Abstract
A three-dimensional object printer generates image data of an object being formed in the printer with a plurality of light sources and a plurality of optical sensor arrays. A controller receives the image data and identifies measurements of the object and of the features of the object. The controller compares the measurements to expected measurements and adds material or removes material from the object in response to the identified measurements being outside a predetermined range about the expected measurements.
