| Abstract Scope |
Selective Laser Sintering (SLS) has emerged as a revolutionary method in additive manufacturing, facilitating the manufacturability of intricate lattice structures notable for their high stiffness-to-weight ratios. However, enhancing the mechanical robustness of these structures remains a significant challenge, limiting their practical applications in demanding sectors such as aerospace and automotive industries. This study addresses the critical research gap in enhancing mechanical properties, specifically compressive strength, of SLS-printed lattice structures through the innovative integration of Nylon 12 (PA12) and thermoset resins layered composites. Additionally, the impact of dispersing fibers within the thermoset matrices is investigated to further improve the composites’ energy dissipation capabilities. Research findings indicate that optimal ratios of PA12 to thermoset resins increase compressive yield strength by up to 221%, compared to pure PA12. Ongoing tests with various thermoset resins and fiber-reinforced matrices suggest potential pathways for tuning the mechanical properties of these structures to meet specific application requirements. |
