Abstract
A printer is configured to detect a missing material drop in a top layer of a part being printed in the printer. Upon detection of a missing material drop, the printer moves the platform on which the part is being formed in a direction opposite to the process direction to position the area in which the drop is missing beneath an ejector that is operated to eject a drop in the area. This procedure is performed for each area in which a missing drop was detected before the next layer of the part is formed.
