Assignee: SIGMA ADDITIVE SOLUTIONS, INC.
Field: Materials, metallurgy (Chemistry)
Classification: CPC B  Y | IPC B

Claim 0:
1. An additive manufacturing system, comprising:
a scan head;
a build plane;
a heat source configured to transmit energy through the scan head and toward the build plane to generate a melt pool;
an optical sensor configured to receive light through the scan head, wherein the light is emitted by the melt pool; and
a processor configured to execute computer code that that causes the additive manufacturing system to carry out an additive manufacturing operation to produce a part, the additive manufacturing operation comprising:
depositing a layer of metal powder on the build plane;
generating the melt pool by melting a portion of the layer of metal powder using the heat source;
generating a dataset from an output of the optical sensor;
comparing the dataset with a known-good range of a baseline dataset to determine whether one or more portions of the part may include a manufacturing defect; and
in response to the comparing, changing a parameter of the heat source.
