Metal additive manufacturing has been researched over the past couple of decades for the fabrication and characterization of novel alloy systems. However, for its advancement, it is necessary for metal AM techniques to produce parts with standard compositions that can go head-to-head against their conventional counterparts in the most widespread applications. The tooling industry is one that can reciprocate the benefits obtained from metal AM by providing means of quick testing and standardisation of as-built parts. This talk presents the microstructural investigations and mechanical response obtained in H13 tool steel parts printed by the DED process. It also provides a framework for process parameter optimization in DED processes where the complex interplay of process parameters governs the printability of a part. The DED’ed tool steel parts printed with the optimized process parameters showcase > 99.95%-part density in the as-built condition – free from geometrical constraints and possessing superior mechanical properties.
