The particular claims are 1 and 23:
1. An improved method of stereolithographically forming a three-dimensional object by forming cross-sectional layers of said object from a material capable of physical transformation upon exposure to synergistic stimulation comprising the steps of receiving data descriptive of said cross-sectional layers, forming said cross-sectional layers by selectively exposing said material to said synergistic stimulation according to said data descriptive of said cross-sectional layers to build up the three-dimensional object layer-by-layer, the improvement comprising the steps of:
- modifying data descriptive of at least a portion of at least one cross-sectional layer by copying said data from a first cross-section to a second cross-section; and
- using said modified data in forming said three-dimensional object.
23. An improved method of stereolithographically forming a three-dimensional object by forming cross-sectional layers of said object from a material capable of physical transformation upon exposure to synergistic stimulation comprising the steps of receiving data descriptive of said cross-sectional layers and forming said cross-sectional layers by selectively exposing said material to said synergistic stimulation according to said data descriptive of said cross-sectional layers to build up the three-dimensional object layer-by-layer, the improvement comprising the step of:
- modifying data descriptive of at least a portion of at least one cross-sectional layer by shifting said data from a first cross-section to a second cross-section; and
- using said modified data in forming said three-dimensional object.
Am I missing something, or are these claims exactly the same, aside from the extra "and" in one of the claims, which doesn't appear to change the meaning...
If so, it may be possible for them to work around this by, for example, instead of going from top to bottom, left to right? Or, maybe forming it in a spiral or unconventional shape?
