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: In this article, a well-tested, three-dimensional, transient heat transfer and fluid flow model is used to accurately calculate transient temperature field for the residual stress and distortion modeling.

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: 3D printing is now widely used in aerospace, healthcare, energy, automotive and other industries, and is the fastest growing sector, yet its development presents scientific, technological and economic challenges that must be understood and addressed.

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.
