Patent ID: 8326024

Claim:
A method of forming a three-dimensional object from an object representation having a build axis dimension, the method comprising: providing a solidification substrate; supplying a first volume of the solidification material adjacent the solidification substrate to create a first exposed surface of the solidifiable material; 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; solidifying only the first subset of positions on the first exposed surface of solidification material without solidifying the second subset of positions; providing a second exposed surface of the solidifiable material; solidifying the second subset of positions on the second exposed surface of solidifiable material to a first depth without solidifying the first subset of positions on the second exposed surface of solidifiable material; providing a third exposure surface of the solidifiable material; solidifying the first subset of positions on the third exposure surface without solidifying the second subset of positions on the third exposure surface; and solidifying the first subset of positions to a second depth without solidifying the second subset of positions.
