“…[24][25][26][27][28] The powder-bed technique has shown the admirable capacity to produce components with high accuracy, required material selection and excellent mechanical properties. [29][30][31] The SLM system utilises a focused laser beam, usually a Yb: YAG fibre laser, to melt the powder bed, and the powder is fed from a supply container as displayed in Fig. 1a.…”

Additive manufacturing is an emerging technology that challenges traditional manufacturing methods. However, the corrosion behaviour of additively manufactured parts must be considered if additive techniques are to find widespread application. In this paper, we review relationships between the unique microstructures and the corresponding corrosion behaviour of several metallic alloys fabricated by selective laser melting, one of the most popular powder-bed additive technologies for metals and alloys. Common issues related to corrosion in selective laser melted parts, such as pores, molten pool boundaries, surface roughness and anisotropy, are discussed. Widely printed alloys, including Ti-based, Al-based and Fe-based alloys, are selected to illustrate these relationships, and the corrosion properties of alloys produced by selective laser melting are summarised and compared to their conventionally processed counterparts.

Uniform spherical graphene/monocrystal-copper powder is fabricated by melting bulk laminated composite. Graphene, in the form of reduced graphene oxide (rGO), is uniformly dispersed on the surface of monocrystal Cu particle. A mechanism is proposed based on liquid/solid interface interaction combining the surface energy minimization of liquid Cu and low wettability of molten Cu on graphene. The rGO/Cu composite powder exhibits good sphericity, and the size distribution could be controlled by the amount of rGO.

“…Over the past several years, there have been a plethora of reviews that analyze and summarize the state of the art of metal and alloy processing by means of 3D printing and additive manufacturing (AM). As exemplified in the related literature, these two terms are now used interchangeably [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. The whole spectrum of additive manufacturing, including the wide range of stereo-lithography processes, which include polymers, ceramics, and metallic materials, is estimated to encompass an economic valuation exceeding $10B (in 2017) worldwide.…”

Applications and examples of light and electron micrographs illustrating microstructures, which describe metallurgical phenomena in 3D printing/additive manufacturing of metal and alloy products and components, are presented along with extensive process and processing parameter descriptions and review. Examples include microstructures that have defined turbine blade fabrication and optimization over the past half century, including contemporary electron beam melting fabrication of turbine blade alloys and other novel microstructures and architectures, which result from layer by layer, nonequilibrium melt solidification and epitaxial growth involving powder bed laser and electron beam fabrication. Phase transformations and second-phase formation by rapid cooling in metal and alloy components fabricated by laser and electron beam melting technologies are illustrated for a range of high-temperature materials. Using a range of examples, the advantages of fabricating complex (especially porous) biomedical and related commercial products are described. Prospects for future developments of direct 3D metal and alloy droplet printing, as a key component of the digital factory of the future, are described. This technology is compared with more conventional solidification and powder bed layer building thermo-kinetics, especially in the context of large structure and component fabrication.
