Abstract Scope |
Lattice structures have been pivotal in advancing the field of lightweight and efficient material design, particularly in aerospace and automotive applications. This study explores the advanced capabilities of Drop-on-Demand Molten Metal Jetting (MMJ) for the support-free fabrication of strut-based lattice structures. The burst-mode jetting strategy involves ejecting a specific number of droplets at high frequency at the same location on a substrate, forming a larger-sized droplet. By manipulating the number of drops per burst, frequency, stepover distance, and pause time, this technique facilitates the fabrication of high strength lattice struts with varied diameters and inclination angles. Numerical simulations validated with experimental results will compare the microstructure and mechanical performance of lattices printed with varying diameters and inclination angles. |
