Abstract:
1. A method of producing a part using a three-dimensional modeler, wherein the modeler produces the part by selectively curing layers of solidifiable liquid material with actinic radiation projected from an imager, the method comprising: determining an intensity profile of the actinic radiation projected from the imager; then automatically positioning a center of the part to be produced proximate a portion of the determined intensity profile defining the highest intensity of the actinic radiation; providing a single layer of the solidifiable liquid material proximate the image plane of the modeler; projecting the actinic radiation to selectively cure the single layer of the solidifiable liquid material; providing a single layer of the solidifiable liquid material proximate the image plane of the modeler; and repeating the projecting of actinic radiation and the providing of a single layer of the solidifiable liquid material to produce the part.
