THREE-DIMENSIONAL (3D) OBJECT PRINTING SYSTEM THAT COMPENSATES FOR MISREGISTRATION
A three-dimensional object printer comprises a platen (120), a gantry (130) positioned above the platen, an ejector head (140) positioned on the gantry, a sensor (146), and a controller. The controller is configured to operate the ejector (142) to eject at least one drop of material toward the plate...

Zusammenfassung: | A three-dimensional object printer comprises a platen (120), a gantry (130) positioned above the platen, an ejector head (140) positioned on the gantry, a sensor (146), and a controller. The controller is configured to operate the ejector (142) to eject at least one drop of material toward the platen at an upper build level (112) 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. |
