“…Yet, studies published over the last few months have started to bring new insights in that respect. Leon et al have compared the corrosion resistance of LBM AlSi10Mg with gravity cast A360.2 of a very similar chemical composition. They found that LBM AlSi10Mg exhibited slightly reduced corrosion rates in a 3.5% NaCl solution in comparison with its cast counterpart.…”

The fusion-based additive manufacturing of Al alloys has been developing at an ever faster pace since early 2015, after a comparatively slow start with respect to other metallic materials. This paper reviews the recent developments with the aim of identifying challenges and opportunities for future work. Additive Al components possess strongly out-of-equilibrium microstructures resulting in potentially enhanced mechanical properties. A deeper understanding of the thermal history during fabrication, the design of new high strength alloys and the development of better adapted post-processing procedures are still needed to take full advantages of the specificities of additive manufacturing.

Metal additive manufacturing (AM) is an innovative manufacturing technique, which builds parts incrementally layer by layer. Thus, metal AM has inherent advantages in part complexity, time, and waste saving. However, due to its complex thermal cycle and rapid solidification during processing, the alloys well suit and commercially used for metal AM today are limited. Therefore, it is important to understand the alloying strategy and current progress with materials performance to consider alloy development for metal AM. This review presents the current range of alloys available for metal AM, including titanium, steel, nickel, aluminum, less common alloys (including Mg alloys, metal matrix composites alloys, and low melting point alloys), and compositionally complex alloys (including bulk metallic glasses and high entropy alloys) with a focus on the relationship between compositions, processing, microstructures, and properties of each alloy system. In addition, some promising alloy systems for metal AM are highlighted. Approaches for designing and optimizing new materials for metal AM have been summarized.

“…The growing interest in additive manufacturing (AM) technology in the last decade has been largely due to the inherent advantages of this technology in terms of creating highly complex geometries in a relatively short time [1][2][3][4][5][6]. Currently, most relevant production and research activities focus on 3D printing processes using powder bed technology (PBT), such as selective laser melting (SLM) and electron beam melting (EBM) [7].…”

: Current additive manufacturing (AM) processes are mainly focused on powder bed technologies, such as electron beam melting (EBM) and selective laser melting (SLM). However, the main disadvantages of such techniques are related to the high cost of metal powder, the degree of energy consumption, and the sizes of the components, that are limited by the size of the printing cell. The aim of the present study was to evaluate the environmental behavior of low carbon steel (ER70S-6) produced by a relatively inexpensive AM process using wire feed arc welding. The mechanical properties were examined by tension testing and hardness measurements, while microstructure was assessed by scanning electron microscopy and X-ray diffraction analysis. General corrosion performance was evaluated by salt spray testing, immersion testing, potentiodynamic polarization analysis, and electrochemical impedance spectroscopy. Stress corrosion performance was characterized in terms of slow strain rate testing (SSRT). All corrosion tests were carried out in 3.5% NaCl solution at room temperature. The results indicated that the general corrosion resistance of wire arc additive manufacturing (WAAM) samples were quite similar to those of the counterpart ST-37 steel and the stress corrosion resistance of both alloys was adequate. Altogether, it was clearly evident that the WAAM process did not encounter any deterioration in corrosion performance compared to its conventional wrought alloy counterpart.
