TL;DR: A review of the emerging research on additive manufacturing of metallic materials is provided in this article, which provides a comprehensive overview of the physical processes and the underlying science of metallurgical structure and properties of the deposited parts.

TL;DR: The printability, or the ability of an alloy to avoid these defects, can be examined by developing and testing appropriate theories, and a theoretical scaling analysis is used to test vulnerability of various alloys to thermal distortion.

TL;DR: In this article, a digital twin of the laser-based directed energy deposition additive manufacturing (DED) process is proposed to provide accurate predictions of the spatial and temporal variations of metallurgical parameters that affect the structure and properties of components.

TL;DR: In this article, the authors focus on the available mechanistic models of additive manufacturing (AM) that have been adequately validated and evaluate the functionality of AM models in understanding of the printability of commonly used AM alloys and the fabrication of functionally graded alloys.

TL;DR: The role of cooling rate, microstructure, alloy composition and post process heat treatment on the hardness of additively manufactured aluminum, nickel, titanium and iron base components is examined to understand the relative roles of manufacturing processes.
