first superficial model volume; and
selecting a second interior model volume, in the first model layer, adjacent the first superficial model volume;

wherein calculating the first exposure energy comprises:
based on the material profile, calculating the first exposure energy predicted to yield the first three-dimensional polymerization geometry intersecting the first upward-facing surface contained within the first superficial model volume when projected onto the material during the build;

further comprising:
based on the material profile, calculating a second exposure energy predicted to yield a second three-dimensional polymerization geometry intersecting the first upward-facing surface contained within the first superficial model volume when projected onto the material during the build, the first three-dimensional polymerization geometry and the second three-dimensional polymerization geometry cooperating to approximate the first contour of the first upward-facing surface contained within the first superficial model volume; and
populating the first print image with the second exposure energy in a second image area corresponding to the second interior model volume in the first model layer.
