What is it about?
Additive manufacturing (also known as 3D printing) promises to change the manufacturing landscape. It has advantages associated with time to product realization, component repair, shortening supply chains, and costs. However, the properties must also be comparable (or exceed) those of conventional processing. Microstructure governs properties. This paper is a fundamental review of the physical details associated with additive manufacturing, and how it influences microstructure (and by extension, properties).

Why is it important?
This article is a critical review of the literature - not only recent literature related to additive manufacturing, but also relevant fundamental literature on solidification, elemental species flux at liquid gas interfaces, and phase transformations. The article provides a framework to understand the evolution of composition and microstructure in additively manufactured metallic materials.
