| Abstract Scope |
Due to their unique combination of properties, titanium alloys can be regarded as a “one size fits all” solution for many metal additive manufacturing (AM) applications. Such a solution could significantly simplify or eliminate material selection and/or feedstock inventorying. However, titanium alloys are also particularly susceptible to thermal processing, meaning the complex thermal histories of beam-based AM (e.g. powder bed fusion and directed energy deposition) can produce unacceptable and/or unpredictable results. Non-beam metal AM technologies (e.g. material extrusion AM and binder jetting) hold significant promise, as they enable more predictable microstructural and mechanical property engineering. However, these technologies have their own hurdles, as they often require binders that may contaminate titanium alloys and/or require significant densification during subsequent sintering processes. This talk will discuss the various benefits and hurdles of non-beam AM of titanium alloys through the lens of both theory and published literature, as well as original experimental results. |
