Abstract Polylactide (PLA) biocomposite filaments containing hemp hurd (HH) of variable particle size were evaluated in comparison with injection‐molded counterparts using single/twin screw extrusion this study. HH (35, 50, and 160 μm) was parametrically investigated for its efficacy within PLA/HH biocomposites fused filament fabrication (FFF)‐printed parts by assessing effect on performance through rheological, microstructural, mechanical, surface finish analyses. In addition, melt flow indexing, rheometry, scanning electron microscopy, mechanical testing, x‐ray computed tomography utilized to analyze microstructure, performance, roughness. With an increase the HH, corresponding showed increased flowability, specimens impact strength. The FFF printing presented no challenges, properties enhanced a smaller than printed layer thickness. Compared parts, FFF‐printed samples higher considerable potential over their injection molded alternatives low‐volume specialized applications. Highlights (PLA)/hemp different sizes developed. Melt strength when increased. 3D‐printed part porosity roughness Higher parts. exhibited

The repair of secondary critical bone defects is an international medical challenge. Bone tissue engineering provides methods and technology for repair. regeneration mechanism serves as inspiration the material structural design scaffolds. In terms materials, this review draws from biological characteristics host cells in osteogenic microenvironment (including osteoblast lineage, vascular cell inflammatory cells, etc.), reviewing regulatory mechanisms self-healing proposing autonomous living materials scaffolds which prepared by in-situ manufacturing. Autonomous regulate migration, proliferation differentiation real time releasing steadily long-term. Regarding structure, we functional role natural structures homeostasis, providing insights into bone-inspired Due to conflict between mechanical properties ability, proposes assembled They can prolong half-life provide support attachment points new growth, autonomously microenvironment. have potential advance research progress field pave way novel clinical treatments.
