Abstract Scope |
The Molten Metal Jetting (MMJ) printing process is highly sensitive to drop mass deviations which can lead to poor part quality. The decay in drop mass throughout the printing process in an Aluminum-graphite system is quantified and the potential effect of nozzle clogging is investigated. Drop mass measurements are taken throughout the printing process. Nozzles are periodically sectioned and the layer growth at the Al-C interface is measured. SEM analysis of the nozzles shows a clear growth of an interfacial layer during printing. The formation of this layer may create an unintended reduction in effective nozzle diameter leading to a decay in drop mass. Understanding the potential causes of drop mass reduction is critical to improving the performance and reliability of MMJ systems. |
