| Abstract Scope |
Designing lightweight biomedical materials with optimal mechanical properties is a challenge. This study focuses on mimicking the flexural strength and toughness of spicules. Spicule-inspired structures were fabricated using stereolithography (SLA) 3D printing. The influence of parameters such as wall thickness, layer number, and core diameter on mechanical properties was investigated. Concentric cylindrical structures (CCSs) with fewer than five layers exhibited comparable or higher flexural strength than solid rods, resembling natural spicules. CCSs also demonstrated significantly improved toughness compared to solid rods. Notably, CCSs exhibited diverse crack propagation patterns and enhanced resistance to failure under bending tests. This research showcases the potential of mimicking spicule structures and utilizing concentric cylindrical layers in transforming brittle structures into flexible ones for lightweight, load-bearing applications. |
