A metallurgist shares insights on choosing the ideal metals for 3D metal manufacturing and ensuring quality production.
In this article, a brief introduction to commonly used metal and alloy powders for additive manufacturing (AM) is given. In addition, the reader will gain a basic understanding of metal structure, metallurgy, properties, and state-of-the-art in-process quality control measures used to reliably influence the performance of a part in service. For a more rigorous study of the AM process, structure, and properties of metallic components, the reader is referred to a recent review article1 and the comprehensive overview book on the fundamental elements and processes used to 3D print metal.
