1. A method of forming a three-dimensional object from an object representation having a build axis dimension, the method comprising:

  • providing a set of object data corresponding to a plurality of locations in the object, each location corresponding to a position along a build axis dimension and a position relative to the build axis dimension;

    subdividing the set of object data into a first exposure data subset and a second exposure data subset, wherein the first exposure data subset defines a first subset of positions relative to the build axis, and the second exposure data subset defines a second subset of positions relative to the build axis;

    providing a first exposure surface of a solidifiable material; and

    solidifying only the first subset of positions on a first exposed surface of solidification material without solidifying the second subset of positions.
