Abstract
Despite tremendous potential cost advantages, there is one very serious obstacle in the path of successful, widespread adoption of Direct Digital Manufacturing as a viable aerospace manufacturing technique: namely qualification and certification of processes, materials, and components. This roadblock to adoption is significant and dramatic. The cost implications alone of introducing a new material to aerospace, either on the airframe side or the engine side, are considerable, and the general rule of thumb is 2 years and $2M - $5M in non-recurring testing costs. Our unique approach to rapid qualification and certification combines limited and initial mechanical testing, advanced in-process sensing and process monitoring, microstructural characterization, and a statistical classification methodology that is truly multi-variate and can fuse these various inputs to result in a decision on whether or not a specific weld, deposit, or even part belongs in the same population as the nominal baseline certified parts, or is it anomalous in some way.
