| Abstract Scope |
Biomimetic nanocomposite architectures offer a promising strategy for overcoming the mechanical limitations of conventional additively manufactured scaffolds. This work presents the design and fabrication of a curvature-guided body-centered cubic (BCC) lattice reinforced with silicon carbide (SiC) nanoparticles. Inspired by the anisotropic morphology of trabecular bone, the lattice incorporates smooth curved junctions and controlled pore architectures to improve stress distribution and structural integrity while maintaining printability. Resin–SiC nanocomposite suspensions containing 0.5–5 wt% SiC were systematically optimized through curing kinetics and sedimentation stability to establish a robust processing window for high-resolution micro-DLP printing. SEM and EDS analyses confirmed uniform nanoparticle dispersion and accurate feature reproduction. Mechanical characterization demonstrated significant enhancement in compressive performance with increasing SiC content, with the 5wt% nanocomposite exhibiting the highest strength (44.87MPa). This study establishes a processing–structure–property framework for designing high-performance polymer nanocomposites with biomimetic architectures, offering opportunities for advanced lightweight structures for biomedical applications. |
