An Additive Manufacturing quality management system, comprising: an AM machine configured to fabricate AM components in accordance with AM design data; a temperature sensor configured to record fusion temperatures during fabrication of the AM components; a processor coupled to the temperature sensor; and a computer-readable storage medium storing a computer-executable code that, when executed by the processor, causes the AM quality management system to: compile part-specific sensor profiles (110, 112, 114) from sensor readings captured by the temperature sensor as the AM machine fabricates the AM components, each part-specific sensor profile (110, 112, 114) containing sensor readings gathered as time-phased temperature measurements that include a characteristic plotting local temperature-versus-time over a timeframe encompassing a fusion event and a duration of time at which a weld pool remains above a predetermined minimum fusion temperature for a layer; and generate notifications indicating whether any of the AM components produced by the AM machine are desirably subject to remedial action based, at least in part, on a comparison of the duration of time the weld pool remains above the predetermined minimum fusion temperature for the part-specific sensor profiles (110, 112, 114) to a baseline sensor profile corresponding to the AM design data. an AM machine configured to fabricate AM components in accordance with AM design data; a temperature sensor configured to record fusion temperatures during fabrication of the AM components; a processor coupled to the temperature sensor; and a computer-readable storage medium storing a computer-executable code that, when executed by the processor, causes the AM quality management system to: compile part-specific sensor profiles (110, 112, 114) from sensor readings captured by the temperature sensor as the AM machine fabricates the AM components, each part-specific sensor profile (110, 112, 114) containing sensor readings gathered as time-phased temperature measurements that include a characteristic plotting local temperature-versus-time over a timeframe encompassing a fusion event and a duration of time at which a weld pool remains above a predetermined minimum fusion temperature for a layer; and generate notifications indicating whether any of the AM components produced by the AM machine are desirably subject to remedial action based, at least in part, on a comparison of the duration of time the weld pool remains above the predetermined minimum fusion temperature for the part-specific sensor profiles (110, 112, 114) to a baseline sensor profile corresponding to the AM design data. compile part-specific sensor profiles (110, 112, 114) from sensor readings captured by the temperature sensor as the AM machine fabricates the AM components, each part-specific sensor profile (110, 112, 114) containing sensor readings gathered as time-phased temperature measurements that include a characteristic plotting local temperature-versus-time over a timeframe encompassing a fusion event and a duration of time at which a weld pool remains above a predetermined minimum fusion temperature for a layer; and generate notifications indicating whether any of the AM components produced by the AM machine are desirably subject to remedial action based, at least in part, on a comparison of the duration of time the weld pool remains above the predetermined minimum fusion temperature for the part-specific sensor profiles (110, 112, 114) to a baseline sensor profile corresponding to the AM design data.
