Claim 0:
1. An additive manufacturing system comprising:
a first electronic nose and a second electronic nose, the first electronic nose being mounted to a first side of an extruder head and the second electronic nose being mounted to a second side of the extruder head, each said electronic nose comprising:
a housing having openings on corresponding ends thereof to enable air flow, the housing having an air channel for air to flow between the ends;
a plurality of thin film gas sensors, each having an active sensor portion in the air channel; and
a mount configured to mount the housing to the extruder head of an additive manufacturing device, and

a processor configured to:
supply power to the plurality of thin film gas sensors to bias the sensors;
receive output from each of the plurality of thin film gas sensors;
determine whether there is an abnormality in an additive manufacturing process manufacturing a product from one or more materials or composite materials based on one or more combinations of the output from each of the plurality of thin film gas sensors during the additive manufacturing process and from a deployed machine learning model; and
generate a report for the additive manufacturing process containing the abnormality determination.
