Abstract

A model is proposed to predict the geometry of traces generated by molten metal droplet deposition on a flat solid surface. The model also allows the determination of the nozzle displacement that ensures neither droplet buildup nor printed trace discontinuity as a function of impinging droplet size and drop-to-drop and drop-to-substrate contact angles. Experiments performed with Field's alloy droplets and experiments by other authors are used to validate the model. The proposed model significantly improves the predictions for the geometry of the traces obtained using a non-volume-conservative model.

期刊介绍： Materials and Design is a multi-disciplinary journal that publishes original research reports, review articles, and express communications. The journal focuses on studying the structure and properties of inorganic and organic materials, advancements in synthesis, processing, characterization, and testing, the design of materials and engineering systems, and their applications in technology. It aims to bring together various aspects of materials science, engineering, physics, and chemistry. The journal explores themes ranging from materials to design and aims to reveal the connections between natural and artificial materials, as well as experiment and modeling. Manuscripts submitted to Materials and Design should contain elements of discovery and surprise, as they often contribute new insights into the architecture and function of matter.
