Abstract Scope |
Multi-nozzle molten metal jetting (MMJ) lays the foundation for high-throughput metal additive manufacturing that aligns with industry needs. However, coordinated jetting from multiple nozzles introduces challenges in toolpath planning. Conventional multi-nozzle concurrent deposition strategies use bitmap images for area deposition. However, bitmap-based droplet placement can produce rough pixelated surface contours, which are detrimental to mechanical properties. In this work, we present a toolpath planning strategy using a 4-axis motion stage designed for multi-nozzle concurrent molten metal droplet deposition. The proposed algorithm improves the surface finishing while increasing the deposition rate of the MMJ process. We will present the methodology to develop the 4-axis motion for the concurrent jetting process and demonstrate the generated toolpath for an 8-nozzle MMJ system. This work represents the first toolpath planning strategy for 4-axis multi-nozzle MMJ processes. |
