Abstract:
1. A method of making a three-dimensional object from a photohardenable resin, comprising: providing original solidification energy source event data corresponding to a cross-section of the three-dimensional object, wherein the original solidification energy source event data comprises a plurality of original solidification energy source event data items, and each original solidification energy source event data item is associated with a position along a build envelope scanning axis and is indicative of a change in the energization state of a selectively, activatable and deactivatable laser diode; calculating modified solidification energy source event data corresponding to the cross-section of the three-dimensional object, wherein the modified solidification energy source event data comprises a plurality of modified solidification energy source event data items, each modified solidification energy source event data item corresponds to one of the respective original solidification energy source event data items and is based on the associated position along the build envelope scanning axis of its corresponding original solidification energy source event data item; solidifying the solidifiable material in accordance with the modified solidification energy source event data to form the cross-section of the three-dimensional object, comprising:
