Metal additive manufacturing (MAM) is maturing as a production route and is gaining a strong foothold within industry. MAM covers several different methods including laser powder bed fusion (LPBF) and binder jetting. A common feature of the MAM methods, such as LPBF, is the unorthodox microstructure resulting from the very rapid solidification, inherent to the process. This provides new opportunities as well as challenges with respect to heat treatment and surface engineering. Heat and surface treatment methods developed for conventionally manufactured materials with perhaps the same composition but a very different microstructure, are generally inapt or can even be detrimental for MAM parts. On the other side, the unorthodox microstructures can provide an opportunity to achieve properties that are not obtainable through heat/surface treatment of conventionally manufactured metals.

The present contribution provides an overview of how to exploit the unorthodox microstructure resulting from printing. How can we design new heat treatments and surface engineering processes for exploiting and optimizing the unique “features” associated with MAM? Focus is on research from the authors’ own laboratory and will address different metals, including titanium alloys and steels.
