Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a system and method for correcting object defects in three-dimensional object printing.SOLUTION: 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 an 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 where a missing drop was detected before the next layer of the part is formed.SELECTED DRAWING: None 【課題】３次元物体印刷での物体の不具合を修正するシステムおよび方法の提供。【解決手段】プリンタは、プリンタで印刷された部分の最上層の欠落した材料の滴を検出するように構成されている。欠落した材料の滴を検出した状態で、プリンタは、領域で滴を噴出するために作動される噴出部の真下で滴が欠落している領域を配置するために、部分がプロセス方向と反対方向に形成されるプラットフォームを移動させる。この手順は、部分の次の層が形成される前に、欠落した滴が検出されたそれぞれの領域に対して実行される。【選択図】なし
