||There is now little need to motivate the research topic of additive manufacturing (AM) in materials science and engineering. At materials conferences there are now a suite of AM-related symposia to attend, ranging from physically metallurgy to fatigue and fracture. Advancements in those (and many other) fields has been aimed at understanding fundamental processes of AM in an attempt to further advance the technology for at-scale industrial application. This symposium focuses on those latter issues: bridging the gap between fundamental science and the requisite process qualification and component certification that must occur before AM parts may be deployed in service. Process qualification involves the establishment of material and process specifications in support of process control and acquisition of data to determine statistically-substantiated mechanical properties and design values. Component certification involves the down-selection of qualified processes and subsequent demonstration of component performance in expected, service-like conditions. This symposium will organize researchers in the context of bridging the scalability gap to industrialization through open discussion and presentation of recent attempts at AM qualification and certification, successes, failures, and future expectations. Specifically, the organizers will focus on recruiting presentations in four main areas of interest in support AM process qualification and component certification: process control; test-driven methods; physics-based simulation methods; and data-driven methods.
