While the task ahead is conceptully clear, and much progress is under way, a number of gaps need to be addressed, including:
- Incomplete understanding of raw material properties
- Insufficient knowledge of effect of process variables across scales
- Lack of methods for characterizing structure of products and in-process materials
- Underdeveloped process monitoring tools
- Lack of control methodologies for powder-based processes
- Over-reliance on batch manufacturing methods
In this talk, these gaps are discussed, recent progress in addressing themis presented, and a way forward is outlined.
