1. A system for generating, receiving, and processing of multi-mode elastic waves and field sensor data in at least one test artifact to assess the quality of an article being built, and its source materials, additive manufacturing machines and processes during a fabrication cycle, comprising:
a computing device comprising one or more:
a memory unit;
a storage medium;
a library of historical data sets comprising of elastic wave and field sensor data, a set of additive manufacturing machine and process parameters, and post-production quality assessments of the previously built articles and their corresponding test artifacts;
a computer processor in connection with the memory unit and the storage medium that are readable and writable by the processor;
a set of software instructions for synchronizing and executing computing and data exchange tasks and governing data flow in the computing device and external devices and sensors;
at least one data port and interface for external devices and sensors;
at least one data port for external communications and networking;
a central analysis software tool for predictive analysis and the generation of warnings and messages; and
a graphical user interface software tool that provides an operator with remote real-time access to the computing device for the controls of the system;
at least one test artifact;
at least one multi-mode elastic wave generating transducer;
at least one multi-mode elastic wave receiving transducer;
at least one wave delay line causing time delays in traveling elastic waves;
at least one scanning field sensor;
at least one near-field sensor;
at least one tracker that moves a field sensor along a predefined path on a test artifact;
a multi-channel pulser/receiver unit generating and receiving transient electrical signals;
an analog-to-digital signal converter unit;
a communication utility for networking and coordinating one or more systems, additive manufacturing machines, and computing devices; and
at least one physical or data port for mounting and interfacing the system to an additive manufacturing machine.
