Wire–powder–arc additive manufacturing (WPA-AM) process The WPA-AM system we built is shown in Fig. 1 . This system could select and adjust different kinds and contents of powders, combine with metal wire, and manufacture the MMC components of user-defined structures.
The powder is perfectly spherical and very clean. PREP is best for coarser powder; however, new plants use higher RPM systems that can decrease the particle size to better suit Additive Manufacturing. This
Powder bed fusion (PBF) is a 3D printing method that joins powdered material point by point using an energy source, typically a laser beam or an electron beam. Powder bed fusion is one of the most common 3D printing techniques used for industrial additive manufacturing (AM). PBF is possible with both metals and polymers, although
Atomisation is a way to make metal powder, but not the only way. The choice of powder should be matched with the AM process – it is not a case of ''one size fits all''. Of course, we are not implying that atomisation is not the most effective way to make metal powders, as most of the industry is facilitated to do so.
The metal powder manufacturing process is based on a state‐of‐the art gas atomization method with Argon or Nitrogen, with VIM (Vacuum Induction Melting).

Abstract. The cohesive effect between particles is crucial in influencing the quality of the powder layer in additive manufacturing (AM), which will induce low reproducibility of the subsequent particle fusion process and degrade the performance of final products. In this work, the phenomenon and mechanism of interparticle cohesive
Powder-based additive manufacturing, e.g., powder bed fusion, has attracted significant attention due to its advantages of fast prototyping, superior design and geometrical flexibility [27, 46, 48]. This technique allows near-net-shape production, enabling quick production of exact and customized parts, saving time and reducing waste.
To date, the most effective ways to achieve CET in a variety of powder fusion-additive manufacturing (PF-AM) processes include variation of processing conditions 3,12,13,14, laser beam shaping 15
