Abstract Scope |
Single-nozzle Molten Metal Jetting (MMJ) systems face limited industrial adoption due to low mass deposition rates. To address this challenge, we introduce a breakthrough multi-nozzle MMJ system featuring independently addressable nozzles with adjustable pitch from 1-30mm. A low-temperature prototype system is built and tested with molten Tin as a model fluid. Preliminary results demonstrate stable, tunable, and repeatable jetting from multiple nozzles without crosstalk. We discuss future strategies for multi-nozzle systems, covering synchronized/sequential jetting, toolpath optimization, and the future potential for high-temperature multi-nozzle systems. This approach represents a significant advancement in MMJ technology, offering order-of-magnitude increases in deposition rates while maintaining fine feature resolution. |
