Metal Additive Manufacturing: A Review
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

Plastic anisotropy of additively manufactured maraging steel: Influence of the build orientation and heat treatments
TL;DR: In this article, the combined effect of three primary additive manufacturing (AM) build orientations (0°, 45°, and 90°) and an extensive array of heat treatment plans on the plastic anisotropy of maraging steel 300 (MS1) fabricated on the EOSINT M280 Direct Metal Laser Sintering (DMLS) system was investigated.

A comprehensive review of extrusion-based additive manufacturing processes for rapid production of metallic and ceramic parts
Kedarnath Rane,Matteo Strano +1 more
TL;DR: The extrusion-based additive manufacturing (EAM) technique is recently being employed for rapid production of metals and ceramics components as mentioned in this paper, which involves extruding the metal or ceramic material in solid powder form mixed with a binder (i.e., an expendable viscous fluid), which is removed from the part after 3D printing.

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.
