Scope Additive Manufacturing (AM) or“3D printing” is a rapidly expanding, multi-disciplinary field that uses various processes and materials to produce structures through layer-by-layer additive techniques, enabling new component designs and tailored structures. AM is moving beyond rapid prototypingparts and into direct fabrication of end-use products like gas turbine engine components and medical implants.The goal of this symposium is to promote informational exchange among academia, government labs, and industry on the materials aspects of AM: processing techniques, materials characterization, certification, modeling and simulation encompassing all AM materials (metals and alloys, polymers, ceramics, and biomaterials). Specific topics of interest include:

Processing: A given processing technique used to assemble the part defines the form and type of material employed. The processing parameters and any post-processing can influence the material properties and product usefulness. New processing techniques •thermal transport and solidification • residual stress and distortion • phase transformations •microstructure •in situ process monitoring and controls •process optimization.
Materials Characterization: The ability to characterize the material before, during, and after manufacture can provide understanding of processing effects on material behavior and knowledge for material selection criteria. Materials characterization techniques •test methods for properties of raw materials • test methods for AM-produced products.
Certification: Proper specifications for raw materials, processing parameters, and end-product performance can be employed to ensure successful finished parts. Qualification and certification of AM starting materials and end products.
Numerical Modeling and Simulation: Gathering the fundamental materials properties and processing effects to predict end product performance (process – structure – property) can provide guidance for new and existing processes. Numerical modeling • application of Integrated Computational Materials Engineering (ICME).
