Workshop Statement of Task

A National Academies of Sciences, Engineering, and Medicine-appointed ad hoc committee will plan and organize a 3-day workshop to explore the frontiers of integrated data-driven modeling for additive manufacturing. This workshop will convene leading experts in online monitoring, science of materials and mechanics, optimization and controls, and qualification and certification from the United States and the European Union to discuss approaches to and challenges with the following:

  • Measuring and modeling process monitoring and control;
  • Developing models to represent microstructure evolution, alloy design, and part suitability;
  • Modeling phases of process and machine design; and
  • Accelerating product and process qualification and certification.

Additive manufacturing (AM) is the process in which a three-dimensional object is built by adding subsequent layers of materials. AM enables novel material compositions and shapes, often without the need for specialized tooling. This technology has the potential to revolutionize how mechanical parts are created, tested, and certified. However, successful real-time AM design requires the integration of complex systems and often necessitates expertise across domains. Simulation-based design approaches, such as those applied in engineering product design and material design, have the potential to improve AM predictive modeling capabilities, particularly when combined with existing knowledge of the underlying mechanics. These predictive models have the potential to reduce the cost of and time for concept-to-final-product development and can be used to supplement experimental tests.

The National Academies convened a workshop on October 24-26, 2018 to discuss the frontiers of mechanistic data-driven modeling for AM of metals. Topics of discussion included measuring and modeling process monitoring and control, developing models to represent microstructure evolution, alloy design, and part suitability, modeling phases of process and machine design, and accelerating product and process qualification and certification. These topics then led to the assessment of short-, immediate-, and long-term challenges in AM. This publication summarizes the presentations and discussions from the workshop.
