Abstract
Solid imaging apparatus and methods for use are disclosed that reduce the amount of uncured solid imaging build material remaining on a completed build object following the completion of the solid imaging build process. The amount of uncured build material is reduced through the use of either an uncoating web that removes excess build material from the build object during the course of the building process or an ink jet source of build material that uses only as much build material as is necessary for the fabrication of the build part. Also disclosed is an imager assembly for use with such a solid imaging apparatus that incorporates two or more individual imagers in an array and accounts for variations in the intensity and alignment of adjacent imagers. The apparatus can be modified for semi-continuous operation and for integrating into a manufacturing operation, if desired.
