High‐Throughput Metal 3D Printing Pen Enabled by a Continuous Molten Droplet Transfer (Adv. Sci. 6/2023)

Metal 3D Printing Pen In article number 2205085, Young Tae Cho and co-workers present a novel concept of a high-throughput metal 3D printing process by continuous molten droplet transfer based on an arc plasma heat source. Beyond the stepwise material deposition and a limited degree of freedom in conventional metal additive manufacturing, the proposed technology enables continuous metal deposition of freestanding and overhanging structures in 3D space by harnessing the surface tension of the molten metal. This work provides new perspectives and versatility on metal additive manufacturing.
