TLDR
The state-of-the-art of additive manufacturing (AM) can be classified into three categories: direct digital manufacturing, free-form fabrication, or 3D printing as discussed by the authors.Abstract:
This paper reviews the state-of-the-art of an important, rapidly emerging, manufacturing technology that is alternatively called additive manufacturing (AM), direct digital manufacturing, free form fabrication, or 3D printing, etc. A broad contextual overview of metallic AM is provided. AM has the potential to revolutionize the global parts manufacturing and logistics landscape. It enables distributed manufacturing and the productions of parts-on-demand while offering the potential to reduce cost, energy consumption, and carbon footprint. This paper explores the material science, processes, and business consideration associated with achieving these performance gains. It is concluded that a paradigm shift is required in order to fully exploit AM potential.read more

Linking microstructure and processing defects to mechanical properties of selectively laser melted AlSi10Mg alloy
Nicolas Larrosa,Wei Wang,N. Read,Michael H. Loretto,Chris Evans,James Carr,U. Tradowsky,Moataz M. Attallah,Philip J. Withers +8 more
TL;DR: In this paper, the authors analyzed the relationship between the monotonic and cyclic behavior of cylindrical AlSi10Mg (CL31 AL) samples fabricated by Selective Laser Melting (SLM) to the build direction, the presence of manufacturing defects (pores, voids, oxides, etc.) and the beneficial effect of post-processing (T6 and hot isostatic pressing (HIP) treatments).

Microstructure and Mechanical Properties of Wire and Arc Additive Manufactured Ti-6Al-4V
TL;DR: In this paper, the macrostructure, microstructure and mechanical properties of a Ti-6Al-4V alloy after WAAM deposition have been investigated, and the average yield and ultimate tensile strengths of the as-deposited material were found to be slightly lower than those for a forged Ti- 6Al 4V bar (MIL-T 9047), however, the ductility was similar and the mean fatigue life was significantly higher.
