THREE-DIMENSIONAL (3D) OBJECT PRINTING SYSTEM THAT COMPENSATES FOR MISREGISTRATION

The invention discloses a three-dimensional object printer. The three-dimensional object printer comprises a platen, a gantry positioned above the platen, an ejector head positioned on the gantry, a sensor, and a controller. The controller is configured to operate the ejector to eject at least one drop of material toward the platen at an upper build level and determine process and cross-process differentials between a fiducial and the at least one drop of material deposited on the upper build surface. The controller is also configured to determine an ejector head shift in a process direction and a cross-process direction associated with each of the plurality of build levels based at least in part on the determined process and cross-process differentials and a number of build levels between the base build level and the upper build level. 本发明公开了一种三维物体打印机，该三维物体打印机包括台板、定位在该台板上方的台架、定位在该台架上的喷射器头、传感器和控制器。该控制器被配置为操作该喷射器以使至少一个材料液滴朝向该台板喷射在上部构建层级处，并且确定框标与沉积在该上部构建表面上的该至少一个材料液滴之间的过程差分和交叉过程差分。该控制器还被配置为至少部分地基于该所确定的过程差分和交叉过程
