Abstract

See full text

A three-dimensional object printer generates image data of an object being formed in the printer with an optical sensor array and identifies the color of an upper surface of the object. The controller compares the identified color to a predetermined range about an expected color for the upper surface and operates ejectors to eject material of a color different than the identified color in response to the identified color being outside of the predetermined range.
