Additive Manufacturing Unique Serialization
Current methods of identifying a unique part involve adding a unique serial number to the part. There are many reasons that manufactured parts receive a serial number. They enable traceability of a part throughout its lifecycle, and ensure the part is not a counterfeit; however, labels and stamped codes...
