Title:

SYSTEMS AND METHODS FOR ADDITIVE MANUFACTURING CALIBRATION

Document Type and Number:

WIPO Patent Application WO/2019/139775

Kind Code:

A1

Abstract:

An additive manufacturing system including a consolidation device, a build platform, an optical detector, and a controller is provided. The consolidation device is configured to form a build layer of a component. The build platform is configured to rotate about a build platform rotation axis extending along a first direction. The optical detector is configured to detect locations of at least two alignment marks. The controller is configured to receive locations of the at least two alignment marks from the optical detector. The controller is also configured to determine the locations of the build platform rotation axis and a build platform rotation center point based on a comparison between the at least two alignment marks, wherein the build platform rotation center point lies along the build platform rotation axis. The controller is further configured to control the consolidation device to consolidate a plurality of particles on the build platform.
