Scope Additive Manufacturing (AM) involves unique processing cycles, producing microstructure and material properties that differ from those produced by conventional methods.

AM continues to attract attention of professional communities including research, design, and process engineers. However, more research is still needed to fully understand the capabilities of these processes and the correlation between process conditions, process parameters, microstructure and other material properties.

Titanium-based alloys are attractive for industrial use thanks to excellent properties in terms of specific strength, biocompatibility, and corrosion resistance. Titanium alloys are also expensive and challenging to machine. Thus it is not surprising that titanium attracts a strong interest within the AM community. The purpose of this symposium is to discuss AM processes and AM materials having titanium as the main constituent, with focus on the correlation between processing conditions and microstructure/material performance, in a broad perspective. We welcome contributions on all types of titanium-based materials: Unalloyed, alloys, intermetallics, composites, etc. We also welcome contributions on new innovative titanium alloy compositions tailored for additive manufacturing.
