“…34,37 This is consistent with the limited available research studies regarding the corrosion characteristics of AMed copper-based alloys. [38][39][40][41][42][43][44][45][46][47][48] Thus, the following discussions aim to provide a concise overview of AM technologies that have been utilized in previously published reports dealing with the corrosion properties of AMed NABs and other 3D printed Cu-based alloys.…”

“…[13][14][15] Moreover, recent advances have substantially supported the use of various wire materials such as aluminum, [16][17][18] titanium, [19][20][21] and nickel alloys. [22][23][24][25] However, the path generation in the arc-based metal AM is still based on a point-by-point or layer-by-layer manufacturing approach. [26][27][28] Thus, their print speed is limited by stepwise material deposition due to the time of solidification and cooling of molten metals during the printing process.…”

In metal additive manufacturing (AM), arc plasma is attracting attention as an alternative heat source to expensive lasers to enable the use of various metal wire materials with a high deposition efficiency. However, the stepwise material deposition and resulting limited number of degrees of freedom limit their potential for high-throughput and large-scale production for industrial applications. Herein, a high-throughput metal 3D printing pen (M3DPen) strategy is proposed based on an arc plasma heat source by harnessing the surface tension of the molten metal for enabling continuous material deposition without a downward flow by gravity. The proposed approach differs from conventional arc-based metal AM in that it controls the solidification and cooling time between interlayers of a point-by-point deposition path, thereby allowing for continuous metal 3D printing of freestanding and overhanging structures at once. The resulting mechanical properties and unique microstructures by continuous metal deposition that occur due to the difference in the thermal conditions of the molten metal under cooling are also investigated. This technology can be applied to a wide range of alloy systems and industrial manufacturing, thereby providing new possibilities for metal 3D printing.
