| Abstract Scope |
In the realm of lightweight biomedical materials, achieving optimal mechanical properties presents a notable challenge. This study focuses on emulating the flexural strength and toughness exhibited by spicules. By employing stereolithography (SLA) 3D printing, spicule-inspired structures (SISs) were created, allowing investigation into the influence of parameters like wall thickness, layer count, and core diameter on mechanical performance. Remarkably, SISs comprising fewer than five layers demonstrated comparable or superior flexural strength to solid rods, effectively mimicking natural spicules. SISs further showcased significantly enhanced toughness and exhibited diverse crack propagation patterns, enhancing resistance to failure in bending tests. These findings underscore the potential of mimicking spicule structures and leveraging concentric cylindrical layers to transform brittle structures into flexible ones suitable for lightweight applications necessitating load-bearing capabilities. |
