Abstract Scope Metal based additive manufacturing (AM) has proven to be a majorly disruptive materials processing route that is central to the so-called Industrial Revolution 4.0. To date a collection of processes have been established under the concepts of metal based AM, all nuanced in the way in which material is incrementally added to a part. This overview of the recent progress in metal based AM provides an overview of the different techniques, their market readiness, the fundamental science driving the processes, and applications of interest. The differences between the processing routes of powder bed fusion, directed energy deposition, and wire arc additive manufacture is emphasized with regard to process capabilities, feedstock material forms, and maturity. Established and promising applications of these techniques are discussed including AM for the creation of complex tools and dies with conformal cooling for improved thermal management of casting processes.
