ELECTROPHOTOGRAPHY-BASED ADDITIVE PRINTING WITH IMPROVED LAYER REGISTRATION

Abstract:

An additive manufacturing system includes a transfer belt traveling along a belt path. An electrophotography engine positioned along belt path deposits a part material layer onto the transfer belt, and an image transfer assembly positioned along the belt path transfers the part material layer onto a build platform. An image sensing system positioned along the belt path between the electrophotography engine and the image transfer assembly captures an image which is analyzed to determine an in-track registration error. An in-track position of the build platform is adjusted to compensate for the in-track registration error.
