An ongoing concern with critical and ongoing relevance to multidisciplinary Modeling & Simulation (M&S), and across many I/ITSEC domains of interest -- is the emergent and evolutionary process relationship between Design and Manufacturing.  Lighter, stronger, and more complex materials, shapes, subsystems, and design components can be achieved by leveraging advanced, integrated, and cooperative design & additive manufacturing technologies in a manner that is more process and cost-efficient than traditional standalone product design, and numerous conventional (and antiquated) “subtractive” methods of manufacture.  As these technologies continue to mature, the iterative pipeline between preliminary brainstorming, to Concept Modeling, to 2D computer-aided design, to 3D digital (solid model) Design, to Rapid Prototyping, to final product Manufacturing is continually converging into a holistic process continuum that will ultimately improve design process efficiency and effectiveness, final product integrity, and overall rates of success. 

However, as with all disruptive and bleeding-edge technologies, related cybersecurity concerns have already begun to manifest within the advanced technological domains of 3D Printing (3DP) and Design for Additive Manufacturing (DFAM).  Open source features and subsequent “democratization” of DFAM technologies that permit the production of items that were once limited to factories imparts an inherent flexibility that has opened the door for cybercrimes, terrorist acts, and other untoward activities.  Accordingly, in this timely and innovative emerging topics Tutorial, we explore and investigate how “Innovating and Accelerating Training: Adapting to an Unexpected Future!” -- with respect to the critical and ever-emerging interrelationship between 3DP/DFAM -- and Cybersecurity can immensely benefit an M&S practitioner be better prepared for the future.  After a brief exploration of foundational material (e.g., Design/Manufacturing fundamentals), we explore recent and timely examples of cybersecurity concerns related to 3DP and DFAM.  In spite of these recent and ongoing cautionary tales, we then highlight significant examples and Case Studies, each drawn from current literature, to demonstrate how recent industry has made optimal use of the DFAM pipeline -- and across different domains of interest (e.g., aerospace, biomedical, and manufacturing). These topics and subject areas will be presented directly and explicitly with relation to the essential context of advanced M&S, as well as the overarching I/ITSEC mission - and its key foundational pillars - Training, Simulation, and Education.
