Abstract

A manufacturing computer device for dynamically adapting additive manufacturing of a part is configured to store a model of the part including a plurality of build parameters. The manufacturing computer device is also configured to receive current sensor information of at least one current sensor reading of a melt pool from a build of the part in progress. The computer device is further configured to determine one or more attributes of the melt pool based on the current sensor information. Moreover, the computer device is configured to calculate at least one unseen attribute of the melt pool. In addition, the computer device is configured to determine an adjusted build parameter based on the at least one unseen attribute, the one or more attributes, and the plurality of build parameters. The computer device is also configured to transmit the adjusted build parameter to a machine currently manufacturing the part.
