Additive Manufacturing (AM, aka 3DPrinting) is a potentially revolutionary manufacturing technology that is changing how both polymer and metal parts can be designed and fabricated. Geometrical complexity, gradient materials, and one-piece assemblies, all of which are difficult or impossible to fabricate with traditional removal processes, are all realizable with additive manufacturing. However, there are several technical challenges that are preventing more widespread adoption of additive manufacturing systems, especially for high-value, mission-critical parts. Chief among these challenges are a lack of full understanding of AM processes, especially for metal AM processes, and the factors influencing the mechanical properties of AM parts. In this talk I will give a brief overview of additive manufacturing processes, describe the technical challenges that are hindering broad adoption of AM parts for critical applications, and describe some recent efforts to measure and better understand both AM processes and AM material properties.
