Assignee: LAWRENCE LIVERMORE NATIONAL SECURITY, LLC
Field: Computer technology (Electrical engineering)
Classification: CPC B  G | IPC B  G

Claim 8:
9. One or more computing systems for identifying a control move for controlling a material extrusion device to extrude a filament of an ink to manufacture a product, the one or more computing systems comprising:
one or more computer-readable storage mediums storing computer-executable instructions for controlling the one or more computing systems to:
collect one or more measurements from one or more sensors that monitor material extrusion processing of the material extrusion device, each measurement representing an internal state of the material extrusion processing during extrusion of the filament;
collect an image of a portion of the filament while the filament is being extruded and while the portion of the filament is in motion and not in contact with any surface;
apply a classifier to the collected image of the filament as the filament is extruded, to generate an image-derived state characterizing the filament;
estimate a derived state of the material extrusion processing based on the internal state and the image-derived state; and
determine a control move based on the internal state, the image-derived state, and the derived state; and

one or more processors for executing the computer-executable instructions stored in the one or more computer-readable storage mediums.
